Rapid hippurate hydrolysis method for presumptive identification of group B streptococci.
A rapid test to detect the hydrolysis of sodium hippurate by beta-hemolytic streptococci within 2 h was developed. All group B streptococci tested were positive using this method and all other groups were negative.
متن کاملCAMP-disk test for presumptive identification of group B streptococci.
The modification of the CAMP test for goup B streptococci involved substituting a paper disk impregnated with partially purified beta-hemolysin for the staphylococcal culture that was the source of beta-hemolysin in the original test. The disk is placed onto a sheep blood agar plate beside the streak of Streptococcus being tested. The plate is then incubated aerobically at 35 degrees C. A posit...
متن کاملRAPID IDENTIFICATION OF GROUP A STREPTOCOCCI BY PYRROLIDONYL-β-APHTHYLAMIDE HYDROLYSIS
In a clinical trial a new pyrrolidonyl-β-naphthylamide (PYR) hydrolysis test was compared with the bacitracin disk susceptibility test for accuracy in the presumptive identification of group A streptococci (GAS). Among 128 isolates of beta-hemolytic streptococci 93 group A isolates were found. The sensitivity of the PYR and bacitracin tests were similar (98.9%), but the bacitracin test had ...
متن کاملPresumptive identification & antibiotic susceptibility of group B Streptococci.
Three presumptive identification tests were conducted on 60 strains of beta haemolytic group B streptococci (GBS) & evaluated for their sensitivity as compared to the standard serological grouping. The GBS were further subjected to serotyping and antibiotic sensitivity testing. Hippurate was hydrolysed by 96.6%, the CAMP test was positive in 83.3% & pigment was produced by 95%. The commonest se...
متن کاملEvaluation of the rapid hippurate hydrolysis test with enterococcal group D streptococci.
The rapid hippurate hydrolysis test was evaluated with the conventional test, using 17 group A streptococci, 9 non-enterococcal group D streptococci, 108 enterococcal group D streptococci, and 2 strains of Listeria monocytogenes. There was complete correlation between the rapid and conventional tests with all organisms except enterococcal group D. The rapid hippurate hydrolysis method was more ...
