Molecular mechanism of serine/threonine protein phosphatase 1 (PP1cα-PP1r7) in spermatogenesis of Toxocara canis.

Toxocariasis is one of the most important, but neglected, zoonoses, which is mainly caused by Toxocara canis. To better understand the role of serine/threonine protein phosphatase 1 (PP1) in reproductive processes of male adult T. canis, differential expression analysis was used to reveal the profiles of PP1 catalytic subunit α (PP1cα) gene Tc-stp-1 and PP1 regulatory subunit 7 (PP1r7) gene TcM-1309.

Phylogenetic analysis of Mycoplasma suis isolates based on 16S rRNA gene sequence in China.

To perform phylogenetic analysis of Mycoplasma suis isolates derived from China to define the nature of this pathogen, nearly complete of 16S rRNA genes from Chongqing, Sichuan, Henan and Guangdong isolates were amplified by PCR and sequenced. The four sequences from the blood samples in this study, with other 17 Hemoplasmas sequences and related 3 mycoplasma sequences available in the GenBank, were aligned using Clustal X (version 1.83) sequences alignment program.
