Publicación Acceso abierto Comunidad de roedores en el municipio de San Marcos, Sucre, Colombia.(Sincelejo, Colombia: Revista Colombiana de Ciencia Animal - RECIA, 2012., 2019-10-08) Blanco T., Pedro; Corrales A., Homer; Arroyo M., Steven; Pérez J., Julia; Álvarez G., Lercy; Castellar M., AnaísThe aim of this research was to determinate the composition of rodent communities in urban and rural areas from San Marcos, Sucre, Colombia. Rodents were sampled using Sherman traps from December 2007 to July 2009, with a capture effort of 1200 night traps (capture success 12%). A total of 144 rodents were captured, eight species were registered: Mus musculus (60), Zygodontomys brevicauda (44), Rattus rattus (21), Oryzomys azuerensis (10), Oligoryzomys fulvescens (4), Neacomys spinosus (2), Proechiymys cayennensis (2), and Heteromys anomalus (1). The number of murinae rodents was higher in urban habitats, whereas wild rodent species of subfamily Sigmodontinae were dominant in rural areas. In addition, the highest percentage of population consisted of adult males.Publicación Acceso abierto Evidencia serológica de infección por hantavirus (Bunyaviridae: Hantavirus) en roedores del Departamento de Sucre, Colombia.(Bogotá, Colombia: Revista de Salud Pública , 2012., 2019-10-04) Blanco, Pedro; Arroyo, Stiven; Corrales, Homer; Pérez, Julia; Álvarez, Lercy; Castellar, AnaísFor this investigation 144 rodents were captured with Sherman® traps in urban and rural areas of the municipality of San Marcos, from December 2007 to July 2009. Specific IgG antibodies against the Unnamed Virus (VSN) were detected in plasma samples by indirect ELISA. The main objective of this investigation is to determine the frequency of specific antibodies to hantaviruses in rodents of the municipality of San Marcos, department of Sucre.Publicación Acceso abierto Hantavirus (Bunyavirid: Hantavirus) en roedores murinos de Sincelejo, Departamento de Sucre.(Sucre, Colombia: Revista Colombiana de Ciencia Animal - RECIA,2013., 2019-10-03) Blanco T., Corrales A., Homer Pedro; Castellar M., AnaísThe hantaviruses associated to the Sigmodontinae rodents, are emerging pathogens that cause the Cardiopulmonary Syndrome by Hantavirus (HCS) in the Americas. So far, Colombia has not reported confirmed cases of the disease; however, evidence has shown serological exposure to hantavirusin rodents and humans from two departments in the Caribbean Region, and molecular detection of viral genome in tissue samples of rodents in Antioquia. The aim of this research was to determinate the frequency of hantavirus specific antibodies in rodents from Sincelejo City. Animal samplings were performed with Sherman traps from March to July 2009. IgG antibodies against Sin Nombre Virus were detected in plasma by enzyme-linked immunosorbent assay(indirect ELISA). Sixty-one rodents were captured and identified as three speciesthree species, Musmusculus was the most abundant(91.8%). From the total of analyzed animals, only one exemplar, belonging to Rattusrattus specie (seroprevalence 1.64%), was positive to hantavirus. Serologic findings evidenced hantavirus infection among rodents of subfamily Murinae in Colombia. The presence of antibodies against the virus suggests that at least one hantavirus is circulating in rodents from North of Colombia.
