Prevalence of methicillin-resistant colonization among healthcare workers at a tertiary care hospital in northeastern Brazil.

Background: is a human pathogen of clinical importance related to a variety of infections.

Aim: The objective of this study was to analyze the molecular and epidemiological characteristics of obtained from healthcare professionals (HCP) of a hospital in southwestern Bahia, Brazil.

Methods: Samples were collected from hands, nasal cavity, and laboratory coats of 80 HCP.

and Its Membrane-Associated Lipoproteins Activate Inflammatory Genes Through the NF-κB Pathway via Toll-Like Receptor 4.

is a pathogen of cows that may cause intense inflammatory responses in the reproductive tract and interfere with bovine reproduction. The aims of this study were to evaluate the immune response of bovine blastocysts and macrophages to infection and to evaluate the invasion capacity of this microorganism in bovine blastocysts. Viable and heat-inactivated strains ATCC 49782 and CI-GOTA and their extracted membrane lipoproteins were inoculated in macrophages in the presence or absence of signaling blockers of Toll-Like Receptor (TLR) 4, TLR2/4, and Nuclear Factor KB (NF-κB).

Community-acquired methicillin-resistant Staphylococcus aureus carrying SCCmec type IV and V isolated from healthy children attending public daycares in northeastern Brazil.

Nasal colonization with methicillin-resistant Staphylococcus aureus (MRSA) have increasingly been reported in healthy communities. This study aimed to assess the rate of S. aureus in general and MRSA in particular from nasal secretion of children in daycare centers in Vitória da Conquista, Brazil.

Anti-Inflammatory Activity of the Essential Oil Citral in Experimental Infection with in a Model Air Pouch.

This study proposes to implement an alternative and effective strategy for local treatment of disease provoked by . For the analysis of possible anti-inflammatory activity of essential oil, after establishing an air pouch model, 48 male mice of Balb/c were treated, infected, and euthanized at 4 and 8 h. Thus, the total and differential white blood cells were counted in the animal's blood, and cytokines IL-1, IL-6, and TNF- were titrated using ELISA in the air pouch lavage.
