Microbiological air contamination in intensive poultry breeding

Intensive poultry breeding is, among others, characterized by considerable air contamination with microorganisms, dust, endotoxins and various gases, which can exert infectious, immunosuppressive, allergic and toxic effects on human and animal health. In the present study, the level of atmosphere contamination with microorganisms, dust and noxious gases was assessed during intensive chicken breeding. The chicken were kept in deep, 10-cm litter, at a population density of 20 chicken/m2. Study results showed gram-positive bacteria to predominate in the chicken housing, whereas the presence of gram-negative bacteria was considerably lower. The fungi identified in the housing atmosphere belonged to the group of saprophytes that constitute the normal microflora of animal housing.
