Peste des petits ruminants (PPR) is an acute febrile viral disease of goats and
sheep characterised by mucopurulent nasal and ocular discharges, necrotising
and erosive stomatitis, enteritis and pneumonia. The disease is endemic in India
and causes large economic losses each year due to the high rates of mortality
and morbidity in infected sheep and goats. The present study reports
observations from 58 laboratory confirmed outbreaks of PPR and provides details
of the prevalence of antibodies to PPR virus (PPRV) in 4,407 serum samples of
small ruminants. Most of the clinical specimens used for the study originated
from the northern and central parts of India. Serum samples used for the
detection of antibodies to PPRV were derived from a greater number of regions
within the country, however, these samples may not be a true representation of
the target population (unvaccinated sheep and goats over 3 months old).
Indigenously developed monoclonal antibody-based diagnostic kits were used
for the detection of PPRV antigen (sandwich enzyme-linked immunosorbent
assay [ELISA]) and antibody (competitive ELISA). Findings suggested that the
disease outbreaks were more severe in goats than sheep and that the frequency
of disease outbreaks was greater between the months of March and June
(51.7%) as compared to other periods of the year. Based on the screening of the
4,407 sera samples, the antibody prevalence of PPRV in small ruminants in India
was 33% (95% confidence interval: 32.3% to 33.7%). The prevalence of antibodies
to PPRV was noted to differ between species (i.e. sheep versus goats), age
groups and geographical regions. A greater proportion of the sheep (36.3%)
versus the goat (32.4%) population was infected with PPRV. The distribution and
prevalence of antibodies to PPRV among various age groups of animals
indicated that goats were exposed at an earlier age than the sheep, suggesting
that goats may be more susceptible to infection with PPRV. A greater number of
positive cases were observed in the southern and southwestern part of the
country (30%-60%) as compared to northern India (10%-30%). These findings
may be correlated with variations in the sheep and goat husbandry practices
within different geographic regions, the topography of different states and the
socio-economic status of individual Indian farmers.
