Recombinant CV-A6 strains related to hand-foot-mouth disease and herpangina at primary care centers (Barcelona, Spain).

To describe the genetic diversity of enteroviruses (EV) causing hand, foot and mouth disease (HFMD) and herpangina, especially of coxsackievirus (CV)-A6, from patients attended at pediatric primary care centers during the 2017-2018 season. Phylogenetic analysis of partial VP1 region was performed for genetic characterization. The complete VP1 and 3Dpol proteins were sequenced for lineage determination and detection of recombination events.

Molecular influenza surveillance at a tertiary university hospital during four consecutive seasons (2012-2016) in Catalonia, Spain.

Background: Influenza viruses (FLUV) are continuously evolving, which explain the occurrence of seasonal influenza epidemics and the need to review the vaccine strain composition annually. The aim is to describe the genetic diversity and clinical outcomes of FLUV detected at a tertiary university hospital in Barcelona (Spain) during the 2012-2016 seasons.

Methods: The detection of FLUV from patients attended at the Emergency Department or admitted to the hospital was performed by either immunofluorescence or PCR-based assays.

Virological surveillance of human respiratory syncytial virus A and B at a tertiary hospital in Catalonia (Spain) during five consecutive seasons (2013-2018).

Aim: Human respiratory syncytial virus (HRSV) is the main cause of respiratory tract infections among infants.

Materials & Methods: In the present study, the molecular epidemiology of HRSV detected from 2013 to 2017 has been described.

Results: A 10% of collected samples were laboratory confirmed for HRSV.

Surveillance of enteroviruses from paediatric patients attended at a tertiary hospital in Catalonia from 2014 to 2017.

Background: Enterovirus (EV) infections are usually asymptomatic or mild, but symptomatic infections can evolve to severe complications. Outbreaks of EV-A71 and EV-D68 have been recently reported worldwide, sometimes related to severe clinical outcomes.

Objective: To describe EV genetic diversity and the clinical outcomes from paediatric patients attended at a tertiary university hospital in Barcelona (Catalonia, Spain) from 2014 to 2017.

Novel tp0548 Sequence-Type of Treponema pallidum Identified in Barcelona, Spain.

A novel tp0548 sequence-type of Treponema pallidum has been identified in a genital ulcer sample collected from a patient diagnosed with primary syphilis at the Hospital Universitari Vall d'Hebron in Barcelona. Following the nomenclature used in the Enhanced Centers for Disease Control and Prevention Typing methodology, letter "z" has been assigned to the new sequence type.
