plasmid diversity in chlamydia.chlamydiae exhibit low interspecies dna homology and plasmids from different chlamydial species can be readily distinguished by southern blot analysis and restriction enzyme profiling. in contrast, available plasmid sequence data from within the species chlamydia trachomatis indicate that plasmids from human isolates are highly conserved. to evaluate the nature and extent of plasmid variation, the complete nucleotide sequences were determined for novel plasmids from three diverse non-human chlam ...19979202459
isolation of chlamydia pneumoniae from a carotid endarterectomy specimen.chlamydia pneumoniae has been associated with atherosclerotic cardiovascular disease by both seroepidemiologic studies and direct detection of the organism in atherosclerotic plaque by electron microscopy (em), immunocytochemistry (icc), and polymerase chain reaction (pcr). despite the frequent detection of the organism in atheromatous cardiovascular specimens by these methods, only 1 cardiovascular isolate of c. pneumoniae, obtained from a coronary artery, has been previously reported. this stu ...19979207386
evolutionary relationships among members of the genus chlamydia based on 16s ribosomal dna analysis.nucleotide sequences from strains of the four species currently in the genus chlamydia, c. pecorum, c. pneumoniae, c. psittaci, and c. trachomatis were investigated. in vitro-amplified rna genes of the ribosomal small subunit from 30 strains of c. pneumoniae and c. pecorum were subjected to solid-phase dna sequencing of both strands. the human isolates of c. pneumoniae differed in only one position in the 16s rrna gene, indicating genetic homogeneity among these strains. interestingly, horse iso ...19979209033

lymphocyte responses to chlamydia antigens in patients with coronary heart disease.to clarify the relationship of chlamydia pneumoniae infection and coronary atherosclerosis we studied cell-mediated and humoral immune responses to chlamydia in 93 patients with angiographically confirmed coronary heart disease and in 115 controls without angiographically demonstrable lesions.19979243142
epidemiology of encephalitis in children. a prospective multicentre study.we found 175 cases with acute encephalitis in a population of 791,712 children aged 1 month-15 years during a 2-year surveillance period in 1993-1994. the overall incidence was 10.5/100,000 child-years with the highest figure in children < 1 year of age, 18.4/100,000 child-years. the microbial diagnosis was considered proven or suggested in 110 cases (63%); varicella zoster, respiratory and enteroviruses comprised 61% of these, and adeno, epstein barr-, herpes simplex and rota viruses comprised ...19979243237
elevated chlamydia pneumoniae antibodies, cardiovascular events, and azithromycin in male survivors of myocardial infarction.the clinical significance of the association between elevated anti-chlamydia pneumoniae (cp) antibody titres and coronary heart disease (chd) is unclear. we explored the relationship between antibodies against cp and future cardiovascular events in male survivors of myocardial infarction (mi). the effect of azithromycin antibiotic therapy was assessed in a subgroup of post-mi patients.19979244203
[anti-chlamydia pneumoniae antibodies and production of interleukin 6 in acute myocardial infarct].chlamydia pneumoniae (c.p.) has been correlated with acute myocardial infarction (ami). high levels of anti-c.p. antibodies and circulating immune complexes containing c.p. lypopolyaaccharide (lps) antigens have been demonstrated in ami. lps antigen and especially chlamydial lps is one of the best antigen and it is also a very good interleukin inductor. moreover, interleukin 6 (il-6) has been observed in ami patients. the aim of our study was to assess the possible relationships between anti-c.p ...19979244752
incidence of community-acquired pneumonia requiring hospitalization. results of a population-based active surveillance study in ohio. the community-based pneumonia incidence study group.pneumonia is the leading cause of death due to infectious diseases in the united states; however, the incidence of most infections causing community-acquired pneumonia in adults is not well defined.19979250232
molecular biology of the chlamydia pneumoniae surface.chlamydia pneumoniaeis a fastidious microorganism with a characteristic biphasic lifecycle causing a variety of human respiratory tract infections. there is limited knowledge about the molecular biology of c. pneumoniae, and only a few genes have been sequenced. the structure of the chlamydial surface differs from that of chlamydia trachomatis. in order to study the surface of c. pneumoniae we generated monoclonal antibodies (mabs) against c. pneumoniae strain vr-1310 and selected 14 mabs that r ...19979259071
comparison of nasopharyngeal and throat swabs for the detection of chlamydia pneumoniae and mycoplasma pneumoniae by polymerase chain reaction.nasopharyngeal and throat swabs taken from 66 patients presenting at the department of infectious disease with symptoms of upper and lower respiratory tract infection were analysed by use of the polymerase chain reaction (pcr) for chlamydia pneumoniae and mycoplasma pneumoniae. a total of 18 patients (27%) were positive by pcr for c. pneumoniae. all 18 patients were positive from throat swabs, and three were also positive from nasopharyngeal specimens. the difference between the outcome of pcr u ...19979259072
assay of antibiotic susceptibility of chlamydia pneumoniae.it is well known that treatment of chlamydia pneumoniae infections is difficult. high doses and prolonged treatment is often needed to achieve clinical cure despite good in vitro effect of the drugs used. we here discuss different methodological problems in the determination of mic and mbc values of c. pneumoniae. the length of the preincubation time and the lack of fluctuation of the antibiotic concentrations may affect the outcome of the currently used assay.19979259073
animal models for chlamydia pneumoniae infection.there is accumulating evidence that persistent chlamydia pneumoniae infections occur in vivo. animal studies are necessary in order to evaluate the effects of different treatment regimens for eradication of such infections. a mouse model was found to be efficacious for the study of the effects of cortisone and antimicrobial agents on c. pneumoniae infection.19979259074
cell mediated immunity to chlamydia pneumoniae.the association of chlamydia pneumoniae to several chronic diseases such as atherosclerosis has been suggested serologically and by direct demonstration of organisms in disease lesions. cell mediated immunity is crucial in host defense against intracellular pathogens such as c. pneumoniae. c. pneumoniae is a relatively recently recognized pathogen and the cellular mechanisms in c. pneumoniae immunity have so far remained unstudied. the present review includes the data available on c. pneumoniae ...19979259075
epidemic patterns and carriage of chlamydia pneumoniae in norway.chlamydia pneumoniae infection, in earlier days misdiagnosed as ornithosis, is very common in norway. the disease develops slowly, a feature that may account for the very large number of subclinical cases, which may be seven fold more common than clinical cases. subclinical cases produce an antibody response similar to that seen in overt clinical disease. silent carriage of c. pneumoniae in healthy individuals may be frequent. therapy based on positive cell culture or polymerase chain reaction ( ...19979259076
respiratory tract infection due to chlamydia pneumoniae in military personnel.the objective of this investigation was to determine whether chlamydia pneumoniae was involved in an outbreak of respiratory disease among military recruits, 92 patients (average age 20.1 years) were included in the study if they had a sore throat or cough for more than 1 week. in addition to sore throat and cough, fatigue, headache, dyspnoea and vertigo were the most frequent symptoms. the patients received standard treatment with 100 mg of doxycycline b.i.d. for 14 days. in 38.8% of cases symp ...19979259077
respiratory chlamydial infections in a hong kong teaching hospital and association with coronary heart disease.the microimmunofluorescence antibody technique was used to determine the seroprevalence of antibodies to chlamydia pneumoniae and chlamydia psittaci from hospitalized patients in hong kong. antibodies to c. pneumoniae were found in 54.8% of 157 patients hospitalized with respiratory disease, in 71.1% of 83 patients with cardiac disease and in 31.2% of 93 patients without either respiratory or cardiac disease. antibodies to c. psittaci were found in 0.9% of the combined study groups. there was se ...19979259078
chlamydia pneumoniae and chronic lung diseases.chlamydia pneumoniae infection has been implicated in several chronic lung diseases by serology and direct antigen detection. acute lower respiratory tract infection caused by c. pneumoniae seems often to precede attacks of asthma in both children and adults. chlamydia pneumoniae is also involved in some exacerbations of chronic bronchitis and chronic obstructive lung disease but, more importantly, seems to be strongly associated with the latter irrespective of exacerbation status. moreover, per ...19979259079
reinfection with chlamydia pneumoniae may induce isolated and systemic vasculitis in small and large vessels.it is a common clinical experience that the onset of the so called non infectious vasculitides is often preceded by upper respiratory tract symptoms. a specific agent is only occasionally recovered. we report five cases in sweden with manifestations of vasculitis from different organs. in three of the five patients the onset was preceded by upper respiratory tract symptoms. all patients had serologic findings indicating chlamydia pneumoniae infection and all required corticosteroid treatment for ...19979259080
interaction between infection and exercise with special reference to myocarditis and the increased frequency of sudden deaths among young swedish orienteers 1979-92.infection and fever evoke a cytokine-mediated host response resulting in negative nitrogen balance, muscle protein degradation, which includes the skeletal muscles as well as the heart muscle, and deteriorated muscle function. physical training has an opposite effect. moderate physical training also stimulates the immune system, whereas exhaustive and longlasting exercise is followed by a temporary immunodeficiency and an increased susceptibility to respiratory tract infections. exercise in the ...19979259081
chlamydia pneumoniae and myocarditis.sera from 20 male patients with a diagnosis suggestive of myocarditis, perimyocarditis or pericarditis were found significantly more often to have specific iga antibodies to chlamydia pneumoniae than sera from healthy blood donors of the same age and from the same time period. a less pronounced difference in igg titres was found between patients and blood donors, and igm antibodies were found only in one patient. a striking variation over time in the prevalence of specific antibodies to c. pneum ...19979259082
chlamydia pneumoniae and atherosclerosis--an update.the role of chlamydia pneumoniae in atherosclerosis is at present controversial and neglected by researchers studying the pathogenesis of the disease. numerous seroepidemiological studies have shown an association of c. pneumoniae infection with coronary heart disease and recent studies have indicated the ubiquitous presence of c. pneumoniae in the atherosclerotic lesions. the majority of cardiologists are, as yet, more apt to consider the finding of c. pneumoniae in atherosclerotic lesions as b ...19979259083
randomised trial of roxithromycin in non-q-wave coronary syndromes: roxis pilot study. roxis study group.there is serological evidence for an association between chlamydia pneumoniae and coronary heart disease. we investigated the hypothesis that an antichlamydial macrolide antibiotic, roxithromycin, can prevent or reduce recurrent major ischaemic events in patients with unstable angina.19979259655
chronic infections and coronary heart disease: is there a link?a large number of studies have reported on associations of human coronary heart disease (chd) and certain persistent bacterial and viral infections. we review the epidemiological and clinical evidence on chd and helicobacter pylori, chlamydia pneumoniae, and cytomegalovirus (cmv), as well as possible mechanisms. the association between chd and h pylori may be accounted for by residual confounding from risk factors. although the association between c pneumoniae and chd is stronger, the sequence o ...19979259669

antibody response to the 60-kda chlamydial heat-shock protein is associated with scarring trachoma.to determine if serum antibody response to the 60-kda chlamydial heat-shock protein (chsp60) was associated with scarring trachoma, responses to chlamydia trachomatis and to chsp60 from 148 gambian subjects with trachomatous scarring and from 148 controls without clinical evidence of disease from trachoma-endemic communities were characterized. chsp60 response was found in 32% of cases and 16% of controls (p < .001). although c. trachomatis titer was also higher in cases than controls, the preva ...19989419202

failure to detect the presence of chlamydia pneumoniae in sarcoid pathology specimens.the pathogenesis of sarcoidosis is not yet known. on the basis of seroepidemiological data, an association between chlamydia pneumoniae infection and sarcoidosis has been suggested, but so far no study has addressed the direct detection of this agent in the affected tissues. the aim of the present study was to detect c. pneumoniae deoxyribonucleic acid (dna) within sarcoid tissue specimens by means of a two-step polymerase chain reaction. lung biopsy specimens of 33 patients with histologically ...19979426104

susceptibility of chlamydia pneumoniae to azithromycin and doxycycline: methodological aspects on the determination of minimal inhibitory and minimal bactericidal concentrations.an in vitro assay for measuring and comparing the efficacy of different antimicrobial agents against chlamydia pneumoniae was developed. azithromycin, a representative of the new azalide group of antibiotics, and doxycycline were evaluated with respect to their antibacterial effect and capacity for intracellular killing under different experimental conditions. for both study drugs, the minimal inhibitory concentration (mic) and minimal bactericidal concentration (mbc) values increased significan ...19979435043
empirical therapy of community-acquired pneumonia: macrolides are not ideal choices.macrolides are a rational option for patients with community-acquired pneumonia managed as outpatients. for hospitalized patients, they may be used to supplement other drugs, usually betalactams, because of their excellent activity versus legionella, chlamydia pneumoniae, and mycoplasma pneumoniae. the reason for lack of confidence for macrolides as single agents in hospitalized patients, especially for seriously ill patients, is the lack of studies confirming good results for seriously ill pati ...19979436960

influence of viral and bacterial respiratory infections on exacerbations and symptom severity in childhood asthma.the recent development of pcr for the diagnosis of respiratory viral infection has highlighted the importance of these infections in acute exacerbations of asthma. rhinoviruses are important in all age groups, but particularly over 1 yr, while the role of rsv in bronchiolitis and wheezing in infants has been reaffirmed. recent studies using the same technique for the detection of c. pneumoniae suggest a high prevalence of chronic infection in asthmatic children, and that the immune response to t ...19979443219
the association between serum sialic acid and asymptomatic carotid atherosclerosis is not related to antibodies to herpes type viruses or chlamydia pneumoniae. the atherosclerosis risk in communities (aric) study investigators.total serum sialic acid is a recently investigated marker for cardiovascular mortality and carotid atherosclerosis. this study tested the hypothesis that past infection by herpes simplex type 1 or type 2 viruses or cytomegalovirus or chlamydia pneumoniae accounts for the association between serum total sialic acid and atherosclerosis.19979447421
