| cell-mediated immune responses in owl monkeys (aotus trivirgatus) with trachoma to soluble antigens of chlamydia trachomatis. | the first temporal study of the cell-mediated immune responses (cmi) following ocular infections with chlamydia trachomatis is presented. we examined the cmi of owl monkeys infected with trachoma to soluble antigens of c. trachomatis by leucocyte migration inhibition (lif) and delayed hypersensitivity skin testing. delayed hypersensitivity of a systemic nature developed after a local eye infection in owl monkeys; clearance of inclusions from conjunctival cells coincided with the onset of this re ... | 1978 | 101327 |
| studies of the viral flora in keratoconjunctivitis sicca. | fifty patients suffering from kcs and exhibiting various patterns of corneal staining with fluorescein were examined for adenovirus types 3, 7, 8, and 14, herpes simplex, and the tric group by tissue culture and immunofluorescein techniques. no viruses were detected by either methods, and it is considered that presumption of virus involvement in these cases is untenable. | 1975 | 164882 |
| etiology of nongonococcal urethritis. | chlamydia trachomatis was isolated from the urethra from 48 (42 per cent) of 113 men with non-gonococcal urethritis (ngu), four (7 per cent) of 58 without overt urethritis, and 13 (19 per cent) of 69 with gonorrhea. postgonococcal urethritis (pgu) developed in 11 of 11 men who had c. trum antibody to c. trachomatisis developed. the immunotype specificity of chlamydial antibody corresponded to the immunotype isolated. among culture-negative patients. chlamydial antibody prevalence correlated with ... | 1975 | 165407 |

| a serologic survey of pronghorns in alberta and saskatchewan, 1970-1972. | to determine the exposure of free-ranging pronghorns (antilocapra americana ord) to selected pathogens, serum samples were obtained from 33 live-trapped animals from southwestern saskatchewan in 1970, and from 26 and 51 animals from southeastern alberta, in 1971 and 1972, respectively. antibodies were found to the agents of parainfluenza 3, bovine virus diarrhea, eastern and western encephalomyelitis, infectious bovine rhinotracheitis and the chlamydial group. no serologic reactors were found to ... | 1975 | 167203 |
| streptovirudins, new antibiotics with antibacterial and antiviral activity. i. culture taxonomy, fermentation and production of streptovirudin complex. | a new antibiotic complex has been isolated from cultures of streptomyces strain no. ja 10124. on the basis of taxonomic studies, the producing microorganism is described as streptomyces griseoflavus (krainsky, 1914) waksman et henrici, 1948, subsp. thuringiensis subsp. nov., type strain ja 10124. the antibiotic complex, designated as streptovirudin, was isolated from extracts of both mycelium and culture filtrate. it is a white amorphous material which consists of ten closely related components ... | 1975 | 168173 |
| importance of the so-called 'other' sexually-transmitted diseases. | (1) some data are presented concerning the frequency and potential morbidity of sexually-transmitted organisms other than t. pallidum or n. gonorrhoeae. (2) most of the diseases with which these organisms are associated are more prevalent than syphilis and some, at least in one sex, are as common as gonorrhoea. a number appear to carry considerable morbidity, which in the case of type ii herpes virus--if it is responsible for cervical cancer--may ultimately cause more fatalities than syphilis.

| [morphological manifestations of the intracellular toxic effect of microorganisms of the ornithosis-lymphogranuloma-trachoma group]. | interactions of the causative agents of meningopneumonia and ovine abortion with pulmonary macrophages in experimental infection in white mice were studied by histological, immunofluorescent and electron microscopic methods. the causative agent of meningopneumonia did not multiply in colonies and caused toxic lesions in the cells and formed cytoplasmic oxiphilic inclusion bodies. being the product of cell degeneration, these oxiphilic inclusion bodies were conducive to long-term survival of the ... | 1975 | 169631 |

| chlamydia trachomatis cervicitis in gynecologic outpatients. | symptoms suggestive of a lower genital tract infection (lgti) are common complaints in women who consult gynecologists. sexually transmitted microorganisms, such as chlamydia trachomatis. neisseria gonorrhoeae, and trichomonas vaginalis, are responsible for a substantial proportion of lgti. this study was performed to establish the frequency of lgti caused by c trachomatis in women attending a gynecologic outpatient clinic. of 170 women with lgti, 32.9% harbored one or more of these organisms: c ... | 1978 | 104212 |
| search for uro-genital tract infections in patients with symptoms of prostatitis. studies on aerobic and strictly anaerobic bacteria, mycoplasmas, fungi, trichomonads and viruses. | seventy-nine patients with symptoms of nonacute prostatitis and 20 healthy volunteers were examined for uro-genital tract infection with bacteria, mycoplasmas, fungi, trichomonads and viruses. no differences in the results of the bacterial cultures were found between the patients and the controls. in only a few cases were established urinary tract pathogens found, but in no instance were these findings reproducible in later specimens. the cultures of the expressed prostatic fluids and the sample ... | 1975 | 175434 |

| isolation of chlamydia trachomatis from bartholin's ducts. | exudate from bartholin's ducts from 30 selected patients was investigated for chlamydia trachomatis and neisseria gonorrhoeae. n. gonorrhoeae was isolated from the duct exudate in 24 patients and c. trachomatis in nine. concurrent infection of the ducts was present in seven (29.2%); the remaining two patients were sexual contacts of men with non-specific urethritis. the duct exudate was mucopus in seven patients, cloudy mucus in one, and clear mucus in the other. although contamination of the vu ... | 1978 | 104771 |
| experimental acute salpingitis in grivet monkeys provoked by chlamydia trachomatis. | chlamydia trachomatis is a common cause of sexually transmitted diseases. recently it has been shown that chlamydiae are also responsible for complications to such lower genital tract infections. in this study, isolates of c. trachomatis from the fallopian tubes of patients with acute salpingitis were inoculated direct into the fallopian tubes of two, and through the cervical canal into the uterine cavity of one grivet monkey. the experimental infections resulted in a self-limited acute salpingi ... | 1979 | 107723 |
| chlamydia trachomatis in acute salpingitis. | in a study to evaluate the possible role of chlamydia trachomatis and neisseria gonorrhoeae in acute salpingitis, 26% of 106 patients with severe symptoms had positive culture results for c. trachomatis; 43% of the 72 patients from whom paired sera were obtained had either positive culture results for or seroconversion in the single antigen immunofluorescence test to c. trachomatis. twenty-six per cent of patients harboured n. gohorrhoeae and 14% had gonococcal complement-fixing antibody titres ... | 1979 | 111767 |
