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.

Epidemiology of urinary tract infections caused by extended-spectrum beta-lactamase-producing Escherichia coli.

Objectives: To describe the epidemiology of urinary tract infections caused by extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli.

Methods: We performed three studies: a trend study (1999 to 2004) to assess the evolution and origin of ESBL-producing E. coli isolates from urine samples; a comparison of the susceptibility patterns of ESBL-producing E.
