Screening pneumococci for penicillin resistance.
Eighty-four pneumococci with various MICs of penicillin (38 with MICs of less than or equal to 0.06 micrograms/ml [susceptible], 35 with MICs of 0.12 to 1.0 micrograms/ml [relatively resistant], and 11 with MICs of greater than 1.0 micrograms/ml [resistant] ) were screened by a disk diffusion test using oxacillin and methicillin to see how well they distinguished penicillin-susceptible strains ...
متن کاملA rapid bile solubility test for pneumococci.
The observation that pneumococci when grown in an anaerobic atmosphere with 10% CO2 produce characteristically large colonies (Howden, 1976) called for a simple rapid confirmatory test; in this way a precise report could be issued on the morning of isolation. Hawn and Beebe (1965) described a solubility test for aerobic pneumococcal colonies using a sodium deoxycholate solution (pH 70). Aerobic...
متن کاملUse of an oxacillin disk screening test for detection of penicillin- and ceftriaxone-resistant pneumococci.
In a context of worldwide emergence of resistance among Streptococcus pneumoniae strains, early detection of strains with decreased susceptibility to beta-lactam antibiotics is important for clinicians. If the 1-microgram oxacillin disk diffusion test is used as described by the National Committee for Clinical Laboratory Standards, no interpretation is available for strains showing zone sizes o...
متن کاملScreening test for hydrindicuria.
VEil-GROWING evidence indicates that time indole nmetabohsm imas a major role in mental illness. in i)levious publications (1, 2) we reported time i(lemmtification, isolation, and the pui-ificatiomm of some unusual iimdolic substances from the urine of a nmentally ill child. It was foummd that the chi-ornogeim of the emid pm-oduct was hydrindic acid, and the intermediate substances were dem-ive...
متن کاملA screening test for phaeochromocytoma.
Patients suffering from phaeochromocytomata excrete many times the normal amount of noradrenaline in the urine (Euler, 1951). Determination of the excretion of noradrenaline in thu urine over 24 hours is thus a valuable aid to the diagnosis of this condition. Few clinical laboratories, however, have the facilities for noradrenaline assay, and there is a need for a simple, reliable, and fairly r...
