Utilization of CHROMagar MRSA in the supervision of the methicillin-resistent Staphylococcus aureus

Methicillin-resistent Staphylococcus aureus (MRSA) is one of the most common pathogen responsible for nosocomial infections. Laboratory diagnosis and assays of antimicrobial susceptibility are basic in controlling and preventing infection by MRSA. Our study was conducted for one year (May 2008-April 2009) on patients hospitalized to monitor the eventual colonization by MRSA.The use of chromogenic agar MRSA allowed us to identify pink-mauve colonies of MRSA within 24 hours and to make a timely e careful diagnosis

Distribution of HCV genotypes in the metropolitan area of Naples

The Hepatitis C virus is characterized by high genomic variability that leads to the identification of six different genotypes and many subtypes. In this work, we show the prevalence of genotypes in patients living in the metropolitan area of Naples collected in one year, analyzing differences in the distribution depending on sex and age groups

Acute Hepatitis HCV genotype 3h: virological baseline characterization and monitoring “On Therapy”

The Hepatitis C viral genome is highly variable and is classified into 6 genotype groups, based on phylogenetic analysis of the genomic sequence. Here we show a case of acute Hepatitis C in which a rare genotype 3h was evidenced by direct RNA sequencing.We confirm that analysis of the early kinetics of HCV RNA during antiviral therapy is an important prognostic parameter, and that a (to-t3)log10HCV RNA value is a strong predictor for Rapid Virological Response (RVR) and End Therapy Response (ETR)

Subacute bacterial endocarditis (SBE) due to Streptococcus gordonii

Endocarditis is an inflammatory state of the endothelium that promotes thrombus formation and tissue damage on the surface of heart valves. Recent studies have reported endocarditis mortality rates ranging from 12% to 46% (2008). The Streptococcus gordonii is a normal inhabitant of the human oral cavity. It is a component of the microbial communities responsible of plaque formation, associated with dental caries and also regarded as the main causative agent in the development of subacute bacterial endocarditis (SBE)
