The genotoxicity caused by the microcystins LR and LA from a bloom collected in a eutrophic lake, was revealed in the fish Astyanaxbimaculatus, a native species from South America.

Androgenic effects on various fish species have been reported; however, few studies have assessed possible genotoxic effects, although there are concerns about such effects in target and non-target species. We evaluated genotoxic and gonadal effects of MT in adult tilapia (Oreochromis nilotic...

متن کاملSelection of lactobacillus strains for urogenital probiotic applications.
Almost 20 years ago, it was shown that lactobacilli expressed properties that appeared to play a role in protecting the host from urogenital infection [1].

The investigations have focused upon the large clinical problem of lactobacilli depl...
