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 ...
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 ...
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 ...
Staphylococcus epidermidis and Staphylococcus haemolyticus: molecular detection of cytotoxin and enterotoxin genes
(2015)
Although opportunistic pathogens, coagulase-negative staphylococci (CoNS), including Staphylococcus epidermidis and Staphylococcus haemolyticus, have long been regarded as avirulent organisms. The role of toxins in the ...
Ocorrência de Staphylococcus sp. em água utilizada em propriedades leiteiras do Estado de São Paulo
(Universidade Federal de Minas Gerais (UFMG), Escola de Veterinária, 2003-10-01)
Com o objetivo de verificar o papel da água utilizada durante a produção do leite como via de transmissão de Staphylococcus sp., fez-se a contagem de Staphylococcus coagulase negativa e Staphylococcus aureus nas amostras ...
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 ...
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 ...
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 ...
