Seroprevalence of Leptospiral Infection in Rodents of DairyCattle Herds Complexes in Suburb of Mashhad-Iran

Abstract

A total of 115 rodents including 66 mole rats (Nesokia indica) and 49 house mice (Mus musculus) were<br><br>trapped from 18 commercial dairy cattle herds/farms in Mashhad suburb of Khorrassan Razavee province,<br><br>Iran. The microscopic agglutination test (MAT) with 22 live antigens were used to determine serological<br><br>responses. The seroprevalence (at a titer ≥100) was 21.73%. Serum samples showed positive reaction against<br><br>Leptospira interrogans serogroups/serovars Icterohaemorragiae icterohaemorragiae,<br><br>Grippothyphosa grippothyphosa and Sejroe hardjo and the distribution of MAT titer for serogroups/<br><br>serovars were 1:200, 1:400, 1:800 and 1:1600, respectively. The infection rate was significantly higher in<br><br>mole rats than house mice (P&lt;0.05). However, there were no significant differences among species and<br><br>different infection titers.
