Enteroviruses (EVs) are the most common cause of respiratory tract infections in humans and are classified into seven species (EVA-D and rhinovirus [RHV] A-C) with more than 200 different serotypes. Little is known about the role of EVs in respiratory infections in South America. The main objective of this study was to determine the prevalence of EVs in children aged ≤ 15 years with influenza-like illness enrolled in an Influenza and other respiratory viruses’ passive surveillance network in the district of Piura during 2011. Throat swabs and epidemiological data were collected from each participant. Virus isolation was performed by cell culture using four cell lines (LLCMK2, Vero, RD and A549). The identification and serotyping of EV were performed by immunofluorescence assay using monoclonal antibodies. Isolates non-serotypeable by immunofluorescence were selected for analysis by RT-PCR, followed by sequencing. A total of 424 samples were analyzed, and EVs were found in 47 samples (11.1%). 46.8% of these EVs were found in children aged ≤ 1 year. Our results revealed a predominance of EVB species, 62.5%. No EVD isolates were isolated. Fifteen serotypes were identified, 4 EVA, 8 EVB, and 2 EVC species. Moreover, seven samples could not be correctly classified with our methodology. The most common serotypes were coxsackievirus B2, coxsackievirus A2, and echovirus 9. The use of cells RD and A549 increase the isolation of EVs. This study provides data about the serotypes of EVs circulating in the district of Piura and sets the need for further studies. Keywords: Enterovirus, respiratory infections, Piura
