(Article in Bulgarian, Summary in English, 6 tables, 15 ref.)Veterinarnomeditsinski Nauki, Sofia (Bulgaria); Veterinary Science, 1987, 24(7) 49-59. Observations were made on the hygiene state of the meat-conditioning departments and enterprises of 13 meat-dressing combines. Both qualitative and quantitative investigations were carried out with regard to 9 bacteriologic indexes. The result of studies on a total of 1,042 samples of washings taken from equipment, working tools, machines, working milieu, and hands and aprons of workers prior to beginning work showed that in case all regulations of cleaning, washing, and disinfection were observed the residual microflora, and, more specifically organisms that were of interest from a sanitary point of view were lowered to minimum counts. No pathogenic Staphylococcus and Salmonella organisms were isolated. It was found that during work the count of indicative organisms considerably rose. No patho-genic staphylococci were isolated. In one case only were there Salmonella typhimurium organisms on the surface of a circular saw for carcass cutting. The overall bacteriologic investigation of a total of 137 samples of minced meat and meat balls and other products prepared with such meat revealed that the average counts of various organisms ranged as follows: aerobic mesophiles--3,653 830/g, and coliforms--31,748/g; Escherichia coli organi-sms were demonstrated in 10.22 per cent of the cases, B. proteus--in 1.46 per cent, and pathogenic staphylococci--in 3.65 per cent of the samples. None of the samples, weighing 25 g each showed the presence of Salmonellae. No correlative dependence was found between the coli titer and the coli index of the products.

(Article in Bulgarian, Summary in English, 5 tables, 17 ref.)Veterinarnomeditsinski Nauki, Sofia (Bulgaria); Veterinary Science, 1987, 24(2) 3-11 Calves, aged 20 days, were experimentally infected with Salmonella dublin. The animals of one-group were treated at the rate of 6.10(8), and those of another--at 2.10(10) up to 4.10(10) live bacterial cells. The calves of the first group showed no clear clinical symptoms of a disease; neither did they manifest regular shedding of bacterial cells. The calves of the second group presented a typical clinical picture, with more regular shedding of bacteria through nasal discharges and the feces. After killing the animals Salmonella dublin organisms were found in all parenchymal organs and in the lymph nodes. Morphologically, the prevalence was established of inflammatory necrobiotic processes in the liver, with activation and proliferation of the sinus endothelium of the lymph nodes, and catarrhal inflammation of varying manifestation in the small intestine.
