Prevalence and risk factors of hepatitis B and C virus infections among the general population and blood donors in Morocco.

Background: Viral hepatitis is a serious public health problem affecting billions of people globally. Limited information is available on this issue in Morocco. This cross-sectional study was undertaken with the aim of determining the seroprevalence and risk factors of hepatitis B virus (HBV) and hepatitis C virus (HCV) among the general population and among blood donors.

Characterization of fusidic acid-resistant Staphylococcus aureus isolates in the community of Casablanca (Morocco).

Resistance to fusidic acid in Staphylococcus aureus is caused by mutation of the elongation factor G (EF-G) encoded by fusA or by expression of a protein, encoded by fusB or fusC, that protects the drug target. Other mechanisms involved in this resistance are mutations in the riboprotein L6 operon within rplF. The aim of this study was to determine the prevalence and mechanisms of resistance to fusidic acid in clinical isolates of S.

Emergence of extended-spectrum beta-lactamases-producing Escherichia coli in community-acquired urinary infections in Casablanca, Morocco.

Introduction: Extended-spectrum beta-lactamase- (ESBL)-producing Escherichia coli are an increasingly significant cause of community-acquired infection worldwide. The aim of this study was to assess the prevalence of ESBL-producing E. coli in a community, to analyze the relationship between strains studied, and to characterize the ESBL genes involved in this resistance.
