The presence of parasites and bacteria was controlled in mice maintained in open conventional conditions. Moreover, an enzyme-linked immunosorbent assay (ELISA) was applied for the detection of antibodies to Mycoplasma pulmonis and to viral infections (Ectromelia virus and Sendai virus) in the sera of these mice. For ELISA tests the kits offered by University Hospital Nijmegen, the Netherlands, were used. Forty mice were controlled bacteriologically and 39 mice parasitologically. The ELISA test for the presence of Ectromelia virus was performed with 15 sera, for Sendai virus - with 27 sera and for Mycoplasma pulmonis with 12 sera. The results obtained allowed us to conclude that laboratory mice bred in open conventional conditions at the Cancer Center in Warsaw can be classified as CV-II (Conventional-II).
Zgodnie z decyzją Komisji WE nr 2001/471/WE z 8 czerwca 2001 r., kierownicy zakładów mięsnych są zobowiązani do regularnych kontroli ogólnych warunków higienicznych produkcji, w tym także higieny procesu uboju. Można to wykonać m.in. badając jakość mikrobiologiczną tusz. W artykule przedstawiono krótki opis metody oraz wyniki jakości mikrobiologicznej tusz wieprzowych na podstawie wyników z 13 ubojni w woj. kujawsko-pomorskim w powiązaniu ze stosowaną technologią uboju świń. Oznaczanie liczby drobnoustrojów na tuszach może być jednym z kryteriów oceny higieny uboju, i - co ważne - jednym z elementów weryfikacji systemu HACCP w procesie uboju zwierząt rzeźnych.

Pursuant to decision of European Community Committee 2001/471/EC of 8 June 2001 meat plant managers are obliged to control regularly general hygienic conditions of production, including the slaughter process hygiene. It can be done i.e. by microbiological quality tests of carcasses. The study presents a short description of the method as well as results of microbiological quality tests of carcasses on the basis of the results from 13 abattoirs in the Kujawy and Pomorze Provina, in connection with the used technology of pigs slaughter. Marking bacterial counts in carcass may be a criterion of slaughter hygiene assessment, and what is important, one of the elements verifying HACCP system in the process of slaughter of slaughter animals.
In recent years an increasing interest in biological plant protection methods is being observed. The reason for developing biological control methods is the occurrence of resistance of pests to chemical pesticides, which induces the ecological danger for natural environment. In view of current achievements and development perspectives for biopesticides usage in plant protection the results regarding the antagonistic activity of microorganisms isolated from several insect species strains against bacterial and fungal pathogens are discussed.
