title: Trichinella spiralis infection in pigs in the Bolivian Altiplano.
abstract: Trichinella spiralis infection has been reported sporadically in several areas in Central and South America. However, several countries, including Bolivia, have not reported trichinellosis in animals or humans. A small survey of pigs slaughtered in an abattoir in Bolivia was undertaken during September 1991, to determine the presence of Trichinella spiralis. In a group of 100 pigs slaughtered consecutively on a single day and tested using the pooled digestion method, two of eight pools (25%) were positive. Twenty-one of 188 pigs (11.2%) from ten communities slaughtered consecutively on a second day tested positive for the presence of antibodies to Trichinella spiralis using an enzyme-linked immunosorbent assay. It was concluded that trichinellosis is present in pigs in Bolivia and the rate of infection may be quite high.
