The in vitro activities of nemonoxacin, levofloxacin, azithromycin, and doxycycline were tested against 10 isolates each of Chlamydia trachomatis and Chlamydia pneumoniae. The MICs at which 90% of the isolates of both C. trachomatis and C. pneumoniae were inhibited (MIC90s) were 0.06 μg/ml (range, 0.03 to 0.13 μg/ml). The minimal bactericidal concentrations at which 90% of the isolates were kil...
Background Reactive arthritis, Reiter’s syndrome is one of the seronegative arthropathies, that can be associated with intestinal infections (Shigella, Salmonella, Yersinia, Campylobacter jejuni, Clostridium difficile), sexual infections (Chlamydia trachomatis, Ureaplasma urealyticum) and lung infections (Chlamydia pneumoniae, Mycoplasma pneumoniae). Reiter’s syndrome is an arthritis that occur...
Chlamydia trachomatis and Chlamydophila pneumoniae are human pathogens; the former being the etiologic agent for trachoma as well as a prevalent sexually transmitted bacterium, while C. pneumoniae is a respiratory pathogen responsible for community-acquired pneumonia. Patients with reactive arthritis show evidence of present or past Chlamydial infection. Chlamydia spp., has been strongly implic...
No analysis has been carried out on the impact of Chlamydia in pediatric patients with arthritis. The present study was conducted to investigate whether Chlamydia trachomatis and Chlamydia pneumoniae could be identified as a triggering infection in 33 pediatric patients including adolescents with acute joint disorders by using an extensive laboratory approach. Synovial fluid, nasopharyngeal sec...
The seroprevalence of Chlamydia pneumoniae and Mycoplasma pneumoniae in hantavirus seronegative patients, who had symptoms and signs compatible with pneumonia was established. For this purpose we used the indirect fluorescent antibody test. Titers > or = 1:16 for C. pneumoniae and M. pneumoniae were found in 8.6% and 17.1% of the serum, respectively, showing evidence of recent or current infect...
BACKGROUND Recent studies have confirmed the presence of viable Chlamydia in the bronchoalveolar lavage (BAL) fluid of pediatric patients with airway hyperresponsiveness. While specific IgG and IgM responses to C. pneumoniae are well described, the response and potential contribution of Ag-specific IgE are not known. The current study sought to determine if infection with Chlamydia triggers the...
The pathogenesis of primary pulmonary hypertension is still unclear. The case of a 68-yr-old female patient who complained of recurrent dizzy spells and collapses over a period of 6 weeks and died of global cardiac failure is presented. Autopsy revealed severe pulmonary hypertension, slight chronic bronchitis, and bronchiolitis as well as intra-alveolar accumulation of macrophages. Chlamydiae w...
OBJECTIVE To examine whether reactive arthritis (ReA) known to occur after a urogenital infection with Chlamydia trachomatis can also follow an infection with Chlamydia pneumoniae, a recently described species of Chlamydiae that is a common cause of respiratory tract infections. METHODS Specific antibodies (microimmunofluorescence test) and lymphocyte proliferation to C trachomatis and C pneu...
There is evidence that infection with Chlamydia pneumoniae is associated with asthma of recent onset and that it can influence the severity of asthma. This has led to the suggestion that macrolide antibiotics may be useful in the treatment of asthma in subjects infected with C. pneumoniae. This study examined the association between immunoglobulin (Ig)G and IgA titres to C. pneumoniae and the s...
Chlamydia pneumoniae and Mycoplasma pneumoniae were evaluated as agents of persistent cough in adolescents and adults (n = 491). Tests of 473 respiratory specimens by culture or PCR or both identified four episodes (0.8%) of M. pneumoniae-associated illness and no episodes of C. pneumoniae illness, suggesting that these bacteria do not frequently cause persistent cough.
