Abstract

The aim of this research was to determine immune response of mice against vaccines derived fromcyst fluid of Taenia saginata. The study was conducted using four BALB/c mice aged 6 weeks as experimentalanimals. All experimental animals were vaccinated intra peritoneal with Taenia saginata cyst fluidemulsified in Freund’s adjuvant. Immune response in the mice was determined by detecting antibodiesusing ELISA and by the presence of lymphocytes through evaluation of blood smear. The results showedthat the cyst fluid of Taenia saginata was antigenic and capable of inducing antibody responses that weredetected by ELISA. Mean antibody titers obtained in the results of the first, second, third, and fourth ofvaccination was 3.3 units; 17.9 units; 21.2 units; and 72.1 units; respectively. Evaluation of blood smear ofvaccinated mice showed an increase in the percentage of lymphocytes after vaccination with an average66.75%, compared with the average of lymphocytes before vaccination which was 40.75%. Further researchis still required in experimental animals by vaccination followed by challenge test with Taenia saginataeggs.

Abstract

This study was performed to determine detection antibodies and isolation T. gondii infection in domestic duck in Bali. A total, 188 domestic ducks sera were examined using indirect haemaglutination test kit (IHA). Heart, brain and muscle of seropositive IHA test were used for isolation with pepsin-HCL digestion and bioassay in mice and cat. The result of these research showed that 47 (25%) ducks were found to be positive for T. gondii antibodies at the cut-off e” 1:64. The seroprevalence in male and female duck were 27,8% and 22,4% respectively, however, statistical analysis showed that the difference was not significant (P>0,05). The seroprevalence in cage and free-range duck were 18,7% and 29,2% respectively, but the difference was not statistically significant (P>0,05). The antibodies titer ranging from 1:64 to 1:2048. Also, viable T. gondii was isolated from seropositive duck by bioassay mice and cat. Most of the isolated strains were avirulent to mice. This study showed that domestic duck could have a potensial role in transmitting toxoplasmosis to human in Bali.

Abstract

The case pig originated from a farm in Tegal Suci Village, Sebatu District, Gianyar Regency, Bali. This case study review aims to establish the diagnosis of death in a 45-day-old female pig using anamnesis, epidemiological history, clinical symptoms, anatomical pathology examination, histopathology, and laboratory tests. The observed symptoms in the case pig included anorexia, weakness, and diarrhea. Necropsy results showed hemorrhaging in almost all organs of the case pig. Histopathological examination revealed lesions in the intestine, suggesting a Transmissible Gastroenteritis Virus (TGEV) infection, specifically intestinal villous atrophy. Bacteriological examination successfully isolated Escherichia coli bacteria in the lungs, liver, and heart. Fecal examination in the parasitology laboratory showed no evidence of worm eggs or protozoan infections. Based on a series of tests conducted, it can be concluded that the case pig is suspected to have been infected with TGEV and E. coli. Further testing is needed to investigate the co-infection of Transmissible Gastroenteritis Virus and E. coli in pigs to determine the appropriate treatment for severe diarrhea in pigs.

Abstract

Newcastle Disease (ND) is a highly contagious disease with a high mortality rate, showing clinical symptoms such as loss of appetite, lethargy, and diarrhea. Viral diseases are generally accompanied by a secondary infection, namely parasites. Toxicosis is a parasitic disease that causes problems and losses to chicken farms, and attacks the digestive tract in chickens. Therefore, it is necessary to conduct an examination in each laboratory to get a definitive diagnosis. In this case study, the methods of anatomical pathology examination, hispathology preparation, HA-HI examination, bacterial identification, and stool examination were used qualitatively. The results of the anatomical pathology examination found pathonomic lesions, namely ptekie in the ventricles and proventricles, hemorrhagic lungs, multifocal ulcers and ptekies in the intestines, spleen hemorrhage, renal hemoragi.

Abstract

Gastrointestinal nematode infection is a common disease affecting Bali cattle, leading to health issues and reduced productivity. The control of this disease using Albendazole can reduce nematode egg counts; however, long-term use may result in resistance. This study aims to detect Albendazole resistance against nematode infections in Bali cattle based on Egg Per Gram of Feces (EPG) values and the Fecal Egg Count Reduction Test (FECRT). The study employs a one-group pretest-posttest design with 20 Bali cattle aged 6 months to 2 years infected with gastrointestinal nematodes. Fecal samples were collected on day 0 (before treatment), day 7, and day 14 after Albendazole administration at a dose of 7.5 mg/kg body weight. Fecal samples were examined using the Whitlock method, and the data were analyzed using the FECRT and the Wilcoxon test. The results showed a significant difference (p < 0.05) in nematode egg counts before and after treatment. The overall FECRT value on day 14 reached 84.1%, indicating that Albendazole is fairly effective but with signs of resistance. The nematode species identified included Trichostrongylus sp, Ostertagia sp, and Cooperia sp, each showing different responses to treatment. Trichostrongylus sp and Ostertagia sp exhibited high sensitivity, with an FECRT value of 100% on day 14, while Cooperia sp reached only 75%, indicating resistance to Albendazole. In conclusion, Albendazole administration in Bali cattle effectively reduces gastrointestinal nematode infections, but its efficacy varies depending on the nematode species, with the highest resistance indication observed in Cooperia sp. Treatment of nematode infections in Bali cattle with Albendazole should be accompanied by anthelmintic rotation to prevent resistance, along with improved barn hygiene and feed management to reduce the risk of reinfection.

Abstract

Mud buffaloes (Bubalus bubalis) are livestock that play a role in the economic, social and cultural life of the people of Jembrana district, therefore aspects of buffalo health need to be considered. One of the diseases that is a problem for buffalo health and causes economic losses for farmers is trematode parasite infection, especially Fasciola spp. The aim of this study was to determine the prevalence of infection and risk factors for Fasciola spp. worms in mud buffaloes used for the makepung tradition in Jembrana district. The samples used in this study were mud buffalo feces taken from three sub-districts namely Melaya, Negara, and Mendoyo totaling 120 samples. The examination method used a modified Parfitt and Banks sedimentation test and analyzed by Chi-square test. The results showed the prevalence of Fasciola spp. worm infection in mud buffaloes was 31.7% (38/120). Chi-square test showed the risk factors of age, region and husbandry management were not associated (P>0.05) with prevalence. The data from this study can be used as information for prevention and treatment of Fasciola spp. infection in mud buffaloes in Jembrana district.

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.
