Type 1 pili (F1) of porcine enterotoxigenic Escherichia coli: vaccine trial and tests for production in the small intestine during disease.

This study was performed to determine whether the F1 (type 1) pili of a porcine strain of enterotoxigenic Escherichia coli are protective antigens and whether they are produced in the pig small intestine during disease caused by an enterotoxigenic E. coli. Reciprocal cross-absorption experiments with antisera prepared against F1 pili purified from enterotoxigenic E. coli 431 (O101:K30,99:H-:F1) and P14 (O149:K91,88ac:8H+:F1) demonstrated that the F1 antigens of the two strains were closely related or identical. Pregnant swine vaccinated with a vaccine prepared from strain P14 (F1+) responded with a significant increase in antibody against F1 in their serum and colostrum. However, the vaccinated dams did not significantly protect their suckling pigs against fatal challenge with strain 431. There was no evidence of F1 pilus production in the strain 431-infected pigs, as determined by immunofluorescent staining of ileal sections, direct electron microscopic examination of bacteria from ilea, and titration of serum agglutinins in convalescent pigs. It was concluded that strain 431 did not produce F1 in the small intestine during disease and that F1 was not a protective antigen in this system.

The evaluation of a new standard data set on reported cases of intestinal infectious disease in Scotland, and recommendations for the future.

A national survey of local authorities was carried out to ascertain what information they collected on reported cases of intestinal infectious disease and why. As a result of the survey, and a review of national objectives, two data collection forms designed to satisfy both local and national objectives were piloted. One of the forms was four pages long, and sought much less data than the second form, which was 10 pages long. The outcomes of these investigations were established, and assessed, to see if they could have led to the achievement of the stated local and national objectives. Neither data collection form was entirely successful in fulfilling all local objectives, although the four-page form was no less successful than the ten page form. Neither form succeeded in fulfilling national objectives. The study has shown that our best efforts at fulfilling local and national objectives by the universal administration of either the four-page, or the 10-page form are of limited value. We recommend that the universal collection of such information from reported cases of intestinal infectious disease be discontinued. We recommend a risk-based approach to identify cases whose follow up is more likely to achieve more realistic objectives.

[Water and intestinal parasitic diseases].

The paper presents data on the rates of Lamblia cyst dissemination of surface water sources in foreign countries, the Russian Federation, Moscow, and the Moscow Region. It shows a role of drinking water in the spread of intestinal parasitic diseases. In accordance with parasitological parameters, specific data on improvement of methodological control of water quality are presented. The dosages of ultraviolet radiation are given in relation to water decontamination of parasitic disease germs.

[Evaluation of pindolol absorption in malabsorption syndromes].

Reports on drug absorption in intestinal diseases are scarce. To investigate pindolol absorption, a drug particularly well absorbed and with low hepatic extraction, plasma concentrations and 54-h urinary excretion (after both oral and intravenous dose) were studied in 6 healthy volunteers and 13 patients with intestinal malabsorption (coeliac disease 5 cases, short bowel syndrome 8 cases) after an overnight fasting. Pindolol plasma concentrations were almost identical after a single intravenous dose in both patients and controls. Again mean blood levels after an unique oral dose were not significantly different between the two groups. However, absorption was slow and/or delayed in eight out of thirteen patients and overall absorption was decreased in two of them. These abnormalities might be related to the diseased intestine, since plasma concentrations and urinary excretion following intravenous administration were quite similar to those observed in volunteers. Nevertheless, results were not related to the extent of the intestinal disease nor the degree of impairment of small intestinal function.

[The functional activity of the thrombocytes in chronic diseases of the large intestine].

Chronic diseases of the large intestine--catarrhal colitis, colonic stasis, unspecific ulcerative colitis, and amebiasis of the large intestine are attended by marked changes in the functional activity of blood platelets and factors of its regulation. They reflect the dynamics of the disease before and after operative and nonoperative treatment. A recurrence of the disease is linked with activation of blood platelets. Trental and contrycal are used for correction of the disorders, which improves the condition of some of the patients. The authors discuss the importance of biogenic amines, cAMP, and functional activity of the blood platelets as universal mechanisms of the development of chronic diseases of the large intestine.

Panfibrinonecrotic colitis in a dog treated by subtotal colectomy.

A dog with signs of small intestinal disease developed signs of severe large intestinal disease after being treated with multiple agents. Endoscopy and biopsy revealed total destruction of the colonic mucosa, which necessitated total parenteral nutrition plus subtotal colectomy. It was hypothesized that the multiple prior treatments led to an overgrowth of toxigenic or cytotoxic bacteria, which caused this colonic mucosal destruction.

Analysis of gamma delta V region usage in normal and diseased human intestinal biopsies and peripheral blood by polymerase chain reaction (PCR) and flow cytometry.

The intestinal population of gamma delta T cell receptor (TCR)-bearing cells was characterized with regard to V delta and V gamma subtype expression. For this purpose, we utilized V gene-specific PCR of mRNA prepared from intestinal biopsies. Predominant expression of the V delta 1 subtype was demonstrated in the small intestine of patients with coeliac disease and in the inflamed colon of patients with inflammatory bowel diseases (IBD: ulcerative colitis and Crohn's disease) as well as in colon biopsies taken from macroscopically normal areas of colon. Although intestinal gamma delta T cells preferentially expressed V delta 1, other V delta transcripts could be detected, of which V delta 2 and V delta 5 were commonly expressed. Analysis of biopsies from mesenteric lymph nodes demonstrated a V delta repertoire similar to the mucosa. In peripheral blood on the other hand, high expression of both V delta 2 and V delta 1 was found. The predominant expression of V delta 1 transcripts in the intestinal mucosa of IBD patients correlated well with protein cell surface expression as analysed by flow cytometry using V delta 1- and V delta 2-specific antibodies. Selective expansion of gamma delta T cells could not be demonstrated within the inflamed mucosa as shown by mRNA analysis and flow cytometry. Instead, IBD patients demonstrated a decreased proportion of TCR gamma delta-carrying T cells in the inflamed mucosa compared with macroscopically normal area of colon. On the other hand, a significantly increased percentage of T cells bearing the gamma delta TCR was found in peripheral blood of patients with Crohn's disease compared with healthy individuals, indicating that local mucosal inflammation may influence the circulating gamma delta T cell population.

[Research on intestinal parasitic diseases in dogs of the city of Rome].

A survey on the diffusion of intestinal parasites of dogs in the town of Rome. The results of a survey on the diffusion of cestodes and nematodes in a hundred dogs in Rome are reported. The dogs were subjected to fecal examinations --- using both the flottation method and the McMaster method -- and to the post-mortem examination of the intestine. At post-mortem examination 25 dogs were found parasitized by one or more species of nematodes, 19 by one or more species of cestodes and 12 both by cestodes and nematodes for a total of 56 animals parasitized. The parasites were identifed with the following frequency: Dipylidium caninum 28 per cent, Toxocara canis 17 per cent, Uncinaria stenocephala 15 per cent, Trichuris vulpis 10 per cent, Toxascaris leonina 9 per cent, Taenia pisiformis 4 per cent, Echinococcus granulosus 2 per cent, Ancylostoma caninum, T. hydatigena and Mesocestoides lineatus 1 per cent each. The most frequent parasite found in stray dogs was U. stenocephala (33.3 per cent) while among the dogs with owners the most frequent one was D. caninum (31.8 per cent) which was also identified most frequently in dogs over a year of age (31.1 per cent). The dogs under one year of age were more often affected by T. canis (43.7 per cent). In the paper a review of similar Italian surveys is also given.

Increased respiratory burst of leukocytes in inflammatory bowel diseases--the analysis of free radical generation by using chemiluminescence probe.

Respiratory burst of leukocytes was determined in Crohn's disease, intestinal Behçet's disease and ulcerative colitis by using chemiluminescence assay. Oxygen-derived free radicals of monocytes in Crohn's disease and those of polymorphonuclear leukocytes in intestinal Behçet's disease were significantly raised as compared with those of controls. In ulcerative colitis, respiratory burst activities of both polymorphonuclear leukocytes and monocytes were found to be highly associated with the disease activities. These results suggest that active oxygen species from leukocytes may participate in the formation of intestinal mucosal lesions in inflammatory bowel diseases via auto-oxidative process.
