Abstract

Colibacillosis is a disease caused by pathogenic Escherichia coli bacteria. Infected piglets experience weight loss, stunted growth and if not treated immediately will cause death. A 16-day-old Landrace piglet died with clinical signs of weakness and yellowish white diarrhoea for 4 days. The farmer's population was 25 pigs. Epidemiology showed morbidity of 8%, mortality of 4%, and case fatality rate of 50%. Anatomical pathology examination revealed distended intestines with bleeding and hyperaemic lungs. Bacterial culture of lung and intestinal organs showed positive results of gram-negative Escherichia coli bacteria. The results of parasitological examination of native, sedimentation and floating methods were negative for protozoan and helminth infections. Histopathology showed congestion, haemorrhage and neutrophil-dominated inflammatory cell infiltration in the intestines and lungs, while the brain, heart and liver were congested. Based on all laboratory examination results, the case pig was diagnosed with colibacillosis. Improved sanitation and biosecurity of the barn and barn environment needs to be routinely carried out.

Abstract

Free-range chickens with traditional rearing systems are susceptible to be infected with AI and ND viruses, in fact, the two viruses that are deadly to poultry can occur simultaneously. This report aims to confirm the disease diagnosis and determine the cause of death of native chickens on one farm located in Sayan Village. The native chicken sample used for this case study came from a flock of chickens showing clinical symptoms such as anorexia, swelling around the eyes, and greenish-white diarrhea. There were 17 chickens showing symptoms of illness out of a total population of 30 chickens. Within 1 week, 9 chickens were found dead of out 17 chickens that exhibited illness. The rest of the chicken's condition did not improve after being treated, so it was decided to be taken one chicken to be euthanized and necropsied. Based on the lesion that was examined macroscopically and microscopically, the characteristic lesion led to AI and ND virus infection. Confirmation of the diagnosis of the possibility of AI and ND virus infection was carried out by the microtiter technique HA test and the rapid HI test obtained positive results. In the differential diagnosis examination of the lung and small intestine samples, as well as the feces, it showed that there was no secondary infection by E. coli bacteria or the parasite Eimeria spp. Based on these findings, it can be concluded that native chickens were infected with AI and ND viruses. Therefore, farmers are advised to separate sick and healthy native chickens, vaccinate the entire population and implement biosecurity.

Abstract

Mud buffaloes (Bubalus bubalis) are livestock that play a role in the economic, social and cultural life of the people of Jembrana district, therefore aspects of buffalo health need to be considered. One of the diseases that is a problem for buffalo health and causes economic losses for farmers is trematode parasite infection, especially Fasciola spp. The aim of this study was to determine the prevalence of infection and risk factors for Fasciola spp. worms in mud buffaloes used for the makepung tradition in Jembrana district. The samples used in this study were mud buffalo feces taken from three sub-districts namely Melaya, Negara, and Mendoyo totaling 120 samples. The examination method used a modified Parfitt and Banks sedimentation test and analyzed by Chi-square test. The results showed the prevalence of Fasciola spp. worm infection in mud buffaloes was 31.7% (38/120). Chi-square test showed the risk factors of age, region and husbandry management were not associated (P>0.05) with prevalence. The data from this study can be used as information for prevention and treatment of Fasciola spp. infection in mud buffaloes in Jembrana district.
