The atypical respiratory bacterial pathogens Mycoplasma pneumoniae, Chlamydia pneumoniae and Legionella pneumophila are now recognised as a significant cause of acute respiratory-tract infections, but they remain colourless after Gram-staining and are difficult to identify by conventional bacterial culture tests. It is reported that patients with atypical pneumonia were more likely to have norm...

Stevens-Johnson syndrome is characterized by generalized exanthema associated with high fever, catarrhal symptoms and mucositis. Various etiologies have been implicated, particularly numerous medications and certain agents of atypical pneumonia. Stevens-Johnson syndrome leads to death in up to 5% of cases. We describe the case of a 30-year-old woman with bilateral atypical pneumonia accompanied...

Mycoplasma hyopneumoniae is the etiologic agent of swine enzootic pneumonia. However other mycoplasma species and secondary bacteria are found as inhabitants of the swine respiratory tract, which can be also related to disease. In the present study we have performed a total DNA metagenomic analysis from the lungs of pigs kept in a field condition, with suggestive signals of enzootic pneumonia a...

The incidence of community-acquired pneumonia due to Chlamydia pneumoniae was evaluated in a 1-year prospective study of 236 hospitalized patients with 237 manifestations of pneumonia. The microbiological diagnosis was based on results of cultures of blood and sputum or bronchoalveolar lavage fluid and results of complement fixation tests and indirect immunofluorescence of acute- and convalesce...

Pneumonia is the cause of significant morbidity and mortality especially in developing countries. The frequency and importance of emerging new pathogens have significant implications for therapy. We report a case of pneumonia caused by a very rare organism, Achromobacter denitrificans which was treated successfully with intravenous meropenem injections for 14 days. Review of available literatur...

Mycoplasma pneumoniae, which causes mycoplasmal pneumonia in human, mainly causes pneumonia in children, although it occasionally causes disease in infants and geriatrics. Some pathogenic factors produced by M. pneumoniae, such as hydrogen peroxide and Community-Acquired Respiratory Distress Syndrome (CARDS) toxin have been well studied. However, these factors alone cannot explain this predilec...

Studies focused on the pathological-radiological correlation of human Mycoplasma (M) pneumoniae pneumonia have rarely been reported. Therefore, we extensively reviewed the literature regarding pathological and radiological studies of Mycoplasma pneumonia, and compared findings between open lung biopsy specimen and computed tomography (CT). Major three correlations were summarized. (1) Peribronc...
