Anaerobically mineralized nitrogen as a potential indicator of the activity and abundance of mycorrhizal fungi in Mollisols

Anaerobically mineralized nitrogen (AN) is a suitable soil health indicator. The AN is sensitive to soil use changes and is related to soil and particulate organic carbon and aggregate stability. This work aims to evaluate the relationship between AN and 1) easily extractable glomalin-related soil proteins; 2) abundance of arbuscular mycorrhizal fungi measured by the number of arbuscular mycorrhizal fungi spores, and 3) arbuscular mycorrhizal fungi activity (root colonization). Soil samples were taken at depths of 0-5 and 5-20 cm from cultivated and uncultivated plots throughout the southeastern province of Buenos Aires. Anaerobically mineralized nitrogen, soil organic carbon, particulate organic carbon, aggregate stability, easily extracted glomalin-related soil proteins and the logarithm of the number of arbuscular mycorrhizal fungi spores (log spores) at 0-5, 5-20 and 0-20 cm depths were determined. In wheat roots, the percentages of total infection and arbuscules at 0-20 cm were measured. At all depths, AN was positively correlated to easily extractable glomalin-related soil proteins (r=0.34-0.65), which is an indicator of arbuscular mycorrhizal fungi activity and abundance. Likewise, AN was positively related to log-spores (r=0.58-0.78), which is an indicator of arbuscular mycorrhizal fungi abundance. However, AN was not related to root colonization (the percentages of total infection and arbuscules) that manifests the activity of arbuscular mycorrhizal fungi at a specific moment. Thus, anaerobically mineralized nitrogen would be an indicator of mid- to long-term changes in arbuscular mycorrhizal fungi abundance and activity (easily extractable glomalin-related soil proteins and log-spores) resulting from soil use. Consequently, the AN would allow monitoring an important aspect of soil microbiological health associated with arbuscular mycorrhizal fungi. However, it is necessary to evaluate the relationships studied in this work in a wider range of soil situations.

Synthesis and evaluation of pyridine-3-carboxamide analogs as effective agents against bacterial wilt in tomatoes

This study focused on developing novel pyridine-3-carboxamide analogs to treat bacterial wilt in tomatoes caused by Ralstonia solanacearum. The analogs were synthesized through a multistep process and their structures confirmed using spectroscopy. Molecular docking studies identified the most potent analog from the series. A specific analog, compound 4a, was found to significantly enhance disease resistance in tomato plants infected with R. solanacearum. The structure–activity relationship analysis showed the positions and types of substituents on the aromatic rings of compounds 4a–i strongly influenced their biological activity. Compound 4a, with a chloro group at the para position on ring C and hydroxyl group at the ortho position on ring A, was exceptionally effective against R. solanacearum. When used to treat seeds, the analogs displayed remarkable efficacy, especially compound 4a which had specific activity against bacterial wilt pathogens. Compound 4a also promoted vegetative and reproductive growth of tomato plants, increasing seed germination and seedling vigor. In plants mechanically infected with bacteria, compound 4a substantially reduced the percentage of infection, pathogen quantity in young tissue, and disease progression. The analogs were highly potent due to their amide linkage. Molecular docking identified the best compounds with strong binding affinities. Overall, the strategic design and synthesis of these pyridine-3-carboxamide analogs offers an effective approach to targeting and controlling R. solanacearum and bacterial wilt in tomatoes.

Wearable flexible Kapton-graphene electromagnetic sensors

This research is dedicated to the development of a new technology for a quick diagnosis of virial virus, using electromagnetic technology facilitated by either a Rectangular Patch Resonator (RPR) or a Wearable Flexible Sensor (WFS) designed for non-invasive viral disease detection, including Nano-virus, and macro-virus. These devices is tailored for a precise and non-invasive detection of a wide array of viruses. To enhance diagnostic precision, an electromagnetic sensor was meticulously explored and simulated, to be capable of detecting and identifying even the most minuscule viruses. Employing numerical modeling with a focus on the 10 GHz to 20 GHz frequency range. We hold a strong sense of optimism regarding this sensor's potential for non-invasive virus detection. Extensive simulations conducted throughout this study have underscored the WFS's selectivity across all viruses, boasting an exceptional limit of detection and sensitivity. Moreover, the WFS exhibited the capability to distinguish between varying infection percentages, each corresponding to a distinct reflection pattern.

Sodium Tetraborate Induces Systemic Resistance in Watermelon against Stagonosporopsis cucurbitacearum

Imbibing watermelon seeds in 1 mM sodium tetraborate (Na2B4O7) for 24 h systemically protected plants against foliar infection by Stagonosporopsis cucurbitacearum in detached leaves and under greenhouse conditions. The treatment resulted in both a reduction in the overall percentage of leaf infection as well as in the size of lesions. Studies of the mechanisms by which Na2B4O7 protected watermelon showed that there was no direct effect on the S. cucurbitacearum mycelium growth in vitro. On the other hand, plants raised from seeds primed with Na2B4O7 showed a higher frequency of fluorescent epidermal cells compared to the plants treated with water. This indicates that a higher number of cells expressed the hypersensitive response after Na2B4O7 priming. In addition, there was an increase in peroxidase activity and an enhanced accumulation of a 45 kDa acidic peroxidase isoform during the early stages of infection in plants treated with Na2B4O7 compared to plants treated with water and this was positively correlated to the reduction of leaf infection caused by the pathogen. These results indicate that Na2B4O7 is able to induce systemic resistance in watermelon against S. cucurbitacearum by activating the hypersensitive reaction at penetration sites, increasing peroxidase activity and altering the peroxidase isozyme profile. Although each individual response may only have had a minor effect, their combined effects had a reducing effect on the disease.

Unveiling Genetic Variation in Garlic Genotypes in Response to Rust Disease Using RAPD Markers

Garlic (<em>Allium sativum</em>), cultivated worldwide for its medicinal and nutritional value, faces challenges due to diseases caused by various pathogens. In this study, eleven garlic genotypes from Iran and one from China were selected and sown under natural infection rendered by the rust fungus (<em>Puccinia alli</em>) over two consecutive years. Subsequently, disease distribution and severity, percentage of infection and susceptibility of different garlic genotypes to rust disease were investigated. The results showed that genotype Solan was the most susceptible, with disease severity of 30.81%. In comparison, genotypes Aliabad and Bahar were resistant against rust disease with the lowest infection percentages of 13% and 16.37%, respectively. Further, genetic diversity was assessed using random-amplified polymorphic DNA (RAPD) markers. Out of 10 primers used, 95 scorable bands were generated, of which 66 (69.48%) were found to be polymorphic. A dendrogram was constructed based on RAPD polymorphism using the UPGMA method, and the genotypes were separated into six distinct clusters based on Jaccard's coefficient of similarity. Additionally, it was observed that there is no genetic differentiation among the genotypes based on their geographical origin. This study highlights the significant diversity in resistance and susceptibility among garlic genotypes, which can be harnessed in plant breeding programs.

ANTISAPROLEGNIA ACTIVITY OF METHANOLIC EXTRACT OF ZINGIBER OFFICINALE IN BUNNEI (BARBUS SHARPEYI) HATCHERY

Usage of chemicals such as malachite green to disinfect fish eggs in aquaculture has been banned in many countries around the world due to its environmental negative impact. This study aimed to evaluate the Zingiber officinale rhizomes extract as an antifungal agent during incubation period of Bunnei eggs and comparison of its effects with malachite green. For this purpose 24 hours after fertilization, methanolic extract of Zingiber officinale rhizomes in four groups with a concentration of 500, 750, 1000, and 1250 mg/L and three replications per concentration in a (10 minute) bath every 12 hours and malachite green group with a concentration of 0.1 mg/L for (6 minutes) bath was used twice a day and control group without antifungal agents under the same physiochemical conditions as other treatments were tested. The present study showed that the highest percentage of fungal infection was 41.82±0.5 % for the control group and the lowest 0.3±0.5 % was obtained for the treatment of 1250 mg/L of Zingiber officinale rhizomes. Also, the results showed that there were significant differences between treatments of different concentrates of Zingiber officinale rhizomes and with malachite green group in fungal infection, percentage of fertilization and survival do not exist (P>0.05.) No apparent deformity and abnormality were observed in the hatched larvae of Bunnei, so the extract of Zingiber officinale rhizomes with concentration 500 mg /L can be used to disinfect Bunnei eggs during Incubation period and safe material for humans and the environment.

Health Disparities in Patients With Musculoskeletal Injuries: Food Insecurity Is a Common and Clinically Challenging Problem.

Health disparities have important effects on orthopaedic patient populations. Socioeconomic factors and poor nutrition have been shown to be associated with an increased risk of complications such as infection in patients undergoing orthopaedic surgery. Currently, there are limited published data on how food insecurity is associated with medical and surgical complications. We sought to (1) determine the percentage of patients who experience food insecurity in an orthopaedic trauma clinic at a large Level 1 trauma center, (2) identify demographic and clinical factors associated with food insecurity, and (3) identify whether there are differences in the risk of complications and reoperations between patients who experience food insecurity and patients who are food-secure. This was a cross-sectional study using food insecurity screening surveys, which were obtained at an orthopaedic trauma clinic at our Level 1 trauma center. All patients 18 years and older who were seen for an initial evaluation or follow-up for fracture care between November 2022 and February 2023 were considered for inclusion in this study. For inclusion in this study, the patient had to have surgical treatment of their fracture and have completed at least one food insecurity screening survey. Ninety-eight percent (121 of 123) of patients completed the screening survey during the study period. Data for 21 patients were excluded because of nonoperative treatment of their fracture, nonfracture-related care, impending metastatic fracture care, and patients who had treatment at an outside facility and were transferring their care. This led to a study group of 100 patients with orthopaedic trauma. The mean age was 51 years, and 51% (51 of 100) were men. The mean length of follow-up available for patients in the study was 13 months from the initial clinic visit. Patient demographics, hospital admission data, and outcome data were collected from the electronic medical records. Patients were divided into two cohorts: food-secure versus food-insecure. Patients were propensity score matched for adjusted analysis. A total of 37% of the patients in this study (37 of 100) screened positive for food insecurity during the study period. Patients with food insecurity were more likely to have a higher BMI than patients with food security (32 kg/m 2 compared with 28 kg/m 2 ; p = 0.009), and they were more likely not to have healthcare insurance or to have Medicaid (62% [23 of 37] compared with 30% [19 of 63]; p = 0.003). After propensity matching for age, gender, ethnicity, current substance use, Charleston comorbidity index, employment status, open fracture, and length of stay, food insecurity was associated with a higher percentage of superficial infections (13% [4 of 31] compared with 0% [0 of 31]; p = 0.047). There were no differences between the groups in the risk of reoperation, deep infection, and nonunion. Food insecurity is common among patients who have experienced orthopaedic trauma, and patients who have it may be at increased risk of superficial infections after surgery. Future research in this area should focus on defining these health disparities further and interventions that could address them. Level III, therapeutic study.

Comparative analysis of metacyclogenesis and infection curves in different discrete typing units of Trypanosoma cruzi

Chagas disease (CD), caused by the complex life cycle parasite Trypanosoma cruzi, is a global health concern and impacts millions globally. T. cruzi’s genetic variability is categorized into discrete typing units (DTUs). Despite their widespread presence in the Americas, a comprehensive understanding of their impact on CD is lacking. This study aims to analyze life cycle traits across life cycle stages, unraveling DTU dynamics. Metacyclogenesis curves were generated, inducing nutritional stress in epimastigotes of five DTUs (TcI (MG), TcI (DA), TcII(Y), TcIII, TcIV, and TcVI), resulting in metacyclic trypomastigotes. Infection dynamics in Vero cells from various DTUs were evaluated, exploring factors like amastigotes per cell, cell-derived trypomastigotes, and infection percentage. Statistical analyses, including ANOVA tests, identified significant differences. Varying onset times for metacyclogenesis converged on the 7th day. TcI (MG) exhibited the highest metacyclogenesis potential. TcI (DA) stood out, infecting 80% of cells within 24 h. TcI demonstrated the highest potential in both metacyclogenesis and infection among the strains assessed. Intra-DTU diversity was evident among TcI strains, contributing to a comprehensive understanding of Trypanosoma cruzi dynamics and genetic diversity.

This research investigates the prevalence of Trypanosoma species in the silver catfish (Bagrus bajad) population in Zobe Reservoir, Dutsin-Ma, Katsina State. The study aims to provide insights into the parasitic infection rates, identify prevalent Trypanosoma species, and assess its potential impacts on the health and population dynamics of silver catfish in the reservoir. A total of 108 silver catfish samples were collected from Zobe Reservoir in Dutsin-Ma, Katsina, Nigeria at bi-weekly intervals, from July-September; 2023 for the discovery of blood parasites and subjected to thorough parasitological examination. Microscopic analysis, including blood smears and tissue samples, was employed to identify and classify Trypanosoma species. Preliminary findings revealed the presence of Trypanosome infections in the silver catfish population, with a variation in prevalence rates among the sampled specimens. The study identifies specific Trypanosoma species affecting the silver catfish in Zobe Reservoir, shedding light on the diversity and distribution of these parasites in the aquatic ecosystem. The Bagrus bajad obtained according to sex indicates 29 males and 79 females were examined. Females had the highest percentage of infection, 10.12%, while males had the lowest percentage of infection, 3.45%. The results of this research contribute valuable data to the understanding of Trypanosome infections in silver catfish populations, with implications for fisheries management, conservation efforts, and the potential transmission of these parasites to other aquatic organisms. Furthermore, the study underscores the importance of continued monitoring and surveillance to assess the dynamic interactions between Trypanosomes and their fish hosts in freshwater ecosystems.

Unveiling the High Prevalence of Antibiotic Resistance and Quorum Sensing Genes in Uropathogenic <i>Escherichia coli</i>

Escherichia coli is considered one of the uropathogenic bacteria with different infection symptoms representing mild illness to acute sepsis. This study aims to detect E. coli in patients with urinary infection and investigate quorum sensing genes (lux S and motA) in multi-drug resistant isolates of E. coli. 200 urine samples were collected from patients with urinary tract infections from several hospitals in Baghdad. The antibiotics sensitivity test showed high resistance of isolates for Ampicillin (100%), Cefazolin (97%), Trimethoprim/ Sulfamethoxazole (83%), Ceftriaxone (77%), Ceftazidime and Ciprofloxacin (70% each of them), and moderate resistance of isolates for Levofloxacin (50%), Gentamicin (47%), Cefepime (40%), while low resistance Piperacillin/ Tazobactam (33%), Cefoxitin (30%), Nitrofurantoin (17%), Imipenem (10%), Ertapenem and Amikacin (7% each of them), and Tigecycline (3%). The results showed an increase percentage of infection in females was 30% in the ages 30-44 years, whereas in ages 15-29 and more than 45 years was 17%. There was a high percentage (57.11%) of resistant isolates in females which are ages 30-44 years. While the ages more than 45 years were 66.4% and ages 15-29 were 34%. While, in males, the percentage was high in ages more than 45 years (35.25%) followed by age groups 30-44 years (31.5%) and 15-29 years (31%). The prevalence percentage for luxS and motA genes in E. coli was 100%. In conclusion, E. coli isolates were multi-drug resistant due to all isolates had quorum sensing genes. Moreover, uropathogenic of E. coli in females was more frequent than in males due to the resistance of bacteria to antibiotics.

Forecasting the effect of HIV-targeted interventions on the age distribution of people with HIV in Kenya.

To provide accurate forecasts of the age distribution of people with HIV (PWH) in Kenya from 2025 to 2040. Development of a compartmental model of HIV in Kenya, calibrated to historical estimates of HIV epidemiology. We forecasted changes in population size and age distribution of new HIV infections and PWH under the status quo and under scale-up of HIV services. Without scale-up, new HIV infections were forecasted to fall from 34 000 (28 000-41 000) in 2,025 to 29 000 (15 000-57 000) in 2,040; the percentage of new infections occurring among persons over 30 increased from 33% (20-50%) to 40% (24-62%). The median age of PWH increased from 39 years (38-40) in 2025 to 43 years (39-46) in 2040, and the percentage of PWH over age 50 increased from 26% (23-29%) to 34% (26-43%). Under the full intervention scenario, new infections were forecasted to fall to 6,000 (3,000-12 000) in 2,040. The percentage of new infections occurring in people over age 30 increased to 52% (34-71%) in 2,040, and there was an additional shift in the age structure of PWH [forecasted median age of 46 (43-48) and 40% (33-47%) over age 50]. PWH in Kenya are forecasted to age over the next 15 years; improvements to the HIV care continuum are expected to contribute to the growing proportion of older PWH.

The effect of tobacco leaf extract dosage on the development of virus disease in curly chili

Curly chili is a horticultural product with high nutritional value, greatly demanded as a distinctive complement or flavoring for dishes due to its unique taste and aroma. Despite the increasing demand for chilies, production has not followed suit, mainly due to disruption caused by viruses transmitted by Bemisia tabaci and Thrips sp. This study aimed to investigate the effect of tobacco extract on the growth and development of viral diseases in curly chili. Conducted at Kwangsang Village, Jumapolo District, Karanganyar Regency, from September to December 2021, the research was designed using a completely randomized block design, with treatment doses of tobacco extract at 0 mL/L, 1 mL/L, 2 mL/L, 3 mL/L, and 4 mL/L, labeled J0, J1, J2, J3, and J4, respectively. The results indicated that the variabels, i.e. plant height, number of leaves, number of fruits, and fruit weight per plant, were significantly affected by the tobacco extract. Similarly, the disease incidence and severity of viral infection were significantly influenced by the tobacco extract application. The yield decrease in curly chili was attributed to virus infection by Bemisia tabaci and Thrips sp., which caused chlorosis and mosaic symptoms on the leaves. Although the affected plants did not die, they experienced a yield reduction. The application of tobacco extract significantly reduced the percentage of incidence and severityof virus infection on curly chili. The highest disease incidence was 35.42% (J0) and disease severity was 70.92% (J0), while the lowest disease incidence was 14.58% (J4) and disease severity was 20.58% (J4).

Detection of SARS-CoV-2 variants distributed from March 2020 to May 2022 and their effect on the infection severity in Iraqi population

New SARS-CoV-2 variants appeared in late December 2020 as Mutations accumulated in the original virus. This study aimed to provide a local database about variants of COVID-19 circulating in the Iraqi population from 2020 to 2022 and the time of emergence of new strains each month since very few local studies have documented its existence in the country. Real-time reverse transcriptase polymerase chain reaction (rRT-PCR) assays were employed to 319 collected and analyzed nasal swabs to determine whether an infection had occurred. A sophisticated diagnostic kit that sorted the distinctive mutations was implemented to evaluate the variants. Results showed Younger patients were more likely to be infected with the Alpha variant (66 patients) than older people (43 patients). Additionally, patients with wild-type infestations had more robust viral load and lower Ct threshold values, culminating in an increase in severity during infection with wild-type virus 26/32 (81.250). Meanwhile, 65/109(59.63%) of patients infected with the Alpha variant developed severe and critical illness and 51/84(60.71%)were infected with Delta or Delta plus variants. In conclusion, the Alpha variant had the highest infection percentage of 109(46.6%), followed by Delta or Delta plus variant 84(26.33%), Beta or Gamma variants 47(20.1%), Omicron variant 46(19.6%), and finally wild-type virus of 32(13.7%). February 2020 witnessed a preliminary finding of the wild-type, while the Alpha variant emerged in December 2020, Beta/Gamma variances were recognized in December 2020, Delta/Delta plus variances began in April 2021, and the Omicron variant debuted in March 2022.

Epidemic survey of Crimean-Congo hemorrhagic fever infections in the Iraqi population during 2022

The primary cause of the Crimean-Congo hemorrhagic fever (CCHF) is a virus spread by ticks. The rate of frequency of case mortality is 10–40%, which is spurred on by the CCHF virus, which also produces severe viral hemorrhagic fever outbreaks. The current study can be viewed as an epidemiological survey of CCHF infections in Iraq, with the goal of better understanding block virus transmission and preventing the risk of contracting the disease. Approximately 1370 blood samples from suspect patients were taken and separated; then, the serum was processed to remove viral RNA and tested for CCHF infection using specialized kits. Results revealed 382 (27.9%) positive cases, including 76 (19.9%) positive patients with dying compared to 306 (80.1%) who experienced cures. Findings showed a significant incidence of more than 50% of the positive cases having contact with animals and raw meat, 33% slaughtering, and 36% tick bites. Furthermore, 125 (32.7%) homemakers and 64 (16.8%) butchers had the most significant infection percentage. With 42.4% of all infections, Thiqar province had the most infected patients, followed by Misan with 9.7%, then Wasit and Babil. With 27.2% of all infections, May had the most CCHF-positive infections, followed by June and July. In conclusion, in response to the initial wave counterattack in southern Iraq, public health interventions on the veterinarian side should be implemented; these should eliminate, or at least decrease, the impact of a second wave. Illegal trading practices must be controlled if zoonotic diseases like CCHF are to stop spreading. Keywords: CCHF, Iraqi provinces, RT-PCR, tick bites, zoonotic disease.

Endo-Parasites of some Fresh Water Fish in Zobe Dam, Dutsin-Ma, Kastina State

Parasites of fish, either external or internal constitute one of the major problems to fish health and also a great concern; since they often cause disease conditions in fish which can also be transferred to man, The study is aimed to identify the endo-parasites of some fresh water fish in Zobe dam Dutsin-Ma, Kastina State. A total of 180 fish were collected from 3 different fish species. The collected Fish samples were transported in a cool bucket containing ice flex to the Biology laboratory. The fishes were weighed and placed on a dissecting tray for proper dissection in order to reveal the internal organs. They were centrifuge and the content was place on a slide for microscopic examination. The total number of the parasite based on class were 37 and varies according to the fish species. Oreochromis. niloticus and Clarias. garienpinus had the highest number of parasites with a total of 15 and 12 respectively while Bargus bayard had the lowest parasite load with 10 parasites. The highest mean fish weight recorded in this study is 0.21kg with percentage infection of 40%. The sizes of the fish species are all within the range of 9–38cm, the longest fish has size range of 1 to 38 with percentage infection of 40%. This result therefore suggests that there were various fish parasites from fish sample collected from Zobe dam and fish should be properly cooked or smoked before consumption to avoid health risk due to some these parasites.
