[Mapping method in the epidemiological study of infections and infestations. II. Soil characteristics in localities permanently at risk for anthrax].

Investigations carried out with the use of the mapping method have revealed that the distribution of localities with stationary unfavorable situation in anthrax throughout the area is linked with the agrochemical properties of soils. The number of the foci of anthrax on neutral and weakly alkaline soils has proved to be considerably higher than in soils with low pH values. No relationship between the content of humus in soils and the distribution of localities with stationary unfavorable situation in anthrax throughout the area has been detected.

[Antibiotic sensitivity of bacteria of the family Vibrionaceae isolated from the intestines of swine].

Bacteria of Aeromonas hydrophila subsp., biotype 1 and Aeromonas anaerogenes, biotype 2, as well as Proteolitica of the vibrio pasahumoliticus biotype were isolated from the intestine of pigs with diarrhea. Close antibiotic sensitivity of the isolates was shown.
