| 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 agglutination test using nine serogroups prevalent in these islands. antibodies to leptospires were detected in 164 samples giving an overall seroprevalence of (33.11%). the seroprevalence was highest among cows ( ... | 2003 | 14596541 |
