Influence of dietary zinc oxide and copper sulfate on the gastrointestinal ecosystem in newly weaned piglets

Article Abstract:

The effects of elevated dietary doses of ZnO and CuSO4 on the composition and activity of the commensal indigenous microbiota in samples taken from segments representing the entire gastrointestinal tracts of newly weaned piglets is examined. The results suggested that elevated doses of dietary ZnO and CuSO4 reduced the sizes of major groups of bacteria among the porcine gastrointestinal commensals, namely, the lactobacilli and streptococci.

Transmission and infectious dose of Escherichia coli O157:H7 in swine

Article Abstract:

A study hypothesized that Escherichia coli O157:H7 would be transmitted from infected donor pigs to naive pigs at levels that could be sustained in a natural infection and determined the infectious dose. The results suggest that swine do not have an innate resistance to colonization by E. coli O157:H7 and that they could serve as a reservoir host under suitable conditions.

Virulence factor gene profiles of Escherichia coli isolates from clinically healthy pigs

Article Abstract:

A broad variety of virulence gene-positive Escherichia coli (E. coli) isolates were described from swine with no clinical signs of intestinal disease. It was indicated that virulence gene-carrying E. coli strains were a normal part of intestinal bacterial populations and hemolytic activity alone is not clearly associated with the disease.
