Poor
reporting of Johne's disease (JD) in India is mainly due to
lack of diagnostic kits. Information on prevalence of JD in
domestic ruminants was extracted from literature, compiled and
presented here. Part A reports prevalence of Mycobacterium
avium subspecies paratuberculosis (MAP) in domestic
livestock in North India, using sensitive culture, ELISA kit and
PCR tests and includes the work on Johne's disease by us
(1985 - 2007), at Central Institute for Research on Goats
(CIRG). Part B includes works of other Indian workers from 1940.
Retrospective information (Part A and B), was collected from
published works and less accessible records like
thesis/dissertation, project reports and annual reports of
institutes. Published data includes serum samples submitted to
Microbiology lab (CIRG), for screening of suspected cattle (26) and
buffaloes (15), from Indian Veterinary Research Institute,
Bareilly, UP and on 69 samples from prospective cattle bulls (24,
Sahiwal and Hariana breed) and Buffalo bulls (45 Murrah breed),
earmarked for purchase from Rohtak district of Hariana from
farmer's herds. These animals were screened using indigenous
serum ELISA kit. Using Milk culture the presence of MAP in milk of
lactating goats and cows (including commercial milk and milk
products) in South UP and Punjab was 5.0-91.6%, Using milk
ELISA kit, prevalence was 37.3-54.7% and 18.1-88.4%, in goats and
dairy cattle, respectively from South UP and Punjab.
Sero-prevalence of MAP on the basis of serum ELISA kit was
8.5-65.2%, 11.1-61.9%, 17.3-42.6% and 8.6-46.7% in
goats, sheep, cattle and bulls and buffaloes, respectively in South
UP, West UP, Punjab, Rajasthan and Tamil Nadu states of country.
Prevalence on the basis of fecal culture, was 52.1-80.0%,
13,3-37.5%, 28.3-96.1%, 23.8% and a case report in goats, sheep,
cattle, blue bulls and Hog deer, respectively in South UP, Punjab
and North India. On the basis of tissues culture in South UP,
recorded presence of MAP was 22.2-65.2%, 42.3-58.9% and 48.0% in
goats, sheep and buffaloes, respectively. Using IS900 PCR, the
presence of MAP in different samples and animal species was
recorded..By using colony PCR, the DNA from different sources was
characterized as MAP. Vohra (2005), reported 37.9% prevalence of
MAP in vaginal secretions by culture from post parturient farm
goats in South UP. Singh (1998, reported 11.3% prevalence of MAP,
by fecal culture, in 12 farms of goats in North India in 1998. The
prevalence was highest in Jamunapari farm of Etawah (13.4%). Using
microscopic examination of fecal samples of farm goats, variable
prevalence has been reported by authors (10.6-82.6%) in South UP
and North India. Microscopic examination of target tissues of farm
young goats in South UP by Hajra (2003), recorded 31.0% (74)
samples positive. In fecal samples of farm sheep, 10.4% animals
were reported positive. Reported prevalence was 17.3-96.1% and
8.6-50.0% in cattle and buffaloes, respectively in North
India. Part B: prevalence in cattle and buffaloes reported by other
workers in India was 1.4-66.6% and 4.9-8.5%, respectively.
Similarly in goats and sheep, reported prevalence of Johne's
disease by other workers in India and Nepal was 2.0-14.1% and
9.7-24.0%, respectively.
