Influence of ileo-caecal cannulation and oxytetracycline on ileo-caecal and rectal coliform populations in pigs.

Bottom Line: The diversity of the enteric coliform flora was initially high both in the ileo-caecal ostium and in rectum.As the insertion of ileo-caecal cannulas did not affect the intestinal coliform flora this study gives support to the use of this technique to mirror processes in the small intestine of pigs.Further, the diversity of the enteric coliform flora was unaffected by the parenteral treatment with oxytetracycline.

ABSTRACT
The effect of surgery (insertion of an ileo-caecal cannula) and a subsequent parenteral treatment with oxytetracycline on the ileo-caecal and rectal coliform populations in 7 Swedish Yorkshire castrates were studied. Samples were collected during surgery as well as 3, 7, 14 and 20 days post surgery. The diversity of the enteric coliform flora was initially high both in the ileo-caecal ostium and in rectum. No alteration in the diversity of the enteric coliform flora was observed following surgery and treatment with oxytetracycline. As the insertion of ileo-caecal cannulas did not affect the intestinal coliform flora this study gives support to the use of this technique to mirror processes in the small intestine of pigs. Further, the diversity of the enteric coliform flora was unaffected by the parenteral treatment with oxytetracycline.

Median (a) and mean values with standard error (b) of the diversity of the enteric coliform flora in the ileo-caecal ostium (open squares) and rectum (filled squares) of 7 conventional Yorkshire castrates following insertion of an ileo-ceacal cannula on day 0. To minimise the risk for postoperative infections a single intramuscular injection with a long acting derivate of oxytetracycline was given in connection to surgery. At surgery the pigs were aged 12 weeks.

To minimise the risk for postoperative infections a single intramuscular injection with a long acting derivate of oxytetracycline was given in connection to surgery. At surgery the pigs were aged 12 weeks.

Mentions: The diversity of the coliform populations were studied in 24 isolates per pig and sampling site each day of sampling. In total 1680 isolates were scrutinised. The diversity was high before surgery, both at the ileo-caecal ostium and in rectum (Fig. 1). Following surgery and oxyte-tracycline treatment, no changes in the diversity of the enteric coliform populations were observed in any of the investigated spots (Fig. 1). Further, the diversity of the enteric coliform flora was similar at these sites of sampling (the ileo-caecal ostium and the rectum). Thus, no statistically significant differences within group over time, or between groups at the different sampling occasions were observed.
