Abstract

Johne’s disease (JD) or partuberculosis is a chronic granulomatous enteritis in ruminants caused by infection of Mycobacterium avium paratuberculosis subspecies (MAP). The disease has been detected serologically in Indonesia. It’s potential to spread to other herds and could create great economic losses. The objectives of current study were to detect MAP in milk and faeces of dairy cows as well as to evaluate the association between farm management factors and presence of the bacteria in dairy cows in Bogor. The sample size was calculated using the formula to detect disease with the prevalence assumed to be 5% using 95% significant level. Milk and faeces samples were taken from 62 dairy cows which were suspected as suffering from MAP infection. Detection of MAP was done by isolation in Herrold’ egg yolk medium with mycobactin J (HEYMj), acid-fast bacilli Ziehl-Neelsen staining, PCR IS900 and F57. Biochemical test to confirm M. tuberculosis presence was also conducted. Fifteen isolates of Mycobacterium sp. were found from the faeces samples but not from the corresponding milk samples. However, conventional PCR conducted on the isolate as well as the milk samples, gave negative results. Biochemical test proved that all Mycobacterium sp. isolates were not M. tuberculosis. This study indicated the prevalence of MAP in Bogor was less than 5%. These findings should be continued by observational study to achieve the comprehensive information at the cattle and herd level. Bovine Tuberculosis monitoring should be done also to protect dairy herd and food safety for the community. Key words: Johne’s disease, Mycobacterium avium subspecies paratuberculosis, Milk, Faeces

Abstract

Seropositive and isolate suspected as Mycobacterium avium subspecies paratuberculosis (MAP) was detected at dairy cows in West Java. This bacteria causes Johne’s disease (JD) and potentially becomes a new emerging disease for Indonesian dairy cows. The aim of this study was to confirm the suspected local isolate as a MAP distinctively by PCR. Reculture of MAP reference isolate, suspected local isolate done by resuspending bacteria in PBS 0.5% and inoculating it in Herrold’s egg yolk medium with mycobactin J (HEYM) and than inoculating it in 37oC for 16 weeks. The cultures grew in various time, Mycobacterium avium subspecies avium was detected in 3rd week, MAP reference was detected in 7th week, and local isolate was detected in 14th week. The confirmation test was carried out by PCR with primer F57. The PCR F57 result showed that MAP suspected isolate was not a Mycobacterium avium subspecies paratuberculosis. Key Words: Local Isolate, Mycobacterium avium Subspecies Paratuberulosis, PCR F57
