ALVES, Jainara Cristina dos Santos et al. Isolation and molecular identification of enteroviruses in cases of non-polio acute flaccid paralysis, occurred in Northern Brazil from 1996 to 2006. Rev Pan-Amaz Saude [online]. 2014, vol.5, n.1, pp.35-42. ISSN 2176-6215.

Enteroviruses (EV) of human origin belong to the family Picornaviridae, they have 30 nm in diameter, genome of single-stranded RNA, with fecal-oral transmission and have been related to outbreaks of several diseases of the central nervous system. This study aimed to identify the presence of non-polio enteroviruses (NPEV) isolated from cases of acute flaccid paralysis (AFP). Cell lines Hep-2C and RD that presented cytopathic effect were selected for further molecular tests. The viral RNA was extracted using QIAamp Viral RNA mini kit. Primers 222 and 292, which increased part of the VP1 region of EV genome, were used in the reverse transcription polymerase chain reaction (RT-PCR) technique for molecular virus detection, producing an amplicon of 356 nucleotides. From 1996 to 2006, 538 fecal samples of AFP suspected cases from Northern Brazil were sent to the Instituto Evandro Chagas. Of this total, 78 (14.5%, 78/538) presented cytopathic effect in both cell lines. Thereafter, 51 (65.4%, 51/78) were positive by RT-PCR. EV positive cases were detected in the States of Amazonas (14/51, 27.4%), Amapá (13/51, 25.5%), Pará (11/51, 21.6%), Rondônia (10/51, 19.6%) and Tocantins (3/51, 5.9%). Genomic sequencing identification was performed in 40 samples. Echovirus (20 cases, nine serotypes) and coxsackievirus (ten cases, three serotypes) were the predominant species found. The results of this study corroborate others conducted in Brazil and in the world, and serve as basis for better understanding about molecular epidemiology of EV circulating in the Amazon Region and its connection with several serotypes cases of neurologic diseases.
