Leptospirosis is a zoonosis with numerous reservoir hosts. The disease is caused by infection with various serovars of Leptospira interrogans sensu lato. This study was conducted to evaluate the seroprevalence of leptospiral infection in stray cats in Ahvaz (south-western Iran) from April 2007 to June 2008. Blood samples were collected from 102 stray cats and screened for leptospiral infection using the microscopic agglutination test (MAT). Five of the 102 cats (4.9%) were serologically positive for at least one serovar of L. interrogans. The greatest number of reactors was for L. interrogans serovar balum (five serum samples). Antibodies against more than one serovar (namely, serovars balum and australis) were detected in one sample. All positive titers were detected at 1:100 dilution. The prevalence of leptospiral infection was 5.3% and 4.4% in male and female cats, respectively. There was no significant difference in positive titer prevalence between different sexes but prevalence was significantly different between age groups (P = 0.021), as all cats with positive titers were three years of age or more. This is also the first report of infection with L. interrogans serovars balum and australis from cats in Iran.
