    PREVALENCE OF BAT LYSSAVIRUS IN ASSAM
    (College of Veterinary Science, Assam Agricultural University, Khanapara, Guwahati, 2022-01) DAS, TINKU; Dutta, Jyoti B.
    Rabies is one of the oldest known tropical viral zoonotic diseases caused by Lyssavirus of the family Rhabdoviridae, affecting all warm-blooded mammals. Annually ~ 60,000 people succumb to rabies every year, out of which, India alone bears the burden of 36 per cent of the global cases. Even though most of these cases are canine-mediated, but there is no dearth of data regarding bats being one of the primary reservoirs of the virus. Several species of bat Lyssavirus have been documented and bat-transmitted rabies in humans has been regularly reported since the last century. In the present study, 34 bat samples belonging to nine species of bats were collected from eight districts of Assam, namely, Kamrup (M), Baksa, Chirang, Barpeta, Kokrajhar, Golaghat, North Lakhimpur and Dhemaji, and tested for the presence of bat Lyssavirus as per the OIE guidelines. The samples were subjected to Lateral Flow Assay (LFA), Direct Fluorescent Antibody Technique (DFA), One-step PCR. None of the samples were positive for lyssavirus indicating absence of an active lyssaviral infection in the bats during the study period.
