Virulence profile comparison between LEE-negative Shiga toxin-producing Escherichia coli (STEC) strains isolated from cattle and humans
(Elsevier Science, 2010-07)
For comparison purposes, the prevalence of 8 virulence markers was investigated, by PCR, in 153 cattle and 47 human Locus for Enterocyte Effacement (LEE)-negative Shiga toxin-producing Escherichia coli (STEC) strains ...
Phenotypic characterization and virulence-related properties of Escherichia albertii strains isolated from children with diarrhea in Brazil
(2019-03-01)
Escherichia albertii are emerging enteropathogens, whose identification is difficult, as they share biochemical characteristics and some virulence-related genes with diarrheagenic Escherichia coli (DEC). Studies on phylogeny, ...
Ribotyping and virulence markers of Yersinia pseudotuberculosis strains isolated from animals in Brazil
(Instituto Oswaldo Cruz, Ministério da Saúde, 2007-08-01)
Ribotyping and virulence markers has been used to investigate 68 Yersinia pseudotuberculosis strains of serogroups O:1a and O:3. The strains were isolated from clinical material obtained from healthy and sick animals in ...
Protective effect of a non virulent strain against infection of a highly virulent strain of Trypanosoma cruzi in a murine model
(2007)
This study was carried out to compare the infection course of Trypanosoma cruzi in the ACA inbred mouse strain inoculated with 2000 blood trypomastigotes of the Tulahuen strain and the Colombian Munanta strain. Parasitaemia ...
Assessing the diversity of the virulence potential of Escherichia coli isolated from bacteremia in São Paulo, Brazil
(Associação Brasileira de Divulgação Científica, 2013-11-01)
Most of the knowledge of the virulence determinants of extraintestinal pathogenic Escherichia coli (ExPEC) comes from studies with human strains causing urinary tract infections and neonatal meningitis and animal strains ...
Typification of virulent and low virulence Babesia bigemina clones by 18S rRNA and rap-1c
(2014-06)
The population structure of original Babesia bigemina isolates and reference strains with a defined phenotypic profile was assessed using 18S rRNA and rap-1c genes. Two reference strains, BbiS2P-c (virulent) and BbiS1A-c ...
Production of virulence factors in Candida strains isolated from patients with denture stomatitis and control individuals
(2016-05-01)
The aim of this study was to evaluate the production of virulence factors in Candida isolates from the oral cavities of 50 patients with different degrees of denture stomatitis (DS, type I, II and III) and 50 individuals ...
Mycobacterium tuberculosis Strains of the Modern Sublineage of the Beijing Family Are More Likely To Display Increased Virulence than Strains of the Ancient Sublineage
(American Society for Microbiology, 2015)
