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

Newcastle Disease (ND) is a viral infection that significantly affects poultry and leads to substantial economic losses in the poultry industry. This case study aimed to achieve a definitive diagnosis of the disease in a seven-month-old free-range chicken owned by a resident of Kerta Village, Payangan Subdistrict, Gianyar Regency, Bali. The methodologies employed encompassed the collection of clinical and epidemiological data through history taking, anatomical pathology examination, histopathology, bacteriology, parasitology, and virus isolation via culture of embryonated chicken eggs, which were subsequently confirmed using hemagglutination (HA) and hemagglutination inhibition (HI) tests. Tracing and history-taking revealed that the chicken rearing system was semi-intensive. The chicken population comprised 15 chickens, of which 12 exhibited illness and 10 succumbed within eight days. The clinical signs observed included lethargy, pale bluish drooping wattle and cockscomb, periorbital edema, respiratory distress, reduced appetite and water intake, greenish diarrhea, torticollis, and limp drooping wings. Epidemiological data indicate a morbidity rate of 80%, a mortality rate of 67%, and a case fatality rate of 83%. Anatomical pathological examination through necropsy revealed multiorgan hemorrhage, pulmonary hemorrhage, petechiae in the proventriculus, and intestinal hemorrhage. Organ samples were collected for histopathological analysis with hematoxylin-eosin (HE) staining, which revealed inflammation in various organs, predominantly characterized by lymphocyte infiltration. The HA test demonstrated a high viral titer (29), and the HI test confirmed a positive ND virus infection. Bacteriological examination revealed Escherichia coli in the small intestine and cecum as part of the normal flora. Fecal examination revealed 100 eggs per gram of Capillaria spp. Based on these results, the chickens were diagnosed with a coinfection of Newcastle Disease virus and Capillaria spp. The implementation of routine vaccination programs, improved management practices, and control of poultry movement is recommended as disease prevention measures.

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

Gastrointestinal protozoan infections, including those caused by Eimeria sp., Cystoisospora sp., Entamoeba sp., and Balantidium sp., can result in significant livestock losses. This study aimed to ascertain the prevalence of gastrointestinal protozoan infections and compare the prevalence rates between suckling and weaned piglets on pig breeding farms in Gianyar Regency. A total of 216 piglet fecal samples were analyzed, comprising 87 samples from the suckling phase and 129 from the weaned phase. Gastrointestinal protozoa were identified through morphological examination, utilizing the sedimentation method for Balantidium sp. and Entamoeba sp., and the saturated salt flotation method for Coccidia examination. Differences in the prevalence of protozoan infections between suckling and weaned piglets were assessed using the Chi-Square Test with IBM SPSS Statistics. The findings indicated that the prevalence of gastrointestinal protozoan infections in piglets on breeding farms in the Gianyar Regency was 51.85% (112/216). The identified protozoa included Balantidium sp. (37.96%), Entamoeba sp. (25.92%), and Coccidia (7.87%). The prevalence of gastrointestinal protozoan infections in suckling piglets was 35.63% (31/87), whereas that in weaned piglets was 62.79% (81/129), demonstrating a significant difference (p=0,0001). There were diverse infections, with some piglets harboring more than one protozoan type. The prevalence rate of gastrointestinal protozoan infections was deemed high, with weaned piglets exhibiting greater susceptibility to infection than suckling piglets.

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

Gastrointestinal nematode infections in sows can cause physiological decline in pigs, fetal development problems, and reduced milk production. This study aimed to determine the prevalence of gastrointestinal nematode infections in sows during the gestation, lactation, and dry phases at a pig breeding farm in Gianyar District, Bali, Indonesia. This was a cross-sectional study using purposive sampling. A total of 204 fecal samples from sows in the gestation, lactation, and dry phases, collected from seven sub-districts in Gianyar Regency, were used in this study. Fecal samples were examined using sedimentation and flotation concentration methods with saturated salt to identify nematode eggs. Prevalence data were described descriptively, while the chi-square test was used to determine the relationship between the prevalence of gastrointestinal nematode infections in pregnant, lactating, and dry sows. The study reported a nematode prevalence of 46.56%, consisting of Strongyl-type worms (43.62%), Ascaris suum (2.94%), Strongyloides ransomi (2.45%), and Trichuris suis (0.49%). No significant differences were observed in prevalence between the phases (p>0.05). Co-infections were also observed in sows in this study. The prevalence of nematode infections in sows remains relatively high; therefore, it is recommended to improve management practices, particularly on farms with wet housing conditions and irregular deworming schedules.

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.

Abstract

Coccidiosis, Avian Influenza (AI), and Newcastle Disease (ND) are important diseases in broiler chickens that can cause economic losses. This case report aimed to identify the causative agents and describe the pathological changes in broiler chickens suspected of having coccidiosis accompanied by viral infection in the Ungasan District of Bali. The broiler chickens were approximately 25 days old and had bloody diarrhea. The examinations included anamnesis, epidemiological investigation, anatomical pathology, histopathology, parasitology, and bacteriology. Based on epidemiological data, morbidity was 0.7%, mortality was 0.2%, and the case fatality rate was 30% of the total population of 14,000 birds. Anatomical pathology and histopathological examinations revealed changes in almost all organs, indicating infection with the AI and/or ND virus. Necrosis, hemorrhage, inflammatory cell infiltration, and clusters of Eimeria spp. at various life stages were observed in the intestines and caecum. Qualitative and McMaster fecal examinations revealed the presence of Eimeria spp. oocysts at a rate of 132,700 oocysts/gram. Bacteriological examination identified the growth of Escherichia coli, but without any indication of secondary infection from bacteria because Escherichia coli is the normal flora of the intestine. Based on these examination results, it can be concluded that the chickens were infected with intestinal and cecal coccidiosis caused by Eimeria spp., accompanied by suspected ND and/or AI.
