Bacterial pathogens and synantropic mites represent an important human health risk related to food-safety and security. The allergens produced by stored-product mites are introduced into the food chain directly by mite bodies as well as in mite feces. Several recent studies indicated that some of the allergenic proteins are of a microbial origin. We previously observed and identified a wide spectrum of bacteria in the gut of synantropic mite species. There is a likely possibility that these bacteria produce the aforementioned human allergens. In addition, synantropic mites disseminate the gut associated bacteria in their feces leading to stored-food contamination. The proposed project is focused on the investigation of the mite-bacterial association and resulting human health hazards in stored-food commodities. The aim of the proposed research project is to investigate the role of the gut microbial community of stored product mites in the production of the human allergens as well as to assess the imp (en)
Identifikace druhových spekter bakterií izolovaných z trávicího traktu roztočů. Porovnání populací bakterií v různých druzích roztočů. Zjištění míry toxicity antibiotik pro roztoče a jejich asociované mikroorganismy.
Byla provedena identifikace druhových spekter bakterií izolovaných z trávicího traktu roztočů. Porovnali jsme populací bakterií v různých druzích roztočů. Zjistili jsme míru toxicity antibiotik na roztoče, prokázali jsme, že subletální dávky antibiotik v dietě mají malý vliv na spektrum asociovaných bakteriív roztočích. Výstupem projektu jsou vědecké publikace, všechny recenzované, sekvence. (cs)
We identified the bacterial community in digestive tract and internal tissues of mites. We compared the communities of bacteria among different species of mites. We observed the suppressive effect of antibiotics after their incorporation to the diet of mites. The antibiotic treatment of mites has low effect on associated microbial community. The outputs of the project are scientific papers. (en)
