Differential Cytotoxic Effects of Cell-Free Supernatants of Emerging Pathogens and on Four Cell Lines Reveal Vero Cells as a Putative Candidate for Cytotoxicity Analysis.

and are recognized as emerging pathogens with zoonotic potential. Despite their increasing importance, there is a paucity of data on the cytotoxicity of these two pathogens. Therefore, in the present study, we investigated the cytotoxic potentials of the cell-free supernatants from 10 and 15 isolates for their cytotoxic effects on four different cell lines (CHO, Vero, HeLa, and MDCK).

Prevalence of bovine tuberculosis and analysis of risk factors among the dairy farms in and around Guwahati metropolitan city, India.

Bovine tuberculosis (bTB), a neglected zoonotic disease caused by Mycobacterium bovis is being reported worldwide. The present work was carried out from December 2020 to November 2021 to assess the prevalence and risk factors of bTB in peri-urban and urban dairy farms of Guwahati, Assam, India. A questionnaire was used to collect data on knowledge about bTB on 36 farms, and ten animals per farm were screened by single intradermal comparative cervical tuberculin test (SICCT) to determine the prevalence of bTB, giving a total of 360 animals.
