The investigations were conducted on 60 Holstein-Friesian dairy cows (at age 3 year and weight 590 kg) kept in tie-stall barn. The animals were divided into 3 groups of 20 heads each. The control group (K) was fed diets without probiotics, group (EM) – was fed diet with the addition of EM probiotic (dose of 150 ml × t–1 TMR) and group (T) – was fed diet with the addition of ToyoCerin probiotic (dose of 0.2 kg × t–1 TMR). Strains of Escherichia coli were isolated from faeces with the aim to determine their numbers, capability for hemolysis and assessment of their drug-resistance. The isolates were identified as E. coli on the basis of their biochemical properties API 20E (BioMérieux) and the PCR method. When analysing the capability of Escherichia coli for hemolysis, the highest number of haemolytic strains was determined in the faeces of animals fed diets with the addition of the EM probiotic. The examined isolates were characterised by different degrees of resistance to the antibiotics used in experiments. The smallest (P<0.05) number of resistant isolates was determined in group T.

The investigations were conducted on 60 Holstein-Friesian dairy cows (at age 3 year and weight 590 kg) kept in tie-stall barn. The animals were divided into 3 groups of 20 heads each. The control group (K) was fed diets without probiotics, group (EM) -- was fed diet with the addition of EM probiotic (dose of 150 ml ⋅ t-1 TMR) and group (T) -- was fed diet with the addition of ToyoCerin probiotic (dose of 0.2 kg ⋅ t-1 TMR). The volume of 2--10 cm$^3$ saliva was collected from each animal in which the following parameters were determined: number of lactic acid rods from the Lactobacillus genus, number of rods capable of producing hydrogen peroxide. For purpose of precise diagnostics, lactic acid rods were identified on the basis of biochemical traits employing API 50 CHL (BioMérieux), while those manufacturing H2O2 were additionally tested using PCR method. The occurrence of Lactobacillus spp. rods was confirmed in all the examined individuals and in each and every experimental combination. Lactobacillus spp. rods capable of produce hydrogen peroxide were isolated in 17 cows in group K, in 3 individuals in group EM and in 13 animals in group T. EM probiotic strongly significantly restrict the development of Lactobacillus spp. strains are capable to produce hydrogen peroxide.

The investigations involved determining the influence of the way of ensiling of alfalfa on the content of some selected biogenic amines in silages, changes in the content of dry matter, crude protein, lactic and acetic acids as well as of ammonia. The performed microbiological analysis entailed determining total counts and the frequency of occurrence of: Lactobacillus spp. (L. plantarum, L. buchneri, L. brevis), as well as Enterobacteriaceae bacteria mainly responsible for the level of amine concentrations. Experimental silages were prepared from fresh and wilted Lucerne, also using a chemical additive. The highest biogenic amine totals and the highest counts of Lactobacillus spp. and Enterobacteriaceae bacteria were recorded in silages prepared from wilted alfalfa. The applied chemical additive reduced the level of amines in silages and Enterobacteriaceae counts.

 Numerous studies have shown that consumption of soybean products decrease the risk of cancers in humans. Experiments at the molecular level have demonstrated that in most cases proteins and peptides are responsible for the anticancer properties of soybeen. Special attention should be paid to lunasin - a peptide described for the first time 16 years ago. Due to its structure it causes i.a., inhibition of cancer cell proliferation. A novel procedure for the isolation and purification of low-molecular-mass 2S soybean albumin protein is described in the present paper. A fraction of four peptides one of them corresponding to molecular mass and isoelectric point characteristic for lunasin. The obtained peptides decreased on the rate of HeLa cell proliferation.

The investigation was performed on 75 of Golden Retriever puppies. Faecal samples were collected on the 42 day of the puppies life (control). Probiotic preparation was administered on 43 day of the puppies life and 10 days after the application of the probiotic, faecal samples were collected again (on 53 day of puppies life). All isolates of Campylobacter coli isolated prior to the administration of the probiotic were found to contain the cadF gene responsible for adhesion, as well as, the flaA gene influencing motility of the examined bacteria. Significant differences (P < 0.05) were recorded only in the case of enrofloxacin.

This study was conducted to determine the prevalence of Campylobacter spp. isolated from dogs’ faecal samples. From June 2012 to June 2013, a total of 210 faecal samples from pet dogs living in different kennels (n=210) were collected by the owners in Greater Poland Voivodeship, Poznań District, Poland. The study revealed that 105 out of 210 faecal samples (50%) contained Campylobacter. The highest prevalence of Campylobacter spp. occurred in spring (81%), followed by winter (64%). The cadF gene was found in 100% of the isolates tested. The occurrence of the other genes was variable. The isolates from young dogs were characterised by higher occurrence of virulence genes.
