Nematology is the study of nematodes, also known as roundworms, which first began in the nineteenth century. Like many fields of study, nematology began with ancient recordings and descriptions lacked elements of modern science. The oldest record of a nematode occurs in the Pentateuch in the fourth book of Moses known as Numbers. The reference, although not plainly stating roundworms or nematodes, is thought to refer to Dracunculus medinensis, a species that is native to the area near the Red...
Trichuris suis is a species of whipworm that is classified within the Nematoda phylum. It can be found in warm tropical regions throughout the world but is rare in arid regions. Males reach an average body length between 1.1 and 1.5 inches, while females reach an average length between 2.3 and 3.1 inches. This species, and other members of the Trichuris genus, was given its common name because of its whip like appearance. The original definitive hosts of this species are pigs, but it is able...
Phasmarhabditis hermaphrodita is a species of roundworm that is classified within the Nematoda phylum. This species is found in soils where slug species from the Limacidae, Arionidae, and Milacidae families are located, with one common host being Deroceras reticulatum. The worm can be located in soil by using real-time PCR testing methods, a test that also distinguishes it from its similar relative, Phasmarhabditis neopapillosa. The life cycle of Phasmarhabditis hermaphrodita begins in...
Onchocerca volvulus is a species of roundworm that is classified within the Nematoda phylum. This species causes the disease onchocerciasis, more commonly known as river blindness. The life cycle of this species is dependent upon an intermediate host, typically the black fly, and a definitive host, which is always a human. Its lifecycle begins when a black fly ingests microfilariae from a human host by consuming blood. The microfilariae that were present in the skin of the human host now...
Trichinella spiralis, sometimes known as the pork worm, is a parasite within the Nematoda class. It can be found in pigs, rats, humans, and bears. This worm causes trichinosis in humans, most often from consuming undercooked pork. This species is the smallest within its class, reaching an average body length of .16 centimeters. Females are twice as large as males, displaying a sexual dimorphism. The reproductive organs of females are unique to the species in that the front end holds developed...
