Dietary toxic infections occur everywhere, which is due to the widespread spread of these pathogens in the environment. The highest morbidity is observed in economically developed countries of the world.
Campylobacteriosis is characterized by polymorphism of clinical manifestations of infection. The most common form of infection is enterocolitis. Systemic lesions may also occur (septicemia, meningitis, cardiovascular disorders such as: thrombophlebitis, myocarditis, endocarditis, kidney and urinary tract, liver and gallbladder, nervous system: paresis, paralysis, polyneuritis, musculoskeletal system: arthritis , synovitis, bursitis) and neonatal pathology (septic abortions and preterm labor, accompanied by the development of septicemia, meningitis and enteritis in newborns).
A person under certain conditions (sick, reconvalescent) can be a source of infection, especially for people with immunodeficiency states and infants. The household route of transmission is realized in direct contact with animals (birds, especially chickens), in which often asymptomatic carriers of the pathogen are observed. The cases of transmission of the pathogen by contact-to-home means among family members or in specialized closed medical institutions are described, which is explained by the low infectious dose of the pathogen.
Due to the growing recognition that Campylobacter is an important intestinal pathogen in humans, the influence of widely used disinfectants on the sensitivity of isolates of this pathogen was studied.
A number of disinfectants are used to disinfect, but most of them have a narrow spectrum of bactericidal properties and are highly toxic.
The purpose of the work was the use of the method of test objects in the disinfection system in the fight against the causative agents of campylobacteriosis. poultry.
Materials and methods. An assessment of the effectiveness of disinfectants was carried out in accordance with P 4.2. 2643 -10 "Methods of laboratory research and testing of medical prophylactic disinfectants for assessing their effectiveness and safety.
Results of the research. The bactericidal activity was determined by the method using test objects. Working solutions of disinfectants were prepared ex tempore by mixing the appropriate quantities of disinfectants and sterile drinking water.
An analysis of the results of the studies presented indicates the ineffectiveness of using ultraviolet as an independent means of disinfecting surfaces of different types in exposures of 20 minutes and 2:00, which may be due to the "blind zones" of the room and the bacteriostatic effect of formalin with exposure 24-48 hours.
Conclusions and prospects for further research. So we can say that the use of ultraviolet as an independent means of disinfecting surfaces of various types contaminated by bacteria for exposures of 20 minutes and 2 hours ineffective is ineffective. In the long term, it is necessary to comprehensively approach the system of disinfection and adherence to sanitary-and-epidemiological rules in the fight against pathogens of food toxicoinfections.
