Lineage ST62/87: The International Spread of This Potentially Invasive Lineage.

is known to be associated with a variety of infections, from pharyngitis to necrotizing fasciitis (flesh-eating disease). of the ST62/87 lineage is recognized as one of the most frequently isolated lineages of invasive infections caused by this bacterium, which may be involved in hospital outbreaks and cluster infections. Despite this, comparative genomic and phylogenomic studies have not yet been carried out for this lineage.

High frequency of increased triclosan MIC among CC5 MRSA and risk of misclassification of the SCCmec into types.

Background: Typing of staphylococcal cassette chromosome mec (SCCmec) elements is commonly used for studies on the molecular epidemiology of MRSA.

Objectives: To perform an investigation centred on uncovering the reasons for misclassification of MRSA clonal complex 5 (CC5) SCCmec type II clinical isolates in our laboratory.

Methods: MRSA isolates from CC5 were subjected to WGS and SCCmec typing.

Anti-Restriction Gene Homologs Are Highly Represented in Methicillin-Resistant and Multidrug-Resistant ST239 and ST398: Implications for Resistance Gene Acquisitions.

Multidrug resistance is commonly acquired by transferring DNA from one bacterium to another. However, the mechanisms that enhance the acquisitions of foreign genes are poorly understood, as well as the dynamics of their transmission between hosts in different environments. Here, genomic approaches were applied to evaluate the enrichment of the chromosome with resistance traits in groups of genomes with or without anti-restriction genes and to analyze some evolutionary aspects of these acquisitions.

Cellular Growth Arrest and Efflux Pumps Are Associated With Antibiotic Persisters in Induced in Biofilm-Like Environments.

(group A -GAS) is an important pathogen for humans. GAS has been associated with severe and invasive diseases. Despite the fact that these bacteria remain universally susceptible to penicillin, therapeutic failures have been reported in some GAS infections.

Peritoneopericardial diaphragmatic hernia in a healthy adult feline (): diagnosis to surgical treatment - Case report.

Peritoneopericardial diaphragmatic hernia (PPDH) is a communication between the abdomen and the pericardial sac generated by congenital anomalies triggered during diaphragmatic and pericardial development. This report aimed to present the case of an adult, mixed-breed cat, affected by PPDH, focusing on the period from diagnosis to successful surgical correction. The patient had a capricious appetite and weight loss for about four months and started, at the end of this period, a state of apathy.

Low lineage diversity and increased virulence of group C subsp. .

In some species, the population structure of pathogenic bacteria is clonal. However, the mechanisms that determine the predominance and persistence of specific bacterial lineages of group C remain poorly understood. In Brazil, a previous study revealed the predominance of two main lineages of subsp.
