Rapid identification of Staphylococcus aureus by using lysostaphin sensitivity.
Lysostaphin sensitivity was evaluated as a rapid screening test to differentiate Staphylococcus aureus from other species of staphylococci and micrococci. A total of 168 strains of staphylococci, 108 of which were S. aureus, were cultured overnight in brain infusion broth. Gram stains were peformed before and after a 1:10 dilution of the culture was exposed to 2 micrograms of lysostaphin per ml...

A rapid screening test for Staphylococcus aureus that utilizes lysostaphin sensitivity was found to be reliable for organisms cultured in 12 different commercial blood culture media.
متن کاملSusceptibility of coagulase-negative staphylococci to lysostaphin and other antibiotics.
In general, coagulase-negative staphylococci were found to be relatively less susceptible to the lytic action of lysostaphin than coagulase-positive staphylococci. To achieve, arbitrarily, a lysis greater than 75%, it was necessary to use an increased concentration of enzyme or a longer incubation period than that usually required with coagulase-positive strains. For the most part, the cultures...
متن کاملClassification of staphylococci by penicillin lysis.
It has been recognized for some time that staphylococci may be divided into those which do and those which do not produce a penicillinase (Hobby & Dawson, 1944; Spink, Ferris & Vivino, 1944; Kirby, 1945a, b) . Also, staphylococci are often tested for their penicillin sensitivity (tolerance) and classified as ‘sensitive’ or ‘insensitive’. The literature contains a number of references to another...
متن کاملRapid Detection of Campylobacter jejuni by Polymerase Chain Reaction and Evaluation of its Sensitivity and Specificity
Introduction: Campylobacter jejuni is one of the most common causes of food poising in humans. Rapid and specific detection of these bacteria has an important role in diagnosis and treatment of infection. The aim of this study was to design a specific PCR for the detection of Campylobacter jejuni. Methods: In this experimental study, oxidoreductase gene from the Campylobacter jejuni was sele...
