Evaluation of six media for the growth of Trichomonas vaginalis from vaginal secretions.
Schmid, G P, Matheny, L C, Zaidi, A A, Kraus, S J
Many media have been formulated for the growth of Trichomonas vaginalis, but the relative sensitivities of these media have not been determined. We evaluated the ability of six media, including all...
Larsen, S A, Hambie, E A, Pettit, D E, Perryman, M W, Kraus, S J
Using 920 sera, we compared the specificity and reproducibility of the hemagglutination treponemal test for syphilis with those of the fluorescent treponemal antibody-absorption test and the...
Isolation and identification of Haemophilus ducreyi in a clinical study.
Sottnek, F O, Biddle, J W, Kraus, S J, Weaver, R E, Stewart, J A
Seventeen strains of Haemophilus ducreyi were isolated from genital lesions which were negative for syphilis by dark-field examination. Media used for primary isolation at various times during the...
Interference by Neisseria gonorrhoeae growth by other bacterial species.
Kraus, S J, Geller, R C, Perkins, G H, Rhoden, D L
Growth of Neisseria gonorrhoeae from clinical specimens has been enhanced by the use of selective media that inhibit the simultaneous growth of other microorganisms. One explanation for this...
Isolation and characterization of a rough colony type of Neisseria gonorrhoeae.
Jacobs, N F, Kraus, S J, Thornsberry, C, Bullard, J
A new colony type of Neisseria gonorrhoeae was detected in the primary cultures from 8 of 180 men with gonococcal urethritis. This colony type contrasts with those previously described by having a...
Translucent culture media are essential for the determination of gonococcal colony types. In this study two hemoglobin-free, translucent culture media were compared with Thayer-Martin (TM) medium for...
Acquired and natural immunity to gonococcal infection in chimpanzees.
Kraus, S J, Brown, W J, Arko, R J
Despite the fact that gonorrhea is our most common reportable infectious disease, little is known about natural and acquired resistance to Neisseria gonorrhoeae. With the chimpanzee model, which...
Bacterial hemagglutination by Neisseria gonorrhoeae.
Koransky, J R, Scales, R W, Kraus, S J
Direct bacterial hemagglutination was investigated with 20 clinical isolates of Neisseria gonorrhoeae. The hemagglutination tests were performed by both a macrotechnique with glass slides and a...
Pathological features of experimental gonococcal infection in mice and guinea pigs.
Chandler, F W, Kraus, S J, Watts, J C
The histopathological and immunofluorescent findings in tissues within and surrounding artificially created subcutaneous tissue cavities infected with Neisseria gonorrhoeae for 1 to 30 days were...
Experimental animal infections with Mycoplasma hominis and Ureaplasma urealyticum.
Kraus, S J, Jacobs, N F, Chandler, F W, Arum, E S
Subcutaneous tissue cavities in mice and guinea pigs were infected with human isolates of Ureaplasma urealyticum and Mycoplasma hominis. The minimal infective dose for M. hominis was as low as less...
Development and Passive Transfer of Immunity to Gonococcal Infection in Guinea Pigs
Gonococcal infections of relatively long duration were produced in guinea pigs with minimal infective doses ranging from 101 to 102 colony-forming units. After spontaneous eradication and upon...

Increased serum immunoglobulin E concentrations in venereal diseases.
Green, R L, Scales, R W, Kraus, S J
Total serum immunoglobulin E (IgE) concentrations were determined by a competitive solid phase radioimmunoassay technique in serum samples from patients with a variety of venereal diseases. The mean...
