[The characteristics of the protectiveness of a preparation of Vibrio cholerae outer membrane based on the data from a study using the ligated intestinal loop].

The study aimed at finding out the antiadhesive capacity of antigenic preparation, earlier obtained from V. cholerae outer membrane and highly effective with respect to cholera infection, was undertaken. The study was made on previously immunized adult rabbits who had been subjected to laparotomy under anesthesia and the ligation of intestinal loops, subsequently inoculated with the broth culture of V.

[The isolation of the morbilli virus from the Baikal seal Phoca sibirica and its preliminary characterization].

A morbillivirus was isolated from the organs of a seal (Phoca sibirica) which had died during 1987-1988 epizootic in Baikal. This Baikal seal morbillivirus (BSM) was adapted to Vero cell cultures in which it induced a cytopathic effect developing to complete destruction of the monolayer. Typing of BSM was done by indirect immunofluorescence test and enzyme immunoassay using antibodies to distemper and measles viruses.

[Experimental anthrax infection in laboratory animals with differing species susceptibility to the causative agent].

In guinea pigs and noninbred white mice, infected subcutaneously with anthrax which resulted in their death, characteristic generalized infection with the hematogenic contamination of their organs and the signs of intoxication and shock could be observed. In inbred white rats (Fisher 344) the invasion and dissemination of B. anthracis are relatively slightly pronounced, the phenomena of intoxication and shock being clearly prevalent.

[Specific intoxication in anthrax infection].

The pathomorphological picture of experimental B. anthracis infection in white rats (strain Fisher-344) essentially corresponds to experimental anthracic intoxication with very moderately pronounced morphological manifestation of B. anthracis invasion.
