This work considers the needs and methods of phage
therapy of two bacterial infections in poultry. The
review examines the use of bacteriophages, from the
moment of their discovery to the present day. We
discuss the relevance of such diseases as
compilobacteriosis and colibacteriosis transmitted
from birds to humans, we show how to use
bacteriophages and their efficacy in models of adult
birds and chickens, including information provided on
the pilot study of phage therapy at a poultry farm. The
reported study was partially supported by RFBR,
research projects No. 16-44-230855 and No. 13-04-
00991 and № 16-44-230855-р_а
Based on the information stored in the system of database management, biodiversity indices with special accent on measures of species richness are comparatively studied for Carabid beetles in various areas of the East Caucasus. Biodiversity indices are shown to be dependent on sampling or collecting techniques, sample size, geographic localization and its area
In root exudates of alfalfa, wheat and radish we have
found 12 amino acids. As well as 5 organic acids
were identified. In the variant with exudates of wheat
as the sole source of carbon and energy maximum
titer of microorganism Rhodococcus erythropolis
RCM Ac-2017D were observed
The review examines research unusual properties of
RNA. RNA has the ability to act as both genes and
enzymes (ribozymes). This property could offer a
way around the «chicken-and-egg» problem: genes
require enzymes; enzymes require genes.
Furthermore, RNA can be transcribed into DNA, in
reverse of the normal process of transcription. These
facts are reasons to consider that the RNA world
could be the original pathway to cells. The general
notion of an «RNA World» is that, in the early
development of life on the Earth, genetic continuity
was assured by the replication of RNA and
genetically encoded proteins were not involved as
catalysts. There is now strong evidence indicating
that an RNA World did indeed exist before DNAand
protein-based life. RNA has multiple functions.
Among these, "messenger RNA" carries genetic
information from DNA to protein formation. RNA is
often a single-stranded spiral, but also exists in
double-stranded form. In 1998, Craig Mello and
Andrew Fire discovered through their studies of the
roundworm C. elegans a phenomenon dubbed "RNA
interference". In this phenomenon, double-stranded
RNA blocks messenger RNA so that certain genetic
information is not converted during protein
formation. This "silences" these genes, i.e. renders
them inactive. The phenomenon plays an important
regulatory role within a genome. Recent years have
been perhaps the most fruitful period yet in terms of
research in the area of mRNA stability (Phenomena:
Gene Silencing; RNA interference; Identity of
mRNA decay in vivo and in vitro). The elaboration
of new methods in biothechnology have been
presented
The article is devoted to the construction of nomograms for determining geometrical dimensions of electroisolator the amount of residual pathogenic microflora on the surface of plant substrates

Influence of level of soil fertility, norm of fertilizers, systems of plant protection and a way of basic soil cultivation on accumulation and a ratio of chlorophylls in leaves of a winter wheat Nota during spring-and-summer vegetation is shown.
Pike inhabits almost all the rivers of the Yakutia
system. It is more widespread in the lakes of YanoIndigirka
and Kolyma lowlands. Objective: To provide
a modern assessment of fish in the main model
reservoirs, create an ecological prognosis and the
possibility of their use in modern conditions. Methods.
The material was collected in the conditions of
anthropogenic pollution. Full general biological
analysis was conducted for the fish. Cruise studies
were conducted covering the northern territories - r.
Anabar, Olenek, Lena, Yana, Indigirka, Kolyma and
Chrome, as well as Vilyuy Dam, from 1969 to 2016.
We used the standard ichthyologic methods of
selection and processing of the collected material.
Results. Because of climate warming, there were
reported pike approaches in the lower reaches of the
river Lena, Yana and Kolyma. Maximum dimensions
were noted earlier in the lower reaches of the river
Lena, where the maximum weight of pike was 18 kg.
The fecundity of 16-211 thousand eggs. It was
revealed, that the catch was better for young pike.
Conclusions. Stocks of pike are in satisfactory
condition, and its reserves are proposed to be
increased, at the expense of unused areas (lakes
Kolymo- Indigirka lowland) up to 220 m. It is
proposed as a fish-breeding facility in Yakutia
reservoirs
The article is concerned with the features of Lavandula’s
angustifolia vegetative propagation with methods of the
propagation by herbaceous cuttings and of the annual
woody cutting. The dependence of Lavandula’s varieties
Sineva and Vdala rooting of cutting and the cutting grafting
period and the age of the mother plantation was
established. In the fixed years, the rooting rate of cuttings is
58-67%. The maximum annual hardwood cuttings rooting
was observed from the fifth to the seventh year of the
cuttings’ workpiece (75-77%). The highest rooting rate of
green cuttings belonging to Vdala sort (80%) is observed in
the 3-4th years of use the mother plantation. The best result
for rooting rate by the annual woody cutting showed
Lavandula’s mother plantation, which belongs to Vdala
sort and was being cultivated from 3rd to 6th year. The
rooting of Lavandula’s angustifolia cuttings depends on
weather conditions; during drought years the rooting of
green cuttings is considerably reduced. During Lavandula’s
rooting cuttings it is necessary to take into account the
biological characteristics of each variety
Researches were spent in the conditions of the branch of FGBOU VPO «Orenburg State Agrarian University » of the Ilek zoo technical school and on the chair of noncontagious illnesses of animals at Orenburg State Agrarian University. The absolute and relative growth of the weight of a pancreas in ontogenesis was studied. All facts are subjected a statistical processing and during development the absolute and relative growth of the weight is established
Sunflower is one of the most important oilseed
crops, which are of great economic importance in
Russia and in the world. It is very adaptive crop
in terms of climatic conditions range, for that
reason it is cultivated on a vast territory of the
Russian Federation in various weather conditions.
Sunflower oil has high nutritional and taste
qualities, it is used numerously in food and is
applied in various fields of food industry. The
biologically active linoleic acid, phosphatides and
fat-soluble vitamins A, D, E and K, which are of
great nutritional value to humans, are contained in
the oil. According to its calorific capacity,
sunflower oil is on the first place among
vegetable oils. Due to biological characteristics of
sunflower, the Krasnodar region is the most
favorable region of the Russian Federation for
obtaining high and stable yields of this crop.
However, here the drought is observed during the
summer period and it affects adversely the
productivity and quality of sunflower seeds. The
increasing of resistance to unfavorable weather conditions is possible only based on detailed
study of physiological features of productivity
formation and seeds quality that is highly
important task in view of the current geopolitical
situation in Russia. One way of solving this issue
is the appliance of the growth regulators,
possessing anti-stress activity that improve the
quality of sowing seeds and increase the
productivity and plant resistance to stressful
environmental factors. These drugs include
growth regulator called Furolan, which was
created in KubGTU and is certified for use in
Russia. It is not toxic and is used in nano-dozes,
there is no its residual quantities in the products
and environment. Furolan has a positive effect on
physiological and biochemical processes,
improves the productivity of plants, their
resistance to unfavorable growing conditions by
increasing the resistance to dehydration as well as
to the risk of fungal diseases
