[Clinico-endoscopic and morphologic characteristics of patients with Campylobacter infection]. / Kliniko-éndoskopicheskaia i morfologicheskaia kharakteristika bol'nykh kampilobakteriozom.

Bacteriological examination of feces of 120 patients with signs of acute gastroenterocolitis revealed C. jejuni infection in 19 (7 per cent) of them. There was a certain difference between the clinical course of C. jejuni infection and acute dysentery. The endoscopic examination of the large intestine in jejuni infection demonstrated acute hemorrhagic or catarrhal colitis and phenomena of acute exudative inflammation were found during histomorphological study. C. jejuni infection can be diagnosed on the basis of the clinico-epidemiological findings and the results of bacteriological examination of the patients' feces.

[Prostaglandins and cyclic nucleotides in the gastrointestinal form of yersiniosis]. / Prostaglandiny i tsiklicheskie nukleotidy pri gastrointestinal'noi forme iersinioza.

In spite of the resemblance of the clinical picture of gastrointestinal yersiniosis and acute dysentery, material differences underlie the pathogenesis of these diseases. Yersiniosis is marked by the predominance of an increase in the content of PGF2 alpha, whereas acute dysentery by an increase in the content of PGE, which may be accounted for by greater intensity of the allergic manifestations in yersiniosis patients as compared with dysentery. Shigellosis runs its course in the presence of the prevailing influence of the guanylate cyclase system, whereas yersiniosis in that of the adenylate cyclase. This is likely to be related to graver destructive lesions in the colonic mucosa in acute dysentery.
