Dynamics of the seasonal airborne propagation of Staphylococcus aureus in academic dental clinics

J. appl. oral sci; 26 (), 2018
Abstract Objective Staphylococcus aureus strains can be disseminated during dental treatments and occasionally lead to the contamination and infection of patients and dentists, which is an important public health problem. The dynamics of the airborne propagation and the genetic diversity of S. aureus is...

Participation of the arcRACME protein in self-activation of the arc operon located in the arginine catabolism mobile element in pandemic clone USA300

Mem. Inst. Oswaldo Cruz; 112 (7), 2017
ABSTRACT Staphylococcus aureus pandemic clone USA300 has, in addition to its constitutive arginine catabolism (arc) gene cluster, an arginine catabolism mobile element (ACME) carrying another such cluster, which gives this clone advantages in colonisation and infection. Gene arcR, which encodes an oxygen...

Frequência de genes codificadores de toxinas em Staphylococcus aureus isolados de leite de tanques expansão comunitários

Pesqui. vet. bras; 37 (7), 2017
A capacidade de produção de toxinas pelo Staphylococcus aureus no leite e produtos derivados está relacionado com surtos de intoxicação alimentar. Objetivou-se nesta pesquisa, estudar a ocorrência de genes que codificam para enterotoxinas estafilocócicas (sea, seb, sed, seg, seh e sei) e toxinas ...

Portación nasal deStaphylococcus aureus y sus perfiles de resistencia a antibióticos en niños que viven en zonas de gran altitud del sudoeste de China

Arch. argent. pediatr; 115 (3), 2017
Antecedentes/Objetivo. Describir el perfil epidemiológico de la portación nasal de cepas de Staphylococcus aureus (S. aureus), su resistencia a antibióticos y la presencia de los genes de leucocidina de Panton-Valentine (LPV) y mecA en niños en edad escolar que viven en zonas de gran altitud del sudo...

Local circulating clones of Staphylococcus aureus in Ecuador

Braz. j. infect. dis; 20 (6), 2016
ABSTRACT The spread of pandemic Staphylococcus aureus clones, mainly methicillin-resistant S. aureus (MRSA), must be kept under surveillance to assemble an accurate, local epidemiological analysis. In Ecuador, the prevalence of the USA300 Latin American variant clone (USA300-LV) is well known; however, t...

Staphylococcus aureus adquiridos en la comunidad: caracterización clínica, fenotípica y genotípica de aislados en niños paraguayos

Rev. chil. infectol; 33 (6), 2016
Introduction: The prevalence of Staphylococcus aureus in the community has increased, being the pediatric population the most affected. This fact highlights the need for epidemiological surveillance. Aim: To characterize clinical, phenotypic and genotypic isolates of S. aureus children’s samples wi...

Relationship between super antigenicity, antimicrobial resistance and origin of Staphylococcus aureus isolated

Colomb. med; 47 (1), 2016
Introduction: Staphylococcus aureus is a pathogen that causes food poisoning as well as hospital and community acquired infections. Objective: Establish the profile of superantigen genes among hospital isolates in relation to clinical specimen type, susceptibility to antibiotics and hospital or community...

Resistência aos antimicrobianos e análise da diversidade genética de Staphylococcus aureus por PCR-RAPD

O objetivo deste trabalho foi analisar a sensibilidade antimicrobiana in vitro de cepas de Staphylococcus aureusisoladas de tetos de vacas e mãos de retireiros, além de verificar o polimorfismo entre elas pela técnica de PCR-RAPD. Os testes foram realizados pela técnica de difusão em discos e, após...

A genetic study of a Staphylococus aureus plasmid involving cure and transference

Säo Paulo med. j; 114 (1), 1996
High frequency transfer and elimination of drug resistance may indicate an extrachromosomal inheritance of genetic determinants. This study shows the cure and transfer of a small plasmid and tetracycline resistance in Staphylococcus aureus 1030 (55) Tetr strains. Several methods are available for plasmid...
