Mycoplasma pneumoniae and Chlamydophila pneumoniae in children with community-acquired pneumonia in Thailand.

Background: The prevalence of community-acquired pneumonia (CAP) caused by atypical pathogens in Thai children is unknown.

Objective: To examine the prevalence of Mycoplasma pneumoniae and Chlamydophila pneumoniae infections in paediatric patients (aged 2-15 years) with CAP in three academic hospitals using standardised laboratory techniques. The characteristics of atypical pneumonia were also compared with other causes of CAP.

Prevalence and clinical features of mycoplasma pneumoniae in Thai children.

Objective: To determine the prevalence and clinical features of mycoplasma pneumoniae in Thai children with community acquired pneumonia (CAP).

Material And Method: Diagnosis of current infection was based on > or = 4 fold rise in antibody sera or persistently high antibody titers together with the presence of mycoplasma DNA in respiratory secretion. The clinical features were compared between children who tested positive for M pneumoniae, and those whose results were negative.

Prevalence and clinical presentations of atypical pathogens infection in community acquired pneumonia in Thailand.

Objectives: To determine the prevalence of atypical pneumonia and clinical presentations in patients with community acquired pneumonia (CAP).

Material And Method: A prospective multi-centered study was performed in patients aged > or = 2 years with the diagnosis of CAP who were treated at seven governmental hospitals in Bangkok from December 2001 to November 2002. The diagnosis of current infection was based on > or = 4 fold rise in antibody sera or persistently high antibody titers together with the presence of DNA of M.

An Asian study on the prevalence of atypical respiratory pathogens in community-acquired pneumonia.

Background: In many parts of Asia, the inaccessibility and high cost of diagnostic tests have hampered the study of community-acquired pneumonia (CAP) caused by atypical respiratory pathogens.

Objective: This surveillance study examined the frequency of infection with Mycoplasma pneumoniae, Chlamydophila pneumoniae, and Legionella pneumophila in 1756 patients presenting with signs and symptoms of CAP at 12 medical centres in Asia, using standardised laboratory techniques and interpretation criteria in all participating centres.

Methods: Diagnosis of current infection was based on significant changes in antibody titer or persisting high antibody titers, together with the presence of bacterial DNA in respiratory secretions, in the case of M.

Wheezing--associated lower respiratory infections in under 5-year-old children: study in Takhli District Hospital.

Wheezing was detected in 251 of the 421 (59.6%) children under 5 years old suffering from acute lower respiratory infections (LRI) treated at the Takhli Hospital, Nakhon Sawan Province from November 1998 to October 2000. Bronchitis and pneumonia accounted for 55.
