“…Colibacillosis hence leads to considerable economic losses in poultry farming [4,8]. In the Russian Federation 83% of poultry farming is accounted to conventional agricultural farms/organizations and produces almost 5 million tons of poultry in live weight per year [9].…”

Escherichia coli strains isolated from case of colibacillosis in Russian poultry farms in the region of Perm Krai were analyzed for their sensitivity to main antibiotics and bacteriocins. Sensitivity profiles for 9 antibiotics and 20 bacteriocins were determined with the disc diffusion method and the overlay test, respectively. Further, with the PCR the presence of several bla and integron 1 genes was revealed and the phylogenetic group for each strain determined. Among the 28 studied E. coli strains 85.7% were resistant to at least three antibiotics, 53.6% to five or more drugs, and 10.7% to eight antibiotics. PCR revealed that the blaTEM gene was harbored by 71.4% of strains and the blaCTX-M gene by 53.6% of strains. The class 1 integrons were found in 28.6% of strains. All of the studied strains were insensitive to ten or more bacteriocins. More than 90% of the studied strains were insensitive to pore-forming colicins of group A and B colicins, while 60.7% were insensitive to colicins with DNase and RNase activity. All of the analyzed strains were insensitive to at least two of the tested microcins. Neither the antibiotic resistance profile nor the bacteriocin resistance profile correlated with phylogenetic group of the strains. Thus, the studied strains were shown to possess high levels of multiple resistance to antibiotics and insensitivity to bacteriocins.

The paper presents data on the study of the influence of the metabolic probiotic (metaprobiotic) Biosib METAPRO, developed based on a complex of cultures Bifidobacterium longum and Lactobacillus plantarum at LLC “Sibbiopharm”, on the indicators of protein metabolism in broiler chickens. The study was conducted on Ross 308 cross chickens from 6 days to 35 days of age, using four groups: control and three experimental groups, to which Biosib METAPRO was additionally administered in different doses. The quantitative assessment of protein metabolism indicators in the blood serum of birds was performed photometrically using Vector-Best reagent kits. It was established that the levels of total protein, albumin, globulin, albumin/globulin ratio, alanine aminotransferase (ALT), aspartate aminotransferase (AST), de Ritis coefficient, and creatinine in broiler chickens were within the generally accepted physiological norms for birds of this age or showed insignificant deviations. Statistical analysis revealed a significant influence of the metaprobiotic on total protein, A/G ratio, ALT, AST, de Ritis coefficient, and creatinine. The most pronounced changes were observed in chickens receiving Biosib METAPRO at a dose of 0.05%. The greatest number of differences was found between the control and the 1st experimental (Biosib METAPRO at a dose of 0.05%) groups. When administering the preparation at this dosage to broiler chickens, the level of total protein increases by 9.97 g/l, there is a change in A/G ratio, an increase in ALT activity by 1.32 mmol/l⋅h, a decrease in AST by 3.76 mmol/l⋅h, normalization of the de Ritis coefficient, and an increase in the level of creatinine by 13.2 µmol/l (p0.05). The results of the study demonstrate the positive influence of the metabolic probiotic Biosib METAPRO on protein metabolism in broiler chickens, which may contribute to increasing the efficiency and sustainability of poultry meat production.
