Geographical and Temporal Structures of Legionella pneumophila Sequence Types in Comunitat Valenciana (Spain), 1998 to 2013.

Legionella pneumophila is an accidental human pathogen associated with aerosol formation in water-related sources. High recombination rates make Legionella populations genetically diverse, and nearly 2,000 different sequence types (STs) have been described to date for this environmental pathogen. The spatial distribution of STs is extremely heterogeneous, with some variants being present worldwide and others being detected at only a local scale.

Screening for subclinical Leishmania infection in HIV-infected patients living in eastern Spain.

Background: We anticipated that patients with HIV infection living in endemic areas were at greater risk of infection which can reactivate due to immunosuppression; therefore, we analyzed the prevalence of latent Leishmania infantum infection in patients infected with HIV.

Methods: A total of 179 patients with HIV infection were screened for the presence of anti-Leishmania antibodies using indirect immunofluorescent antibody test (IFAT) (Leishmania-spot IF; bioMérieux, Marcy l'Etoile, France). All patients were followed up for at least 1 year.
