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 ...
Beta-lactamase detection in Staphylococcus aureus and coagulase-negative Staphylococcus isolated from bovine mastitis
(Colégio Brasileiro de Patologia Animal - CBPA, 2014-04-01)
The objectives of the study were to evaluate the presence/production of beta-lactamases by both phenotypic and genotypic methods, verify whether results are dependent of bacteria type (Staphylococcus aureus versus ...
Detection of enterotoxin and toxic shock syndrome toxin 1 genes in Staphylococcus, with emphasis on coagulase-negative staphylococci
(2007-04-30)
The detection of staphylococcal enterotoxins is decisive for the confirmation of an outbreak and for the determination of the enterotoxigenicity of strains. Since the recognition of their antigenicity, a large number of ...
Influência da mastite subclínica estafilocócica sobre as características físico-químicas e celulares do leite
(1996-01-01)
One hundred twenty-six milk samples from 63 apparently healthy cows, but positive in the California Mastitis Test were submitted to determinations of pH, acidity, density, butter-fat, total solids, non-fat solids, cryoscopic ...
Risk of peritonitis during peritoneal dialysis in carriers of Staphylococcus aureus and coagulase-negative staphylococci
(2006-11-01)
The presence of Staphylococcus aureus in the nasal cavities and pericatheter skin of peritoneal dialysis patients put them at high risk of developing peritonitis. However, it is not clear whether the presence of ...
Enterotoxin genes in coagulase-negative and coagulase-positive staphylococci isolated from bovine milk
(2013-05-01)
The objective of this study was to isolate and identify the main staphylococcal species causing bovine mastitis in 10 Brazilian dairy herds and study their capability to produce enterotoxins. Herds were selected based on ...
Detecção da produção de slime por estafilococos coagulase-negativa isolados de cateter venoso central
(2007-12-01)
Slime production is an important virulence factor of coagulase-negative Staphylococcus spp., allowing them to attach to smooth surfaces of biomaterials, and it has been associated with infections of implanted medical ...
Anti-coagulase-negative Staphylococcus activity of ethanolic extracts of propolis from two Brazilian regions and synergism with antimicrobial drugs by the E-test method
(2008-01-01)
Propolis is a natural resinous substance collected by bees from vegetal sources and its therapeutic properties have been investigated. In this work, we evaluated the inhibitory activity of ethanolic extracts of propolis ...
CARACTERIZAÇÃO DO STAPHYLOCOCCUS COAGULASE NEGATIVO ISOLADOS DE QUARTOS MAMÁRIOS DE VACAS COM MASTITE SUBCLÍNICA
(Universidade Federal de Santa Maria, 1994)
SUMMARY The present work was carried out in the region of Zona da Mata-MG, Brazil, during three months. Sixteen crossbreed cows and nineteen Holstein-Friesian cows from four herds were used. The work aimed to characterize ...
Fluoroquinolone susceptibilities to methicillin-resistant and susceptible coagulase-negative Staphylococcus isolated from eye infection
(Conselho Brasileiro de Oftalmologia, 2007-03-01)
PURPOSE: To evaluate the fluoroquinolone susceptibilities of ocular isolate coagulase-negative staphylococci (CoNS), identified at the Microbiology Laboratory - UNIFESP. DESIGN: Experimental laboratory investigation. ...
