Abstract

A 2-month-old male dog with suspected canine distemper virus (CDV) infection was necropsied on 27 February 2025. The dog exhibited clinical signs including anorexia, weakness, diarrhea, dyspnea, and ocular/nasal exudate. Gross and histopathological examinations were performed. Tissue samples from the brain, heart, trachea, lungs, liver, spleen, kidneys, intestines, and urinary bladder were collected during necropsy and fixed in 10% neutral buffered formalin (NBF). Histopathological sections were prepared and stained with hematoxylin and eosin (H&E). Gross pathological findings included cerebral sulcal congestion, tracheal pallor, pulmonary necrosis, blunted cardiac apex, mild hepatic hemorrhage, splenomegaly, indistinct corticomedullary junction in the kidneys, urinary bladder hemorrhage, and intestinal hemorrhage. Microscopically, lesions included encephalitis, ulcerative necrotizing tracheitis, interstitial pneumonia, hemorrhagic myocarditis, hemorrhagic hepatitis, necrotizing glomerulonephritis, necrotizing cystitis, hemorrhagic and necrotizing enteritis, and splenic lymphoid depletion. Based on the case history, clinical signs, gross pathology, and histopathological findings, the dog was definitively diagnosed with canine distemper.

Abstract

The health and performance of commercial chicken are greatly influenced by poultry house environmental management. The application of open house system with poor management may act as a predisposing factor for multipathogen colonization in poultry. This condition can lead to multiple diseases due to concurrent infections involving fungal, bacterial, and protozoal agents. This study reports a case of multipathogen-related mortality in 29-day-old broiler chicken from an open house farm in Demulih Village, Bangli Regency, Bali. Diagnostic methods include anamnesis, physical examination, epidemiological data collection, gross pathology, histopathology, bacteriology, mycology, and parasitology. Gross pathological examination revealed yellowish-white nodules in the body cavity, lungs, and kidneys; surface damage of the liver and kidneys; and hemorrhage in the cecum. Histopathology showed septate hyphae and conidiophores in the lungs as well as schizonts in the cecum, indicating fungal and protozoal infection. Mycological examination using Sabouraud Dextrose Agar and subsequent macroscopic and microscopic identification confirmed the presence of Aspergillus flavus, Aspergillus fumigatus, and Mucor spp. Bacteriological examination identified colonies of Staphylococcus sp., Acinetobacter sp., and Klebsiella sp. Parasitological analysis of fecal samples revealed Eimeria spp. oocysts at a concentration of 34,450 oocysts/gram, classified as moderate infection. The case was diagnosed as multiple disease conditions caused by concurrent multipathogen infections of fungal, bacterial, and protozoal origin. Improvements in housing management, sanitation, feed storage, strict biosecurity, and housing system considerations are required to minimize the introduction of disease-causing pathogens.
