Evaluation of the antimicrobial susceptibility of methicillin-resistant Staphylococcus aureus isolated from human infections
(2006-10-05)
Multiresistant Staphylococcus aureus constitutes an important public health problem, especially in view of its possible spread in nosocomial environments. In the present work, we analyzed the susceptibility profile of 80 ...
Case report of a child with influenza and fatal community-associated methicillin-resistant Staphylococcus aureus sepsis
(Soc Brasileira Medicina Tropical, 2020-01-01)
In the present study, we report the incidence of septic shock syndrome associated with methicillin-resistant Staphylococcus aureus in a child who initially presented influenza-like illness and developed septic shock shortly ...
Molecular epidemiology of methicillin-resistant Staphylococcus aureus in the Brazilian primary health care system
(2019-03-01)
Objective: To evaluate the molecular epidemiology and to georeference Staphylococcus aureus isolated from wounds and nares of patients seen at Basic Health Units (BHUs) of a Brazilian city. Methods: Observational, ...
Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA): Molecular background, virulence, and relevance for public health
(2011-12-14)
Staphylococcus aureus and coagulase-negative Staphylococcus (CoNS) are frequently found in nosocomial environments as the main pathogen in several infections. In 1961, reports of nosocomial S. aureus resistant to methicillin, ...
Methicillin resistance in Staphylococcus aureus and coagulase-negative staphylococci: Epidemiological and molecular aspects
(Center Academic Publ Japan, 2007-09-27)
Infections caused by the genus Staphylococcus are of great importance for human health. Staphylococcus species are divided into coagulase-positive staphylococci, represented by S. aureus, a pathogen that can cause infections ...
Methicillin/Oxacillin-resistant Staphylococcus aureus as a hospital and public health threat in Brazil
(Brazilian Society of Infectious Diseases, 2010)
Methicillin-resistant Staphylococcus aureus is an established nosocomial pathogen (HA-MRSA, hospital acquired MRSA), but has recently begun to appear in the community (CA-MRSA, community acquired MRSA). The cause of ...
Regulation of the Expression of the β-Lactam Antibiotic-Resistance Determinants in Methicillin-Resistant Staphylococcus aureus (MRSA)
(American Chemical Society, 2014-02)
β-Lactam antibiotics have faced obsolescence with the emergence of methicillin-resistant Staphylococcus aureus (MRSA). A complex set of events ensues upon exposure of MRSA to these antibiotics, which culminates in proteolysis ...
Phagocytosis and killing of epidemic methicillin-resistant Staphylococcus aureus by human neutrophils and monocytes
(Brazilian Society of Infectious Diseases, 2004-02-01)
Staphylococcus aureus is a pathogen that has been associated with nosocomial infections since the preantibiotic era. Since the introduction of antibiotics in medical practice in the 1940 s, methicillin-resistant S. aureus ...
PCR-based ribotyping of Staphylococcus aureus

Short communication: Outbreak of methicillin-resistant Staphylococcus aureus (MRSA)-associated mastitis in a closed dairy herd
(2017-01-01)
Cows are probably the main source of contamination of raw milk with Staphylococcus aureus. Mammary glands with subclinical mastitis can shed large numbers of Staph. aureus in milk. Because of the risk of this pathogen to ...
