Trichomonas vaginalis: identification of a triacylglycerol acylhydrolase.

This work describes the identification of a triacylglycerol lipase named TVLip directly onto blood-LB-agar plates by hemolytic screening of a Trichomonas vaginalis cDNA expression library. Sharing significant similarity in the primary sequence with other lipases, the theoretical 3D structure of the TVLip was resolved. The structure reveals the predictive conserved characteristics of other lipases from EC3.

Trichomonas vaginalis: intrastrain polymorphisms within the ribosomal intergenic spacer do not correlate with clinical presentation.

Trichomoniasis presents a broad spectrum of clinical patterns ranging from asymptomatic to severe vaginitis and cervicitis. Despite its importance, very little is known about the genetic relatedness of its causative agent, Trichomonas vaginalis, and the clinical phenotypes. To address this question, analysis of restriction length polymorphism (RFLP) within the intergenic spacer of the ribosomal DNA (IGS) from 60 clinically defined isolates of T.
