Abstract

Bali cattle are native Indonesian cattle germplasm which must be preserved and cultivated. The research aims to determine the pH characteristics and number of microbes in the reticulum, omasum and abomasum of Bali cattle. The research sample was the stomach contents of the reticulum, omasum and abomasum of clinically healthy Bali cattle slaughtered at the slaughterhouse, Pesanggaran, Denpasar. Samples were taken aseptically from 30 cows. This research is observational with a cross-sectional study design. The number of bacterial and fungal colony populations was calculated using the pour plate method on nutrient agar plates and Sabouraud dextrose agar plates, respectively. The population of Enterobacteriaceae bacterial colonies was counted using the scatter method on Eosin Methylen Blue agar plates. pH measurements in cow stomach contents were carried out using pH indicator strips. The research data were analyzed descriptively. The results showed that the average pH of the reticulum, omasum and abomasum were 7,66; 6,50 and 5,26. The average total bacteria or ALTB in the reticulum, omasum and abomasum were 18,53 x 106 CFU/gr, 21,43 x 106 CFU/gr and 26,73 x 106 CFU/gr; the fungal population was 7,10 x 105 CFU/gr, 4,56 x 105 CFU/gr and 2,83 x 105 CFU/gr; Coliform counts were 60,03 x 103 CFU/gr, 57,70 x 103 CFU/gr and 61,60 x 103 CFU/gr; the number of non-Coliforms was 49,00 x 103 CFU/gr, 45,53 x 103 CFU/gr and 41,46 x 103 CFU/gr, the number of E.coli respectively 20,70 x 103 CFU/gr, 22, 83 x 103 CFU/gr and 22,86 x 103 CFU/gr.

Abstract

Pig farming in Bali plays a strategic role in meeting both animal protein demands and cultural needs, yet remains highly susceptible to viral, bacterial, and parasitic diseases. This case report documents a severe coinfection of Trichuris suis (trichuriasis) and systemic beta-hemolytic Streptococcus sp. (presumably S. suis) in a 3.5-month-old weanling piglet from Gianyar. Diagnostic methods included anamnesis, epidemiological investigation, gross pathology, histopathology, bacterial culture/identification, and parasitic examination. The piglet exhibited stunted growth, cachexia, cough, and chronic brown diarrhea. Gross and histopathological findings revealed meningoencephalitis, necrotic-edematous bronchopneumonia, and edematous-degenerative typhlitis. Bacterial isolation identified beta-hemolytic Streptococcus sp. in the brain and lungs, though neurological signs were absent. Necropsy uncovered ~4,700 T. suis in the cecum and colon, with Entamoeba sp. cysts detected in feces. This case highlights: (1) the clinicopathological manifestations of concurrent T. suis and Streptococcus sp. infections, and (2) the critical need for early detection and comprehensive diagnostics in field cases. To mitigate such coinfections, we recommend enhanced biosecurity, routine antiparasitic treatment, and periodic bacteriological surveillance.

Abstract

Canine parvovirus (CPV) is a highly infectious viral disease that poses a significant threat to puppies, often resulting in fatality if not diagnosed and treated promptly. This report investigates the cause of death of a nearly two-month-old puppy in Denpasar City. Diagnosis was confirmed through a comprehensive approach, including a thorough history, clinical examination, hematology, anatomical pathology, histopathology with hematoxylin and eosin (H&E) staining, polymerase chain reaction (PCR) for CPV, bacteriology, and parasitology examinations. Anamnesis revealed that the two puppies succumbed after exhibiting symptoms such as anorexia, vomiting, bloody diarrhea, dehydration, and cachexia, which were also observed in this puppy. Necropsy findings indicated multiorgan lesions, including hemorrhage, congestion, hyperemia, uneven organ discoloration, swelling of the heart and spleen, and worm infestation in the stomach. Histopathological analysis revealed multi-organ inflammation characterized by hemorrhage, necrosis, edema, and inflammatory cell infiltration in all organs, with lesions typical of CPV, including lymphoid follicular necrosis and intestinal Lieberkühn crypts in the intestine. PCR confirmed CPV infection, as evidenced by a 900 bp DNA band. Bacteriological examination revealed the presence of Escherichia coli and Streptococcus spp. in the intestine and Staphylococcus spp. in the spleen. Parasitological examination revealed the presence of adult worms, larvae, and eggs of Toxocara canis in the fecal sample. Based on these findings, the death of the puppy was attributed to CPV infection compounded by secondary bacterial and parasitic infections. Further testing is recommended to ascertain potential co-infection with Canine Distemper Virus.

Abstract

Pigs are among the most commonly raised livestock animals for human consumption. However, pig farming often faces significant challenges, particularly related to animal health. This case study aims to describe the anatomical pathology, histopathology, and laboratory findings to establish a definitive diagnosis of the disease that led to the death of a three-week-old piglet from Marga Village, Marga District, Tabanan Regency. Data collection included clinical observations, anamnesis, epidemiological data, and laboratory analyses, which were examined descriptively and qualitatively. The clinical signs observed in the piglet included anorexia, diarrhea, inability to stand, paddling, swelling of the limb joints, body tremors, and reddish skin lesions. Epidemiological data indicated a morbidity rate of 0.9%, a mortality rate of 0.9%, and a case fatality rate of 100%. Gross pathological findings revealed congestion and hemorrhages in the brain, lungs, heart, intestines, and kidneys. The liver and spleen appeared swollen and discolored, as did the stomach. Histopathological examination showed meningoencephalitis; hemorrhagic and edematous bronchopneumonia; intermyocardial edema; splenitis; hepatitis; hemorrhagic glomerulonephritis; gastritis; enteritis; and colitis. The dominant inflammatory cells were lymphocytes and macrophages, indicating a chronic infection. Bacteriological analysis revealed the presence of Streptococcus spp. in the brain, lungs, and liver, while parasitological examination identified Ascaris suum eggs. Based on the findings, the piglet was diagnosed with streptococcosis and ascariasis. Implementing strict biosecurity and sanitation measures is crucial in pig farming to prevent infectious diseases.
