The effect of Enterococcus faecium CCM7420 (EF) - enterocin-producing and probiotic strain of rabbit origin, Eleutherococcus senticosus extract (ES) and their combination (ES+EF) was determined on selected bacteria in faeces and caecum content, leukocytes phagocytosis, blood biochemistry and growth performance. Ninety-six weaned rabbits were divided into 3(More)
The gastrointestinal microbiota in rabbits play an important role in protection against potential pathogens via the development of the mucosal immune system. The gut health, including the microbial and immunological stability, is often influenced by exogenous factors, mainly around the weaning period. Therefore, alternative strategies are required to(More)
We investigated the effect of Enterococcus faecium on phagocytic activity, antioxidative status in vivo and the effect of E. faecium and 0.4% concentration of Thymus vulgaris essential oil (EO) on the duodenal tissue integrity in vitro in laying hens. The birds were fed the same standard diets and were divided into four groups. E. faecium was added to the(More)
The aims of this study were to isolate, identify and characterize the population of coagulase-negative staphylococci in different types of Slovak traditional sausages and to determine the metabolic properties of selected Staphylococcus xylosus and S. carnosus strains for the selection of potential starter cultures to use in the processing of sausages. The(More)
The antimicrobial spectrum of bacteriocin-producing enterococcal isolates from rabbits faeces, the biochemical characterization of bacteriocins, and their molecular mass and the presence of structural genes for bacteriocin production were investigated. Among enterococci selected from rabbit faeces, six strains of Enterococcus faecium (EF2019, EF1819,(More)
The ability of canine strain Enterococcus faecium EE3 to survive in healthy dogs and its effect on microbiological and biochemical parameters was determined. The strain was individually applied to 11 dogs per os at a dose of 10(9) CFU/mL (differed from 2 to 3 mL) for 1 week and persisted in feces for 3 months after cessation of its administration (reaching(More)
Enterococci are well-known producers of antimicrobial peptides--bacteriocins (enterocins) and the number of characterized enterocins has been significantly increased. Recently, enterocins are of great interest for their potential as biopreservatives in food or feed while research on enterocins as alternative antimicrobials in humans and animals is only at(More)
The experiment was conducted to determine the effects of the inoculation of the probiotic and enterocin A-producing strain Enterococcus faecium EK13 on selected parameters of metabolic profile, gut microflora, growth, and health in newborn piglets of Slovak White Improved. Piglets for study were divided into two groups: one group (EK13 group, n=8) received(More)
Probiotic utilization is becoming increasingly popular in veterinary medicine. However, only few probiotic products are available commercially for use in dogs in our market. Therefore, the aim of our study was to determine the properties of new potential probiotic Lactobacillus fermentum AD1 strain-own canine isolate and to investigate its effect on several(More)
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(More)
