ABSTRACT
Toxocara canis (T. canis) is a widely prevalent zoonotic parasite that infects a wide range of mammalian hosts, including humans. We generated the full-length complementary DNA (cDNA) of the serine/threonine phosphatase gene of T. canis (Tc stp) using 5' rapid amplification of the cDNA ends. The 1192-bp sequence contained a continuous 942-nucleotide open reading frame, encoding a 313-amino-acid polypeptide. The Tc STP polypeptide shares a high level of amino-acid sequence identity with the predicted STPs of Loa loa (89%), Brugia malayi (86%), Oesophagostomum columbianum (76%), and Oesophagostomumdentatum (76%). The Tc STP contains GDXHG, GDXVDRG, GNHE motifs, which are characteristic of members of the phosphoprotein phosphatase family. Our quantitative real-time polymerase chain reaction analysis showed that the Tc STP was expressed in six different tissues in the adult male, with high-level expression in the spermary, vas deferens, and musculature, but was not expressed in the adult female, suggesting that Tc STP might be involved in spermatogenesis and mating behavior. Thus, STP might represent a potential molecular target for controlling T. canis reproduction.
