We describe a new, efficient, sensitive, and fast single-tube multiple-PCR protocol for the identification of the most clinically significant Staphylococcus spp. and the simultaneous detection of the methicillin and mupirocin resistance loci. The protocol identifies at the species level isolates belonging to S. aureus, S. epidermidis, S. haemolyticus, S. hominis, S. lugdunensis, and S. saprophy...

A miniaturized 2-h system (RAPIDEC UR; API System, la Balme-les-Grottes, Montalieu-Vercieu, France) that uses nine enzymatic tests for the diagnosis of most uropathogens was challenged with 330 strains. With few exceptions (Citrobacter, Enterobacter, and Providencia spp., Morganella morganii, and staphylococci other than Staphylococcus saprophyticus), there were distinct patterns that allowed a...

A 5-h broth disk test, read visually for growth or no growth to determine resistance of coagulase-negative staphylococci to 1.6 micrograms of novobiocin per ml, was evaluated as a rapid test for the presumptive identification of Staphylococcus saprophyticus. The correlation with an overnight disk diffusion test was 100%.

Urinary tract infections caused by staphylococci are usually attributed to Staphylococcus epidermidis or S. saprophyticus. The case study reported here describes a persistent urinary tract infection caused by S. haemolyticus in a 38-year-old male whose infection was ultimately resolved through the use of the antibiotic trimethoprim-sulfamethoxazole.

INTRODUCTION Choosing the antimicrobial agent for initial therapy of urinary tract infection (UTI) is usually empirical and should consider the prevalence of uropathogens in different age groups and gender. OBJECTIVE To establish prevalence rates of uropathogens in community-acquired UTI in relation to age and gender. METHODS Cross-sectional study conducted in the emergency department (ED) ...

Human-pathogenic bacteria are found in a variety of niches, including free-living, zoonotic, and microbiome environments. Identifying bacterial adaptations that enable invasive disease is an important means of gaining insight into the molecular basis of pathogenesis and understanding pathogen emergence. Staphylococcus saprophyticus, a leading cause of urinary tract infections, can be found in t...

Staphylococcus aureus is a common colonizer in pigs, with methicillin-resistant S. aureus (MRSA) in particular being a potential health risk to humans. To reduce the exposure to humans, the colonization in pigs should be reduced. The aim of this study was to quantitatively compare the susceptibility of pig lineages for S. aureus colonization, and if the absence of S. aureus could be associated ...

Coagulase-negative staphylococci, particularly Staphylococcus epidermidis, are increasingly important causes of nosocomial infection. Microbiologists and clinicians no longer can afford to disregard clinical isolates of coagulase-negative staphylococci as contaminants. Accurate species identification and antimicrobial susceptibility testing, in a clinically relevant time frame, are important ai...
