Outbreak of Pseudomonas aeruginosa infections in a neonatal care unit associated with feeding bottles heaters.

This report describes an outbreak caused by Pseudomonas aeruginosa in a neonatal care unit possibly linked to feeding bottles heaters. Infection control measures were undertaken such as reinforcement of contact isolation precautions, environmental microbiologic sampling, educational sessions on hand hygiene, and use of sterilized water to refill feeding bottles heaters. The sustained eradication of P aeruginosa isolates after implementing control measures on feeding bottles heaters strongly suggests those as the source of the outbreak.

[Phenotypes and mechanisms of resistance to macrolides and lincosamides in Streptococcus agalactiae isolates with clinical significance in an eight-year period (2002-2010)].

Introduction: Streptococcus agalactiae is the most prevalent agent of invasive disease in the newborn (sepsis, pneumonia, and meningitis), as well as an important cause of puerperal fever, urinary tract infection and surgical site infection. The aim of our study was to know the evolution of macrolide and lincosamide resistance in this microorganism.

Methods: Resistance phenotypes were established according to the erythromycin-clindamycin induction test: M (efflux pump) or MLSB (methylase).

[Macrolide-resistant Streptococcus pneumoniae on the islands of Gran Canaria and Lanzarote (Spain): molecular mechanisms and serogroup relationships].

Background: Macrolide resistance in Streptococcus pneumoniae is coded by the ermB and mefA/E genes. The aim of this study was to determine the status of macrolide-resistance, the molecular mechanisms involved, the serogroup relationships, and the level of co-resistance in S. pneumoniae isolates from Gran Canaria and Lanzarote, in the Canary Islands, Spain.

[Hepatitis B virus genotypes in chronic carriers on the island of Gran Canaria. Clinical and epidemiological characteristics].

Objective: To investigate the prevalence of hepatitis B virus (HBV) genotypes in Spanish hepatitis B carriers, and to study the differences in epidemiological characteristics, e antigen (HBeAg) seroconversion, serum DNA viral levels (VL) and liver function alterations.

Methods: This study included 108 patients. Genotyping was carried out in 84 with the INNO-LiPA HBV genotyping assay (Innogenetics).
