Genetic characterization of Trichomonas vaginalis isolates by use of multilocus sequence typing.

TITLE: Genetic Characterization of Trichomonas vaginalis Isolates using Multilocus Sequence

Trichomonas vaginalis metronidazole resistance is associated with single nucleotide polymorphisms in the nitroreductase genes ntr4Tv and ntr6Tv.

Metronidazole resistance in the sexually transmitted parasite Trichomonas vaginalis is a problematic public health issue. We have identified single nucleotide polymorphisms (SNPs) in two nitroreductase genes (ntr4Tv and ntr6Tv) associated with resistance. These SNPs were associated with one of two distinct T. vaginalis populations identified by multilocus sequence typing, yet one SNP (ntr6Tv A2...

Multilocus Sequence Typing of the Clinical Isolates of Salmonella Enterica Serovar Typhimurium in Tehran Hospitals

Background: Salmonella enterica serovar Typhimurium is one of the most important serovars of Salmonella enterica and is associated with human salmonellosis worldwide. Many epidemiological studies have focused on the characteristics of Salmonella Typhimurium in many countries as well as in Asia. This study was conducted to investigate the genetic characteristics of Salmonella Typhimurium using m...

Multilocus Sequence Typing (MLST) of Enterococcus faecalis clinical isolates in Ilam, Iran

Introduction: The Enterococcus faecalis (E. faecalis) is the one of the pathogenic bacteria that become famous and considerable in the recent years. Here we tried to do typing the E. faecalis isolates to provide advantageous information that can help us to understand epidemiological communication between the E. faecalis isolates. Materials and methods: One hundred  E. faecalis were isolated fr...

Multilocus Sequence Typing for Molecular Epidemiology of Stenotrophomonas maltophilia Clinical and Environmental Isolates from a Tertiary Hospital in West of Iran

Background: Stenotrophomonas maltophilia is an opportunistic bacterium, contributing to different hospital-acquired infections and can be acquired from different hospital setting sources. Epidemiological study of S. maltophilia in the hospital also demonstrates the intrahospital distribution of certain strains of bacteria in healthcare facilities. The aim of the current study was to identify th...
