Abstract Background In the past few years, Mycoplasma pneumoniae (Shi et al. Lancet 390:946–958, 2017) infection has been reported more in China. However, there are studies on clinical characteristics and prognosis of necrotizing pneumonia (NP) (Griffiths Nature 583:615–619, 2020) caused by different pathogens. Methods A retrospective analysis was performed, including 31 children with a diagnos...

We compared the performances of three recently optimized real-time PCR assays derived from distinct genomic regions of Mycoplasma pneumoniae during an outbreak. Comprehensive evaluation established that a newly described toxin gene represents a superior target for detecting M. pneumoniae DNA in clinical specimens, although use of multiple targets may increase testing confidence.

Pneumonia is one of the most common conditions encountered by primary care providers. Certain organisms cause pneumonia in particular age groups. For example, group B streptococci, Gram-negative bacilli Escherichia coli in particular) and, rarely, Listeria monocytogenes cause pneumonia in neonates. In infants younger than 3 months, group B streptococci and organisms encountered by older childre...

Legionella pneumophila is one of the causative agent of pneumonia in human being. In recent years many reports has been come from different parts of world regarding infectivity of this organism. This disease occurs almost because of contamination of air conditioning systems. For the purpose of assessment of the legionella pneumophila in pneumonic patients, 200 specimen from sputum and tracheo-b...

Pneumonia is a leading cause of hospitalization and mortality worldwide. Despite recognition of the importance of community-acquired pneumonia (CAP) in adults, limited epidemiologic information is available in South Korea. This study aimed to evaluate the disease burden of hospitalized CAP in adults aged ≥19 years and its epidemiologic trend using Health Insurance and Review Assessment (HIRA) d...

Molecular diagnostic techniques, such as polymerase chain reaction (PCR), are promising tools for the rapid etiological diagnosis of pneumonia. PCR offers potential advantages over conventional tests for the detection of Mycoplasma pneumoniae, Legionella species, and Chlamydia pneumoniae. For pneumococcal pneumonia in adults, PCR adds little to existing diagnostic tests and is unable to disting...

Macrolide resistance in Mycoplasma pneumoniae is often found in Asia but is rare elsewhere. We report the emergence of macrolide-resistant M. pneumoniae in Israel and the in vivo evolution of such resistance during the treatment of a 6-year-old boy with pneumonia.

Review of 214 fetal necropsies performed in the department of pathology, University of Aberdeen, showed 40 cases of chorioamnionitis or intrauterine pneumonia, five of which were associated with Streptococcus milleri. In two cases there was good evidence to implicate S milleri as the cause of infected abortion while in the other cases its pathogenic role was less clear.
