Leptospiral carrier state and seroprevalence among animal population – a cross-sectional sample survey in Andaman and Nicobar Islands
A study was conducted with the objective of assessing the leptospiral carrier state and seroprevalence among animal population of Andaman and Nicobar Islands. A total of 494 sera samples from different domestic animals and 85 samples from rats ( Rattus rattus ) were tested by microscopic agglutinati...
