Gene expression of Paracoccidioides virulence factors after interaction with macrophages and fibroblasts

Mem. Inst. Oswaldo Cruz; 116 (), 2021
BACKGROUND Paracoccidioidomycosis (PCM) is a systemic mycosis with high prevalence in Latin America that is caused by thermodimorphic fungal species of the Paracoccidioides genus. OBJECTIVES In this study, we used quantitative polymerase chain reaction (qPCR) to investigate the expression of genes rel...

Presencia de genes fimH y afa en aislamientos urinarios de Escherichia coli productora de betalactamasas de espectro extendido en Lima, Perú

RESUMEN Con el objetivo de determinar la presencia de los genes fimH y afa en aislamientos urinarios de Escherichia coli productoras de betalactamasas de espectro extendido (BLEE), se realizó un estudio descriptivo, con aislamientos del cepario del proyecto TO-06/09 del Instituto Nacional de Salud del N...

Prevalencia y caracterización genotípica de cepas de Staphylococcus aureus resistente a meticilina aisladas en un hospital regional mexicano

Rev. chil. infectol; 37 (1), 2020
Resumen Introducción: Staphylococcus aureus es uno de los patógenos con mayor prevalencia en el mundo, asociado a una alta tasa de mortalidad y un rápido desarrollo de resistencia a los antimicrobianos. A pesar de su patogenicidad, su seguimiento epidemiológico en México es escaso. Objetivo: Anali...

Detection of Bacillus anthracis and Bacillus anthracis-like spores in soil from state of Rio de Janeiro, Brazil

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Bacillus anthracis is the aetiologic agent of anthrax, a re-emerging, septicaemic, haemorrhagic and lethal disease that affects humans, domestic ruminants and wildlife. Plasmids pXO1 and pXO2 are attributes that confer pathogenicity to B. anthracis strains. This bacterium was used as biologica...

Phylogenetic Group/Subgroups Distributions, Virulence Factors, and Antimicrobial Susceptibility of Escherichia coli Strains from Urinary Tract Infections in Hatay

Abstract INTRODUCTION: Nosocomial and community acquired urinary tract infections (UTIs) are one of the most encountered infections in the world. METHODS: This study aimed to determine the antibiotic susceptibility, phylogeny, and virulence genes of 153 Escherichia coli strains isolated from UTIs. An...

Cepas chilenas de origen clínico de Vibrio cholerae no-O1, no-O139 portan los genes vcsN2, vcsC2, vcsV2, vspD, toxR2 y vopF del sistema de secreción T3SS2 presentes en una isla de patogenicidad

Rev. chil. infectol; 36 (3), 2019
Resumen Introducción. Los factores de virulencia de las cepas de Vibrio cholerae no-O1, no-O139 no son claramente conocidos. La cepa de origen septicémico NN1 Vibrio cholerae no-O1, no-O139 fue secuenciada previamente mediante la plataforma Illumina, detectándose en su genoma un fragmento de la isla ...

Detection of some virulence factors genes in Staphylococcus aureus isolated from different clinical cases

Prensa méd. argent; 105 (2), 2019
Staphylococcus aureus is one of the most important pathogenic type to humans, and the most common species responsible for a wide range of diseases such as furuncles, various abscesses, wounds abscesses resulting from surgical operations, dermatitis, soft tissue inflammation, arthritis, bones inflammation...

Molecular characteristics of methicillin-resistant Staphylococcus aureus isolates from hospital and community environments in northeastern Brazil

Braz. j. infect. dis; 23 (2), 2019
ABSTRACT This study characterized 30 MRSA isolates from intensive care unit (ICU) environment and equipment surfaces and healthy children. The SCCmec types I, IVa and V were detected in HA-MRSA isolates while CA-MRSA showed the SCCmec type IVa and V. Most isolates were classified as agr group II. All iso...

Differences in resistance profiles and virulence genes among methicillin-resistant and methicillin-susceptible Staphylococcus aureus of different lineages at a public tertiary hospital

Abstract INTRODUCTION Staphylococcus aureus is a major nosocomial pathogen that is associated with high virulence and the rapid development of drug resistance. METHODS We analyzed and compared the antimicrobial resistance, virulence profiles, and molecular epidemiology of 67 S. aureus strains, includi...
