[Experimental selection of weakly virulent strains of Aujeszky's disease virus].
An attempt was made to select slightly virulent strains by consecutive passages in cell cultures and use of extreme dilutions applying the temperature test, and initial and final fractions were compared for lethality and pruritus on rabbits and studied by the plate method. Expand
[Physical methods (ultrasound) and disinfecting agents for decontaminating the water in poultry meat processing].
In vitro studies revealed that the use of ultra sound in the decontamination of cooling water and poultry meat surface did not produce the necessary effect and the iodofor preparations inkosan and yomil S as well as the agents chalamide and chloramine added in fixed concentrations to the water in cooling vats were not shown to be able to inactivate Salmonella organisms on the surface of experimentally contaminated poultry carcasses.

[Chemical and microbiological studies of the meat of broilers fed mixed feeds with a bacterial protein supplement].
Considering the content of total nitrogen, fats, and ashes in the poultry meat most expedient was the incorporation of 4 percent single-cell protein in the feed mixtures for broilers. Expand

[Cleansing and disinfecting the skin of calves in veal production].
The skin of the calves for slaughter was found to be strongly contaminated with bacteria and the bathing and the disinfection with a 2 per cent chloramine solution decreased the number of microbes, however, did not fully inactivate bacteria, which contributed to the additional surface contamination of the meat obtained.

Comparative virologic studies were carried out to isolate the virus of Aujesky's disease from meat, viscera, and raw smoked products by the plaque method and found that the modified plaque method proved more suitable as against the other method. Expand

[Comparative studies of methods for the diagnosis of Aujeszkh's disease].
The virologic studies of a total of 383 organs taken from 183 pigs using a rabbit as a test animal and cell cultures of chick embryo fibroblasts and pig kidney revealed that the per cent of theExpand
