A new scheme for identification of coagulase-negative staphylococci was applied to 138 consecutive urinary isolates of coagulase-negative staphylococci. The most common species were Staphylococcus epidermidis (53%), S. hominis (12%), and S. haemolyticus (10%). S. saprophyticus comprised only 5%. The disk method for antibiotic susceptibility for all species grouped together disclosed resistance ...
coagulase-negative staphylococci (cons) are often associated with bovine mastitis and may be resistant to antimicrobial therapy. the aim of the current study was to investigate the presence of blaz (responsible for penicillin resistance) and meca (responsible for methicillin resistance) genes among 108 cons belonging to 9 different species isolated from bovine mastitis in seven dairy herds (h1-...
Mupirocin MICs and mupA presence were determined in 108 staphylococci causing prosthetic joint infection. Zero of 35 isolates (0%) of methicillin-susceptible Staphylococcus aureus, 4/15 (27%) methicillin-resistant S. aureus isolates, 3/16 (19%) methicillin-susceptible coagulase-negative staphylococci, and 11/42 (26%) methicillin-resistant coagulase-negative staphylococci were mupirocin resistan...
Lysozyme production as an aid for identification of potentially pathogenic strains of staphylococci.
Lysozyme production is a frequent property of potentially pathogenic staphylococci. In the present study, 1,186 strains of human origin, 85 strains of animal origin, and 156 strains of Staphylococcus albus (epidermidis) were tested. Of 1,114 coagulase-positive strains of human and animal origin, 1,098 were lysozyme-positive (98.5%). On the other hand, of 157 coagulase-negative strains which, ba...
AIMS The epidemiological assessment of cases of coagulase negative staphylococcal catheter related bloodstream infection. METHODS Two hundred and thirty patients with suspected catheter related bloodstream infection were evaluated over a two year period. Central venous catheters were cultured both endoluminally and extraluminally. Peripheral blood, catheter hubs, skin entry, and skin control ...
A total of 350 staphylococci isolated from various clinical sources were examined for bound and free coagulase, fermentation of mannitol, and deoxyribonuclease. The economical coagulase-mannitol-agar method of Esber and Faulcomer was found to be suitable for the detection of free coagulase and mannitol fermentation. A significant number of coagulase- and mannitol-negative staphylococci proved t...
Aerobic In clusters ● Coagulase (+): Staphylococcus aureus ● Coagulase (-): Staphylococcus lugdunensis and other coagulase-negative staphylococci In pairs/chains
Coagulase-negative staphylococci are the most frequently isolated microorganisms in early prosthetic valve endocarditis. However, they rarely cause endocarditis in native valves. The profile of patients with left-sided native valve endocarditis by coagulase-negative staphylococci is unknown, because available data are scarce and outdated. We analyzed the epidemiological, clinical, radiographic,...
An electronic surveillance network for monitoring antibiotic resistance in The Netherlands has been in operation since 1989. Seven public health laboratories participate and the system covers about 25% of all bacteriological determinations in The Netherlands. This paper reports the results of staphylococci isolated in the period 1989-1995. About 0.3% of the Staphylococcus aureus isolates in the...
