Oxacillin Resistance of Staphylococcus aureus Isolated from the University Hospital of Botucatu Medical School in Brazil
(Karger, 2010-01-01)
Background: Oxacillin is the main drug used for the treatment of Staphylococcus aureus infections. However, resistance of S. aureus to oxacillin has become a major problem over recent decades. The aim of this study was to ...
Oxacillin Resistance and Antimicrobial Susceptibility Profile of Staphylococcus saprophyticus and Other Staphylococci Isolated from Patients with Urinary Tract Infection
(Karger, 2012-01-01)
Background: Staphylococcus saprophyticus is the second most frequent community-acquired causative agent of urinary tract infection (UTI). The objective of this study was to evaluate the susceptibility profile and resistance ...
Detection of oxacillin resistance in Staphylococcus aureus isolated from the neonatal and pediatric units of a brazilian teaching hospital
(2009)
To determine, by phenotypic and genotypic methods, oxacillin susceptibility in Staphylococcus aureus strains isolated from pediatric and neonatal intensive care unit patients seen at the University Hospital of the Botucatu ...
Methods for detection of oxacillin resistance among coagulase-negative staphylococci recovered from patients with bloodstream infections at the University Hospital in Brazil
(2012)
Coagulase-negative staphylococci (CoNS) are among the main causative agents of nosocomial infections, and multi-resistant strains has become a major issue over the past decades. The objectives of this study are to determine ...
Evaluation of reference values for phenotypic tests to detect oxacillin resistance in coagulase-negative staphylococci
(2018-04-01)
Aim: To evaluate the adequacy of the disc-diffusion test and E-test® compared with detection of mecA for coagulase-negative staphylococci isolated from blood cultures, nasal swabs and wounds. Results: Agreement between all ...
New antimicrobial combinations: substituted chalcones- oxacillin against methicillin resistant Staphylococcus aureus
(Sociedade Brasileira de Microbiologia, 2011-06)
Staphylococcus aureus, the most virulent Staphylococcus species, is also the prevalent pathogen isolated from hospitalized patients and the second most common from patients in outpatient settings. In general, bacteria have ...
Antimicrobial resistance and persistence of Staphylococcus epidermidis clones in a Brazilian university hospital
(2013-10-01)
Oxacillin is an alternative for the treatment of Staphylococcus spp. infections; however, resistance to this drug has become a major problem over recent decades. The main objective of this study was to epidemiologically ...
Detection of the agr System and Resistance to Antimicrobials in Biofilm-Producing S. epidermidis
(2020-12-03)
The ability of Staphylococcus epidermidis to produce virulence factors, such as biofilm, added to its increased resistance to antimicrobials can cause infections that are difficult to treat. Many staphylococcal virulence ...
Swine as reservoirs of zoonotic borderline oxacillin-resistant Staphylococcus aureus ST398
(2021-12-01)
Methicillin resistance mediated by the mecA gene in Staphylococcus aureus, also known as “true MRSA”, is typically associated with high oxacillin MIC values (≥8 mg/L). Because non-mecA-mediated oxacillin resistant S. aureus ...
