Publicación Acceso abierto Eco-epidemiological analysis of rickettsial seropositivity in rural areas of Colombia: A multilevel approach.(San Francisco, USA: Revista PLoS Neglected Tropical Diseases, 2017., 2019-09-25) Quintero V., Juan C.; Paternina T., Luis E.; Uribe Y., Alexander; Gil, Juliana; Osorio Q., Lisardo; Muskus, Carlos; Hidalgo, Marylin; Cienfuegos G., Astrid V.; Rojas A., CarlosRickettsiosis is a re-emergent infectious disease without epidemiological surveillance in Colombia. This disease is generally undiagnosed and several deadly outbreaks have been reported in the country in the last decade. The aim of this study is to analyze the eco-epidemiological aspects of rickettsial seropositivity in rural areas of Colombia where outbreaks of the disease were previously reported. A cross-sectional study, which included 597 people living in 246 households from nine hamlets in two municipalities of Colombia, was conducted from November 2015 to January 2016. The survey was conducted to collect sociodemographic and household characteristics (exposure) data. Blood samples were collected to determine the rickettsial seropositivity in humans, horses and dogs (IFA, cut-off = 1/128). In addition, infections by rickettsiae were detected in ticks from humans and animals by realtime PCR targeting gltA and ompA genes.Publicación Acceso abierto Nuevos registros de flebotomíneos (Diptera: Psychodidae), con el hallazgo de Lutzomyia longipalpis (Lutz & Neiva, 1912), en los alrededores de la Ciudad de Sincelejo, Colombia.(São Paulo, Brasil:Biota Neotropica, 2009., 2019-10-11) Vivero, Rafael José; Bejarano, Eduar Elías; Pérez Doria, Alveiro; Flórez, Fernando; Estrada, Luis Gregorio; Torres, Carolina; Muskus, CarlosThis is the first report of Lutzomyia longipalpis (Lutz & Neiva, 1912), L. shannoni (Dyar, 1929), L. micropyga (Mangabeira, 1942) and L. atroclavata (Knab, 1913) in the surroundings of an urban settlement in the Caribbean coast. Phlebotomine sandflies were collected by active search using suction devices and mouth aspirators in trees around the city of Sincelejo, the capital of the department of Sucre. Epidemiological importance derived from this finding is discussed due to the vectorial capacity of L. longipalpis, the natural vector of Leishmania infantum Nicolle, 1908 in America.
