摘要

The prebiotic potentials of crude extracts of?Vernonia amygdalina?and?Ocimum gratissimum?in rabbit (Oryctolagus cuniculus)?were studied. The aqueous leaf extracts of both plants, taken orally, were evaluated for their effects on the composition and relative abundance of the rabbit gastrointestinal microflora as well as their protective roles against gastrointestinal infection by selected test organisms. The crude extracts were administered to eight-week old rabbits with average weight of 0.85??±??0.14 kg, at a dosage? of 0.1 g/day. Species of?Corynebacterium, Enterococcus, Bacteroides, Lactobacillus?and?Actinomyces?were identified as resident bacteria in the rabbit gastrointestinal tract (GIT). Consumption of?Vernonia amygdalina?extract selectively and significantly (p < 0.05) increased the numbers ofEnterococcus?and?Actinomyces?species recovered from the animals faecal specimens, while?O. gratissimum?increased only the?Actinomyces?species. In contrast, the numbers of?Bacteriodes?species were significantly decreased by both extracts. Consumption of?V.?amygdalina?extract also reduced colonization and damage of the animals GIT by?Escherichia coli?and?Staphylococcus aureus?as evidenced by restricted shedding of the organisms in faeces and histopathological examination of colon tissues. The results from this study showed that the?V.amygdalina?leaf extract has prebiotic effects in the rabbit GIT including protection of the animals against some GIT pathogens.
