“…At recent time, an increase in the number of studies testing enterocins in vivo was noted; there are more studies involving poultry, pigs, cows, food (Foulquié Moreno et al 2006, Strompfová et al 2006, Svetoch and Stern 2010. In rabbits husbandry, post-weaned period is problematic.…”

Enterocin (Ent) 4231, produced by non-rabbit origin strain Enterococcus faecium CCM 4231 was used in combination with sage plant extract in rabbits with the aim to check their antimicrobial activity against microbiota, their effect on immunological, biochemical blood parameters, values of volatile fatty acids in caecum, Eimeria sp. oocysts occurrence and selected parameters of rabbits meat. The animals were divided into three experimental groups (EG1-Ent 4231; EG2-sage; EG3-Ent 4231 with sage) and control group (CG); 24 rabbits in each. Natural substances (NS) were administered for 21 days. The experiment lasted for 42 days. The reduction of microbiota in faeces was observed in EG3 at day 21 by a decrease in the numer of coagulase-positive staphylococci (P<0.01) in comparison with that determined in CG. The bacterial counts in the caecum were lower than those found in faeces. A decrease in the numer of Pseudomonas-like sp. in caeca of the experimental groups was observed at days 21 and 42 (difference in range 0.40-1.87 log cycles) comparing with that determined in CG. At day 21, a significant increase in phagocytic activity (PA, P<0.001) was found in blood of rabbits from EG2 comparing with that observed in CG. At day 42, a significant increase in PA (P<0.001) was determined in all experimental groups in comparison with CG. At day 21, in caecal content of EG3 significantly higher values of lactic acid were observed (P<0.05) in comparison with those found in CG. The reduction of Eimeria sp. oocysts was demonstrated after application of each of NS. Addition of NS did not influence biochemical parameters, meat quality of the animals and does not influence negatively the health status of rabbits.

“…Beneficial bacteria isolated from different sources are widely used in veterinary medicine and these act mainly by producing inhibitory substances (Strompfová et al, 2006;Diez-Gonzalez, 2007;Veir et al, 2007). For example, Lactobacillus amylovorus, producing a highly acidic inhibitory substance, shows high antibacterial ability against diarrheal pathogens in pigs (Klose et al, 2010).…”

ABSTRACT. The purpose of this study was to assess the suitability of lactic acid bacteria (LABs) isolated from Muscovy duck as a potential probiotic. Isolates were identified by targeted polymerase chain reaction and assessed in vitro for probiotic characteristics such as autoaggregation; surface-charge; hydrophobicity; tolerance to acidic pH, bile salts and protease; and expression of genes involved in Caco-2 cell adhesion. The LAB isolates exhibited strong resistance to high bile concentration and acidic pH, produced lactic acid, and bacteriostatic (P < 0.05) were identified as bacilli compared with LAB isolates of cocci. Additionally, the LAB isolates showed high sensitivity to penicillin and tetracycline antibiotics, while they were resistant to ofloxacin, Macrodantin, and cotrimoxazole. The level of F-actin mRNA increased in the groups treated with CM3, Salmonella enterica, and CM3 + S. enterica (P < 0.0001, P < 0.05 and P < 0.05 ). The level of cell adhesion molecule (CAM) and E-cadherin (E-cad) mRNA expression was significantly lower in the treatment group (P < 0.05 for both) than in the control. The F-actin, CAM, and E-cad mRNA levels were significantly lower in the S. enterica and CM3 + S. enterica groups (P < 0.01) than in the CM3 group. Among these, RNA levels were higher in the CM3 + S. enterica than S. enterica group. These results indicate that the natural duck gut microflora is an excellent source for probiotic bacteria and can facilitate the establishment of criteria to select probiotic strains for the prevention of diarrhea.

“…Hypercholesterolemia is one of the most significant risk factor for the cardio-vascular diseases. It has been determined that various probiotic species decrease the serum cholesterol levels in human (Larkin et al, 2009), experimental animals (Park et al, 2007) or farm animals (Özcan et al, 2003;Strompfova et al, 2006). However hypocholesterolemic effect of probiotics depends on the species of the bacteria.…”
