[The study of the raw milk contamination by bacteria of the genus Campylobacter using traditional microbiological methods and quantitative PCR assay].

Gastroenterocolitis caused by Campylobacter bacteria are the most common acute infectious zoonotic foodborne diseases. One of the important factors for the transmission of infection is contaminated dairy products, so the assessment of contamination of raw milk with Campylobacter is necessary to develop effective measures to suppress the growth of the pathogen and ensure the safety of products. of the study was to assess the microbial characteristics of raw milk samples and the nature of their contamination with thermophilic bacteria of the Campylobacter genus.

Growth and Persistence of Campylobacter jejuni in Foodstuffs.

Campylobacter genus bacteria causing campylobacteriasis are difficult to culture. This fact necessitates creation of special approaches to studies of the behavior of these pathogens during the manufacture and storage of foodstuffs. The regularities of Campylobacter jejuni transition into an uncultivable state are studied under conditions simulating the process of immersion cooling of fresh poultry products.

[Optimization of microbiological methods for food control based on the differential-diagnostic media for the isolation and cultivation of bacteria of the genus ].

А screening study on the detection of campylobacteria in raw food products, semi-finished products and objects in the external environment in the poultry processing industry was conducted. The highest level of detection of campylobacteria is set for raw poultry products, including carcasses of broilers, turkeys and quail. A general accordance of getting Campylobacter in raw materials and food products with inadequate sanitary treatment of separate areas of production has been established: in most cases Campylobacter spp.

[Subacute oral toxicity of multi-walled carbon nanotubes].

Multiwall carbon nanotubes (MWCNTs) are regarded as environmental pollutants with increased risk. Recently MWCNTs have attracted attention as a promising component of packaging materials for food products, as carriers for agricultural plant growth stimulants, agrochemicals components and advanced pesticides, which creates the possibility of their exposure through the gastrointestinal tract. Objective of the research is assessment of sub-acute oral toxicity to rats of MWСNTs in an experiment lasting 100 days.
