OBJECTIVE To report, to our knowledge, the first case of detection of human metapneumovirus in the cerebrospinal fluid of a patient during acute encephalitis. DESIGN Case report. SETTING University hospital. PATIENT A 10-year-old girl with acute encephalitis. RESULTS Human metapneumovirus was detected in cerebrospinal fluid and nasal-wash specimens during the initial phase of mild encep...

human metapneumovirus (hmpv) infection plays an important role in the pediatric respiratory infections. the aim of this study was to determine the relationship between asthma and wheezing with hmpv in hospitalized children. nasal pharyngeal swabs obtained from 120 children aged 1-60 months, hospitalized during a one year period, were tested for the hmpv by rt-pcr. hmpv was detected in 20 (16.6%...

Reverse transcription-polymerase chain reaction was used to detect segments of the M (matrix), N (nucleoprotein), and F (fusion) genes of human metapneumovirus in bronchoalveolar fluid from 30 infants with severe respiratory syncytial virus bronchiolitis. Seventy percent of them were coinfected with metapneumovirus. Such coinfection might be a factor influencing the severity of bronchiolitis.

We describe the prevalence of human metapneumovirus infection in children visiting outpatient department with symptoms of respiratory illness in rural areas of Dibrugarh District of Assam. Human metapneumovirus was observed in 7.2% (20/276) of children aged =5 years with detection of genotypes A2b and B2.

Chimeric versions of recombinant human metapneumovirus (HMPV) were generated by replacing the nucleoprotein (N) or phosphoprotein (P) open reading frame with its counterpart from the closely related avian metapneumovirus (AMPV) subgroup C. In Vero cells, AMPV replicated to an approximately 100-fold-higher titer than HMPV. Surprisingly, the N and P chimeric viruses replicated to a peak titer tha...
