Summary: | The presence of bacterial pathogens such as <i>Brucella</i> spp., <i>Clostridium</i> spp., <i>E. coli</i>, <i>Listeria monocytogenes</i>, <i>Salmonella</i> spp., <i>Staphylococcus</i> spp., and <i>Streptococcus suis</i> not only hampers pig production but also carries significant zoonotic implications. The present study aims to conduct a comprehensive meta-analysis spanning over 13 years (2010–2023) to ascertain the prevalence of these zoonotic bacterial pathogens in Indian pig populations. The study seeks to synthesize data from diverse geographic regions within India and underscores the relevance of the One Health framework. A systematic search of electronic databases was meticulously performed. Inclusion criteria encompassed studies detailing zoonotic bacterial pathogen prevalence in pigs within India during the specified timeframe. Pertinent information including authors, publication year, geographical location, sampling techniques, sample sizes, and pathogen-positive case counts were meticulously extracted. The meta-analysis of zoonotic bacterial pathogens in Indian pig populations (2010–2023) unveiled varying prevalence rates: 9% <i>Brucella</i> spp., 22% <i>Clostridium</i> spp., 19% <i>E. coli</i>, 12% <i>Listeria monocytogenes</i>, 10% <i>Salmonella</i> spp. and <i>Streptococcus suis</i>, and 24% <i>Staphylococcus</i> spp. The application of random effects further revealed additional variability: 6% <i>Brucella</i> spp., 23% <i>Clostridium</i> spp., 24% <i>E. coli</i>, 14% <i>Listeria monocytogenes</i>, 10% <i>Salmonella</i> spp. and <i>Streptococcus suis</i>, and 35% <i>Staphylococcus</i> spp. Notably, the observed heterogeneity (I<sup>2</sup>) varied significantly from 87% to 99%. The meta-analysis findings underscore the pervasive nature of these diseases throughout India’s pig populations, accentuating the substantial impact of these pathogens on pig health and the potential for zoonotic transmission. The present study reinforces the importance of the adoption of a comprehensive One Health approach that acknowledges the intricate interplay between animal, human and environmental health.
