WIEST, J.M.; CARVALHO, H.H.C.; AVANCINI, C.A.M.  and  GONCALVES, A.R.. In vitro inhibition and inactivation activity of Salmonella spp. by plant extracts with spicy or medicinal ethnographic indicative. Arq. Bras. Med. Vet. Zootec. [online]. 2009, vol.61, n.1, pp.119-127. ISSN 1678-4162.

The in vitro intensity of bacterial inhibition activity of diverse extracts (aquous, alcoholic, or hydroalcoholic) from 86 plants with medicinal and spicy ethnographic indicative, from Porto Alegre City, Rio Grande do Sul State, Brazil, were determinated in Salmonella spp. (S. enteritidis ATCC n.13076, S. cholera-suis ATCC n. 10708, or S. gallinarum CPVDF-SAA/RS/BR) in challenge dose <107CFU.mL-1. Extracts of fifty plants presented some anti-Salmonella selective activity, while the other 36 extracts presented no activity. It is discussed the validity of ethnographic search instruments in the prospection of anti-bacterial protection factors in plants, as well the influence of inhibition/inactivation results in the predictivity of bacteriological diagnostic.

Keywords : medicinal plant; antibacterial activity; inhibition; inactivation; Salmonella spp.
