Abstract
All the serotypes of E. coli were enter pathogenic. Serotypes 0117 and 0147 were found to be more enter pathogenic than other serotypes of E. coll. This was further confirmed with histopathological changes observed in the sections of intestinal loops. Both the serotypes 0117 and 0147 showed extensive loss of intestinal villi, leaving behind a few villi, the height of which were greatly reduced. They also caused wide spread of hemorrhage in subserosal area and lamina proprias.
Serotypes 06, 07, 065, 0117 and 0147 were also enter toxigenic as revealed by rabbit 11eal loop and suckling infant mice tests and finally confirmed with histopathological changes in the intestinal loops.
It was concluded that while studying enter pathogenicity/ enterotaxigenicity of the isolates of E. coli. Consideration of the results of histopathological changes in the intestinal loops of animal model is also essential at least for those loops showing dilatation index less than 0.40.
The presence of enter pathogenic/ enter toxigenic serotypes of coli in pork luncheon meat is alarming From public health point of view, it is important that measures must be taken to prevent contamination of this "ready-to-eat" pork product during its manufacture at different states of production.
