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-...

Vital staining of Mycoplasma colonies was attempted because other dye visualization techniques kill the organisms and preclude reisolation for further studies. The lipophilic amphoteric dye Chlorazol Black E (CBE) was the most successful of 14 vital dyes tested on Mycoplasma hominis, M. pharyngis, M. fermentans, M. arthritidis, M. salivarium, M. pneumoniae, and L-forms of Staphylococcus aureus ...

. From coastal ecosystems of the Dead Sea (vertical steep gorge around of the Dead Sea, clay-salt plain and a black highly mineralized muds) Bacillus licheniformis, B.subtilis subsp. subtilis, Bacillus sp., Staphylococcus hominis strains have been isolated. All strains grew at 0-10 % of NaCl in medium, in a range of 20-50°С. Resistance to UV has been revealed in all the investigated bacteria. L...

PURPOSE The National Institutes of Health classification of prostatitis reported the proportion of chronic bacterial prostatitis, especially category II, at 3% to 10%. Because of the polymerase chain reaction (PCR) diagnosis technique, chronic prostatitis syndrome (CPS) with a known bacterial origin has increased recently. In this study, we evaluated the proportion of chronic bacterial prostati...

In this study, 217 edible nut samples have been investigated regarding Staphylococcus aureus and coagulase-negative staphylococci (CNS). S. aureus was isolated in 26 (11.98%) samples, whereas CNS were isolated in 98 (45.16%) samples. Number of samples for different isolated CNS species was as follows: S. arlettae 19 (8.76%), S. saprophyticus 14 (6.45%), S. xylosus 12 (5.53%), S. epidermis 11 (5...

OBJECTIVES To determine in vitro susceptibilities of a large series of speciated coagulase-negative staphylococci (CNS) against three new antibiotics, linezolid, quinupristin/dalfopristin and telithromycin. METHODS Susceptibilities to three new antibiotics and oxacillin, vancomycin, clindamycin and erythromycin were determined by the agar dilution method, as described by the NCCLS. RESULTS ...

MICs of pefloxacin and nine antistaphylococcal drugs were determined for 200 isolates of Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus haemolyticus, Staphylococcus hominis, and Staphylococcus saprophyticus. All the strains were susceptible to pefloxacin, vancomycin, and rifampin. Oxacillin-resistant strains were uniformly resistant to cephalothin and were more likely to be r...

Staphylococcal enterotoxins have been shown to promote lymphoma-associated immune dysregulation. This study examined changes in the skin microbiome of parapsoriasis compared with intact skin. Swab microbiome specimens were taken of the parapsoriasis lesions of 13 patients. Control samples were taken from contralateral healthy sides of the body. Microbiotas were characterized by sequencing the V...
