| growth of chlamydia trachomatis in mccoy cells treated with cytochalasin b. | when the fungal metabolite cytochalasin b was added to mccoy cells, multinucleated giant cells developed. monolayers of these cells proved as efficient as irradiated cells for the growth of three different serotypes of chlamydia trachomatis and for the primary isolation of chlamydiae from clinical specimens obtained from patients attending a venereal disease clinic. cytochalasin treatment of mccoy cells provides a convenient alternative to irradiation and should be of value in the isolation of c ... | 1974 | 4451373 |

| purification on renografin density gradients of chlamydia trachomatis grown in the yolk sac of eggs. | chlamydia trachomatis grown in the yolk sac of embryonated eggs was purified by centrifugation on continuous isopycnic renografin density gradients. a band of chlamydial particles with a buoyant density of 1.20 contained 70% of the starting particles, and electron microscopy revealed the virtual absence of contaminating egg material. centrifugation on renografin gradients caused only a moderate decrease in infectivity. for large-scale purification, infected yolk sac was centrifuged through renog ... | 1974 | 4855645 |
| cycloheximide-resistant glycosylation in l cells infected with chlamydia psittaci. | l cells (mouse fibroblasts), uninfected and infected with the meningopneumonitis strain of chlamydia psittaci, were labeled with [(14)c]glucosamine, and their membranous organelles were separated by isopycnic equilibrium centrifugation of whole cell homogenates on discontinuous sucrose gradients. glycosylation of host membranes continued throughout the infection. cycloheximide almost completely inhibited glycosylation in uninfected l cells, but it only partially inhibited the process in infected ... | 1974 | 4856239 |
| hemagglutinin in cell walls of chlamydia psittaci. | intact purified elementary bodies (eb) of chlamydia psittaci agglutinate chicken erythrocytes in low titer, whereas homogenates of eb and of eb cell walls agglutinate at much higher titers depending on the extent of disruption by shaking and sonication. the hemagglutinin is contained in the cell envelope and can be purified with cell wall fractions. treatment of cell wall with sodium dodecyl sulfate completely inactivated the hemagglutinin. purified hemagglutinin was found to have an identical p ... | 1974 | 4856587 |

| isolation of chlamydia trachomatis by use of 5-iodo-2-deoxyuridine-treated cells. | irradiated mccoy cells have provided a useful technique for the isolation of chlamydia trachomatis strains, among which are found the etiological agents of trachoma, inclusion conjunctivitis, and lymphogranuloma venereum. because irradiation is not always readily available, 5-iodo-2-deoxyuridine (iudr) treatment of cells was investigated as a substitute procedure. iudr-treated cells were found to be as sensitive to c. trachomatis infection as were irradiated mccoy cells. stock chlamydial strains ... | 1974 | 4598224 |

| in vitro effect of leukocytic and thymic histones and their fractions on the activity of the causative agent of meningopneumonia. | it was found in studying the antimeningococcus activity of the leukocytic and thymus histones and their fractions that both histones were capable of neutralizing in vitro the activity of the causative agent of meningopneumonia (mp). the neutralization effect was chiefly associated with the f3 fraction rich in arginine and depended on the duration of the histone fraction contact with the mp causative agent, the weight concentration of the histone and the ph of the incubation medium. | 1975 | 1947 |
| cytology as a guide to the presence of chlamydial inclusions in giemsa-stained conjunctival smears in severe endemic trachoma. | microscopical examination of 927 giemsa-stained conjunctival smears from children with chronic trachoma in southern tunisia showed 93 (10 per cent.) with typical trachoma (chlamydial) inclusions in epithelial cells. the accompanying cytological features were a useful indicator for inclusions. inclusions were found only in slides with numerous polymorphonuclear neutrophils (pmns) and separation of the epithelial cells. when these two features alone were present, 3 per cent. of the smears were inc ... | 1975 | 48384 |

| are chlamydial infections the most prevalent venereal disease? | we studied two population groups (more than 1,600 patients) to determine the prevalence and clinical associations of genital tract infections with chlamydiae and herpesviruses. base-line isolation rates for asymptomatic women having routine pelvic examinations were much lower than rates for symptomatic women. in both groups, chlamydiae were more prevalent than herpesviruses. chlamydial infection was associated much more commonly with cervicitis (36.6%) than with vaginitis only (4.1%). among 282 ... | 1975 | 163932 |
| isolation of chlamydia from patients with urethritis. | from october 1973 through august 1974, 335 genitourinary tract specimens from patients with urethritis were inoculated into mccoy's cell cultures for the diagnosis of chlamydia infections. of the 45 chlamydia isolates, 42 were recovered when glass vials rather than plastic microtiter plates were used as cell culture vessels. herpes simplex virus was isolated 15 times. bacterial overgrowth occurred 42 times; however, in 20 specimens the contamination was not apparent until after the first sub ... | 1975 | 163942 |

| 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 |

| 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.

| chlamydia trachomatis immunotype j. | a new immunotype j is proposed for a group of chlamydia trachomatis strains which are related to trachoma type c in the microimmunofluorescence typing test. ten immunologically identical strains have been identified from four separate areas of the world. the strains were either isolated from the genital tract or from eye infection originating from the genital tract. they grow readily in hela 229 cell culture but poorly in egg culture. whereas two-way cross-reactions were found between types c an ... | 1975 | 810514 |
| chlamydial infection of the male baboon urethra. | two adult male baboons (papio cynocephalus) were infected by urethral catheter with a type d strain of chlamydia trachomatis isolated from a male patient with nongonococcal urethritis. chlamydial organisms were shed from the urethra for about 90 days and serum antibody developed. intraurethral re-inoculation of homologous and heterologous (type i) strains of chalmydia, 4 and 11 months later, resulted in relatively shorter periods of infection of less than 15 days. the antibody titres and type-sp ... | 1975 | 811318 |

| neutralization of chlamydia trachomatis in cell culture. | neutralization of chlamydia trachomatis was assayed by the decrease in inclusion-forming units in baby hamster kidney cells grown in culture. five percent fresh guinea pig sera increased neutralization titers of rabbit antisera 100- to 1,000-fold but had no effect when normal rabbit sera were tested. neutralization of a type a or b trachoma isolate was strain specific. neutralization by human eye secretions and sera also was demonstrated when guinea pig sera were included in the test. all of the ... | 1975 | 1091549 |
| serotyping of chlamydia: isolates of bovine origin. | chlamydial isolates of bovine origin were serotyped by a plaque reduction method. of the two major serotypes observed, type 1 included isolates from bovine abortion and enteric infections, whereas type 2 isolates were associated with polyarthritis or encephalomyelitis. these two serotypes were identical to those with a similar disease distribution previously observed in isolates of ovine origin. the two groups did not cross-react and they were serologically unrelated to chlamydiae of avian origi ... | 1975 | 1091564 |
