“…Simultaneously, an increase in the number of attached streptococci and bifidobacteria, and a reduction in beneficial Lactobacillus cells attached to the intestine occurred (Table 3). Lactobacilli possess a great ability to adhere to the intestinal epithelium and to prevent potential infection by competitive exclusion (Tierney et al, 2004;Lin et al, 2007). Similarly, Bifidobacterium strains are commonly considered as key commensals that promote health of the gut.…”

Maintaining gut health and well balanced intestinal microflora is important for the profitable production of high quality poultry. We investigated the impact of mannanoligosaccharides (MOS) in comparison with flavomycin on turkeys performance and intestinal colonization by harmful and beneficial microflora. Two hundred forty turkeys (four replicates of 12 birds per treatment) were fed on diet supplemented with flavomycin (8 mg/kg feed) or with low (1g/kg feed during the entire study), medium (4 and 2 g/kg feed in the first and second 8-week periods, respectively) and high (10 and 4 g/kg feed in the first and second 8-week periods, respectively) level of MOS. Basal diet without supplements was applied as control. After 16 weeks of feeding, the animals were sacrificed and microbial populations (Bifidobacterium, Lactobacillus, streptococci, Escherichia coli and other enterobacteria) attached to the colonic epithelium were assessed. Moreover, colonic epithelia were washed to remove the bound microorganisms and examined for their susceptibility for colonization by exogenous probiotic and pathogenic strains in vitro. In all experimental groups the reduction of the bacteria attached to the epithelium was found, except for increase of streptococci in flavomycinreceiving group and bifidobacteria in flavomycin and MOS-receiving groups. Higher doses of MOS had stimulating effect on body weight gain. In vitro studies revealed a great potential of MOS to reduce attachment of enterobacteria and in higher doses to enhance adhesion of Bifidobacterium and selected Lactobacillus strains (P<0.05).

ABSTRACT:A bacteriocin-like substance (BLS) producing Enterococcus faecium CE5-1 was isolated from the gastrointestinal tract (GIT) of Thai indigenous chickens. Investigations of its probiotic potential were carried out. The competition between the BLS probiotic strain and antibiotic-resistant enterococci was also studied. Ent. faecium CE5-1 exhibited a good tolerance to pH 3.0 after 2 h and in 7% fresh chicken bile after 6 h, but the viability of Ent. faecium CE5-1 decreased by about 2-3 log CFU/ml after 2 h incubation in pH 2.5. It was susceptible to the antibiotics tested (tetracycline, erythromycin, penicillin G, and vancomycin). The maximum BLS production from Ent. faecium CE5-1 was observed at 15 h of cultivation. It showed activity against Listeria monocytogenes DMST17303, Pediococcus pentosaceus 3CE27, Lactobacillus sakei subsp. sakei JCM1157, and antibiotic-resistant enterococci. The detection by polymerase chain reaction (PCR) in the enterocin structural gene determined the presence of enterocin A gene in Ent. faecium CE5-1 only. Ent. faecium CE5-1 showed the highest inhibitory activity against two antibiotic-resistant Ent. faecalis VanB (from 6.68 to 4.29 log CFU/ml) and Ent. gallinarum VanC (from 6.76 to 4.31 log CFU/ml) after 12 h of co-cultivation. The results show the future possible use of Ent. faecium CE5-1 as a probiotic strain for livestock to control antibiotic-resistant enterococci.

“…L. acidophilus has been reported for the production of acidocin and lactacin B and F (Parada et al, 2007). L. fermentum, isolated from the gastrointestinal digestive tract and mucosa in the swine and poultry have been described as potential probiotic organisms and inhibitors of enteric pathogens of these animals, especially against E. coli, Salmonella spp., Shigella sonnei, and with less efficiency, enterotoxigenic Staphylococcus aureus (Lin et al, 2007). Studies about kinetic of antimicrobial production in co-cultivation system showed that the maximal production occurred after about 36 to 48 h fermentation (Figure 2).…”

“…In this context, the lactic acid bacteria appear as an interesting alternative for this application due to their flexibility for use as a probiotic organism, by the use of cells to adhesion, colonization and organic acids production in the intestinal tract, and also for the synthesis of low molecular weight peptides with bactericidal or bacteriostatic effects -the bacteriocins (Parada et al, 2007;Lin et al, 2007). The aim of this study was to investigate the potential of isolates belonging to the strains bank of the Bioprocess Engineering and Biotechnology Department at Universidade Federal do Paraná (UFPR, Brazil) to produce antimicrobial compounds capable of inhibiting the Gramnegative pathogen growth isolated from the animal faeces, and finally, perform a study on their antimicrobial substance production.…”
