The aim of this study was to assess the activity of essential oil extracted from the leaves of C. blanchetianus Baill, popularly known as "marmeleiro", in inhibiting the growth and survival of pathogenic microorganisms in food by determining their survival in vitro and by observing the behaviour of Listeria monocytogenes inoculated into a food model (meat cubes) that was stored at refrigeration temperature (7 ± 1 ºC) for 4 days. The results indicated a bactericidal effect against Aeromonas hydrophila and Listeria monocytogenes and bacteriostatic action against Salmonella Enteritidis. A bacteriostatic effect on meat contaminated with L. monocytogenes was found for all concentrations of essential oils tested. These results showed that essential oil from the...

Amorimia septentrionalis is a sodium monofluoroacetate (MFA) - containing plant that causes sudden death in ruminants. The aim of this study was to determine whether the resistance to A. septentrionalis poisoning in goats conferred by the intra-ruminal inoculation with the MFA-degrading bacteria Ancylobacter dichloromethanicus and Pigmentiphaga kullae can be transferred to susceptible goats by the transfaunation of rumen content. Two groups of 8 goats and 2 goats resistant to A. septentrionalis poisoning were used. Goats in Group 1 received four daily doses of 160ml of rumen content from resistant goats and subsequently ingested 8 daily doses of 5g kg-1 of A. septentrionalis. Goats from Group 2 (control) received only the plant. In Group 1, only 2 goats...
