Determination of vancomycin minimum inhibitory concentration for ceftazidime resistant Streptococcus pneumoniae in Iran.

Background: In the context of growing health concerns over antibiotic resistance, the evaluation of the minimum inhibitory concentration (MIC) of vancomycin for Streptococcus pneumoniae (S. pneumoniae) strains resistant to ceftazidime becomes important for guiding health policy makers. The aim of this study was to determine vancomycin MIC of ceftazidime resistant S.

Serotype distribution and antibiotics susceptibility pattern of Streptococcus pneumonia in Iran.

Background: The development of antibiotic resistance among Streptococcus pneumoniae strains has caused significant health problems worldwide.

Objectives: The aim of this study was to determine antibiotic resistance pattern and serotypes distribution of Streptococcus pneumoniae strains isolated from clinical specimens.

Material And Methods: A total of fifty Streptococcus pneumoniae strains were isolated from Tehran Hospital's laboratory from 2008 to 2012.
