Abstract

Canine Parvovirus (CPV) is a highly contagious infectious agent in dogs, with high morbidity and significant mortality rates, especially in unvaccinated animals. This study reports a case of CPV infection exacerbated by secondary bacterial pneumonia caused by Streptococcus sp. in a 10-month-old male mixed-breed dog in Denpasar, Bali. The dog exhibited clinical symptoms for four days, including bloody diarrhea, dehydration, anorexia, coughing, dyspnea, vomiting, and nasal discharge, before succumbing on the fifth day. Diagnosis was conducted through histopathological examination, Polymerase Chain Reaction (PCR), and bacterial culture. PCR results confirmed the presence of CPV with a 900 bp fragment, while bacteriological analysis identified Streptococcus sp. in lung tissue with hemolytic activity. Macroscopic analysis revealed hemorrhagic pneumonia, edematous myocarditis, and hemorrhagic enteritis, while histopathology showed inflammatory cell infiltration and tissue necrosis. Streptococcus infection worsened the dog's condition by causing severe lung inflammation, impairing respiratory function, and increasing the risk of death. The combination of CPV and secondary infection highlights the importance of vaccination in preventing CPV and the need for early detection through PCR and bacterial culture to improve prognosis and treatment effectiveness. This study emphasizes that rapid diagnosis and appropriate supportive therapy can help reduce disease severity and lower mortality rates in infected dogs.

Abstract

Paramphistomosis, caused by the trematode Paramphistomum sp., is a prevalent parasitic disease affecting Bali cattle that leads to significant health issues and productivity losses. This study evaluated the anthelmintic efficacy of albendazole (10 mg/kg BW) against Paramphistomum sp. infections in Bali cattle through fecal egg count reduction. Using a one-group pretest-posttest design, we examined 20 naturally infected Bali cattle (aged 6 months-2 years) from three locations in Bali (Bangli Regency, Badung Regency, and Denpasar City). Fecal samples were collected on day 0 (pretreatment), day 7, and day 14 post-treatment and analyzed using the Whitlock sedimentation method. The Fecal Egg Count Reduction Test (FECRT) and Paired Sample T-test were employed for data analysis. Results demonstrated a statistically significant reduction (p<0.05) in egg counts post-treatment, with FECRT reaching 87.80% by day 14. These findings indicate that albendazole is effective against Paramphistomum sp. infections in Bali cattle, supporting its use in control programs.

Abstract

African swine fever (ASF) is a highly contagious and lethal disease of pigs for which no effective vaccine is currently available. This study evaluated the pathogenicity of field African swine fever virus (ASFV) isolates from Bali and East Nusa Tenggara and assessed their potential for inactivated vaccine development using spleen-derived antigens. Based on the qPCR results, among all ASFV isolates tested, only the Bali isolate, designated B1, exhibited the highest DNA concentration, suggesting that this sample contained the highest ASFV titer. Consequently, the B1 isolate was selected and processed into chemically treated (CT-ASFV) and non-treated (NCT-ASFV) formulations. In the pathogenesis trials, pigs inoculated with NCT-ASFV developed acute ASF and died within 12 days, whereas those receiving CT-ASFV exhibited no clinical signs of ASF and showed no evidence of viral replication. In the vaccination trial, pigs immunized with CT-ASFV emulsified in Montanide™ ISA 50 V2 demonstrated survival in two out of three animals (67%) following challenge with a virulent strain, while all control animals succumbed to infection. Despite the absence of detectable humoral responses as determined by ELISA, the observed protection suggests a potential role for cell-mediated immunity. These findings indicate that the B1 isolate was highly virulent and represents a promising candidate for the development of an inactivated ASF vaccine. Further evaluation in larger-scale field trials is warranted.
