[Role of chlamydia in chronic renal and urogenital diseases in man].
Serological examinations by the CFT with the group-specific ornithosis antigen were carried out with 1910 sera from patients with chronic diseases of the kidneys, urinary tracts and male sexual organs, as well as with 556 control sera from patients with cardio-vascular and other diseases for elucidation of the role of chlamydia (OLT group) in the infectious pathology of the kidneys and urinary tracts of man. No complement-fixing antibody was detected with the group-specific ornithosis antigen in control sera. The antibody was found in 5.2% of sera from patients with chronic diseases of the kidneys and upper urinary tracts and in 6.2% of cases with the involvement of the proximal part of the urinary tracts and male sexual organs. The intradermal test (IDT) with ornithosis allergen was performed for those patients whose sera contained complement-fixing antibody. The results of CFT and IDT coincided in 82.8% of the patients, thus confirming the etiological role of chlamydia in human urogenital pathology. Studies on the positive sera with the species-specific ornithosis antigen gave negative results, indicating that a distinct species of chlamydia is the agent of urogenital diseases.
Screening for antibody to Chlamydia pneumoniae by the complement fixation test.
We performed a retrospective survey for antibody to Chlamydia pneumoniae, by the microimmunofluorescence (MIF) test, on 120 sera that were previously determined to be positive for antibody to ornithosis antigen by the complement fixation (CF) test. The panel of sera comprised 40 paired acute and convalescent sera, and 40 single samples, from 80 patients. Of these patients, 60% were considered to be serologically positive for C. pneumoniae, based on the antibody titers of IgG, IgM, or both. There was no association between the CF titer to ornithosis antigen and the respective IgG or IgM MIF antibody titers. We propose that, in those laboratories routinely using the CF test, sera found to be positive for ornithosis antigen should be further tested by the MIF in order to clarify, both from an epidemiologic and clinical perspective, whether these patients are also serologically positive for C. pneumoniae.
[Role of leukocyte disintegration products in increasing macrophage resistance to the causative agent of orinthosis].
The dymanics of formation of macrophagal granulomas in the liver of albino mice was studied after intravenous infection with the causative agent of ornithosis. In formation of granulomas macrophages underwent the stage of reutilization of the leukocyte disintergration and became resistant to the causative agent of ornithosis. Together with the leukocyte remants histones and cation proteins could penetrate into the macrophages cytoplasm; these displayed a high antironithosis activity in vitro. An increase of macrophage resistance to the causative agent after reutilization of the products of leukocyte disintegration apparently sreved as one of the mechanisms of resistance formation in the foci of inflammation in ornithosis.
The prevalence and regional distribution of antibodies against Chlamydia pneumoniae (strain TWAR) in Finland in 1958.
The occurrence of nonavian 'ornithosis' was reported in Scandinavia at the end of the 1950s. In order to find out whether Chlamydia pneumoniae had been present in Finland, we examined the IgG antibody prevalence to C pneumoniae in samples representing the whole rural population of Finland in 1958. The total number of sera studied using micro-immunofluorescence was 2000. Trend-surface analysis was used to examine the regional patterns of antibody prevalence. C pneumoniae antibodies were present throughout the country. The mean antibody prevalence was 56% among adults and 27% among children. Thus the possible role of C pneumoniae in nonavian 'ornithosis' in Finland between 1958 and 1960 cannot be excluded.
Serological examinations of crows in Colombo's slaughter-house Sri Lanka.
Crows from Colombo's slaughter-house were examined serologically towards ornithosis, Rickettsia, Newcastle Disease and Adenovirus. Positive reactions were shown in ornithosis, Q-fever, RMSF-Rickettsia-group and Adenovirus.
A serological survey of sera from domestic animals on Easter Island.
Animals' sera collected on Easter Island from December 1964 to February 1965 were tested by appropriate methods for the presence of antibodies to various infections. These included, ornithosis, Q-fever, brucellosis, Johne's disease, leptospirosis, toxoplasmosis and vesicular stomatitis viruses. It appeared that the cattle and sheep were exposed to the ornithosis group of agents. The sheep were also exposed to toxoplasmosis. The low-grade reactions observed on the cattle sera with the leptospira and brucella antigens were not sufficient to indicate past infection. All sera tested with Q-fever and Johne's disease antigens gave negative reactions. The results suggested that neither strain of vesicular stomatitis virus had yet been introduced into this restricted animal population.
[Use of a cryoultramicrotomy method for the purpose of studying chlamydial ultrastructure].
The method of cryoultramicrotomy was adapted for the study of the ultrastructure of HeLa and McCoy cells in monolayer cultures infected with Chlamydia, obligatory intracellular procaryotic parasites, the causative agents of ornithosis (strain Loth) and paratrachoma (strain LB 1). The cryosections were obtained by the fixation of the monolayer with 2.5% glutaraldehyde, by the gradual infiltration of precipitated cells with sucrose (0.6--1.2--1.8--2.3 M) prior to freezing in liquid nitrogen, and by the treatment of sections with 1% aqueous methyl cellulose solution before drying. This method ensured good preservation of both Chlamydia, in intracytoplasmic inclusions and host cells, as well as regular reproducibility of the results. Ultrathin sections showed a considerable polymorphism in the vegetative forms of Chlamydia, which was probably due to the structure of their cell walls. Chlamydia, were found to form small vesicle-like structures in the cavities of inclusions. The cell walls and granules inside the elementary bodies of the causative agent of ornithosis were stained with the use of phosphotungstic acid--HCl, pH 0.5.
[Biology of a newly isolated agent of the Chlamydia group].
The results of identification of the agent ("Progress" strain) isolated from the organs of a calf sacrificed in the early stage of pneumonia are presented. The agent adapted to yolk sacs of chick embryos was pathogenic for white mice by the intracerebral route and for monkeys infected with aerosol. The infected animals developed specific complement-fixing antibody. The antigen of the agent reacted in the CFT with homologous immune sera and with sera against ornithosis and other members of the ornithosis-lymphogranuloma-trachoma (OLT) group. In cell cultures the agent multiplied well and produced cytoplasmic inclusion bodies characteristic of the OLT group members.
[Role of Chylamydia in the pathology of pregnancy and chronic gynecological diseases].
For the elucidation of the role of chlamydial infection in pathological pregnancies, serological examination by the CFT with group-specific and species ornithosis antigen was carried out on 723 blood serum specimens from women with obstetrical pathology, 124 specimens from patients with various chronic gynecological diseases and 124 control blood serum specimens from women with nromal pregnancy and favourable obstetrical anamnesis. The complement-fixing antibody (CF) was detected in 72 (9.9%) serum specimens from women with obstetrical pathology and chronic gynecological diseases. No CF antibody was found in control sera. Negative results of the CFT were obtained with species ornithosis antigen in all sera. In parallel examinations of the blood serum specimens from women with obstetrical and gynecological pathology by the CFT and intradermal test, correlation of positive results was demonstrated in 62.5% of the patients. Among the women with positive reactions for chlamydial infection, in 52.8% thee pregnancy was pathological. Among 52 sero-positive pregnant women the death of the fetus was observed in the perinatal period in 21.2%. Among 111 babies born alive after previous pregnancies 55 babies (49.5%) died at the age under 1 year. Thus, chlamydial infection may possibly have causative relation to pathological pregnancy, death of the fetus in the perinatal period, and death of the babies under 1 year.
X-linked lymphoproliferative syndrome. A new kindred with variable phenotypic expression.
A kindred with five affected maternally related male members showed variable phenotypic expression of the X-linked lymphoproliferative syndrome. In one of the children, agammaglobulinemia developed following infectious mononucleosis. His brother had aplastic anemia in infancy and 21/2 years later died of overwhelming pneumonia resulting from ornithosis. A third brother died of reticulum cell sarcoma. Two maternally related male cousins died of reticulum cell sarcoma of the neck.
Serological evidence of Chlamydia trachomatis infection in non-immunocompromised adults with pneumonia.
Serological evidence of Chlamydia trachomatis infection in three non-immunocompromised adults with pneumonia is presented. Complement fixation (CF) tests indicated chlamydial infections in all three patients. These illnesses would have been erroneously regarded as ornithosis if microimmunofluorescence (Micro-IF) tests had not been performed because the CF test detects genus-specific antibodies while the Micro-IF test reveals species-specific antibodies.
