Abstract Staphylococcal enterotoxins (SE) are essential in human and animal infection food poisoning. This study analyzed ten genes ( sek, sel, sem, sen, seo, sep, seq, ser, ses , set ) encoding new staphylococcal enterotoxin isolated from animals humans by multiplex polymerase chain reaction (PCR). In Yogyakarta, Indonesia, samples cases (174 isolates), cattle (5 goats isolates) resulted a tot...

conclusions in our study, inducible clindamycin resistance rate was 4%; so it is necessary to conduct d-test regularly by disc diffusion for this bacterium. resistance to erythromycin, clindamycin, ciprofloxacin and gentamicin was significantly higher in mrsa isolates than methicillin susceptible staphylococcus aureus (mssa), although the methicillin resistance prevalence was low. background st...

there is a growing concern about the application of molecular methods in epidemiological studies of infectious diseases. the objective of this study was to determine the genetic stability of methicillin resistance genes in staphylococcus aureus for the evaluation of resistance strain distribution. one hundred and fifteen s. aureus isolates from patients with staphylococcal infection were collec...

conclusions methicillin-resistant staphylococcus aureus is an increasingly common cause of nosocomial infections. our results are in agreement with those of other studies reporting that a few specialized clones are responsible for most cases of mrsa nasal carriage. in this study, mrsa strains isolated from different wards of hospital were closely related when analyzed by coagulase gene typing. ...

Objective Analyze nasal colonization by oxacillin-sensitive and oxacillin-resistant Staphylococcus aureus in people with HIV/AIDS (PWHA) at days 1 and7 of hospitalization. METHOD A prospective observational study conducted in a hospital in the countryside of the state of São Paulo. Nasal swab samples were collected and analyzed through microbiological identification, at days 1 and 7 of hospit...

Background: An annual update of information about the prevalence of Staphylococcus aureus and staphylococcal enterotoxins (SEs) genes is required in every geographic area. Aims: This study was conducted to investigate the prevalence of the bacterium and type of associated enterotoxin genes in different food samples, using multiplex polymerase ...

This study assessed the in vitro activities of ceftaroline and five comparator agents against a collection of Staphylococcus aureus isolates. Ceftaroline demonstrated potent activity against community-associated methicillin-resistant S. aureus (CA-MRSA) isolates and showed bactericidal activity against vancomycin-intermediate S. aureus (VISA), vancomycin-resistant S. aureus (VRSA), heteroresist...

OBJECTIVES Staphylococcus aureus survives inside eukaryotic cells. Our objective was to assess the activity of NZ2114, a novel peptidic antibiotic, against intracellular S. aureus in comparison with established antistaphylococcal agents acting on the bacterial envelope with a distinct mechanism. METHODS The extracellular (broth) and intracellular (THP-1 monocytes) activities of NZ2114 were co...

The aim of this study was to evaluate vaccine efficacy of a commercial vaccine (Startvac, Hipra Spain) aimed at reducing intramammary infections (IMI) with Staphylococcus aureus and coagulase-negative staphylococci under field conditions. During the 21-mo duration of the study, 1,156 lactations from 809 cows were enrolled in 2 herds. During the first phase of the trial, all cows that were due t...

An epidemiological investigation was carried out on a food borne outbreak in a National Type Primary School (Chinese). The findings of the outbreak are reported. Of the 495 Chinese students (ages between 7 12 years) interviewed, 321 were exposed to one or more of the food items sold at the school canteen. The median incubation period was one hour for the outbreak. The main symptoms were related...
