Proceedings: Antibiotic resistance in coliforms from animal feeding stuffs.
D. H. M. JOYNSON AND C. H. L. HOWELLS (Public Health Laboratory, University Hospital of Wales, Cardiff) Samples of animal feeding stuffs were examined for the presence of Gram-negative, lactosefermenting organisms (hereafter called coliforms) and the antibiotic resistance of any strain isolated was determined. Coliforms were found in 13% of all the feeds examined and of these organisms 64-4% we...

متن کاملAnimal Behaviour: Feeding the Superorganism
Insect societies are often described as superorganisms, and there are many functional parallels between organisms and superorganisms. Elegant work using ants shows that nutrient regulation, which occurs in many non-social animals, can also occur at the colony-level.
متن کاملEpidemiological methods for investigating wild animal reservoirs of animal disease.
The epidemiological and ecological methodologies used to investigate tuberculosis in badgers (Meles meles) in Great Britain are reviewed. The objectives of these studies have been, on the one hand, to investigate the causal association between Mycobacterium bovis infection in badgers and the occurrence of tuberculosis in cattle and, on the other, to acquire knowledge of the population biology o...
