ABSTRACT
An investigation of poultry litter intended for use in farm feeds showed that 0,37%, 0,49%, 0,25% and 12,3% of the 813 samples tested were contaminated with Clostridium spp., haemolytic Escherichia coli, Staphylococcus aureus and 21 different species of Salmonella. The findings clearly underline the hygienically dangerous nature of crude poultry litter. The practical implications of the results are briefly discussed, particularly in view of current regulations.

Tests currently in use of the diagnosis of brucellosis and the immune response in cattle following exposure to Brucella antigens are reviewed. The interpretation and evaluation of results obtained by different tests under conditions where S19 vaccine is used, are discussed. Attention is focussed on the possible role of the bull in disseminating Brucella organisms.
