Abstract

This case report documents a fatal co-infection of Canine Parvovirus type 2 (CPV-2) and the nematode Toxocara canis in a 2.5-month-old, unvaccinated female local puppy in Denpasar, Bali. The animal presented with acute clinical signs including anorexia, vomiting, hemorrhagic diarrhea, and severe dehydration, leading to death. A comprehensive post-mortem examination was conducted, including necropsy, histopathology, Polymerase Chain Reaction (PCR), bacteriology, and parasitology. PCR analysis confirmed a CPV-2 infection, demonstrated by a 900 bp DNA amplicon. Macroscopic findings included multi-organ hemorrhages, cardiac enlargement with a blunt apex, and intestinal necrosis. Histopathology revealed widespread lymphocytic inflammation. Concurrently, parasitological examination identified a significant T. canis infection, evidenced by six adult worms in the large intestine and numerous eggs and larvae in the feces. While Escherichia coli was isolated from the intestines, no other systemic bacterial pathogens were detected. It was concluded that the synergistic pathogenicity of the CPV-2 and T. canis co-infection was the cause of death, with the parvovirus causing severe intestinal damage and immunosuppression, which was exacerbated by the parasitic burden. This case highlights the importance of integrated diagnostic approaches and underscores the critical need for regular deworming and routine vaccination in preventing such fatal disease combinations in puppies.

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.

Abstract

Malassezia spp. are part of the commensal microbiota on the skin and ears of dogs; however, under certain conditions, they can overgrow, triggering otitis externa. Systemic therapy is effective; however, its use is limited by its potential for resistance and hepatotoxic effects. This article reports a case of dextra otitis externa caused by Malassezia spp. in a 1.5-year-old male dog. On initial examination, the dog showed swelling of the right ear flap, scratching wounds, yellowish exudate, narrowing of the ear canal, as well as alopecia, erythema, and nodules on the ear flap and neck. The diagnosis was confirmed by clinical examination and cytology, which revealed the presence of Malassezia spp. The treatment consisted of ear cleaning with a 3% chlorhexidine solution (topical, q12h for 14 days), bathing with a 2% miconazole nitrate-medicated shampoo, and additional therapy with antibiotics, prednisone, chlorpheniramine maleate, and supplements. Evaluation at the 7-day post-treatment follow-up showed a marked clinical improvement. At the 25-day post-treatment follow-up, the patient recovered without recurrence. This case report confirms that topical antifungal therapy with supportive therapy is effective for the treatment of Malassezia spp. in dogs.

Abstract

Uterine torsion is a common form of dystocia in small ruminants, including goats, and can lead to failure of normal parturition. This condition is characterized by uterine twisting, which impedes the fetus's passage through the birth canal. The purpose of this paper is to describe the management of a case of uterine torsion in a goat that resulted in a fetotomy due to the fetus's excessive size. This case began with symptoms of labor difficulty (dystocia) and no labor progress. Examination revealed uterine torsion, which hindered the normal position of the fetus. Corrective measures were taken, but were unsuccessful in restoring the uterus to its optimal position. Furthermore, the excessive size of the fetus (fetal oversize) exacerbated the condition, making it impossible to perform a normal extraction. Therefore, a fetotomy was decided upon as an alternative to save the mother. The procedure was performed carefully to minimize trauma to the mother's reproductive tissues. The final results showed that the fetotomy was effective in managing this case and successfully saved the mother.

Abstract

Pig farms play an important role in the socio-cultural life of communities, but some of them are intensively managed with poor biosecurity and health management practices, as well as traditional and unhygienic husbandry practices, thereby potentially increasing the risk of health problems in livestock. Colisepticemia is a disease caused by infection with pathogenic Escherichia coli, which primarily affects piglets from the neonatal to post-weaning period. The subject of this case study was a one-month-old Landrace piglet from a smallholder farm in Taro Village, Tegallalang District, Gianyar Regency, Bali. This study aimed to determine the cause of death of the piglets based on epidemiological data, clinical examination, anatomical pathology, histopathology, bacteriology, and parasitology. Epidemiological data showed a total herd population of 455 pigs, with morbidity of 1.76%, mortality of 1.76%, and a case fatality rate (CFR) of 100%. Clinical signs observed in the piglet included anorexia, weakness, vomiting, yellowish-white diarrhea, and inability to stand. The piglet died after showing clinical signs for 16 days. Gross pathological examination revealed congestion in the brain, heart, lungs, liver, kidneys, and intestines, as well as hemorrhage in the trachea, lungs, and intestines. Histopathological examination showed that almost all organs had congestion, hemorrhage, and inflammatory cell infiltration predominantly composed of neutrophils. Bacterial isolation from the lung, heart, liver, and intestines demonstrated growth of Gram-negative Escherichia coli. Parasitological examination using direct smear, sedimentation, and flotation methods yielded negative results for protozoan and helminth infections. Based on these findings, the piglet was diagnosed with colisepticemia.

Abstract

Co-infection of Aspergillus fumigatus with Staphylococcus sp and Eimeria spp that occur in poultry farming systems has the potential to increase the severity of the disease and cause significant economic losses. This case report aims to report the results of a diagnosis of coinfection of the disease in broiler chickens at one of the farms in Benoa, South Kuta District, Badung Regency, Bali. The farm has a capacity of 16,000 heads with a closed cage system. The examination was carried out based on epidemiological fingerprints, anamnesis, clinical examination, pathology, bacteriological tests, mycology and parasitology. Clinical symptoms observed include anorexia, weakness, curled up, drowsiness, and being smaller than peers of his age (dwarf). Interview data showed that as many as 0.78% of the chicken population showed symptoms of disease (morbidity), with a mortality rate of 0.075%. About 1.05% of infected chickens die (CFR). The results of an anatomical pathology examination found a multisystemic form of aspergillosis characterized by many yellowish-white granulomas of various sizes in various organs, including the lungs, heart, proventriculus, ventricles, kidneys, spleen, and small intestine. On histopathological examination, there are special granulomatous lesions in which there are septated hyphae. Mycological tests showed the presence of Aspergillus fumigatus infection. Bacteriological tests identified the presence of Staphylococcus sp., while parasitological tests detected the presence of Eimeria spp. with a value of 12,300 oocysts per gram. Based on a series of examinations carried out, the case chickens experienced aspergillosis, staphycococosis, and coccidiosis at the same time. Coinfection of the disease needs to be a concern because it can make it difficult to diagnose and control the disease.
