A Retrospective Epidemiological Study on Bovine Haemorrhagic Septicaemia in Andhra Pradesh

Abstract

A retrospective study was conducted on Bovine Haemorrhagic Septicaemia in Andhra Pradesh state with outbreak data available over half decade with an aim to focus on factors responsible for outbreaks even after regular implementation of biannual strategic vaccination programme. Since 2017, a total number of 29 outbreaks were confirmed by Isolation and Identification, biochemical tests and Polymerase chain reaction targeting KTT72 and KTSP61 genes of Pasturella multocida type B. Our epidemiological retrospective study showed Buffaloes are more susceptible than Cattle; Mortality rate was high when first time outbreak recorded; temporally incidence was reported more in December to February months due to reverse monsoon (South west) effect in Kadapa, Kurnool, Chittoor and Nellore districts of Andhra Pradesh.
