Kovacs indole reagent, p-dimethylaminobenzaldehyde, Ehrlich indole reagent and p-dimethylaminocinnamaldehyde were used as spot indole reagents to test 359 strains of gram-negative rods growing on 5% sheep blood agar, Trypticase soy agar (BBL Microbiology Systems), and MacConkey agar. The p-dimethylaminocinnamaldehyde reagent was the most sensitive of those tested and provided results that were ...

The growth and color change produced on dermatophyte test medium (DTM) by 25 strains of zoopathogenic fungi associated with human skin lesions were evaluated quantitatively. DTM only partially suppressed the development of nondermatophytes, with total growth in most instances comparable with that observed with dermatophytes. Whereas all dermatophytes induced a rapid color change on DTM, several...

The gonococcal complement-fixation test (GCFT), based on the same principle as the Wassermann reaction (WR), has been in use for over 60 years. The test was applied for the first time, using a culture of the gonococcus as antigen, by Muller and Oppenheim (1906) to establish the diagnosis in a case of arthritis. Teague and Torrey (1907) suggested that negative results in the GCFT were due to dif...

The need for a satisfactory test for pregnancy has long been felt, and numerous tests have been evolved for this purpose. A few of these may be mentioned. The Aschheim-Zondek (1928) test or its modifications depend on the demonstration of the anterior-pituitary-like hormone in the urine of pregnant women. Though this is widely accepted as the most accurate and certain test, it has several disad...

The aim of these three studies was to assess the test-retest reliability of the MIST (Melbourne Initial Screening Test), a new vision screening tool designed for use by vision screeners of preschool children and to determine the positive and negative predictive value. In the first study, 471 children participated in two sessions, either with the Sheridan Gardiner Singles (SGS) or the MIST. The ...
