Résumé:
Poisoning of domestic animals by plants containing sodium monofluoroacetate,
cause great economic losses, since there is no antidote capable of reversing intoxication
and prophylactic measures available are not totally effective. The ruminal detoxification
is a mechanism that has been used as an alternative control in poisoning by plants. Can
be realized by bacteria able to degrade toxic compounds, such as sodium
monofluoroacetate, usually this degradation is facilitated by the production of enzymes
called dehalogenases. The objective of this study was to evaluate, in goats, the
resistance present in MFA Amorimia septentrionalis induced by inoculation of ruminal
bacteria Pigmentiphaga kullae and Ancylobacter dichloromethanicus isolated from the
rumen of goats. The goats were divided into two groups, each with 6 animals. In group
1, 60 ml of a solution containing the bacteria was inoculated into each animal daily for
10 days. In group 2, the goats received no bacteria. On the tenth day of inoculation was
offered to all goats plant at a dose of 5 g/kg body weight daily in each animal being
stopped watching after the first clinical signs of intoxication. Goats from group 1
showed clinical signs 5.83 ± 2.56 days after administration of the plant which differed
significantly (p = 0.037) in goats of group 2, which showed clinical signs to 2.67 ± 0.52
days. The amount ingested by plant inoculated goats (28.83 ± 12.97 mg / kg) and noninoculated
(12.03 ± 3.65 g / kg) to cause clinical signs was also statistically different
between groups (p = 0.025). So it is concluded that administration of rumen bacteria
Pigmentiphaga kullae and Ancylobacter dichloromethanicus induces resistance to
poisoning plants containing sodium monofluoroacetate, enhancing its use as a means of
controlling the poisoning.
