PURPOSE Kawasaki disease (KD) is the main cause of acquired heart disease in children. In addition to cardiovascular involvement, many complications have been recognized in KD. However, respiratory complications have been rarely reported. We investigated the differences in clinical characteristics, laboratory findings, radiography findings, and echocardiography findings of Mycoplasma pneumoniae...

We determined the age-related prevalence of complement-fixing antibody to Mycoplasma pneumoniae from the computerized laboratory results of our routine diagnostic department. The material consisted of about 58,000 sera from an 8-year period, 1971 to 1978. Among children less than 1 month old, the frequency of complement-fixing antibody of titers greater than or equal to 8 was low (23%), and no ...

Introduction: Cases of pulmonary embolism (PE) concurrent with Mycoplasma pneumoniae infection are rare in the medical literature. We describe a patient with M. pneumoniae bronchiolitis and pneumonia who developed multiple right-sided, subsegmental PE. Case Description: A 54-year-old man presented following one week of respiratory and constitutional symptoms. He was admitted for respiratory dis...

BACKGROUND Although multiple combinations of weather factors may contribute to an increased incidence of Mycoplasma pneumoniae pneumonia, few studies have investigated the association between weather factors and cases of M pneumoniae pneumonia. METHODS Data on cases of M pneumoniae pneumonia and weather factors in Fukuoka, Japan from 1999 to 2007 were obtained and time-series analysis was use...

The ORF6 gene product of Mycoplasma pneumoniae is involved in a yet-unknown manner in the adhesion of the bacterium to its host cell. Part of the ORF6 gene is a repetitive DNA sequence (RepMP5), about 1,900 bp long. Seven additional similar copies of RepMP5 are dispersed on the genome. In the independently isolated strains M. pneumoniae M129 and FH, the RepMP5 copies residing in the ORF6 gene a...

Real-time isothermal nucleic acid sequence-based amplification (RT-NASBA) was applied to the detection of Mycoplasma pneumoniae. In vitro-generated M. pneumoniae RNA was used to assess the sensitivity of the assay. The 95% hit rate was 148 molecules of M. pneumoniae RNA in the amplification and 10(4) molecules of in vitro-generated RNA after nucleic acid extraction. The sensitivity of the RT-NA...

BACKGROUND A stationary association between climate factors and epidemics of Mycoplasma pneumoniae (M. pneumoniae) pneumonia has been widely assumed. However, it is unclear whether elements of the local climate that are relevant to M. pneumoniae pneumonia transmission have stationary signatures of climate factors on their dynamics over different time scales. METHODS We performed a cross-wavel...

An extensive study of the epidemiological and serological characteristics of Mycoplasma pneumoniae infection was carried out in a military population. There was an increase in the infection rate at Camp Lejeune during the summer months as indicated by a relative increase in isolations, seroconversions, and hospitalizations for M. pneumoniae pneumonia. Twenty-three percent of the trainees who la...

BACKGROUND Mycoplasma pneumoniae is thought to be a common cause of respiratory tract infections (RTIs) in children. The diagnosis of M. pneumoniae RTIs currently relies on serological methods and/or the detection of bacterial DNA in the upper respiratory tract (URT). It is conceivable, however, that these diagnostic methods also yield positive results if M. pneumoniae is carried asymptomatical...
