Abstract

The role of flies in spreading disease is as a mechanical vector and a biological vector. As a mechanical vector flies carry pathogenic agents through their limbs. The fly's body has many hairs, especially on its legs. The hairs on the legs contain a kind of adhesive liquid so that small objects stick easily. Diseases transmitted by flies depend on the species. This study aims to determine the fluctuations and differences in the number of Musca spp. in a different environment on a pig farm in Denpasar City. This type of research is an observational study. The sample for this study were Musca sp. flies in two pig farms in Denpasar City. Samples were taken every day for 4 weeks at 09.00 – 14.00. Data analysis used the Wilcoxon test. The results showed that the Musca spp. found in pig farms in Ubung Kaja Village, North Denpasar, as many as 358 pigs and in Sidakarya Village, South Denpasar, as many as 981 pigs. The population of flies on pig farms in Ubung Kaja Village, North Denpasar and Sidakarya Village, South Denpasar, during 4 weeks of observation, fluctuated with the highest decrease in the 4th week and while the increase occurred in the 2nd week in North Denpasar, while in South Denpasar there was an increase in the 2nd week. up to 3. Based on the results of the study, it can be concluded that the population of flies on pig farms in Ubung Kaja Village, North Denpasar and Sidakarya Village, South Denpasar, during 4 weeks of observation, fluctuated with an increase occurring in the 3rd week in North Denpasar, while in South Denpasar there was an increase in the 2nd to 2nd week. 3. There is no difference in the number of Musca spp. in a different environment on a pig farm in Denpasar City. From these results, it can be suggested that pig farms should further improve environmental sanitation in their pens and surroundings by disposing of waste in properly managed bins and implementing good biosecurity. The research can be continued by increasing the number of places studied at different seasons so that the fluctuations of flies in the rainy and dry seasons can be determined.

Abstract

Buffaloes play an essential role in society, both as a food source and in socio-cultural aspects. One tradition involving buffaloes is Makepung in Jembrana Regency, Bali, which requires the buffaloes to be in optimal health. Gastrointestinal parasitic infections, such as Balantidium sp., can affect buffalo health and pose zoonotic risks. This study aims to determine the prevalence of Balantidium sp. infection in Makepung buffaloes and analyze the factors associated with its prevalence, including age, management practices, and geographical region. This research employs an observational method with a cross-sectional study design. A total of 120 male Makepung buffaloes from three districts in Jembrana Regency Melaya, Negara, and Mendoyo were selected using purposive sampling. Fecal samples were collected and examined using a modified sedimentation method to detect Balantidium sp. presence. Data were analyzed descriptively, and relationships between variables were tested using the Chi-square test. The results showed that the prevalence of Balantidium sp. infection in Makepung buffaloes was 45.8%. Geographical region and feed source significantly influenced infection prevalence (P<0.05), whereas age and management factors, such as housing system, and cleanliness, did not show significant effects (P>0,05). Makepung buffalo farmers are advised to improve sanitation, improve drainage, separate the enclosures, and use antiprotozoal drugs under the supervision of a veterinarian to prevent Balantidium sp. infections and resistance.

Abstract

Newcastle disease (ND) is a highly contagious viral disease of poultry with high mortality rates in velogenic strains. This paper present findings about velogenic strain of Newcastle disease in case study. The methods used in examination of animal case are observation, anatomical pathology examination, histopathology examination, TAB cultivation, serological tests, bacterial identification and parasite identification. In this case study, 28-day-old broiler chickens were obtained from a farmer in Demulih Village, Susut, Bangli. The clinical symptoms observed in the affected chickens included weakness, anorexia, difficulty breathing, greenish-white diarrhea, and torticollis. Pathological anatomical examination revealed congestion in the brain, hemorrhages in the trachea, lungs, heart, and intestines, as well as petechiae in the proventriculus. Histopathological examination showed inflammatory changes were dominated marked by mononuclear cell infiltration in the brain, trachea, lung, heart, proventriculus and intestine. Result of TAB cultivation continued with using HA test showed that virus can agglutination erythrocytes with titer 210 HA Unit. ND virus was confirmed by HI test. Based on this case study, it was concluded that the chickens were infected with ND.

Abstract

Avian Pathogenic Escherichia coli (APEC) is a pathogenic strain of E. coli that can cause systemic infections in poultry, leading to colisepticemia in chickens. This condition reduces productivity and increases financial losses for farmers. This case study aims to obtain a definitive diagnosis of the disease affecting 21-day-old broiler chickens in a farm located in Jimbaran, South Kuta District, Badung Regency, Bali. The methods used include clinical symptom observation, epidemiological analysis, anatomical pathology, histopathology, and laboratory examinations for bacteriology and parasitology. The observed symptoms included weakness, decreased appetite and water intake, dull and stiff feathers, diarrhea, and the presence of solidified yellowish-white feces around the cloaca. Epidemiological analysis revealed that the farm had approximately ±10,000 chickens, with around ±1,800 chickens exhibiting similar symptoms and approximately ±500 deaths. The morbidity rate was 18%, the mortality rate was 5%, and the case fatality rate (CFR) was 27.8%. Gross pathology examination showed the presence of fibrin in the abdominal and thoracic areas, covering the heart, liver, lungs, and kidneys. Histopathological examination revealed inflammation accompanied by heterophil inflammatory cell infiltration, necrosis, edema, hemorrhage, and congestion. Bacteriological examination was conducted by isolating bacteria using general and selective media, supported by Gram staining, catalase test, biochemical tests, and glucose fermentation tests, confirming the presence of Escherichia coli in the heart, liver, lungs, and intestines. Parasitological examination using native, sedimentation, and flotation methods on fecal samples showed no parasitic infection. The study concludes that the chickens were diagnosed with colisepticemia without any parasitic infection. Prevention measures should focus on maintaining biosecurity and farm sanitation to minimize infections caused by various pathogenic agents.

Abstract

Escherichia coli is the most common bacterial infection found in broiler chicken farms. Escherichia coli infection in poultry is generally systemic and causes bacteremia, so it is called colispticemia. Case reports were conducted to diagnose animals with protocol number 116/N/25 based on anamnesis data, clinical signs, epidemiology, anatomical pathology changes, and histopathological changes and examination in the bacteriology laboratory. 30-day-old white broiler chickens were taken from a farm owned by Mr. Rudi located in Batungsel Village, Pupuan District, Tabanan Regency. The clinical signs observed were that the chickens showed abdominal distension, were weak and did not want to eat, had slow growth compared to other chickens, diarrhea, dirt around the cloaca, shortness of breath and weight loss. After the case chicken died, a necropsy was performed, then organ samples were taken and fixed with 10% Neutral Buffered Formalin (NBF). Pathological examination of the anatomy found a layer of fibrin in the heart, liver and lungs. Tissue samples taken were brain, trachea, lungs, liver, heart, spleen, kidneys and intestines, then histopathological preparations were made with hematoxylin-eosin staining. The results of histopathological examination found infiltration of heterophilic inflammatory cells in the lungs, liver, kidneys and intestines, indicating that the case animals were infected with bacteria. Examination of samples in the bacteriology and mycology laboratories obtained positive results for Escherichia coli bacteria in heart, lung, liver and intestine specimens. It can be concluded that the case chickens were infected by E. coli bacteria or were attacked by Colisepticemia. There needs to be increased sanitation and strict biosecurity in chicken farms

Abstract

Mud Buffalo (Bubalus bubalis) is a livestock that plays a role in the economy, social and cultural community, especially in Jembrana Regency, Bali. This study aims to determine the prevalence of trematode worm infections, especially Paramphistomum sp. worms, in Mud Buffalo (Bubalus bubalis) used in the makepung tradition in Jembrana Regency. The study used an observational cross-sectional method. The sample used in this study was fresh feces with a total sample of 120 buffaloes collected from three sub-districts, namely Negara, Melaya, and Mendoyo. Sample testing was carried out at the Parasitology Laboratory, Faculty of Veterinary Medicine, Udayana University using sedimentation and Parfitt and Banks methods, then the data were analyzed using the Chi-square test. The results showed the prevalence of Paramphistomum sp. in mud buffalo was 8.33% (10/120). The Chi-square test showed that the risk factors of region, age, and maintenance management (stall system, type of stall floor, and stall cleanliness) in the statistical test had no relationship (P>0.05) with the prevalence. Meanwhile, the feed source category had a significant relationship (P<0.05). This study is can provide scientific information on the prevalence of Paramphistomum sp. infection as a basis for controlling parasitic diseases in Makepung buffalo in the Jembrana region.
