Serotype Prevalence and Penicillin-susceptibility of Streptococcus pneumoniae in Oman.

Objectives: to determine the prevalent serotypes of Streptococcus pneumoniae and the rate of penicillin-nonsusceptibility among pneumococci in Oman.

Methods: Pneumococcal isolates encountered during the period of September 2002 to December 2007 in the Royal Hospital were serotyped. Clinical information as well as the penicillin susceptibility reports were retrieved from the hospital information system and medical records.

Susceptibilities of common bacterial isolates from oman to old and new antibiotics.

Objectives: The purpose of this study is to compare the antimicrobial activity of linezolid and tigecycline with other commonly used antibiotics against a variety of clinical isolates at Royal Hospital, Muscat.

Methods: Clinically-significant bacterial isolates in Royal hospital during the period from 1st of March to 30th of June 2007 were collected, stored and finally tested to determine their susceptibility to different antibiotics by broth microdilution (microscan panels).

Results: Two hundred ten bacterial strains were collected and tested including Staphylococcus aureus (29), Group B ß-haemolytic Streptococcus (10), Streptococcus pneumoniae (15), Enterococcus spp.
