Evaluation of spot CAMP test for identification of group B streptococci.
The CAMP (Christie-Atkins-Munch-Petersen) test is commonly used for the presumptive identification of Streptococcus agalactiae (Lancefield group B). Using 350 clinical isolates of beta-hemolytic streptococci, we compared a 30-min spot CAMP test with the standard overnight CAMP test and the Lancefield precipitin test. We found 99% agreement among all three tests for all streptococci tested. The ...
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 کاملModified Spot CAMP Test: A rapid, inexpensive and accurate method for identification of group B streptococci.
A rapid modified spot CAMP test using 183 clinical isolates of beta haemolytic streptococci was compared with the standard CAMP test described by Christie et al. The scheme of biochemical identification and serological confirmation was taken as reference method. The sensitivity of both tests was 100%, and the specificity of the rapid and standard tests was 96.8% and 88.9% respectively. The modi...

alpha toxin derived from clostridium perfringens was used for diagnosis of streptococcus agalactiae (st.agalactiae) by rapid and spot camp tests. the selected cl.perfringens strain was cultured in optimized conditions; the supernatant of culture was concentrated by ultra filter and purified by deae cellulose chromatography. the efficacy of both purified and crude α-toxins were examined by rapid...
متن کاملModified method for serological identification of group B streptococci.
Extracts from 10- and 40-ml cultures compared favorably for serological identification of group B streptococci. Typing by gel diffusion proved reliable and efficient. These modifications save time, media, and antisera.
