The aim of the present work was to study the influence of different dose of parenteral administration selenium and vitamin E in dairy cows prior to parturition on selected metabolic parameters and colostrum quality. A total of 19 dairy cows from a farm with selenium deficiency were included in the study. The cows were divided in 3 groups (C, E1, and E2). In group E1 a product containing selenium and vitamin E (Selevit inj. a.u.v.) was administered IM four weeks prior to the expected date of parturition. In group E2 the same product was administered twice, eight and four weeks prior to parturition. Group C consisted of control animals to which no product...

In vitro tests were used to evaluate bactericidal efficacy of two disinfectants on the basis of peroxygen compounds against one type strain and one field isolate of B. hyodysenteriae. Mean bactericidal concentrations (MBCs) of the two products ascertained with and without the load of organic matter of sterile pig faeces were several times lower than the recommended application concentrations. Bactericidal efficacy of an extract of citric seeds (feed supplement) against type strains of B. hyodysenteriae and B. pilosicoli, with six field isolates of B. hyodysenteriae and three field isolates of B. pilosicoli...

Mycobacterial catalases, peroxidases, and superoxide dismutases and their effects on virulence and isoniazid-susceptibility in mycobacteria - a review

Mycobacteria are intracellular bacterial parasites which survive and proliferate inside of macrophages for long periods of time. Because mycobacterial survival in macrophages is required for virulence, a great deal of effort has been focused on identifying the genetic and physiologic determinants of intracellular survival and growth. A number of factors, among them catalases, peroxidases, and superoxide dismutase have been suggested as agents permitting mycobacteria to overcome the intracellular defences of macrophages. The characteristic features of mycobacterial catalase/peroxidases and superoxide dismutase, their distribution within the genus...

A review of rabies elimination in Europe

The rabies situation has changed drastically in all European countries where oral vaccination campaigns of red foxes against rabies have been implemented. All types of oral vaccines used have shown to be highly efficacious, enabling rabies elimination over large areas. Several countries are already declared rabies-free according to the internationally conditions set and other countries are in the final stage of this process. In this review, the rabies situation in a number of selected European countries is described, with special emphasis on oral vaccination.
