[Isolation of Listeria ivanovii in Slovakia].

From October 1977 to May 15, 1989 in Slovakia 39 strongly haemolytic strains of L. ivanovii were isolated from a woman after delivery of a stillborn foetus--from the lochiae, placenta and rectal smear, from five symptom-free subjects from the faeces, from the rectal smears of two sheep, from the intestinal contents in the portion of the terminal ileus from 28 free living small terrestrial mammals, one strain from meat--beef steak, from the lungs, liver and kidneys of a dead young sheep and one strain from silage. The strains from the lochiae and placenta as well as those from the organs of sheep were detected already as primocultures on commonly used blood agar, the other strains after varying periods of cold enrichment and subsequent inoculation on a solid selective medium with nalidixic acid and acriflavin.

[Use of the hemolytic interaction phenomenon in the typing of Campylobacter sp].

Various identification schemes are used for the typification of the strains of Campylobacter sp.; some of them are based on the evaluation of tolerance to salt, ranging from 0 to 3.5%, others on the evaluation of the temperature ranges (0-45 degrees C), etc.
