RESUMENA new group of RNA virus was described in 1988 by Pereira. This group of viruses has only two segments of RNA; it was called Picobinavirus (PBV). Since then, it has been reported in animals and humans in several countries, but not in Mexico. In this paper the finding of these viruses in Merida, Mexico is reported. Faecal specimens were obtained from two hundred and eighty nine pigs with diarrhoea during their first month of life. Stools were analyzed by polyacrylamide gel electrophoresis (PAGE). Seventy four pigs showed electrophoretic pattern for rotavirus, whereas only three showed a typical electrophoretic pattern for PBV. Characterization of the strains showed segment sizes which ranged from 2600-1600 bp. The nucleic acid was shown double-stranded RNA by nuclease digestion. This pattern resembles PBV. These findings suggest that PBV could be a new group of virus associated with gastroenteritis in pigs.
