The human metapneumovirus (HMPV) is responsible for acute respiratory tract infections in young children, elderly patients, and immunocompromised hosts. In this study, we genetically analyzed the circulating HMPV in Central and South America from July 2008 to June 2009 and characterized the strains present in this region. Samples were collected during an(More)
Given that highly active antiretroviral therapy (HAART) has been demonstrated useful to restore immune competence in type-1 human immunodeficiency virus (HIV-1)-infected subjects, we evaluated the specific antibody response to influenza vaccine in a cohort of HIV-1-infected children on HAART so as to analyze the quality of this immune response in patients(More)
BACKGROUND Human Adenoviruses are recognized pathogens, causing a broad spectrum of diseases. Serotype identification is critical for epidemiological surveillance, detection of new strains and understanding of HAdvs pathogenesis. Little data is available about HAdvs subtypes in Latin America. METHODS In this study, we have molecularly characterized 213(More)
BACKGROUND Human parainfluenza viruses (HPIVs) are common viral causes of community-acquired pneumonia, particularly in children. The four types of HPIV have world-wide distribution; however, limited information exists about the epidemiological profile of HPIV in Latin-America. OBJECTIVE Provide epidemiologic and phylogenetic information about HPIVs that(More)
Human rhinoviruses (HRVs) belong to the Picornaviridae family with high similarity to human enteroviruses (HEVs). Limited data is available from Latin America regarding the clinical presentation and strains of these viruses in respiratory disease. We collected nasopharyngeal swabs at clinics located in eight Latin American countries from 3,375 subjects aged(More)
Human metapneumovirus is a newly discovered pathogen associated with respiratory disease and occurring mainly in children. It produces an acute viral respiratory disease picture that varies from mild disease to severe, and which can require strict surveillance in intensive care units. Currently, reverse transcriptase polymerase chain reaction and cell(More)
Human respiratory syncytial virus (HRSV) is a major cause of viral lower respiratory tract infections among infants and young children. HRSV strains vary genetically and antigenically and have been classified into two broad subgroups, A and B (HRSV-A and HRSV-B, respectively). To date, little is known about the circulating strains of HRSV in Latin America.(More)
To determine whether fibroblasts from Blanco Orejinegro cattle, exhibit any level of resistance to infection against vesicular stomatitis virus (VSV) serotypes Indiana (VSV-I) or New Jersey (VSV-NJ), 30 fibroblast cultures were phenotyped to evaluate their resistance/susceptibility. Thirty three % of Blanco Orejinegro fibroblast cultures were classified as(More)
BACKGROUND The city of Medellin in Colombia has almost no documentation of the causes of acute respiratory infections (ARIs). As part of an ongoing collaboration, we conducted an epidemiologic surveillance for influenza and other respiratory viruses. It described the influenza strains that were circulating in the region along with their distribution over(More)
