Abstract

This study were conducted to determine the presence of toxocariosis in beef cattle in Kasiman Subdistrict, the Regency of Bojonegoro kept under the Sekolah Peternakan Rakyat (SPR) programme. The experiment were done to identify several risk factors that may play certain roles on the degree of prevalence and infection intensity. A total of 263 head of local beef cattle with various ages were taken for faecal samples and 80 farmers were interviewed. Results of the experiment indicated the prevalence of toxocariosis was 5.32% (CI 95% = 2.61-8.04%) influenced by age and gender which showed an effect on the risk of infection. The prevalence tends to decline by age group (p <0.001): calves under 6 months of age (23.68%), and between 6-12 months of age (7.41%), 1-2 years old calves (2.04%) and the above 2 years adults (1.34%). The prevalence is higher in the males group (12.7%) compared to the females group (3.0%), (p=0.003). Logistic regression analysis concluded that age was the only affecting variable to the rate of infection with mathematical models for toxocariosis. Logit toxocariosis = -0.058 -1.098 age.

Abstract

Study on the chemical compound of painted nettle (Coleus blumei Benth) leave extract and its anthelmintic activity against chicken tapeworm were conducted. Leave of painted nettle were collected and extracted with hexane, chloroform, ethanol and water. Phytochemical analysis was carried out to determine the chemical compound of secondary metabolites. Anthelmintic activity was evaluated with an assay using chicken tapeworm in a serial microplate dilution method by determination of efective concentration 50 (EC50) using probit analysis. The result of phytochemistry analysis showed that Coleus leaves consisted of flavonoid, steroid, tannin and saponin. Three of four extracts displayed strong anthelmintic activity with the higest activity belong to chloroform extract with EC50 5 mg/ml followed by n-hexane 9 mg/ml and metanol extract 10,2 mg/ml, while water extract has a weak anthelmintic activity with 106,2 mg/ml. In general, chloroform extract proved to be a more efficient extractant of biologically active compounds than either hexane, ethanol or water extract. The promising activity displayed by a number of extracts has led to further investigation of the active compound. Unfortunately, the result of invivo assay showed that the chloroform extract treatment with dose level 25 mg/kg BW could not to reduce the number of tapeworm in chicken. It is interesting for further investigate the differences of respon between in vitro and in vivo to determine involved factors.

Abstract

Cattle and buffaloes have economic value as a source of protein and draught power. The people of Sulawesi also use buffalo in various custom and religious activities. Infections by Trematodes may disrupt livestock productivity. In Indonesia, endemic Schistosomiasis can only be found in Central Sulawesi, Indonesia (Lindu, Napu, and Bada Valleys). There is no data on the status of Trematode infection in cattle and buffalo animals in the area. The study was conducted using a cross-sectional design to measure the prevalence of Trematodosis in cattle and buffalo around the endemic areas of Schistosomiasis in July-November 2016. A total of 261 stool samples consisting of 173 cattle and 88 buffaloes from 7 villages (Anca, Bewa, Mount Gintu, Sedoa, Wangga, Watumaeta, and Wuasa Villages) were collected and stored at 2-8 °C until further analysis. The Danish Bilharziasis Laboratory method was chosen to quantify the infection by trematodes. The prevalence of the overall trematodosis of this study was 85.06%. The prevalence of Trematodosis in buffalo was higher than in cattle and differed statistically (P<0.05). The highest prevalence was Paramphistomiasis (75.48%), followed by Fascioliasis (67.05%) and Schistosomiasis japonica (30.27%). The trematodosis prevalence of each village also varied and differed statistically (P<0.05). Intensites of infection of mild, moderate, and severe infections were reported in this study. Mixed infections by two even three species of trematodes were reported in this study. Two newly endemic Schistosomiasis villages are reported, namely Bewa Village and Gunung Gintu. The results of this study are used as a basis for controlling Trematodosis in large ruminants in endemic areas especially with zoonotic potential.

Abstract

Sukabumi District is reported to date as an endemic rabies area in West Java Province. In supporting the rabies control programs, the occurrence of rabies needs to be determined to decrease the number of cases. This research aims to determine the seroprevalence of rabies and identify the risk factors associated with rabies in the district. The research was conducted in Jampang Tengah and Cisolok sub-districts with positive rabies cases on dogs and humans. The blood samples were taken from 191 selected dogs using simple random sampling. Rabies antibody titer was measured using ELISA, and the risk factor was identified using selected dogs’ data classified into intrinsic and extrinsic characteristics. Data were analyzed using the chi-square test and the calculation of the odds ratio. The results showed that the seroprevalence of rabies was 7.9% (4.9-10.9%). The average antibody titer was 0.23 EU with a minimum value of 0.03 EU and a maximum of 0.96 EU. Thus, as high as 7.8% of the population showed rabies seropositivity from the unvaccinated dogs, while among the vaccinated dogs, only 8.0% of the population with rabies protective antibody titer. The significant risk factor of rabies seroprevalence is the typology of raising area (p = 0.003), revealing that the dogs raised in the coastal area had the odds of 5.8 (1.6-21.2) higher to get the rabies seropositivity than the dogs raised in the highland area.
