The vector - the one carrying the disease-causing germ, and ; The host - where the infection will be infested too. The symptoms of parasitic infections depend on the parasite. Parasitic nematodes of livestock have major economic impact worldwide. Immunocompromised patients present with altered pattern, progression, and clinical manifestations of parasitic infections. Bedbug bites are often itchy so use an antihistamine cream to prevent scratching and potentially infecting the bite. Arthropods, the third, aren't parasites themselves, but these insects and spiders are common hosts of parasitic diseases. Examples of Parasitism.
