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 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 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)
Faecal samples from 23 rabbits of various age from 5 different rabbit flocks were examined for the presence of enterococci. Fifty-eight strains of Enterococcus sp. enumerated in the range from 10 to 10 CFU/mL were genotyped using PCR followed by agarose electrophoresis. Fifty percent of the isolates identified as Ent. faecium were tested for sensitivity to(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)
Faecal samples of 122 horses (from farms in Slovakia) were examined to select enterococci to study their probiotic potential for their further use as additives. Each gram of faeces contained 1.0-5.0 cfu (log 10) of enterococci. Of the 43 isolates, 25 (58.1%) were identified as Enterococcus faecium, 3 strains were (6.9%) Enterococcus mundtii and one strain(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 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)
The ability of canine strainEnterococcus faecium EE3 to survive in healthy dogs and its effect on microbiological and biochemical parameters was determined. The strain was individually applied to 11 dogsper os at a dose of 109 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)
