[Preliminary studies of Conus geographus venom structural properties: evaluation of the toxin's molecular weight].

Venom from the posterior half of the venom duct of Conus Geographus was toxic to mice but without effect on a crab, and produced a flaccid spasmodic paralysis in mice. The minimum lethal dose for mice ranged from 5 micrograms to 50 micrograms (net weight) of venom per mouse. Toxin was submitted to Sephadex G 25 chromatography and to ultrafiltration. The venom was inactivated by pronase. The data suggested that the toxin was a peptide of molecular weight of about 1 500-2 000.

[Alteromonas putrefaciens. 25 strains isolated in Madagascar].

25 strains of Alteromonas putrefaciens, most of them from marine medium, isolated in Madagascar, are reported. Biochemical characters are studied to class them in 2 subspecies. Routinely, Alteromonas putrefaciens must be chiefly differentiate with H2S-producing Enterobacteriaceae. The ecology is recapitulated.
