serological cross-reactions between acinetobacter calcoaceticus and chlamydiae.a cross-reaction between acinetobacter calcoaceticus and chlamydiae is described. a water-soluble, heat stable, non-dialyzable antigen was extracted from acinetobacter species by boiling. this antigen fixed complement in the presence of homologous hyperimmune sera from rabbits or guinea pigs and in the presence of heterologous human or hyperimmunized animal sera containing chlamydial antibodies. hyperimmune antisera to the extracted antigen, or to suspensions of live acinetobacters, also reacted ...1979521480
differential neutralization of spontaneous and centrifuge-assisted chlamydial infectivity.neutralization by specific antibody of a fast-killing variant strain of chlamydia trachomatis, which showed high spontaneous infectivity for cell monolayers, was examined. it appeared that in spontaneous infection antibody-treated chlamydiae were neutralized by inhibition of attachment to cells. centrifugation imposed a different effect: infection was inhibited at some step at or subsequent to attachment.1979521795
role of gastric antrum in gastric and intestinal phases of gastric secretion in dogs.1. the gastric and intestinal phases of gastric secretions were selectively evoked before and after the removal of the antral mucosa in four dogs provided with a special cannula that allowed complete separation of the stomach and duodenum without interrupting neural connexions between them. 2. the gastric phase induced by 5% liver extract meal administered into the stomach at various distension pressures (ranging from 0 to 15cm h2o) resulted in an increase in acid output to about 56% of the hist ...1979521927

medical aspects of power generation, present and future.it can be seen that the radiation emissions of nuclear power plants are small indeed, compared to natural background radiation and other man-made sources of radiation. for example, the poulation is exposed to 100 times more radiation from television sets than from nuclear power reactors. the assumed risks to the people in this country from nuclear power reactors are also small compared to the normal risks which are tolerated in this society. the complete elimination of all hazards is a most diff ...1979522630
experimental granulomatous inflammation: ii. effect of injection of intact and disrupted killed tubercle bacilli into freund adjuvant-sensitized cavies.the reaction of freund adjuvant-immunized cavies to subsequent injection of mycobacterium tuberculosis h37ra is confirmed as an immunologically mediated phenomenon. ultrasonic disruption of mycobacteria to be injected as "challenge" markedly increases the intensity of the consequent 24-48 h reaction and subsequent fibrosis in freund adjuvant-sensitized cavies and has an apparently inhibiting effect on the extent of subsequent granuloma formation with marked reduction of the density of epithelioi ...1979523183
concurrent drinking by pigeons on fixed-interval reinforcement schedules.three experienced pigeons were exposed to at least ten consecutive 100-min sessions on each of three food-reinforced fixed-interval (fi) schedules: fi 50-sec, fi 100-sec and fi 200-sec. water was freely available. drinking was largely confined to the first third of each fixed interval, and the mean sessional water intake was directly related to the food-reinforcement rate for each animal. the animals drank very quickly, i.e., 3--4 ml/sec, but the drinking bouts were brief, i.e., 0.8--1.4 sec, an ...1979523557
high level of human growth hormone (hgh) in cerebrospinal fluid patients with pituitary tumors.six patients with suprasellar extension of pituitary hgh-secreting tumors showed the cerebrospinal fluid (csf) content in human growth hormone (hgh) to be very high, i.e. 164.3 +/- muu/ml (mean +/- sem) (range 8.4--413.8 muu/ml) as compared to ten patients with uncomplicated acromegaly whose values were 50-fold lower, i.e. 3.4 +/- 0.5 muu/ml (range 0.6--7.0 muu/ml), and nine patients with suprasellar extension of other pituitary tumors, showing also low levels of hgh in the csf, i.e. 2.9 +/- 0.8 ...1979504962
vibrissae removal and the phenomenon of unexplained sudden death.two earlier theories on the effect of vibrissae removal in rats were tested. one theory stating that vibrissae removal produces impairment of spatial orientation capacity was confirmed. the other stating that it causes a depressive state of hopelessness and sudden death could not be confirmed. it is concluded that the extrapolation from the particular animal experiment to human psychological processes is not justified.1979525245
pneumonia associated with chlamydia trachomatis infection in an infant.chlamydia trachomatis was isolated from the epipharynx of a 10-week-old baby girl taken ill with pneumonia but without signs of conjunctivitis. the infant developed specific antibodies to the organism. the course of the pneumonia was protracted, with cough and tachypnea. the baby, who was afebrile, improved on antibiotic therapy but pulmonary infiltrates persisted for several months. to our knowledge, this is the first case of pneumonia in an infant associated with c. trachomatis infection repor ...1979525346
chlamydia trachomatis genital infections.the prevalence and clinical features of chlamydia trachomatis infection were studied in men with nongonococcal urethritis (ngu), in their female sexual partners, and in other women. of 92 patients with ngu, 36 (39%) were chlamydia-positive; although all had symptoms of urethritis, fewer than half had evident discharge. clinical features of chlamydia-positive and chlamydia-negative ngu were indistinguishable. most female contacts of chlamydia-positive patients with ngu were infected with c. trach ...1979526844
antichlamydial antibodies in pelvic inflammatory disease.the role of chlamydia trachomatis in pelvic inflammatory disease (pid) diagnosed without laparoscopy was assessed by measuring antichlamydial antibodies in the patient's serum and by comparing the results with those in patients with uncomplicated non-specific genital infection (nsgi) and gonorrhoea and in non-infected controls. a modified microimmunofluorescence test was used. patients with severe pid had significantly more positive antichlamydial igg and igm results than did control subjects, p ...1979526845
chlamydia trachomatis infection of the fallopian tubes. histological findings in two patients.in two patients with acute salpingitis, c. trachomatis was isolated from the cervix. in one of the patients, the organism was also recovered from the fallopian tubes, and in the other, chlamydial inclusions were found in giemsa-stained tubal epithelial cells. a significant change in micro-immunofluorescence antibodies to c. trachomatis occurred in both patients during the course of the disease. the fallopian tubes of both patients were removed and studied by conventional histological techniques ...1979526846
identification of clinical isolates of selected species of bacteroides: production of phenylacetic acid.a total of 132 human clinical isolates were identified and tested for the production of phenylacetic acid. with the exception of b. vulgatus, b. melaninogenicus ss. melaninogenicus, and b. melaninogenicus ss. intermedius, all other species under study produced phenylacetic acid. this property can thus serve as a basis for faster characterization of the strains in clinical laboratories.1979526889

cultures of chlamydia trachomatis in mouse peritoneal macrophages: factors affecting organism growth.growth of chlamydia trachomatis b/tw-5/ot and l(2)/434/bu strains in cultures of thioglycolate-activated mouse peritoneal macrophages was studied. both strains grew to a limited extent in the macrophages, but lymphogranuloma venereum (lgv) grew better than trachoma. growth was enhanced by centrifugation of the inoculum onto the macrophage cell layer and inhibited by pretreatment of macrophages for 2 h with 100 mug of concanavalin a per ml. no significant effect was observed by pretreatment of ma ...1978566729
chlamydia trachomatis infant pneumonitis: comparison with matched controls and other infant pneumonitis.we determined the prevalence of chlamydia trachomatis infection in 30 consecutive hospitalized infants less than six months of age with pneumonitis and in 28 matched controls (nine of 30 vs. one of 28. p less than 0.05). in comparing 16 cases of pneumonitis due to c. trachomatis with 27 not due to that agent, we found several distinguishing clinical and laboratory features: c. trachomatis was highly correlated with radiographic hyperinflation, prolonged cough and congestion, greater than or equa ...1978628397
[doxycycline hyclate in the treatment of non-gonococcal urethritis].91 men with non-gonococcal urethritis (including urethritis due to chlamydia trachomatis and non-specific urethritis) were treated by a 14-day course of doxycycline hyclate; 75% were considered cured at follow-up on the 10th day and 3-4 months post-treatment. the results show a bettter cure rate (83%) in urethritis due to chlamydia trachomatis than in non-specific urethritis (64%). a 5-day course of doxycycline hyclate was disappointing and was followed by a very high recurrence rate in both gro ...1978628825
role of chlamydia trachomatis and hla-b27 in sexually acquired reactive arthritis.inflammatory arthritis, tendinitis, and fasciitis after non-specific urethritis ("sexually acquired reactive arthritis" (sara)) was studied prospectively in 531 men with non-specific urethritis, with particular reference to the frequency of isolation of chlamydia trachomatis and the presence of hla-b27. satisfactory cultures were obtained from the urethral swabs from 384 patients; and hla typing was performed on 482, of whom 30 (6%) were hla-b27-positive. arthritis developed in 16 patients, and ...1978630254
maternal genital chlamydial infection as a cause of neonatal conjunctivitis.infections of the cervix with chlamydia trachomatis are common, at least in those groups of sexually active women of child-bearing age who are seen in std (sexually-transmitted diseases) clinics. persistent untreated infection presents a hazard to the women themselves during pregnancy and to their infants who may develop chlamydial conjunctivitis. the clinical and laboratory findings in 1009 women and in 103 infants with conjunctivitis are presented. practical problems of diagnosis and control o ...1977593978
chlamydia trachomatis as a cause of acute "idiopathic" epididymitis.to assess the etiologic role of c. trachomatis and other micro-organisms in "idiopathic" epididymitis, 23 men underwent microbiologic studies, including cultures of epididymal aspirates in 16. eleven of 13 men under the age of 35 years had c. trachomatis infection whereas eight of 10 over 35 had coliform urinary-tract infection. cultures of epididymal aspirates yielded c. trachomatis alone in five of six men under 35, and coliform bacteria alone in five of 10 over 35. these results suggest that ...1978622087
division of single host cells after infection with chlamydiae.mouse fibroblasts (l cells) were infected in suspension with chlamydia psittaci (6bc) and then plated out on a solid substrate at a density of 80 cells per cm2 so that the effect of chlamydial infection on the division of single host cells and their progeny could be determined. uninfected l cells multiplied with a mean generation time of 15 h. the generation time of single l cells infected with 1.5 50% infectious units (id50) of c. psittaci was over twice as long. half of the infected l cells ha ...1978624590
chlamydia trachomatis as possible cause of peritonitis and perihepatitis in young women.of 11 young women with acute peritonitis proved by laparoscopy, seven of whom also had perihepatitis, nine had serological evidence of recent infection with chlamydia trachomatis; in five of these nine patients high antibody titres to chlamydiae were found without laboratory evidence of gonococcal infection, while the other four had evidence of simultaneous gonococcal infection. c trachomatis may play an important part in peritoneal inflammation previously attributed only to gonococci.1978638581
chlamydial infection of the urethra in men.chlamydia trachomatis was isolated from the uretha of 125 (52%) of 238 men with non-gonococcal urethritis (ngu). repeat isolation attempts in 155 of these patients were successful in eight men in whom results had been negative on the initial visit, but they were unsuccessful in eight men who initially had had positive cultures. we must assume that with our present isolation techniques we are missing, at any single visit, at least 9% of chlamydial infections. c. trachomatis was also found in 32 ( ...1978638714
the antimicrobial susceptibility of chlamydia trachomatis in cell culture.the action of 22 antimicrobial agents against the sa2f strain of chlamydia trachomatis has been studied by the use of a simple cell culture technique. tests for bactericidal activity were undertaken with some of the agents, and latency of infection was demonstrated. the susceptibilities of 10 clinical strains of c. trachomatis and of sa2f to oxytetracyline, erythromycin, and spectinomycin in cell culture were found to be identical.1978638716

prediction of efficacy of antimicrobial agents in treatment of infections due to chlamydia trachomatis.although chlamydia trachomatis is readily eradicated by systemic therapy in patients with acute urethritis, systemic therapy is less satisfactory in treatment of chronic trachoma. the activities of antimicrobial agents against c. trachomatis in cell cultures when the antimicrobial agents are added 1 hr after the c. trachomatis (minimal inhibitory concentration [mic]) predicts efficacy of the drugs in the treatment of urethritis but does not necessarily predict efficacy in the treatment of chroni ...1978712119

role of chlamydia trachomatis in non-acute prostatitis.the possible role of chlamydia trachomatis in non-acute prostatitis was investigated by cultural and serological techniques in a study of 53 adult males. c. trachomatis was isolated from the urethra of only one of the 53 patients and from none of the 28 specimens of prostatic fluid from the same patients. by means of a modified microimmunofluorescent test, serum chlamydial igg antibodies at a titre of 1/64 or greater, or igm antibodies at a titre of 1/8 or greater, or both were detected in six o ...1978709348

experimental infection of the chimpanzee urethra and pharynx with chlamydia trachomatis.an isolate of chlamydia trachomatis obtained from a man with nongonococcal urethritis was used to produce experimental urethral and pharyngeal infections in chimpanzees. after urethral inoculation of 8 x 10(1) inclusion-forming units (ifu), infections were established in three of three animals; urethral discharges developed in two. the infections persisted for five to nine weeks. larger inocular (7 x 10(2) and 1 x 10(5) ifu) produced pharyngeal infections in two animals. the third animal's phary ...1978741332
treatment of chlamydia-positive and chlamydia-negative nonspecific and postgonococcal urethritis.chlamydial and non-chlamydial nonspecific or postgonococcal urethritis in 132 men was treated with different regimens of chlortetracycline and doxycycline. chlortetracycline 250 mg four times daily for 12.5-18.5 days given to 70 men resulted in a clinical cure of urethritis in 80% of cases (56/70). there was no difference in the cure rate between chlamydia-positive (40) and chlamydia-negative (30) cases. in no instance was the treatment failure, i.e., re-appearance of urethritis, associated with ...1978742827
chlamydia trachomatis and pneumonia in infants: report of two cases.in two cases of pneumonia associated with chlamydia trachomatis in infants the symptoms began in the second week of life and the illness was severest at 4 weeks of age. both infants were afebrile. one had a history of conjunctivitis. both presented with a characteristic staccato cough and tachypnea but little evidence of peripheral airway obstruction. chest roentgenograms showed interstitial and alveolar pulmonary infiltration in hyperexpanded lungs. the serum igm concentrations were markedly el ...1978743659

etiologies of postgonococcal urethritis in homosexual and heterosexual men: roles of chlamydia trachomatis and ureaplasma urealyticum.before treatment for urethral gonorrhea, chlamydia trachomatis was isolated from 18% and ureaplasma urealyticum from 37% of 121 men. c. trachomatis was recovered from none of 18 homosexual men who had gonorrhea and from 22 of 95 heterosexual men who had gonorrhea (p less than 0.05). after treatment with a penicillin, postgonococcal urethritis occurred significantly more often in heterosexual than in homosexual men (p less than 0.002). postgonococcal urethritis developed in all men from whom c. t ...1978741335
examination of men with nongonococcal urethritis and their sexual partners for chlamydia trachomatis and ureaplasma urealyticum.chlamydia trachomatis was recovered from 39 (52%) of 75 men who had nongonococcal urethritis and from 28 (37%) of their sexual partners. of the partners of men with chlamydia-positive nongonococcal urethritis, 64% excreted chlamydia, compared with 8% of the partners of men with chlamydia-negative nongonococcal urethritis. in contrast, an apparently sexual mode of transmission was not observed with ureaplasma urealyticum. rates of recovery of u. urealyticum from men with nongonococcal urethritis ...1978725708

ophthalmia neonatorum due to chlamydia trachomatis: a family problem?the most frequently seen type of infectious ophthalmia neonatorum, inclusion conjunctivitis, is caused by the organism chlamydia trachomatis. this agent is known to be transmitted sexually. until recently, the infections produced by c trachomatis were though to be relatively benign. recent evidence, however, suggests that the organism may produce urethritis and epididymitis in the male; cervicitis, cervical erosions, salpingitis, and puerperal infections in the female; and prematurity and pneumo ...1979759548
chlamydiae, cervicitis, and abnormal papanicolaou smears.cervical abnormalities accompanied by papanicolaou class ii or class iii cytologic results are commonly encountered in gynecologic office practice. chlamydiae are a common cause of genital tract infection, with or without manifest symptoms or signs. an immunofluorescence method was used to determine the presence of antichlamydial antibodies in cervical secretions. eleven of 15 patients in whom such antibodies were found (73.3%) had papanicolaou class ii or class iii smears, in contrast to only 3 ...1979760016
