Microbiological Air Contamination in Poultry Houses
Since intensive poultry production is accompanied by as high as possible densities of birds within buildings, this exposes poultry house workers to elevated concentrations of bioaerosol that is mainly emitted by birds. Exposure to dust containing pathogenic microbial and parasitic agents may cause asthma, asthma-like syndrome, mucous membrane irritation, chronic bronchitis, and allergic alveoli...
متن کاملRisks caused by bio-aerosols in poultry houses
Aerial pollutants in confined animal houses are widely recognized as detrimental to the respiratory health of animals kept in these facilities. Primary and opportunistic microbial pathogens may directly cause infectious and allergic diseases in farm animals, and chronic exposure to some types of aerial pollutants may exacerbate multi-factorial environmental diseases. There are, however, few int...
متن کاملUltra Sonic Sprayer Controlling Dust in Experimental Poultry Houses
Dust control tests of experimental enclosed layer and floor feeding broiler houses were performed with ultra sonic sprayer units which have some advantages such as 1) low cost, 2) low electric power consumption, 3) forcing the charge and 4) unnecessary to lay pipes to spray. With spraying 2 % solution of emulsified canola oil in layer house, the concentration of dust with aerodynamic diameter (...

متن کاملDiversity and habitat specificity of free-living protozoa in commercial poultry houses.
Despite stringent biosecurity measures, infections by bacterial food pathogens such as Campylobacter are a recurrent problem in industrial poultry houses. As the main transmission route remains unclear, persistence of these infections has been linked to bacterial survival and possibly multiplication within protozoan vectors. To date, however, virtually no information is available on the diversi...
