[Seroprevalence of hepatitis E virus in patients with hepatitis C and / or infected with HIV].

Introduction: Hepatitis E virus (HEV) can cause chronic infection and cirrhosis. The seroprevalence data of anti-HEV IgG in the patients infected with HIV or with chronic liver disease are scarce.

Methods: To document the seroprevalence of HEV infection in HIV patients or with chronic liver disease population, a retrospective study in serum samples from 625 patients was carried on: 200 HIV infected, 200 HCV infected, 25 coinfected by HIV and HCV and 200 healthy controls.

Vitek MS matrix-assisted laser desorption ionization-time of flight mass spectrometry for identifying respiratory bacterial pathogens: a fast and efficient method.

Mass spectrometry has become a reference resource for identifying microorganisms in clinical microbiology services. One hundred and fifty one clinical isolates were selected from respiratory specimens routinely identified as Streptococcus pneumoniae (43), Haemophilus influenzae (64) and Moraxella catarrhalis (44). These identifications were compared with other phenotypical methods and mass spectrometry (MALDI-TOF-MS Vitek).
