Background: Blood donors positive only for anti-HBc may have a resolved hepatitis B virus (HBV) infection, low grade chronic infection or infection with variant strains of HBV. We aimed to assess the significance of this serological pattern after hepatitis B vaccination in such cases.
Materials And Methods: Twenty-four anti-HBc only blood donors were vaccinated with the Engerix HBV vaccine and a serological and virological evaluation was performed before HBV vaccination and 7-10 days after each dose.
Purpose: To describe the epidemiological cases and microbiological profile of Streptococcus agalactiae serotypes isolated from infected newborns of a Women's Health Reference Centre of Campinas, São Paulo, Brazil.
Methods: Cross-sectional laboratory survey conducted from January 2007 to December 2011. The newborns' strains, isolated from blood and cerebrospinal fluid samples, were screened by hemolysis on blood ágar plates, Gram stain, catalase test, CAMP test, hippurate hydrolysis or by microbiological automation: Vitek 2 BioMerieux®.
Bartonella henselae is the agent of cat scratch disease and bacillary angiomatosis. Blood donors can be asymptomatic carriers of B. henselae and the risk for transmission by transfusion should be considered.

We carried out a microbiological surveillance of bacterial contamination of apheresis platelet concentrates by studying microbial flora on donors' arms before and after skin disinfection, through blood cultures with the diversion volume and with the PC.
Materials And Methods: Platelet aphereses were carried out using two Haemonetics MCS+ instruments.
