Bacillus thuringiensis improved isolation methodology from soil samples.

Bacillus thuringiensis is a sporulating bacterium, which produces parasporal inclusions toxic to insects. Widely used methodologies to isolate Bt from soil consist of a thermal shock treatment followed by selective germination of spores. The results presented here suggest that a preliminary 5 h dry-heat treatment largely enhance the selectivity of these procedures.

[Considerations on the establishment of a computer center for use at hyperbaric medicine centers]. / Considerazioni sull'impianto di un centro di calcolo per le esigenze dei centri di medicina iperbarica.

The advantages and prospects deriving from the establishment of a special computer centre to serve hyperbaric medicine centres are described. Improved management of hyperbaric chambers, the availability of a data bank, the assistance to medical biological and bio-engineering research are only some of the fundamental benefits to be derived from such a centre.
