[Preliminary investigation of the in vitro inhibitory effect of antibiotics on algae of the genus Prototheca].

We investigated the possible inhibitory action 'in vitro' by antibiotic containing discs against microscopic alga that are potential human pathogens of the genus Prototheca especially P. wickerhamii. The results indicated that inhibitors in vitro included amikacin, colistin, dibecacin, framicetin, gentamycin, kanamycin, lividomycin, neomycin, polymyxin, paromomycin, ribostamycin, sisomycin and tobramycin. We emphasize the interest in the effectiveness at these drugs in a case of human protothecosis.
