Eighteen strains of Pseudomonas aeruginosa, i.e. 8.87%, were isolated during a year from 203 samples of raw milk. Two Pseudomonas aeruginosa strains, i.e. 4%, were isolated from 50 samples of pasteurized milk. The strains were isolated using propagation techniques in meat-peptone broth with malachite green and on selective media--on centrimide agar (CEM)(More)
The extent of contamination in slaughtered poultry by strains of Staphylococcus aureus was investigated, as well as the origin of strains and the way of their transfer during operation of the poultry slaughterhouse. 45 strains were isolated from 175 swab samples from the surface and the body cavity of poultry and 8 strains from 23 workers of the(More)
Resistance to selected antibiotics was studied in 325 strains of Staphylococcus aureus, isolated from foodstuffs. Out of these strains, 50.46% were resistant to penicillin, 15.7% to ampicillin, 4% to streptomycin, 5.2% to erythromycin, 5.8% to chloramphenicol, 18.5% to tetracycline, 18.2% to oxytetracycline, 2.5% to gentamycin, 1.6% to canamycin, 53.5% to(More)
Products from liver were studied for the content of lipolytic microorganisms during production and storage. Lipolytic microorganisms were found in all samples of the products. Their occurrence ranged from 10(4) to 10(7) organisms per g. In finished products and in products stored at a refrigerator temperature their numbers were much lower (10-10(4) per g).(More)
Aerobic and/or facultatively anaerobic sporulating Gram-positive bacteria of the genus Bacillus influence nutritive and sensory properties of pasteurized milk by their proteolytic and lipolytic activity. Since particularly raw milk is a source of pasteurized milk contamination by spore-producing bacteria, our investigations were focused on identification of(More)
