| Nutrition in the Teredinidae family of wood-boring mollusks is sustained by cellulolytic/nitrogen fixing symbiotic bacteria of the Teredinibacter clade. The mangrove Teredinidae Neoteredo reynei is popularly used in the treatment of infectious diseases in the north of Brazil. In the present work, the symbionts of N. reynei, which are strictly confined to the host's gills, were conclusively identified as Teredinibacter turnerae. Symbiont variants obtained in vitro were able to grow using casein as the sole carbon/nitrogen source and under reduced concentrations of NaCl. Furthermore, cellulose consumption in T. turnerae was clearly reduced under low salt concentrations. As a point of interest, we hereby report first hand that T. turnerae in fact exerts... |

| The presence of Aeromonas spp. in food has been demonstrated. They are often introduced from water, which is the natural habitat of many species and is thought to be the main source of contamination. The occurrence of Aeromonas spp. was investigated in 70 water samples of a bovine abattoir. Aeromonas spp. were present in 21.4% of water samples. A. hydrophila was isolated from 11.4% of supplying water samples and from 25.7% of the water drained from carcasses, whereas A. sobria was sole isolated from 5.7% of supplying water samples. Although greater number of positive samples were from water drained from carcasses, only A. hydrophila isolates were present. This suggests that the supplying water is the source of contamination. The antibiotic susceptibility... |
