Antibiotic Sensitivity Testing

Method of testing antibiotic sensitivity of spirochaetes, using antibiotic discs.

A rapid method of evaluating the susceptibility of spirochaetes to antibiotics would be convenient for investigators. Schneierson (1954) described a method of testing the susceptibility of strains of potentially pathogenic species, in which discs containing standard amounts of antibiotics were dropped into broth, and the broth was inoculated with the organism under study. He found that the resu...

A new technique for testing antibiotic sensitivity.

Antibiotic sensitivity testing in bacterial endocarditis.

Seventy-one blood cultures were taken from 26 suspected cases of bacterial endocarditis. Antibiotic sensitivity pattern was determined in 29 positive cultures. Gentamycin was found to be the most effective. Cloxacillin, chloramphenic.o1,vibramycin, tetracycline, erythromycin were next in order (J PMA 33 87,1983).

Comparison of tablets and paper discs for antibiotic sensitivity testing.

The value of tablets and paper discs as reservoirs of antimicrobial agents for use in sensitivity testing was compared. Antibiotics that were unstable in paper discs showed no demonstrable loss of activity in tablets over a period of 50 days under adverse storage conditions. The antibiotic content of commercially prepared tablets is very high in comparison with the accepted content of paper dis...

Choice of antibiotic for group B streptococcus in women in labour based on antibiotic sensitivity testing.

OBJECTIVE To determine whether pregnant women testing positive for Group B Streptococcus (GBS) are receiving appropriate antibiotic prophylaxis in labour based on sensitivity testing. METHODS We performed a retrospective chart review of all women who delivered at our institution from January 1 to December 31, 2008. We identified all GBS-positive women, and then abstracted data regarding demog...
