Trichinella spiralis infection in pigs in the Bolivian Altiplano.
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.
