Spatial distribution of coagulase-negative staphylococci (CNS) in parts ofBundelkhand: Relevance to the high incidence of subclinical mastitis

Abstract

Coagulase-negative Staphylococcihave emerged as a major group of pathogens in mastitis of dairy animals. Thepresent work was performed to investigate the spatial distribution of milk-associated CNS pathogens in parts of Bundelkhandand to understand its relevance to the incidence of subclinical mastitis during the period 2016-2019. Etablished methods forculture and characterization of bacterial were used confirmation of HighStaphTM kit for identification of Staphylococci.Predominance of coagulase-negative Staphylococci among all bacterial pathogens in this region along with species distributionhas been established. On considering CNS as a single group of pathogens, the CNS prevalence was found 39.20%, 38.40%,22.40%, respectively for Jhansi, Jalaun, and Lalitpur. Since CNS distribution and subclinical mastitis incidences have highvariability for different agro-climatic regions, this study will supplement the course of treatment and management of subclinical mastitis (SCM) in the region through the development of understanding on causes and relationships of disease.
