COLISEPTICEMIA IN BROILER CHICKEN FARM IN BATUNGSEL VILLAGE, PUPUAN DISTRICT, TABANAN DISTRICT, BALI

Escherichia coli is a coliform bacterium naturally found in the intestines of mammals. However, pathogenic strains, such as Avian Pathogenic Escherichia coli (APEC), can cause systemic infections and bacteremia in poultry. Infections by Escherichia coli in broilers lead to economic losses due to decreased production and increased mortality. This case report was conducted under protocol number 1/N/24, using anamnesis, clinical signs, epidemiological data, anatomical pathology, and histopathology observations to diagnose the condition. A 28-day-old white broiler chicken was collected from a closed house farm in Batungsel Village, Pupuan District, Tabanan Regency. Observed signs included lethargy, reduced appetite, an enlarged reddish abdomen, and white diarrhea. After the chicken's death, a necropsy was performed, and organ samples were preserved in 10% Neutral Buffered Formalin (NBF). Samples of the brain, lungs, liver, heart, spleen, kidneys, intestines, bursa, and feces were analyzed in histopathology, bacteriology, and parasitology laboratories. Histopathological preparations were stained with hematoxylin and eosin for microscopic examination. Bacterial infection tests included culturing samples from the intestines, liver, lungs, and heart on general, selective-differential, and Blood Agar media, followed by primary and secondary tests. The presence of Escherichia coli and Shigella sp. was confirmed. Parasite examinations using the flotation method showed no worm eggs or coccidia. These findings confirmed that the chicken was infected with Escherichia coli and Shigella sp.To prevent such infections, maintaining clean and sanitized housing is essential. Strict biosecurity measures are crucial to prevent external bacterial contamination. With good management practices, broiler chicken health can be optimally maintained.

Avian Influenza (AI) is still endemic in Bali. This disease is very dangerous and deadly, is zoonotic in birds and humans and causes high economic losses. AI disease in poultry is caused by the Influenza virus type A. The aim of the examination is to identify the agent that caused the death of the chicken in the case to determine a definite diagnosis. The case chicken sample was a 29 day old broiler chicken from a farm in Jatiluwih Village, Tabanan Regency, Bali. Clinical symptoms of chickens include: weak chickens, shaking, shortness of breath, no appetite for eating or drinking, dull feathers, pale bluish combs, runny discharge from the beak, and white-brown watery feces. Chicken death occurred 2 days after clinical symptoms appeared. After the chicken dies, a necropsy is carried out and the samples are examined in the histopathology, virology, bacteriology and parasitology laboratories to determine the agent that caused the death. Histopathological examination showed that all organs had lesions. The results of the HA/HI test showed that the chicken was a positive case of being infected with the Avian Influenza virus. Bacterial infection testing in the media test, selective test, primary test, secondary test and confectionery test identified the presence of Staphylococcus sp bacteria. in the liver and lungs. The results of fecal examination during parasite examination using native and concentration methods did not reveal any worm eggs or protozoa. It was concluded that the case chicken was infected with Avian Influenza with secondary bacterial infection, namely Staphylococcus sp. It is recommended that breeders improve biosecurity and carry out routine and appropriate vaccinations to prevent Avian Influenza disease.

Livestock farming involves the breeding and cultivation of livestock to obtain benefits and results from these activities.

The demand for animal food from livestock (meat, eggs and milk) tends to increase over time in line with population growth, income, nutritional awareness, and improvements in education levels. Marga District, Tabanan Regency as the top three broiler chicken populations that are very close to the city center, still has great potential to be developed as a broiler chicken production site because there is still a lot of land and labor in rural areas that can be empowered. The increase and decrease in the broiler chicken population is certainly indirectly in line with the income of chicken farmers in Tabanan Regency, because it can be interpreted that the chicken population increases, income can increase and likewise if the chicken population decreases, then the income of farmers can also decrease. The purpose of this study was to determine the effect of labor, capital and length of business on broiler chicken production simultaneously and partially. This study uses quantitative research methods and statistical analysis, especially numerical analysis and statistical analysis with the aim of confirming the previously established hypothesis. This study used a sample of 63 farmers through data collection through interviews and questionnaires, with multiple linear regression methods, partial tests and simultaneous F tests. Based on the results of the SPSS calculation, the results obtained are that the variables of capital, use of labor and length of business simultaneously/together have a significant effect on the income of broiler chicken farmers. Capital, labor have a positive and significant effect partially on the income of chicken farmers, while the length of business has a positive but not significant effect on chicken Farmers

BackgroundColistin is an antibiotic used as a last-resort to treat multidrug-resistant Gram-negative bacterial infections. Colistin had been used for a long time in veterinary medicine for disease control and as a growth promoter in food-producing animals. This excessive use of colistin in food animals causes an increase in colistin resistance. This study aimed to determine molecular characteristics of colistin-resistant Escherichia coli in broiler chicken and chicken farm environments.ResultsFour hundred fifty-three cloacal and farm environment samples were collected from six different commercial chicken farms in Kelantan, Malaysia. E. coli was isolated using standard bacteriological methods, and the isolates were tested for antimicrobial susceptibility using disc diffusion and colistin minimum inhibitory concentration (MIC) by broth microdilution. Multiplex PCR was used to detect mcr genes, and DNA sequencing was used to confirm the resistance genes. Virulence gene detection, phylogroup, and multilocus sequence typing (MLST) were done to further characterize the E. coli isolates. Out of the 425 (94%; 425/453) E. coli isolated from the chicken and farm environment samples, 10.8% (48/425) isolates were carrying one or more colistin-resistance encoding genes. Of the 48 colistin-resistant isolates, 54.2% (26/48) of the mcr positive isolates were genotypically and phenotypically resistant to colistin with MIC of colistin ≥ 4 μg/ml. The most prominent mcr gene detected was mcr-1 (47.9%; 23/48), followed by mcr-8 (18.8%; 9/48), mcr-7 (14.5%; 7/48), mcr-6 (12.5%; 6/48), mcr-4 (2.1%; 1/48), mcr-5 (2.1%; 1/48), and mcr-9 (2.1%; 1/48) genes. One E. coli isolate originating from the fecal sample was found to harbor both mcr-4 and mcr-6 genes and another isolate from the drinking water sample was carrying mcr-1 and mcr-8 genes. The majority of the mcr positive isolates were categorized under phylogroup A followed by phylogroup B1. The most prevalent sequence typing (ST) was ST1771 (n = 4) followed by ST206 (n = 3). 100% of the mcr positive E. coli isolates were multidrug resistant. The most frequently detected virulence genes among mcr positive E. coli isolates were ast (38%; 18/48) followed by iss (23%; 11/48). This is the first research to report the prevalence of mcr-4, mcr-5, mcr-6, mcr-7, and mcr-8 genes in E. coli from broiler chickens and farm environments in Malaysia.ConclusionOur findings suggest that broiler chickens and broiler farm environments could be reservoirs of colistin-resistant E. coli, posing a risk to public health and food safety.

The etiology of transmissible viral proventriculitis (TVP) of broiler chickens has been discussed since its initial recognition 40 years ago. Regardless of its low direct impact on mortality rate, it leads to high economic losses in the broiler industry through reduction of food conversion, weakening of birds, and their increased susceptibility to pathogens. The aim of the present study was to examine the potential presence of TVP on the broiler chicken farms in Bosnia and Herzegovina, to characterize microscopic lesions, and to investigate the viruses implicated in etiology of TVP by PCR-based methods. In total, 143 diseased broiler chickens from 16 farms in Bosnia and Herzegovina were euthanized and subjected to necropsy and subsequent histopathology of proventriculi. A representative number of proventriculi samples (n = 50) that exhibited histopathologic changes were processed for molecular detection of chicken proventricular necrosis virus (CPNV), girovirus (GyV3), chicken anemia virus (CAV), and infectious bursal disease virus (IBDV) by PCR-based methods. In addition, samples of bursa of Fabricius (n = 39) and spleen (n = 50) were tested for IBDV. Histopathology revealed changes consistent with TVP in 39.8% (57/143) and LP (lymphocytic proventriculitis) in 2.1% (3/143) of samples. All 50 proventricular samples showed positivity to CPNV with Ct values ranging between 18 and 26. GyV3 was detected in eight samples (16%), with Ct values ranging from 11.1 to 27.5. The presence of CAV was more prominent (38%), with 19 positive broiler chickens (Ct ranging from 9.6 to 35.6). Pooled samples of spleen, bursa, and proventriculi from three farms were positive for IBDV. The obtained results represent the first documented data on TVP and the first record of CPNV and GyV3 presence in broiler farms from Bosnia and Herzegovina.

The efficacy of probiotics as alternatives to antibiotics has been defined as one of the potential strategies to prevent Salmonella spp. infection in poultry. The purpose of this study was to isolate probiotic native Lactic acid bacteria (LAB) with high compatibility to intestinal tract and prevention of Salmonella typhimurium from broiler chicken feces. Thirty-seven samples of chicken feces were collected from seven broiler chicken farms in Northern Iran. The isolates identification was carried out with morphological and biochemical tests. Agar diffusion methods were used to evaluate the antimicrobial activities against Escherichia coli and S. typhimurium. The primary probiotic characteristics such as resistance to acid and bile and adhesion to Caco-2 cells were studied. Indeed, the ability of LAB isolates to inhibit adhesion of S. typhimurium to Caco-2 cells was evaluated by exclusion, competition and displacement assays. Among 42 isolates, S08, S01 and S06 isolates which showed appropriate probiotics characteristics were selected. Isolates S08 and S01 showed to be able to adhere strongly and also S06 was adhered moderately. In the exclusion assay, the isolates S08, S01 and S06 significantly hampered adhesion of S. typhimurium cell, in the competition assay, the isolates S08, S01 showed significant level of competition activity against S. typhimurium adherence to Caco-2 cells and isolate S08 showed the greatest displacement activity. The 16S rDNA sequence revealed that S08, S01, and S06 isolates were 99.00% similar to Lactobacillus salivarius, Lactobacillus johnsonii, and Pediococcus acidilactici, respectively. The result of this study suggested that LAB isolated from broiler chicken feces could be a remarkable reservoir for identification of probiotic to inhibit the pathogenic bacteria growth.

Salmonella infection not only causes acute and chronic diseases in poultry flocks, but the infected poultry are among the most important reservoirs for a variety of Salmonella serovars frequently transmitted to humans. This study aimed to investigate the occurrence of Salmonella spp. in local poultry farms in China. Samples (n = 4255), including dead-in-shell embryos, culled day-old-hatchings and 1- to 4-week-old diseased birds, were collected for Salmonella culture from broiler chicken, meat-type duck and pigeon farms in northern China between 2014 and 2018. A total of 103 Salmonella were isolated. S.enterica serovar Enteritidis and S. Typhimurium were the most prevalent serovars, representing 53.4% and 34.9% of the isolates, respectively. Serovar diversity was the highest in ducks, with the S. Apeyeme being isolated for the first time from duck tissues. All isolates were characterized by multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE). MLST showed that all S. Enteritidis isolates shared the same sequence type (ST11), and Typhimurium showed several rare STs in addition to ST19. In comparison, PFGE showed better discrimination for S. Enteritidis and S. Typhimurium isolates, with nine distinct pulsotypes being observed. The isolates exhibited varying degrees of resistance to 15 tested antimicrobials and identified S. Enteritidis isolates (98.18%) with multiple antimicrobial resistance were a cause for concern. Our data on invasive Salmonella infection in meat-type poultry in local farms can be used to identify sources and factors associated with Salmonella spread in poultry and the associated food chain.

Prevalence of Salmonella serotypes isolated from clinical samples in chicken farms and meat in slaughterhouses in South Korea.

In the development of broiler farming in Indonesia, it is necessary to be aware of diseases that often attack livestock, namely Aspergillosis fungal infection. This case study aims to confirm the diagnosis in the death of 30-day-old broiler chickens of male sex who experienced clinical symptoms of lethargy, nasal discharge, shortness of breath, swollen eyelids, and difficulty eating for 3 days so that they were separated from the rest of the chicken population obtained at one of the farms located in Tunjuk Village, Tabanan District, Tabanan Regency, Bali. Examination of case animals included signaling, anamnesis, epidemiological data, clinical symptoms, anatomical pathology and histopathology examination, bacteriology and mycology examination, and parasitology examination. The results of the anatomical pathology examination showed congestion in the brain, petechie in the ventriculus, hemorrhage in the intestines, hemorrhage in the lungs with white nodules and white nodules in the kidneys. Histopathological examination found septa hyphae and conidiophore. In the mycological examination, the case animals identified Aspergillosis in the lung and kidney organs grown on SDA (Sabouraud Dextose Agar) media and observation under a microscope using 10% KOH dye and methylene blue. In the bacteriological examination, samples of lung and intestinal organs were cultured on general Nutrient Agar (NA) media, followed by selective Eosin Methylene Blue Agar (EMBA) media, primary tests, gram staining, biochemical tests and sugar tests until the results showed that there was a secondary infection of Klebsiella sp in the lung organ samples. The results of the examination related to parasites in the feces of case chickens by qualitative methods, namely natif (direct), sedimentation concentration, and buoyancy concentration were confirmed not to be found worm eggs or coccidia. From this case study it can be concluded that the case chicken was infected with Aspergillosis. Prevention of the spread of Aspergillosis should be done by improving farm management such as housing sanitation and good husbandry methods to prevent the risk of livestock experiencing the disease.

This study aimed to determine the anatomical pathology and histopathological, and their relationship of the ascaridiosis caused by Ascaridia galli worms infection that have been found in layer chickens after necropsy, thus facilitating the diagnosis, treatment, and prevention of ascaridiosis. This study used 1 dead chicken from the Lambaro traditional market, Ingin Jaya District, Aceh Besar Regency. The sample was taken to the Pathology Laboratory, Faculty of Veterinary Medicine, Syiah Kuala University for dissected and observed in anatomical pathology changes, then histopathological preparations were made to observe histopathological changes. Data were obtained then analyzed descriptively and presented in the form of images. The results of anatomical pathology examination in chickens infected with ascaridiosis were found the Ascaridia galli worms infestation in the intestinal lumen with moderate infestation rates and focal area of hemorrhage in the intestinal mucosa. Then, histopathological examination were found desquamation of villous epithelium, hemorrhage in the intestinal mucosa, inflammatory cell infiltration, and proliferation of cryptic cells caused by A. galli worms infection. Based on the results of the examination concluded that there is an association between anatomical and histopathological pathology findings, namely hemorrhage in the intestine.

Coccidiosis is one of the most important diseases that attack the poultry industry. This disease is an intestinal disease caused by protozoan parasites from the genus Eimeria. The aim of this case report was to establish a diagnosis of mortality in a broiler chicken aged 21 days.
