Acaroid mites belong to the kingdom of arthropod, class of Arachnida (Acari), Acarina (Acaridida), including a total of 7 families of Acaridae, Demodicidae, Arrenuridae, Chortoglyphidae, Carpoglyphidae, Pyrogyphidae and Histiostomatidae. Grain or flour mite is a serious and widespread pest of stored foodstuffs, particularly grain and grain products. They are small creatures of about half a millimeter in body size and creamy white in color, very difficult to detect in drugs and food products. The incidence of various forms of human acariasis caused by the ingestion of mite-infested food is unusually high in China.
Diarrhea, abdominal pain, burning sensation around anus and other symptoms of gastrointestinal tract may result from ingesting food or drugs contaminated acaroid mites: Dermatophagoides farinae (house dust mite), Dermatophagoides pteronyssinus (house dust mite that causes allergic disease in dogs as well as in humans), Glycyphagus domesticus (storage mite, also known as Furniture mite), Tyrophagus putrescentiae (a dominant species of Storage mite in Korea, is a particularly important cause of allergic disorders in this country), Carpoglyphus lactis (stored product mite infesting saccharide-rich stored commodities including dried fruits, wine, beer, milk products, jams and honey), Tarsonemus granarius (feeds on and disseminates fungi that deteriorate grain stored for prolonged periods).
Acaroid mites are able to parasitize in human intestines. Like other intestinal parasites, the mites living in intestinal tract may damage intestinal tissues with their mouthparts and feet. Certainly they may also intrude into mucous and deep tissues and cause inflammation and necrosis. Diagnosis is made based on stool and urine. Patients with mites in stool samples develop allergic reactions. Skin prick test is one of the specific methods for clinical diagnosis of allergic disease.
Diarrhea caused by acaroid mites is associated with the patient's occupation. Acaroid mites are frequently found in rice storehouses and flourmills, suggesting that the source of diarrhea caused by acaroid mites is mites in our living environment and stored food. However, some mites in dust or in air might invade intestine through mouth or nasal cavity.
Secretions of acaroid mites are strong allergens that cause a variety of human allergic diseases, such as allergic asthma, allergic rhinitis and skin rash. Of these disorders, the mite's allergic asthma, a chronic airway inflammatory disorder, can be greater risks to human health.
