Prevalence of Muscular Sarcosporidiosis in Slaughtered Domestic Pigs in Perak, Peninsular Malaysia.

Abstract

Sarcosporidiosis is a disease caused by intracellular protozoan parasites, namely, Sarcocystis spp. In pigs, three species of Sarcocystis spp. have been recognised, including Sarcocystis meischeriana, Sarcocystis porcifelis and Sarcocystis suihominis. The aim of this study is to determine the prevalence of muscular sarcosporidiosis in pigs using the pepsin digestion technique. A total of 150 fresh heart, oesophagus and thigh muscle samples from 50 Yorkshire and Landrace pigs were collected from two local abattoirs in Perak from May to August 2014. All the fresh muscle samples were thoroughly examined for macrocyst-forming Sarcocystis spp. and processed using the peptic digestion technique to detect bradyzoites. The results from the muscle samples showed that 58% (29 out of 50) of the pigs were positive for Sarcocystis spp. These findings highlight the importance of implementing stringent measures for screening pigs in abattoirs for Sarcocystis spp. infection because this infection in pigs is a public health concern.
