Abstract
Aim: The present study was planned with an aim to access the incidence of Peste des petits ruminants (PPR) in nomadic sheep and goat of Jammu region of Jammu and Kashmir (J&K) state of India. Materials and Methods:A total of 34 nasal swabs (13 sheep and 21 goats) samples of 13 flocks suspected for PPR infection were screened for presence of PPR virus antigen by PPR sandwich-ELISA kit. Results: The overall incidence of PPR by sandwich ELISA was observed to be 55.55%, with higher incidence in goats (66.66%) than in sheep (35.71%). Location wise incidence of PPR ranged between 33.33-100%. The overall age wise incidence of PPR was highest in young animals of 0-6 months (83.33%), followed by 6-12 months (66.66%) and lowest in adults of >12 months (31.35 %). Whereas month wise incidence of PPR was highest in the month of February. Conclusion: In nut shell it can be concluded that PPR is fairly prevalent in nomadic sheep and goats of Jammu region of J&K state with the evidences of natural transmission of PPR.
Highlights
Peste des petits ruminants (PPR) is an acute, viral disease of small ruminants caused by a Morbillivirus belonging to the family Paramyxoviridae [1]
Out of 34 animals suspected for PPR, 19 were found positive by PPR sandwich ELISA yielding an overall incidence rate of 55.88% in nomadic sheep and goats
Whereas species wise out of 21 goats and sheep tested, goats and 5 sheep were positive, yielding an overall incidence of 66.66% in goats which was higher as compared to sheep (35.71%)
Summary
Peste des petits ruminants (PPR) is an acute, viral disease of small ruminants caused by a Morbillivirus belonging to the family Paramyxoviridae [1]. Transmission of the PPR virus in nature occurs primarily through direct contact with infected animals and by inhalation of the infectious aerosol produced by combination of sneezing and coughing. Various techniques like agar gel immune diffusion test and hemagglutination were employed to diagnose the PPR in both infected [9] and experimental infected [10] animals. These techniques are easy to perform but are of little value due to their low sensitive and specificity [11,12]. A kit developed by Singh et al [11] is being used extensively for the detection of PPR virus antigen in India [13].
