“…These results were not different from those reported in previous studies (Gouet et al. 1976; Forsythe and Parker 1985; Canganella et al. 1992), suggesting that staphylococci may be constituents of the autochthonous intestinal microbiota of rabbits.…”

“…These studies have revealed that the intestinal microbiota of rabbits consists predominantly of strictly anaerobic, Gram-negative bacteria belonging to the genus Bacteroides, while anaerobic sporulated Gram-positive bacteria are present in significantly lower numbers (Forsythe and Parker 1985;Zomborszky-Kovács et al 2000). Facultative anaerobic bacteria isolated from the intestinal tract of rabbits belong to the Gram-positive genera Bacillus, Enterococcus and Staphylococcus, and Gram-negative Enterobacter and Escherichia (Forsythe and Parker 1985;Canganella et al 1992). In contrast with other mammals, lactobacilli are very rarely found (Yu and Tsen 1993).…”

“…These diseases have been usually treated by administration of antimicrobial substances. Nevertheless, there is an increasing concern on the preventive use of antibiotics in animal feeding and probiotics may constitute a safe alternative, as they can stimulate the immune system, prevent invasion by pathogenic micro-organisms by competitive exclusion and production of antimicrobial substances (Salminen et al 1996;Dunne et al 1999) and maintain the microbial balance (Gouet et al 1976;Canganella et al 1992). Bacteria most commonly used as probiotics include the lactic acid bacteria and bifidobacteria.…”

Characterization of faecal enterococci from rabbits for the selection of probiotic strains

Aims: To characterize the facultative anaerobic intestinal microbiota of healthy rabbits, especially enterococci, for the selection of potential probiotic strains. Methods and Results: Phenotypic and molecular methods were used to identify enterococcal isolates. Results obtained indicated that enterococcal microbiota widely varied among individuals both in size and in composition. Antibacterial and haemolytic activities, and resistance to acid and bile salts were determined. A small group of strains produced bacteriocins active against listeriae and indigenous clostridia and therefore they were selected as potential probiotics. One such strain, 8G, was assayed for colonization capacity. Results obtained suggested that the fate of the introduced strain depended on the composition of the enterococcal indigenous microbiota. Conclusions: Enterococcus faecalis and Ent. faecium are the predominant enterococcal species in the gut of rabbits. Other species of lactic acid bacteria were not recovered. Significance and Impact of the Study: The enterococcal intestinal microbiota of healthy rabbits has been characterized in detail. Monitoring the fate of an introduced probiotic in vivo is required in order to evaluate potential probiotic strains.

“…In rabbits, there have been no reports on S. lentus in saliva, nasal wash or feces. However, S. lentus was found to be a minor indigenous bacteria in the colon in one rabbit out of the three but was not found in the small intestine or the rectum (4). We did not find S. lentus in the small intestine, but found a small number of cells in the feces.…”

In rabbits, Staphylococcus lentus is one of the major bacteria in saliva and a minor bacteria in jejunum fluids and nasal wash. The presence and induction of naturally occurring antibodies reacting to rabbit indigenous bacteria were studied. In non-immune rabbits, the proportion of anti-S. lentus IgA antibodies to total IgA in the saliva was several times higher than that in the intestinal fluids and the nasal wash. The salivary antibodies were found to have increased 1 week after a single tonsillar application of isolated S. lentus cells but not after a single nasal application or a single intragastric instillation. In addition, the anti-S. lentus antibodies in the saliva highly increased with weekly tonsillar applications of isolated S. lentus but increased only one-fifth with weekly nasal applications of the same cells. These results strongly suggest that the palatine tonsils, which we believe had already been sensitized by S. lentus in the physiological condition, induced naturally occurring antibodies in rabbit saliva.
