Anti-angiogenesis efficacy of the aqueous extract of Allium sativum and its combination with melatonin in an animal model: in vivo and ex vivo studies

To better understand Allium sativum’s anti-angiogenesis activity, we undertook this study to examine its effect on the ex vivo rat aortic ring and the in vivo chick chorioallantoic membrane. Additionally, we compare Allium sativum’s anti-angiogenesis activity to melatonin and study the benefits of their combination. The study included six albino male rats (aged 5–7 weeks). The rats were euthanized, and then the thoracic aorta was removed and cut into rings that were 1 mm thick. The study was divided into three groups: a negative control (1% v/v DMSO), a positive control (100 μg/mL melatonin), and an aqueous Allium sativum extract. The test compounds were subjected to serial dilutions to obtain 100, 50, 25, 12.25, and 6.25 μg/mL concentrations. In addition, the in vivo chick chorioallantoic membrane was also undertaken. Allium sativum and melatonin significantly inhibited the rat aorta ring; the IC50 was calculated (IC50 = 8.04 for Allium sativum and 3.313 for melatonin). The zone of inhibition for melatonin, Allium sativum, and the combination showed that the combination had the strongest effect on the CAM assay. This zone scored (++) and (+++), respectively. In conclusion, the aqueous extract of Allium sativum provides a potent anti-angiogenesis effect, and its combination with melatonin had a synergistic effect, further enhancing its anti-angiogenesis effect.

Antibacterial Activity of the Allium sativum Crude Extract against Methicillin-resistant Staphylococcus aureus

Garlic contains various components, such as allicin, ajoenes, and allyl sulfides, which are organosulfur compounds. It exhibits antimicrobial activities in all forms, including garlic powder, garlic extract, and garlic oil. Additionally, it exerts anti-inflammatory, antibacterial, antibiofilm, and antifungal effects. The drastic increase in drug-resistant organisms worldwide, especially methicillin-resistant Staphylococcus aureus (MRSA) strains, has led to treatment failure in various infectious diseases. To overcome this issue, we aimed to assess the antibacterial activity of garlic extract against MRSA and explore its action mechanism against penicillin-binding proteins (PBPs) in this study. Mueller–Hinton agar was used for the agar well diffusion test. Moreover, bactericidal activity was determined using the Mueller–Hinton agar and spot tests. Molecular docking was performed using AUTODOCK to evaluate the PBP-binding ability of allicin. A wide zone of inhibition was observed for MRSA, and molecular docking revealed a strong interaction between PBP3 of S. aureus and allicin. Overall, our findings revealed the antibacterial activity of garlic extract against MRSA, a prevalent gram-positive coccus causing healthcare-associated infections. In addition to its affordability, the beneficial effects of garlic suggest its therapeutic potential for MRSA treatment in combination with cefoxitin.

Aqueous extract-mediated green synthesis of CuO nanoparticles: Potential anti-tuberculosis agents.

The emergence of drug-resistant strains in tuberculosis treatment underscores the urgency for novel therapeutic approaches. This study investigates the anti-tuberculosis activity of green-synthesized copper oxide (CuO) nanoparticles (NPs) using garlic and astragalus extracts. The physicochemical characterization of the nanoparticles confirms successful synthesis, followed by assessment of their antibacterial properties and safety profile. Rats infected with Mycobacterium tuberculosis are treated with nanocomposites derived from garlic extract at doses of 50 mg/kg and 100 mg/kg body weight. Evaluation includes the analysis of Early secreted antigenic target of 6 kDa (ESAT-6) expression and confirmation of antibodies through molecular assays. Administration of garlic and nanocomposites demonstrates significant inhibitory effects on tuberculosis progression in rats, validated by safety assessments and antibacterial efficacy. Notably, the 100 mg/kg dosage exhibits pronounced mitigation of tuberculosis-induced oxidative stress and lung damage. In conclusion, the combined administration of garlic extracts and green-synthesized nanocomposites shows promising efficacy in reducing tuberculosis infection, highlighting a potential avenue for anti-tuberculosis interventions.

This research contributes valuable insights into the potential of herbal remedies as adjuncts or alternatives to conventional treatments, paving the way for further exploration in infectious disease management and prevention strategies.

Effectiveness of plant extracts against cumin blight (Alternaria burnsii)

Cumin (Cuminum cyminum L.) is an important seeds spice crop at world level and India is the leading producer (70% of world production), consumer and exporter of cumin in the world. Almost 80% of the crop cultivated is consumed in India. This crop is affected by major three fungal pathogens (viz., wilt, blight and powdery mildew), among them blight (Alternaria burnsii) is considered as most important one. Among the phytoextracts tested, the majority were found effective in inhibiting the radial growth of test fungus and highest inhibition was in tulsi, akda and garlic extract at 10 per cent concentration which recorded 73.76, 70.63 and 70.09 per cent inhibition, respectively.

Sustainable Agrochemical Exploitation of Ligurian Aromatic Plant Ecotypes.

The characterization of local improved varieties as well as the reduction of synthetic chemical fertilizers are sustainable approaches in the vision of a new precision Farming. Aim of our study was to improve the geographical characterization of local ecotypes and to identify peculiar features of new crops in terms of bioactive compounds. NMR and LC-MS metabolite profiling approaches followed by multivariate data analysis were applied to characterize local rosemary and garlic ecotypes. With the aim of applying for a protected designation of origin, orthogonal partial least squares discriminant analysis (OPLS-DA) was used to identify representative sensory quality indicators for Vessalico garlic and rosemary "Eretto Liguria" local ecotypes, Variable Influence on Projections (VIP) values of OPLS-DA indicated six metabolites as quality indicators for Vessalico garlic and sixteen metabolites as quality indicators for rosemary "Eretto Liguria". Finally, to discover and utilize new ecotypes in a sustainable way, Vessalico garlic extracts antiviral activity, previously evaluated against Tomato brown rugose fruit virus (ToBRFV), a Tobamovirus affecting tomato crops, was extended to Pepino mosaic virus (PepMV) with positive results.

Aged garlic extract preserves beta-cell functioning via modulation of nuclear factor kappa-B (NF-κB)/Toll-like receptor (TLR)-4 and sarco endoplasmic reticulum calcium ATPase (SERCA)/Ca2+ in diabetes mellitus

BackgroundPeripheral insulin resistance and compromised insulin secretion from pancreatic β-cells are significant factors and pathogenic hallmarks of diabetes mellitus (DM). NF-κβ/TLR-4 and SERCA/Ca2+ pathways have been identified as potential pathways regulating insulin synthesis by preserving pancreatic β-cell functioning. The current study aimed to evaluate the therapeutic effect of aged garlic extract (AGE) against DM in a streptozotocin (STZ)-induced rat model with particular emphasis on pancreatic β-cell functioning.MethodsAGE was characterized by gas chromatography-mass spectrometry (GC-MS), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) to evaluate its physio-chemical characteristics followed by in-vitro anti-diabetic and antioxidant potential. This was followed by the induction of DM in laboratory animals for investigating the therapeutic action of AGE by evaluating the role of NF-κβ/TLR-4 and the SERCA/Ca2+ pathway. The parameters assessed in the present experimental setup encompassed antioxidant parameters, metabolic indicators, insulin concentration, intracellular calcium levels, apoptotic markers (CCK-8 and Caspase Glo-8), and protein expression (P-62 and APACHE-II).ResultsAGE characterization by SEM, GC-MS, and X-ray diffraction (XRD) revealed the presence of phenylalanine, alliin, S-allylmercaptocysteine (SAMC), tryptophan, 1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid as major bioactive constituents of AGE. Metabolic studies, including intraperitoneal glucose tolerance test (IPGTT), revealed significantly lower blood glucose levels in the AGE group compared to the disease control group. In contrast, the intraperitoneal insulin tolerance test (ITT) exhibited no significant difference in insulin sensitivity between the AGE supplementation group and the DM control group. Interestingly, AGE was found to have no significant effect on fasting glucose and serum insulin levels. In contrast, AGE supplementation was found to cause significant hypoglycaemia in postprandial blood glucose and insulin levels. Importantly, AGE causes restoration of intracellular Ca2+ levels by modulation of SERCA/Ca2 functioning and inhibition NF-κB/TLR-4 pathway. AGE was found to interact with and inhibit the DR-5/ caspase-8/3 apoptotic complex. Furthermore, microscopic studies revealed degeneration and apoptotic changes in pancreatic β-cells of the DM control group, while supplementation of AGE resulted in inhibition of apoptotic pathway and regeneration of pancreatic β-cells.ConclusionThe current study suggests that AGE enhance glucose homeostasis by exerting their effects on pancreatic β-cells, without ameliorating peripheral sensitivity. Moreover, AGEs promote an increase in β-cell mass by mitigating the apoptosis of pancreatic β-cells. These findings suggest that AGE could aid in developing a viable alternative therapy for diabetes mellitus (DM).

Toward a push–pull strategy against invasive snails using chemical and visual stimuli

Four invasive Mediterranean snails, i.e., Theba pisana (Müller, 1774), Cernuella virgata (da Costa, 1778), Cochlicella acuta (Müller, 1774) and Cochlicella barbara (Linnaeus, 1758) cost $170 million yearly to the grain industry in Australia. Their impact is mainly due to their estivation behavior: snails climb on cereal and legume stalks to rest during summer, which coincides with harvest, causing grain contamination issues in crops such as wheat, barley and canola. Diverse management methods have been developed to regulate snail populations, with limited success. Our study investigates the potential for a push–pull strategy to divert invasive snails from cultivated fields. A “push” part (i.e. using a repellent stimuli) was based on the use of a chemical deterrent repelling snails from the cultivated field, and a “pull” part (i.e. using an attractive stimuli) was based on offering attractive estivation supports for snails to aggregate outside the cultivated field. First, artificial estivation supports of different colors were tested under laboratory and field conditions and showed that red supports were the most attractive for these snails. Second, different substances were tested as potential snail deterrents (garlic, coffee, coffee grounds, copper). Garlic extracts were the most powerful snail deterrent and were shown to effectively protect an estivation support and food source from snails under laboratory conditions. These results, which were highly consistent for the four species, illustrate the potential of a push–pull strategy against invasive snails in Australia. It is the first attempt to develop a push–pull strategy relying on both visual and chemical stimuli to achieve results, as well as manipulating the estivation behavior of a pest.

Among Other Tissues, Short-Term Garlic Oral Treatment Incrementally Improves Indicants of Only Pancreatic Islets of Langerhans Histology and Insulin mRNA Transcription and Synthesis in Diabetic Rats.

The source, mRNA transcription, and synthesis of insulin in the pancreas, in addition to the bile duct and liver, in streptozotocin (STZ)-induced diabetic rats (DR) in response to garlic oral treatment are not yet clear. This study investigated the accumulative effects of continued garlic oral treatment on changes in the pancreas, bile duct, and liver with regards to: 1-Insulin mRNA transcription, synthesis, and concentration in relation to changes in serum insulin (SI); 2-Insulinogenic cells insulin intensity and distribution, proliferation, and morphology. Fasting blood glucose (FBG) and insulin concentration in serum and pancreas (PI) and sources and mRNA transcription in the pancreas, bile duct, and liver in normal rats given normal saline (NR-NS) and DR given either NS (DR-NS) or garlic extract (DR-GE) before and after 1, 4, and 8 weeks of oral treatment were examined. Compared to NR-NS, DR-NS showed a significant increase in FBG and reductions in SI and PI and deterioration in islets histology, associated pancreatic insulin numerical intensities, and mRNA transcription. However, compared to DR-NS, the targeted biochemical, histological, and genetic variables of DR-GE were significantly and incrementally improved as garlic treatment continued. Insulin or its indicators were not detected either in the bile duct or the liver in DR-GE. 8 weeks of garlic oral treatment is enough to incrementally restore only pancreatic islets of Langerhans insulin intensity and insulinogenic cells proliferation, morphology, and distribution. These indices were associated with enhanced pancreatic insulin mRNA transcription and synthesis. Eight weeks of garlic treatment were not enough to stimulate insulinogenesis in either the bile duct or the liver.

Optimizing Tomato Health: Holistic Approach to Early Blight Disease Management

An experiment was conducted to evaluate the effect of fungicide (mancozeb) and botanicals against early blight of tomato caused by Alternaria solani at the experimental field and glasshouse of Plant Pathology department, College of Agriculture, Pune, Maharashtra, during Kharif season (2019-2020). Six treatments including control with four replications were taken up using Randomized Block Design RBD. Growth inhibition of fungus Alternaria solani causing early leaf blight of tomato was studied in vivo for determining the efficacy of one fungicide and eight botanicals. Exploring possibility of managing A. solani by use of botanicals revealed that the clove extract of garlic was the best followed by neem leaf and ginger rhizome extract showing highest growth inhibition of the fungus. Among the plant leaf extracts, garlic clove extract @10% was found effective to inhibit the growth of pathogen i.e. 64.60% Per cent disease control PDC (glasshouse trial) and 51.85% PDC (open Field trial). The contact fungicide Mancozeb@0.25% showed disease control of 75.52% (Glasshouse trial) and PDC of 70.34% (Field trial) in in vivo condition. Presently many farmers are using chemicals for control of early blight of tomato however, they cause health hazards. Therefore, this investigation provides valuable insights for farmers in selecting suitable plant extracts to control early blight of tomatoes.

Unveiling Garlic's Arsenal: A Comprehensive Review of Antifungal and Antibacterial Cream

Garlic (Allium sativum) has long been recognized for its medicinal properties, particularly its antimicrobial effects. In this comprehensive review, we explore the therapeutic potential of garlic in the formulation of creams targeting fungal and bacterial infections. We discuss the rising prevalence of fungal infections, particularly those caused by Candida species, and the challenges they pose in healthcare settings. Furthermore, we delve into the diverse biochemical composition of garlic, including sulfur compounds, enzymes, carbohydrates, minerals, amino acids, flavonoids, and vitamins, which contribute to its antimicrobial activity. The synthesis of allicin, a key bioactive compound in garlic, and its mechanism of action against various pathogens are elucidated. Additionally, we examine the dermatological applications of topical garlic in treating fungal skin infections, wound healing, antioxidant protection, UVB shielding, and anti-aging benefits. Clinical evidence supporting the efficacy of garlic extracts in managing viral skin conditions is also discussed. Finally, we highlight the need for further research and clinical trials to fully explore garlic's therapeutic potential, safety profile, and optimal formulations, thereby enhancing patient outcomes in the management of infectious diseases.

The potential modulatory impact of garlic-selenium nanoparticles coated with synthetic tocopherol polyethylene glycol-succinate against lead acetate toxicity in male rabbits

Toxic heavy metal lead enters in the environment due to industrial and anthropogenic activity threatens ecosystems and public health. Natural garlic extract (GE) exhibits antioxidant properties and various applications against several ailments. Therefore, this study scrutinized the protective effects of tocopherol polyethylene glycol succinate-coated garlic selenium (TPGS-GSNP) against lead acetate (LA) toxicity in rabbits. Sixty-four mature male rabbits were involved and divided into 8 equal groups. They received distilled water (negative control; T1), 30 mg/kg bw of LA (positive control; T2), 800 mg/kg bw of GE (T3), GE + LA (T4), 1 mg/kg bw of TPGS-Selenium (T5), TPGS-S + LA (T6), 1 mg/kg bw of TPGS-GSNP (T7), and TPGS-GSNP + LA (T8). Consequently, treatments were administered three times a week for 12 weeks. Following the treatment period, serum oxidant-antioxidant, protein, and lipid profiles, liver and kidney function, histopathological findings of the adrenal, liver, and kidneys, femur bone marrow chromosomal aberrations, and mitotic activity were collected and analysed. LA exposure showed significant reductions in antioxidant levels, organ weights, and mitotic activity while increasing oxidative stress, corticosteroid levels, and chromosomal aberrations. Importantly, TPGS-GSNP administration significantly improved these markers compared to the LA group. In addition, histological analysis revealed structural improvements of the studied organs in the TPGS-GSNP group compared to the LA group, which displayed high cellular necrotic and degenerative changes. In conclusion, synthetic TPGS-GSNP demonstrated higher protective efficacy against LA-induced toxicity compared to natural GE or selenium alone. However, more future studies could be conducted to explore the potential of TPGS-GSNP as an anticancer or immunomodulatory agent.

Effects of Garlic on Breast Tumor Cells with a Triple Negative Phenotype: Peculiar Subtype-Dependent Down-Modulation of Akt Signaling.

Breast cancer includes tumor subgroups with morphological, molecular, and clinical differences. Intrinsic heterogeneity especially characterizes breast tumors with a triple negative phenotype, often leading to the failure of even the most advanced therapeutic strategies. To improve breast cancer treatment, the use of natural agents to integrate conventional therapies is the subject of ever-increasing attention. In this context, garlic (Allium sativum) shows anti-cancerous potential, interfering with the proliferation, motility, and malignant progression of both non-invasive and invasive breast tumor cells. As heterogeneity could be at the basis of variable effects, the main objective of our study was to evaluate the anti-tumoral activity of a garlic extract in breast cancer cells with a triple negative phenotype. Established triple negative breast cancer (TNBC) cell lines from patient-derived xenografts (PDXs) were used, revealing subtype-dependent effects on morphology, cell cycle, and invasive potential, correlated with the peculiar down-modulation of Akt signaling, a crucial regulator in solid tumors. Our results first demonstrate that the effects of garlic on TNBC breast cancer are not unique and suggest that only more precise knowledge of the mechanisms activated by this natural compound in each tumor will allow for the inclusion of garlic in personalized therapeutic approaches to breast cancer.

Botanical extracts improve postharvest quality and extend the shelf life of papaya (Carica papaya L. cv. Shahi)

ABSTRACT Though papaya is a lucrative fruit regarding nutritional, medicinal, and commercial attributes, its susceptibility to postharvest loss may account for ≥ 40%. An experiment was carried out at Khulna University, Bangladesh from April to May 2013 to investigate the effects of botanical extracts on the postharvest physicochemical attributes, intensity, and severity of diseases and shelf life of papaya cv. Shahi. The experiment comprised botanical extracts from onion bulb, neem leaf, garlic bulb, oriental pepper leaf, datura leaf, and control as six treatments and replicated thrice following a completely randomised design (CRD). Among the physicochemical parameters, total soluble solids (TSS), weight loss, and dry matter of papaya fruit increase, and pulp to peel ratio, moisture content decrease gradually during the storage period disregarding treatments. Garlic bulb extract decreases the incidence and severity of postharvest diseases and extends the shelf life by more than 7 days compared to control. Thus, garlic bulb extract can be used for postharvest papaya storage. However, further experiments should be conducted before the final recommendation.

Effect of Garlic Extract on the Erythrocyte as a Simple Model Cell.

Garlic is known to have diverse effects on mammalian cells, being cytotoxic, especially to cancer cells, but also protect against oxidative stress. Mammalian erythrocyte is a simple cell devoid of intracellular organelles, protein synthesis ability, and most signaling pathways. Therefore, examination of the effects of garlic on erythrocytes allows for revealing primary events in the cellular action of garlic extract. In this study, human erythrocytes or erythrocyte membranes were exposed to garlic extract at various dilutions. Hemoglobin oxidation to methemoglobin, increased binding of hemoglobin to the membrane, and formation of Heinz bodies were observed. Garlic extract depleted acid-soluble thiols, especially glutathione, and induced a prooxidative shift in the cellular glutathione redox potential. The extract increased the osmotic fragility of erythrocytes, induced hemolysis, and inhibited hemolysis in isotonic ammonium chloride, indicative of decreased membrane permeability for Cl- and increased the membrane fluidity. Fluorescent probes indicated an increased level of reactive oxygen species and induction of lipid peroxidation, but these results should be interpreted with care since the extract alone induced oxidation of the probes (dichlorodihydrofluorescein diacetate and BODIPY C11). These results demonstrate that garlic extract induces oxidative changes in the erythrocyte, first of all, thiol and hemoglobin oxidation.

Detailed analysis of agro-industrial byproducts/wastes to enable efficient sorting for various agro-industrial applications

Agriculture-based industries generate huge amounts of byproducts/wastes every year, which are not exploited or disposed efficiently posing an environmental problem with implications to human and animal health. Finding strategies to increase the recycling of agro-industrial byproducts/wastes (AIBWs) is a primary objective of the current study. A thorough examination of AIBWs in conjunction with experimental research is proposed to facilitate sorting for various agro-industrial applications and consequently increasing byproduct/waste utilization. Accordingly, two sustainable, locally available sources of AIBWs, namely, wheat bran (WB) and garlic straw and peels (GSP) were studied in detail including content and composition of proteins, phytohormones and nutritional elements, as well as the effect of AIBW extracts on plant and microbial growth. Hundreds of proteins were recovered from AIBW mainly from WBs, including chaperons, metabolite and protein modifying enzymes, and antimicrobial proteins. In-gel assays showed that WB and GSP possess high protease and nuclease activities. Conspicuously, phytohormone analysis of AIBWs revealed the presence of high levels of strigolactones, stimulants of seed germination of root parasitic weeds, as well as indole acetic acid (IAA) and abscisic acid (ABA). Garlic straw extract strongly inhibited germination of the weed Amaranthus palmeri but not of Abutilon theophrasti and all examined AIBWs significantly affected post-germination growth. Bacterial growth was strongly inhibited by garlic straw, but enhanced by WBs, which can be used at least partly as a bacterial growth medium. Thus, an in-depth examination of AIBW characteristics will enable appropriate sorting for diverse agro-industrial applications, which will increase their utilization and consequently their economic value.

Evaluation of Anti‐inflammatory Activity of Garlic Extracts in 3D Bioprinted Skin Equivalents

Ongoing obstacles in preclinical drug testing have raised significant concerns within the pharmaceutical industry. Recently, utilizing the potential of three‐dimensional (3D) bioprinting offers a solution for creating tissue models for screening of the effectiveness and safety of new drugs. In this study, the anti‐inflammatory potential of garlic extracts is assessed, specifically N‐Benzyl‐N‐methyl‐dodecan‐1‐amine (BMDA), using a 3D bioprinted artificial skin model. Comprehensive physicochemical characterization and immunocytochemical analysis demonstrate that the 3D bioprinted skin model exhibits structures and functions resembling human skin. BMDA treatment in a prepared skin model reveals its capacity to mitigate H2O2‐induced oxidative stress and trigger anti‐inflammatory responses. Notably, BMDA reduces the expression of pro‐inflammatory cytokines and chemokines by downregulating NF‐κB and mitogen‐activated protein kinase inflammatory signaling pathways. In summary, our findings highlight the potential of an artificial skin model as a robust platform for the development of new drugs.

Hypothesizing the Green Synthesis of Tamoxifen Loaded Magnetic Nanoparticles for the Treatment of Breast Cancer.

Breast cancer is the second leading cause of death all over the world and is not only limited to females but also affects males. For estrogen receptor-positive breast cancer, tamoxifen has been considered the gold-line therapy for many decades. However, due to the side effects associated with the use of tamoxifen, its use is only limited to individuals in high-risk groups and limits its clinical application to moderate and/or lower-risk groups. Thus, there is a necessity to decrease the dose of tamoxifen, which can be achieved by targeting the drug to breast cancer cells and limiting its absorption to other body parts. Artificial antioxidants used in the formulation preparation are assumed to upsurge the risk of cancer and liver damage in humans. The need of the hour is to explore bioefficient antioxidants from natural plant sources as they are safer and additionally possess antiviral, anti-inflammatory, and anticancer properties. The objective of this hypothesis is to prepare tamoxifen-loaded PEGylated NiO nanoparticles using green chemistry, tumbling the toxic effects of the conventional method of synthesis for targeted delivery to breast cancer cells. The significance of the work is to hypothesize a green method for the synthesis of NiO nanoparticles that are eco-friendly, cost-effective, decrease multidrug resistance, and can be used for targeted therapy. Garlic extract contains an organosulfur compound (Allicin) which has drug-metabolizing, anti-oxidant, and tumour growth inhibition effects. In breast cancer, allicin sensitizes estrogen receptors, increasing the anticancer efficacy of tamoxifen and reducing offsite toxicity. Thus, this garlic extract would act as a reducing agent and a capping agent. The use of nickel salt can help in targeted delivery to breast cancer cells and, in turn, reduces drug toxicity in different organs. This novel strategy may aim for cancer management with less toxic agents acting as an apt therapeutic modality.

Efficacy of edible plant extracts against multi-drug resistant Salmonella serovars in layer flocks

The present study examines the antibacterial effects of edible plants (Neem, Garlic, and Ginger) extracts against Salmonella serovars isolated from layer flocks using phenotypic antimicrobial resistance techniques. The incidence of positive isolates was higher in Dinajpur (13.89%), followed by Thakurgoan (11.91%), Nilphamari (10%), and Panchagarh (8.33%). Organoleptic analysis showed a higher prevalence in the liver (17.86%) compared to the heart (7.14%) and lung (10.72%). Ethanolic extractions were performed from the plants, and the antibacterial activity of these extracts was assessed using the disc diffusion method at concentrations of 80, 100, and 120 mg/mL against multidrug-resistant (MDR) bacteria, which were identified from selected layer flocks using conventional laboratory techniques. These bacteria are resistant to at least two antibiotics. The maximum inhibition zones for Neem, Garlic, and Ginger extracts at 120 mg/mL were 14 mm, 10 mm, and 2 mm, respectively, while the minimum inhibition zones at 80 mg/mL were 10 mm, 3 mm, and none, respectively. Neem leaf extract showed the highest effectiveness against MDR bacteria compared to Garlic and Ginger extracts. Although the organisms were sensitive to ciprofloxacin and colistin, they showed intermediate resistance to levofloxacin and chloramphenicol and resistance to neomycin and kanamycin. When comparing the antibacterial efficacy of resistant antibiotics and plant extracts in vitro, plant extracts showed larger inhibition zones. Therefore, it was concluded that ethanolic Neem leaf extract could serve as an alternative to conventional antibiotics against field isolates of Salmonella spp. in poultry.
