“…In general, the reduction in sporulation of the oocysts of E. tenella observed in this study in combination with previous reported reduction in invasion of E. tenella under in vitro conditions [17] may support the hypothesis that Lactobacillus species produce antimicrobial compounds harmful to coccidian oocysts.…”

“…Consequently, the significant reduction in sporulation of the fecal oocyst shed by birds fed CFS-supplemented diet will lead to less contamination with infective coccidian oocysts. Similarly, Tierney et al [17] studied the effect of extracellular components of indigenous chicken Lactobacillus species on invasion of E. tenella under in vitro conditions and found that extracellular metabolic factors secreted by Lactobacillus species into the surrounding media were shown to inhibit parasite invasion and these factors appeared to be heat stable. The researchers concluded that the natural microflora of poultry can provide a source of E. tenella-inhibiting Lactobacillus species in vitro, and thus may contribute to the control of Eimeria infection.…”

“…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).

“…For chickens, these functions involve the resistance to enteric infections, such as the protection against Salmonella infection [7,8] or Eimeria parasitizing [4,[9][10][11]. Studies also have shown that for disease prevention and immune enhancement, multistrain probiotics are more effective than monostrain probiotics due to the additive and synergistic effects.…”

A multistrain formula (MF) consisted of four selected lactic acid bacteria (LAB) strains was evaluated for its function to ameliorate the growth rate and inflammation of broiler chickens caused by Eimeria tenella parasitizing. Thirty one day broiler chickens were divided into 3 groups with 10 chickens in 2 cages per group. These groups were control, infected and MF groups. In control group, chickens were fed with 0.2 ml PBS and not challenged with E. tenella. In MF group, chickens were gavage fed with 0.2 ml of MF (109 CFU/ml) from day 1 to day 23. On day 14, each chicken in both the infected and MF groups was challenged with 5,000 sporulated E. tenella oocysts. Seven days post infection, it was found that the average body weight gain (ABWG) for chickens in the infected and MF groups were 281.51 ± 61.00 and 295.52 ± 62.16 g per chicken, respectively. Chickens in each group were then sacrificed and their cecal tonsils collected. It was observed that feeding MF could reduce the cecal lesion scores (LS) of the Eimeria infected chickens significantly. In addition, for chickens in the MF group, the levels of cecal gene expression of proinflammatory cytokines, such as interleukin (IL)-1β, IL-6, and interferon (IFN)-γ, were found significantly lower, while anti-inflammation cytokine, ie, IL-10, was significantly higher than those of the chickens in the infected group. This study thus suggests that the MF, which previously has been shown to have antagonistic effect against Salmonella infection and the induced inflammation either in live or in heat killed form, may also be useful for the amelioration of the growth rate and the inflammation of broiler chickens caused by E. tenella infection.
