“…However, we must bear in mind that the inoculation of enterococci was not interrupted. As previously reported, the use of an enterococcal probiotic showed beneficial effects on both intestinal health and growth rates (Linaje et al, 2004;Simonová et al, 2009;Benato et al, 2014).…”

“…Genera such as Lactobacillus, Streptococcus, Enterococcus and Escherichia are considered to be in low density or even rare in the digestive microbiota of rabbits (Combes et al, 2011;Eshar and Weese, 2014). However, feed supplementation with probiotics composed of such unusual bacterial inhabitants was already reported as being successful in increasing the faecal levels of certain beneficial intestinal bacteria in healthy adult rabbits (Benato et al, 2014).…”

“…Enterococcus spp. is a well-recognised genus of the caecal flora of healthy adult rabbits and commonly considered in probiotic formulas (Straw, 1988;Benato et al, 2014). In contrast, E. coli is an unusual species of the rabbit gut, but it is hypothesised that providing the animals with E. coli strains recovered from healthy individuals' intestinal microbiota may protect them from dysbacteriosis.…”

Effect of competitive exclusion in rabbits using an autochthonous probiotic

et al. 2017

Animal nutrition has been severely challenged by the ban on antimicrobials as growth promoters. This has fostered the study of alternative methods to avoid colonisation by pathogenic bacteria as well as to improve the growth of animals and feed conversion efficiency. These new options should not alter the normal intestinal microbiota, or affect it as little as possible. The use of probiotics, which are live microorganisms that beneficially affect the host by improving its intestinal microbial balance, can be seen as a promising way to achieve that goal. In this study, New Zealand White rabbits were fed diets containing an autochthonous probiotic of Enterococcus spp., with the strains EaI, EfaI and EfaD, and Escherichia coli, with the strains ECI 1, ECI 2 and ECD, during a 25-d trial, to evaluate the impact of the probiotic on the faecal microbiota, including population dynamics and antimicrobial resistance profiles. A control group of rabbits, which was fed a diet containing a commonly used mixture of antimicrobials (colistin, oxytetracycline, and valnemulin), was also studied. To assess the colonisation ability of the mentioned probiotic, the faecal microbiota of the rabbits was characterised up to 10 d after the administration had ended. Isolates of enterococci and E. coli were studied for phylogenetic relationships using enterobacterial repetitive intergenic consensus (ERIC-PCR) and pulse-field gel electrophoresis (PFGE), respectively. Although partially affected by an unexpected clinical impairment suffered by the rabbits in the experimental group, our results showed the following. The difference between the growth rate of the animals treated with antimicrobials and those fed the probiotic was not statistically significant (P> 0.05). The competitive exclusion product was present in the faecal samples in a large proportion, but stopped being recovered by culture as soon as the administration ended and the housing conditions were changed. Multidrug-resistant strains of enterococci and E. coli were more commonly recovered from faecal samples of animals fed diets containing antimicrobials, than from rabbits fed diets with our probiotic formula. The use of E. coli probiotics to prevent infection by enteropathogenic strains must be carefully considered due to the possible occurrence of gastrointestinal signs. On the other hand, enterococci strains may be more effective, but lack the long-term colonisation ability.

“…Available probiotics include the Lactic acid bacteria, Enterococci, Bifidobacteria, Yeasts and so on. They are extensively used in the medical and veterinary fields to treat and reduce the symptoms of many gastrointestinal diseases and as a preventive approach to maintain a healthy gut flora [8][9][10]. Previous studies on intestine biodiversity of rabbits performed using classical culture-based techniques and recently, by molecular techniques.…”

Rabbits are both monogastric and herbivore animals, with special digestive and physiological characteristics. The establishment of healthy, stable and diverse digestive tract microflora is of great significance for rabbits to resist intestinal diseases.Probiotics have been defined as living bacteriawhich modulate the gut microflora and improvethe health of the host beyond their inherent basicnutrition.The purpose of this paper is to summarize the role of intestinal microbes and the effects of probiotics on their intestinal microbes.

“…There are an estimated 400 different species of bacteria inhabiting the rabbit caecum, of which 25 are considered the most abundant [29]. In adult rabbits, strict anaerobes are the most prevalent bacteria and of these, Bacteroides species are considered dominant [30].…”

Effects of probiotic Enterococcus faecium and Saccharomyces cerevisiae on the faecal microflora of pet rabbits

Abstract: The inclusion of dietary probiotic supplementation using E. faecium NCIMB 30183 can increase faecal levels of certain bacterial flora of healthy adult rabbits. Further work is required to investigate the effects of probiotics in animals affected with gastrointestinal disease.
