[Activity of various enzymes of the intestinal mucosa in spontaneous colibacteriosis in pigs].

The aim of this work was to find out the histochemical activity of alkaline and acid phosphatases, and nonspecific esterases in intestinal mucosa in spontaneous swine colibacillosis. The investigated animals were divided into 3 groups: I--oedema disease (12 pigs), II--enetrotoxemia due to E. coli (8 pigs), III--control animals (5 pigs). The above grouping was based on the clinical, bacteriological and post-mortem examination. A slight increase of alkaline phosphatase activity in the jejunum and ileum of sick pigs was observed. The acid phosphatase activity decreased in the duodenum of oedema diseased pigs, while it increased in the cecum and colon--comparing with the control and enterotoxemia groups of animals. The decrease of acid phosphatase activity was observed in the jejunum and ileum of the enterotoxemia group of animals. The difference in the activity of nonspecific esterases concerned only the cecum and colon of diseased pigs, where its decrease was observed.
