induction of interferon in mice and cell cultures by mycoplasma pneumoniae.inoculation of mice and l and human embryonic lung (hel) cell cultures with mycoplasma pneumoniae failed to induce the production of interferon. m. pneumoniae multiplied in these cell cultures without a marked cytopathic effect. m. pneumoniae induced interferon in human peripheral blood leukocytes with maximum titres of 32 units/ml at 48 hours after infection.197723667
exacerbations of chronic bronchitis: exogenous or endogenous infection?six male patients with chronic bronchitis, who were known previously to have excreted streptococcus pneumoniae and/or haemophilus influenzae, both at the times of exacerbations and during remission, were studied for 43 to 52 months. sputum was examined fortnightly and at the time of exacerbations. strains of strep. pneumoniae were serotyped and those of haemophilus species were typed by antibiograms along with other supporting methods. sera collected before or at the time of an exacerbation and ...197825664
immunochemical studies on a mycoplasma pneumoniae polysaccharide fraction: cross-reactions with type 23 and 32 antipneumococcal rabbit sera.lipid-free polysaccharide fraction 2 extracted from mycoplasma pneumoniae strain fh by prescott et al. (j. bacteriol. 91:2117-2115, 1966) was examined for its ability to cross-precipitate antibody from type-specific rabbit antipneumococcal sera types 1 to 34 inclusive. cross-precipitation in type-specific pneumococcal anti-type 23 and anti-type 32 sera was examined in detail and could be attributed to a rhamnose-galactose-rich component of crude m. pneumoniae polysaccharide fraction 2 recovered ...197827459
morphological characteristics of acute respiratory tract diseases of mixed etiology in children.the analysis of 30 etiologically deciphered (by the direct coons method) autopsy observations of acute respiratory diseases in children under 8 is presented. monoinfections were established only in 6 cases. morphological examinations of respiratory organs in 24 cases of mixed acute respiratory diseases (associations of virus-bacteria and virus-mycoplasma pneumoniae-diplostreptococcus) revealed marked circulatory disorders and desquamative, dystrophic, and inflammatory processes in segmental bron ...197828114
the value of immunoelectroosmophoresis (ieop) for etiological diagnosis of acute respiratory tract infections due to pneumococci and mycoplasma pneumoniae.immunoelectroosmophoresis (ieop) has been used to detect pneumococcal and mycoplasma pneumoniae antigen in 324 sputum samples from 224 patients. pneumococcal antigen was found in 30/37 samples from which pneumococci had earlier been isolated and in 72/243 specimens where they had not been found. of these 72 samples 69 were from patients treated with antibiotics. mycoplasma antigen was found in 9/57 sputum samples from which mycoplasma had been isolated and in 2/32 other samples from patients wit ...197830990
serological diagnosis of pneumococcal disease with enzyme-linked immunosorbent assay (elisa).antibody response to pneumococcal type-specific polysaccharide was measured with enzyme-linked immunosorbent assay (elisa). the test was shown to be up to 500 times more sensitive than indirect hemagglutination using chromic chloride-treated red blood cells. in 16/17 patients with pneumococcal pneumonia a significant antibody increase was seen as measured with elisa. only 6/23 patients with pneumonia caused by mycoplasma pneumoniae gave a pneumococcal antibody rise and in those cases the increas ...197830991
the microbiology of serous and mucoid otitis media.one hundred forty-four serous and mucoid effusions were cultured for aerobic bacteria, mycoplasma pneumoniae, and virus. thirty percent of all effusions yielded an unequivocally positive culture for aerobic bacteria. although serous effusions were culture positive as often as mucoid effusions, haemophilus influenzae was isolated predominantly from serous effusions and staphylococcus epidermidis predominantly from mucoid samples. only one of 73 effusions yielded a viral isolate (herpesvirus homin ...197936591
adherence of erythrocytes to mycoplasma pneumoniae.the human pathogen mycoplasma pneumoniae adheres to a variety of cells, including erythrocytes. a hemadsorption technique was developed to quantitate adherence by photometric measurement of lysates of erythrocytes that attached to sheets of m. pneumoniae grown in cups of linbro plates. attachment of sheep erythrocytes (se) increased with higher ionic strength, was unaffected by minor ph variations (6 to 9), and was blocked by anti-m. pneumoniae antiserum, but was not inhibited by a variety of su ...197939034
adherence of mycoplasma pneumoniae to glass surfaces.attachment of m. pneumoniae to glass was quantitated in an experimental system enabling the settling down of [3h]palmitic acid-labeled cells onto glass cover slips. attachment of mycoplasmas suspended in buffer increased with temperature, decreased with higher ionic strength, and showed a maximum at about ph 5.5. the findings suggest a participation of ionic bonds in the attachment process. trypsin did not detach glass-bound mycoplasmas, and treatment of the cells with glutaraldehyde did not red ...197940883

[clinical evaluation of clindamycin-2-phosphate in infectious diseases (author's transl)].clindamycin-2-phosphate (7(s)-chloro-7-deoxylincomycin-2-phosphate) is a new semi-synthetic antibiotic. it is recognized that the drug itself is inactive against bacteria in vitro but it is hydrolyzed rapidly to active clindamycin, drug intramuscular or intravenous administration. clindamycin-2-phosphate was administrated intravenously to seven patients with infections, except one intramuscularly, 300 approximately 600 mg, every 8 or 12 hours a day, for 2 approximately 12 days. three patients (1 ...1977320361
viral antibodies in the sera from patients with parkinson disease.an assay of antibodies to 15 various viruses and mycoplasma pneumoniae was performed on the serum specimens from 441 patients with parkinson disease and from 443 healthy controls matched by sex, age, and place of residence, or from a representative group of these matched pairs. the main finding was a higher herpes simplex complement-fixing antibody level in patients with parkinson disease than in controls. patients with parkinson disease had higher herpes simplex antibody titers more often than ...1977323017
unexpectedly high frequency of antibody to mycoplasma pneumoniae in human sera as measured by sensitive techniques.mycoplasmacidal and radioimmunoprecipitating antibodies to mycoplasma pneumoniae were commonly detected in healthy children younger than five years of age, in whom natural disease due to m. pneumoniae is rare. antibody in serum could also be demonstrated in marine recruits several weeks or months before development of pneumonia due to m. pneumoniae. the latter observation suggests that serum antibody does not confer protection against disease caused by m. pneumoniae.1977323374
extraction of an actin-like protein from the prokaryote mycoplasma pneumoniae.an actin-like protein has been identified in cell extracts from the prokaryote mycoplasma pneumoniae. this protein bears a striking resemblance to actin from vertebrates: (i) the solubility of the protein during isolation is analogous to that of actin bound to myosin (soluble in high ionic strength salt solution and insoluble at low ionic strength), (ii) sodium dodecyl sulfate treatment of the partially purified m. pneumoniae extract produces a protein with an electrophoretic mobility very close ...1977333456
[study of antibiotic sensitivity in 34 strains of large colony mycoplasma (author's transl)].the application of steer's technic to large colony mycoplasma for the study of antibiotic sensitivities, permitted us to compare the activity of various molecules inhibiting protein synthesis. among large colony mycoplasmas, only mycoplasma pneumoniae is sensitive to erythromycin but we have already isolated a strain resistant at 400 microgram/ml. this should be remembered during treatment of mycoplasma pneumoniae infections. this species always remains sensitive to tetracycline. among the latte ...1977339167
activation of human lymphocyte subpopulations by mycoplasma pneumoniae.b- and t-cell-enriched preparations of lymphocytes from human blood (5 cases), adenoids (10 cases), and tonsils (4 cases) were examined for the in vitro stimulation response to mycoplasma pneumoniae (mp). b lymphocytes did not respond to mp by dna synthesis except for the b cells from one adenoid. t lymphocytes and nonfractionated lymphocytes from blood, from three of the adenoids and two of the tonsils showed a stimulation response to mp. nonfractionated adenoid lymphocytes from altogether 22 c ...1977339326
[illness due to mycoplasma pneumoniae in childhood (author's transl)].mycoplasma pneumoniae infection could be found in 16 from 92 children treated for respiratory disease in a hungarian hospital. it was verified by growth inhibition test or by culturing germs from bronchial secretions. seroology proved to be more effective than culture for identification. illnesses due to mycoplasma pneumoniae seem to be more frequent in the age group 0--3 years in hungary than they are in western countries in the same age group. the authors assume that this high frequency is cau ...1977339560
erythema multiforme and the stevens-johnson syndrome.erythema multiforme (em) is clinically characterized by a "minor" form and a "major" form. the latter is known as the stevens-johnson syndrome. infections (particularly herpes simplex and mycoplasma pneumoniae) and drugs seem to predispose toward the development of em. the pathogenesis is poorly understood. the treatment is supportive. prognosis varies with the severity of the eruption. recurrences are commonly seen.1978347587
a study of acute respiratory disease in the community of port chalmers. i. illnesses within a group of selected families and the relative incidence of respiratory pathogens in the whole community.a study of respiratory diseases in the semi-isolated community of port chamlers, new zealand, began in april 1973. the intensive surveillance of a selected group fo 26 families involved the weekly reporting of illness, the collection of specimens for virus, group a streptococci and mycoplasma pneumoniae isolation and the collection of sera at 6-month intervals. a total of 956 illnesses were reported during 32 months. the median number of illnesses per year were: infants 4.4, children 2.5, female ...1978357651

incidence and titres of smooth-muscle antibodies in human sera.by means of the indirect immunofluorescence method smooth-muscle antibodies (sma) were determined in 182 patients with various diseases and the findings were compared with those of 7 patients with chronic active hepatitis (cah) and 580 normal controls. igg-sma were found in 85.7% of the patients with cah, titres above 80 occurred only in hepatitis b-associated antigen (hbag)-negative cah, but igg-sma in low titres were also found with increased incidence in syphilis (16.7%) and in infections of ...1979373382
enhanced isolation of mycoplasma pneumoniae from throat washings with a newly-modified culture medium.two hundred throat washings, previously screened and presumed negative for mycoplasma pneumoniae in conventional mycoplasma culture media, were retested for the organism in a modified medium (ps-4) initially developed for cultivation of a tick-derived mycoplasma (spiroplasma). the organism was rapidly identified with an agar plate immunofluorescence procedure. m. pneumoniae was isolated from 69 (34.5%) of the 200 "negative" specimens cultured on a diphasic sp-4 medium, in contrast to 10 isolatio ...1979374649
