Multilocus sequence typing analysis of human and animal Clostridium difficile isolates of various toxigenic types.
A multilocus sequence typing (MLST) scheme was developed to study the genetic relationships and population structure of 72 Clostridium difficile isolates from various hosts, geographic sources, PCR ribotypes, and toxigenic types (determined by PCR targeting tcdA and tcdB genes). MLST was performed by DNA sequence analysis of seven housekeeping genes (aroE, ddl, dutA, tpi, recA, gmk, and sodA). ...
متن کاملMultilocus 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...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Molecular analysis of Tn1546 in vanA-containing Enterococcus spp. isolated from humans and poultry.
The genes encoding the VanA type of vancomycin resistance in enterococci are located on elements related to Tn1546 (1). Heterogeneity of Tn1546 in Enterococcus faecium has been previously reported (3, 4, 6, 9, 10, 12, 14, 15, 16) and includes deletions, insertions, and mutations. In this study, Tn1546 elements from 43 vanA-containing isolates of different enterococcal species with diverse pulse...
