Aim: This study was performed to determine the genetic diversity of in sheep using nested-polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in Southern Iran.

Materials And Methods: The tissue samples of diaphragm and heart from 125 sheep were collected from the main slaughterhouses of Jahrom district in South of Fars province, Iran, between Aprils and June 2013. The DNA were extracted and analyzed by nested-PCR using specific primers for SAG2 and GRA6 loci. RFLP was used to classify strains into one of the three major lineages of .

Results: Type I was predominant in this area. The data obtained from both loci demonstrated that the frequency of each genotype was 72% Type I, 2.4% Type III, 7.2% mixed Type I and II, 16.8% mixed Type I and III, 0.8% mixed Type II and III, and 0.8% mixed Type I, II and III.

Conclusions: Although the previously published data indicated that Type II is the predominant genotype in sheep in the other parts of the world, this study showed that genotype I is the dominant genotype of in the southern Iran; however, other genotypes were detected. High diversity of genotypes including mix genotypes in lambs is of importance for the public health. These studies depict a new mapping of genotypes pattern which could be very helpful in toxoplasmosis control and prevention.
