nonencapsulated, nontypeable hemophilus influenzae (nthi) remains an important cause of acute otitis and respiratory diseases in children and adults. nthi bacteria are one of the major causes of respiratory tract infections, including acute otitis media, cystic fibrosis, and community-acquired pneumonia among children, especially in developing countries. the bacteria can also cause chronic dise...

Seven years after admission to hospital for acute lower respiratory tract infection in infancy 200 children and their matched controls were assessed for respiratory state and epidemiological characteristics. The index group comprised 100 cases where respiratory syncytial virus infection had been responsible for the index illness (group 1) and 100 cases in whom this organism had not been found (...

Background First identified in 2001, human metapneumovirus (hMPV) is a novel pathogen and causative agent of acute respiratory tract infection. Re-infection with hMPV is common, and currently there is no available vaccine against this virus. Two genetic subgroups (A and B) have been identified, both of which can be divided further into at least two distinct sub-lineages. Here we report the resu...

hclamydia pneumoniae is emerging as a frequent ause of respiratory disease in children as well as adults. C. pneumoniae infection in children presents a different set of problems regarding disease presentation and diagnosis compared to adults. Several studies of the role of C. pneumoniae in lower respiratory tract infection in pediatric populations have found evidence of infection in 0 to over ...

The emergence and spread of antimicrobial-resistant bacterial, viral, and fungal pathogens for which diminishing treatment options are available is of major global concern. New viral respiratory tract infections with epidemic potential, such as severe acute respiratory syndrome, swine-origin influenza A H1N1, and Middle East respiratory syndrome coronavirus infection, require development of new...

Background and Aims: The role of BK and JC polyomaviruses (BKV and JCV) in the causation of respiratory disease and the natural route of transmission has not well been established. The aim of study was to determine the prevalence of BK and JC viruses in 280 respiratory samples and evaluate their contribution to respiratory disease. Materials and Methods: PCR was used to screen specimens for BK...

1. Respiratory infection of rabbits with Bacillus bovisepticus (snuffles) is favored by chilling the animals after they have been accustomed to heat. 2. The character of this disease, which occurs frequently in rabbits under natural conditions, makes the application of the experimental results to similar respiratory conditions in man less open to objection than in similar experiments with other...
