In Republic Kazakhstan it is widely distributed Listeriosis registered among people, agricultural animals, rodents and also birds. Listeria strains were isolated in various products, mainly an animal origin, including in the food stuffs ready to the use.

Materials and Methods: The material from patients for the period 1993–2003 is investigated. Properties 188 Listeria strains are investigated. Sensitivity to 21 antibacterial preparation L. monocytogenes strains of various origins is determined.

Results: For the period of 1993–2003 207 patients with laboratory confirmed Listeriosis diagnosis are revealed. Patients had various clinical picture and accordingly various diagnoses. In 7% of cases at patients contact to pets has come to light, connection of disease with foodstuff in 27% is marked: 2 families Listeriosis are fixed, in everyone were ill simultaneously on 3 members of families. Two patients had professional character of disease (women from poultry farm and men-farmer). Four cases of bacteriological confirmed Listeriosis of newborn are marked also.

The age structure of Listeriosis patients was from 1 month till 65 years, middle age has made 19 years. 30% from number of all patients have fallen to a share of children in the age of from 1 month till 14 years; 61% – on age from 19 till 40 years, 10% – on age from 55 till 65 years.

At research of material from people the percent of isolation Listeria from tests of pathological material was the following: from pharynx – 45%, from blood – 31%, from contents of initial skin affect – 14%, from urine – 10%.

Irrespective of source of isolation all cultures are submitted as L. monocytogenes I serovar. Cultures had typical cultural-morphological and biochemical properties, only some distinctions in ability or speeds of fermentation of separate sugars and spirits were marked.

Resistance to cephalosporins, sulfonamide, polymyxin, and lincomycin and nitrofurans preparation was (common for all investigated Listeria strains of various origins. The most active in relation to Listeria strains were amoxicillin, ampicillin, gentamycin, streptomycin, tetracycline and erythromycin.

Conclusions: Listeriosis infection has a wide distribution in Republic of Kazakhstan among people of various ages. Listeriosis strains basically have typical properties are submitted L. monocytogenes I serovars.
