Serovar diversity of Salmonella among poultry.

Author information

National Salmonella & Escherichia Centre, Central Research Institute, Kasauli, India.


Background & objectives:

Salmonellosis due to the consumption of contaminated poultry products is a well-known public health concern, and assessing the distribution of Salmonella serovars among poultry becomes important for better prevention and control. The objective of the present study was to assess the distribution of Salmonella serovars among poultry.


The isolates received at National Salmonella and Escherichia Centre during 2011-2016 were subjected to biochemical identification, followed by serological characterization to identify the Salmonella serovars, and the data were presented to exhibit the distribution of Salmonella serovars among poultry.


Salmonella was found to be present in poultry in all the regions included in the study. Salmonella Typhimurium, S. Gallinarum and S. Enteritidis were the most prevalent serovars accounting for 96.2 per cent of isolates. Salmonella was identified in poultry from all major egg-producing and egg-consuming States. Other serovars which were scantly identified included S. Infantis (2.7%), S. Montevideo (0.64%), S. Newport (0.26%) and S. Pullorum (0.13%).

Interpretation & conclusions:

Diverse distribution of Salmonella serovars in poultry in India, with known potential to infect human population and/or other poultry flocks, requires urgent nationwide stringent control measures.
