[Clinico-morphological criteria of diagnosis of dysentery and Salmonella infections].

Clinical symptoms and laboratory findings have been evaluated for 108 patients with intestinal infection associated with apparent colitic syndrome. Differential diagnosis between dysentery and salmonellosis was not an easy task even though clinical signs of the diseases appeared different. Dysentery ran with tenesmus, sigmoid pain and spasms. Symptoms of gastritis, intoxication, dehydration, hepatomegaly predominated in salmonellosis. In obscure cases colonic biopsy can be helpful due to high sensitivity of immunofluorescence in histological sections. Morphological diagnostic criteria comprise intensive microbial invasion, pronounced immunomorphological reaction in superficial epithelium of the colon for dysentery and macrophagal affection of the colonic mucosa plate for salmonellosis.
