In this article data concerning coherent fluctuation nephelometry (CFN) use in clinical microbiology is presented. CFN-analyzer allows to solve two important problems – fast urine screening for bacteriuria within 2-4 hours and antibiotic susceptibility testing within 3-6 hours. Altogether more than 650 urine samples were tested, and the effectivity of CFN-analyzer for preliminary selection of samples for further analysis was shown. Method allows to detect negative samples, reducing the number of urine analyses by 70-80%. Simultaneous analysis of growth curves and concentration of microorganisms shows high sensitivity and specificity (95.2% и 96.9%). Also more than 250 antibiotic susceptibility tests were performed using CFN-analyzer to show its effectiveness for determination of resistant properties of both pure cultures and urine microflora without isolation of bacteria. The agreement with traditional methods was from 84% to 88%. The use of CFN-analyzer with express methods of identification of microorganisms (chromogenic nutrient broths or mass-spectrometry) allows to make full urine analysis within 1-2 days. In the future CFN-analyzer gives an opportunity to screen different human biological liquids, and finds an application for other microbiological tasks, including standardization and speeding-up in sanitary bacteriology.

The article deals with the problems of calculating the cost of agricultural products in crop and livestock production, associated with the methods of production accounting and management accounting systems for production facilities used in practice by agricultural organizations. Variants of definition (selection) of cost accounting objects, objects of calculation of the first order and objects of calculation of the second order are proposed. Conceptual models for the distribution of costs between the objects of the first-order calculation, the objects of the second-order calculation and the calculation of the cost of the received types of agricultural products have been developed. Using the example of the production of the main herd of dairy cattle, it is shown that the use of old methods of calculating the cost of agricultural products is not consistent, and it is recommended to use more justified methods of calculating the cost of crop and livestock products, recommended in the new editions of the relevant guidelines of the Ministry of Agriculture of the Russian Federation.

In veterinary practice, a large list of antibiotics is used as therapeutic and/or prophylactic agents.Some of them are used as stimulators of the growth and productivity of animals.However, non-observance of the rules for the use of antibiotics and / or timing of slaughter or obtaining milk leads to the intake of a residual amount of antibiotics into the human body with food and can cause various pathologies. The article provides an overview of research papers published in peer-reviewed journals from 2015 to the present on the development and improvement of methods for testing milk and meat for antibiotics. Based on the literature review and the results of his own study, the author of the article notes the advantages of enzyme-linked immunosorbent assay (ELISA) options over instrumental analytical methods, such as liquid chromatography with tandem mass spectrometry and high-performance liquid chromatography. However, due to the complexity of the analysis procedure, ELISA kits are not used in food safety laboratories in the Republic of Kazakhstan and other CIS countries. The article describes the state and prospects for the development of simple rapid tests to determine the maximum residue limit (MRL) for antibiotics in livestock products, based on the use of Lateral Flow Assay (LFA). Such tests, not inferior in their sensitivity to ELISA and surpassing it in cost, could be used not only in laboratory conditions, but also directly by food consumers, which will contribute to reliable protection of public health and the development of animal husbandry.
