This article presents data demonstrating the contamination of temporary and permanent ectoparasites in birds sampled in the poultry houses with equipment directly from stock, for contamination with pathogens of infectious diseases, persisting in poultry farms. It proved to be transmissible infectious agent’s malofag poultry and red chicken mite.
When conducting microbiological research, homogenate were isolated as well as ectoparasites, establishing the following microbiological picture of separate cultures of Enterobacteriaceae – E. coli, staphylococcus – S. aureus, S. gallinarum, S. epidermidis, S. saprophyticus; streptococci – S. pneumoniae, S. faecalis. The homogenate of chicken mites allocated all of the above microorganisms, while culture homogenate contained malofag Enterobacteriaceae E. coli and streptococci – S. pneumoniae, S. faecalis. Our results indicate the great significance of ectoparasites in the spread of infectious diseases, since the release of poultry from parasitic entomofauna will reduce the risk of outbreaks among livestock effecting economic development.
As a result of this experiment it is shown that temporary and permanent ectoparasites of birds, in particular the red chicken mite Dermanyssus gallinae and mallofagb land birds (chickens and turkeys), selected in most poultry houses (Dermanyssus gallinae), and directly c birds (mallofag) are carriers of pathogenic coccal microflora: Escherichia, staphylococcus and streptococcus.

Key words: temporary and permanent ectoparasites of birds, insect contamination, biosecurity of poultry farms, the pathogens of infectious diseases.
