microbiology of acute and chronic sinusitis in children and adults. | the microbiology of infections of the paranasal sinuses can be anticipated according to the patient's age, clinical presentation, and immunocompetence. in acute sinus disease, viral upper respiratory infections frequently precede bacterial superinfection by streptococcus pneumoniae, haemophilus influenzae, and moraxella catarrhalis. staphylococci and respiratory anaerobes are common in chronic sinus infection, which may also be caused by exacerbations of infection with the bacterial species that ... | 1998 | 9671039 |
relatedness of cytotoxins from geographically diverse isolates of moraxella bovis. | to determine whether amino acid sequence variation exists in the moraxella bovis (m. bovis) cytotoxin (mbxa) from geographically diverse m. bovis isolated in the united states, mbxa was amplified and sequenced. the mbxa deduced amino acid sequence from m. bovis originally isolated in california, washington, north carolina, and georgia, as well as reference strains of m. bovis isolated at the national animal disease laboratory, ames, ia, usa, all encoded a nearly identical 927 amino acid protein. ... | 2007 | 17540518 |
