ABSTRACT
Abstract Hantavirus Pulmonary Syndrome (HPS) is an emerging infectious disease of the Americas. Eight native rodent species have been identified as HPS virus reservoirs in Argentina. The aim of this work was to detect the orthohantavirus genotypes present in a rodent commu-nity that inhabits a zone where a fatal HPS case occurred within an endemic locality of Central Argentina. We captured 27 rodents with a trapping effort of 723 trap nights. We detected 14.3% of infected Akodon azarae with the Pergamino genotype. This result expands the known distribution of this orthohantavirus. Although the Pergamino genotype has not been associated with human cases, the information about its distribution is relevant for risk assessment against potential changes in the virus infectivity.
Resumen El síndrome pulmonar por hantavirus (SPH) es una enfermedad infecciosa emergente en América. Ocho especies de roedores nativos han sido identificadas como reservorios del virus causante del SPH en la Argentina. El objetivo de este trabajo fue detectar los genotipos de orthohantavirus presentes en una comunidad de roedores que habita en una zona donde ocurrió un caso fatal de SPH, en una localidad endémica de Argentina central. Se capturaron 27 individuos con un esfuerzo de 723 trampas-noche. Se detectó un 14,3% de Akodon azarae infectados con el genotipo pergamino. Este resultado amplía el conocido rango de distribución de este orthohantavirus. A pesar de que el genotipo pergamino no ha sido asociado con casos humanos hasta el momento, la información sobre su distribución es relevante para analizar el riesgo ante un potencial cambio en la infectividad del virus.
