چکیده مقاله:
Neospora caninum is an obligate intracellular protozoan parasite of the phyllum Apicomplexa which is considered as one of the major factors in abortion in dairy cows. Serologic evidence suggests that humans are exposed to the organism. The aim of the present survey was to evaluate serological prevalence of Neospora caninum in wild rats in Ahvaz district. Blood samples were collected from 150 adult wild rats. Antibody against Neospora caninum was detected in serum using Neospora agglutination test. Among 150 samples, nine cases (6%) showed infection in 1:20 to 1:320 dilutions. The highest titer of antibody was detected in 1:20 dilution (6%) and the lowest titer was in 1:320 (0.6%) dilution. The antibody titers were as follows: 1:20 (n=9), 1:40 (n=8), 1:80 (n=6), 1:160 (n=2) and 1:320 (n=1). Posititve samples of 6.67%, 3.33% and 10% for N. caninum were identified in north and west, east and center, and south of Ahvaz, respectively. This difference was not statistically (P<0.05) significant and odds ratio was similar in all districts. The seroprevalence was 6.02% in male and 5.97% in female rats which was not statistically (P<0.05). The present study showed that relatively moderate percentage (6%) of rats was infected by Neospora caninum in Ahvaz district. Wild rats can play an important role in the transmission of this parasite to other animals.
