aureus identification, coagulase production (coagulase test) has been considered as an important criterion for phenotypic identification (Upadhyay et al.
They included: Indole test, methyl red test (MR), citrate utilization, catalase test, oxidase test, coagulase test, oxidation--fermentation test, fermentation of sugars, and motility test.
Gram positive Staphylococci colonies with a positive coagulase test (17) were inoculated onto Mueller-Hinton agar containing 6 ig/ml Oxacillin and incubated for 24 hours at 37[degrees] C to determine their sensitivity to the antibiotic.
Q Concerning the tube coagulase test, I have always known to store (freeze) the bovine serum in glass tubes (12 mm x 75 mm).
These isolates were then re-identified by gram staining, Catalase test, Coagulase test, DNAse test and preserved in 20% v/v glycerol in brain heart infusion (BHI) at-70AdegC till further use.
Speciation of CoNS was done based on Kloos and Schleifer classification and Koneman [1,2] by studying the colony morphology on nutrient agar, Gram reaction of smear, Haemolysis on blood agar, Mannitol salt agar, Catalase test, Coagulase test, Modified oxidase test, nitrate reduction test, Voges-Proskauer test, Urease test, Oxidative fermentative test, DNAse test, Phosphatase test, Ornithine decarboxylase, Sugar fermentation-Glucose, lactose, Mannitol, Mannose, Trehalose, Xylose, Novobiocin and Polymyxin B 300 Susceptibility test.
Strain typing was done by biochemical methods including colony characteristics, Gram staining, and coagulase test. Methicillin resistance was determined according to the Clinical and Laboratory Standards Institute (CLSI) guidelines (M100-S23).6
