Predisposing factors for recurrence of hydatid cysts remained to be identified. Toll-like receptor (TLR) plays a pivotal role in bridging between acquired and innate immunity in cystic echinococcosis (CE) infection. 117 CE patients including 66 acute hydatidosis (AH; primary infection) and 51 recurrent hydatidosis (RH; chronic infection), and 117 ethnically matched healthy control (HC) were investigated from endemic regions of Iran in the period of 2015 to 2018. CE patients were definitely confirmed using histopathological and immunological assays. Genotyping of TLR2 Arg753Gln was carried out by restriction fragment length polymorphism and sequencing. The homozygous mutant-type TLR2 Gln/Gln (A/A) was represented to be associated with the occurrence of RH (P = 0.04) and conferred a 9 fold risk for susceptibility, while the heterozygous mutant-type TLR2 Arg/Gln (G/A) indicated a tendency to be associated with the occurrence of RH (P = 0.07). There was no discrepancy in the frequency of TLR2 Arg753Gln haplotypes between AH patients and HC individuals (P = 0.09). The mutant allele A was obs...
