■ EVIDENCE-BASED ANSWER Erythromycin, clarithromycin, and azithromycin are equally effective in treating pneumonia caused by Mycoplasma pneumoniae or Chlamydophila (formerly Chlamydia) pneumoniae (strength of recommendation [SOR]: B, small head-to-head trials). Macrolide choice can be based on other considerations—cost, side effects, and effectiveness against other suspected pathogens (SOR: C, ...

Chlamydia psittaci is a highly prevalent avian pathogen and the cause of a potentially lethal zoonosis, causing life-threatening pneumonia in humans. We report the genome sequences of C. psittaci 6BC, the prototype strain of the species, and C. psittaci Cal10, a widely used laboratory strain.

Chlamydia suis is a natural pathogen of pigs (Sus scrofa) and causes conjunctivitis, pneumonia, enteritis, and various reproductive disorders that adversely impact this economically important animal. Here, we report the first C. suis genome, that of C. suis MD56, isolated from a conjunctival swab of a weaned piglet.

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...

This is the first documented case of a T-cell lymphoblastic lymphoma arising in the uterus. At presentation, the patient also had a life-threatening pneumonia due to Chlamydia trachomatis which responded to erythromycin and tetracycline. Cytotoxic therapy produced partial tumour regression, but the patient died 14 weeks after diagnosis, probably as a result of intercurrent infection.

Brush biopsies and lung lavages were obtained from 263 individuals with acquired immune deficiency syndrome who collectively had 658 hospitalizations for pneumonia. Chlamydia trachomatis was isolated during three (0.5%) of the episodes, indicating that it was not an important respiratory tract pathogen in this population.

The clinical picture (fever, cough, sputum, auscultatory changes), peripheral blood parameters (leukocytosis, ESR) and radiological data are currently the criteria for suspecting bacterial pneumonia in patients with SARS CoV-2 infection indication of antibacterial treatment. initiation antibiotic therapy is empirical by taking into account pathogens most likely involved community-acquired (Str ...

The most common clinical signs, host responses and radiographic patterns were studied in 203 Italian children hospitalized for community-acquired pneumonia in order to clarify the role of clinical and radiological characteristics in the diagnosis of Mycoplasma pneumoniae and/or Chlamydia pneumoniae infections. Antibody measurements in paired sera and polymerase chain reaction on nasopharyngeal ...

The differential diagnosis of the association of pneumonia and haemorrhagic pericarditis should include viral aetiologies Sir, For the sake of completeness, the differential diagnosis of bacterial pneumonia with haemorrhagic pericarditis 1 should include Chlamydia infection in immunocompetent subjects, 2 and the association of pneumonia and staphylococcal pericarditis. 3 Where a bacterial patho...

Simkania negevensis, a recently discovered Chlamydia-like organism, has been associated with respiratory infections such as pneumonia, bronchiolitis and chronic obstructive pulmonary disease in children and adults. The aim of the present study was to evaluate S. negevensis in the etiology of pediatric community-acquired pneumonia, bronchiolitis and asthma exacerbation in our region. Overall, 10...
