Abstract
Aim:
With the aim of revealing the epidemiological intricacies of
bluetongue (BT) in the southern part of West Bengal state, the
present study was undertaken to assess seroprevalence of BT
along with identification of the vector of the disease, i.e.,
Culicoides
midges available in the region in their breeding season with
conducive environmental factors, if any.
Materials and Methods:
A
total of 1509 (sheep-504, goat-1005) samples were collected from
three different agroclimatic zones of South Bengal
viz.
new alluvial, red laterite and coastal saline. To detect anti-BT
antibodies in the collected serum samples,
indirect-enzyme-linked immunosorbent assay (i-ELISA) was
performed.
Culicoides
midges were collected from those agro-climatic zones of South
Bengal for species identification. The meteorological
parameters,
viz.
temperature (maximum and minimum), rainfall and relative
humidity of three agro-climatic zones of South Bengal were
analyzed for the months of July to December during 2010-2013.
Results:
The overall seropositivity was 33.13% and 30.24% in sheep and
goat, respectively as assessed by i-ELISA. In South Bengal, the
predominant species of
Culicoides
found were
Culicoides schultzei,
Culicoides palpifer
and
Culicoides definitus.
Conclusion:
Since virus transmitting species of
Culicoides
midges could be detected in South Bengal, besides high
seropositivity in ruminants, the possibility of circulating BT
virus in South Bengal is quite imminent.
Keywords:
antibodies, bluetongue,
Culicoides
sp., enzyme linked immunosorbent assay, South Bengal.
