Compose a 1250 words assignment on main characteristics of wuchereria bancrofti. Needs to be plagiarism free! The present research has identified that Nematoda phyla are members of the superphylum group aschelminthes of the class secernentea. the subclass spiruria and the order spirurida. The suborder is the spirurina. Nematodes are roundworms and one of the most diverse of all animals with over 28,000 having been described, of which 16,000 are parasitic. Secernentea is the main class of nematodes which are characterized by an excretory system and no circulatory or respiratory system (Secernentea). Spiruria, spirurida, and spirurina are parasitic nematodes belonging within the superfamily filarioidea of the family filariidae. Filariidae contains a total of six genuses, brugia, filaria, ichthyonema, onchocerca, parafilaria, and the genus wuchereria, the specific name being bancrofti and the scientific name wuchereria bancrofti. W. bancrofti have eight circumoral papillae forming two circles, an inner and an outer and two lateral amphids, with an unpaired papilla anterior to the cloacal aperature in the male. Only the males contain cuticular striations on the ventral surface which are anterior to the cloacal aperature. The distal end of the right spicule is a heavily cuticularised subterminal triangular piece and the female tail has minute cuticular bosses on the left side which are posterior to the anus and there is also one phasmid. Ultrasonography visualization of the filarial worms usually shows them in a nested pattern with the worms viewed as wavy bands. The vector of W. bancrofti is the mosquito culex quinquefasciatus and the parasite is spread through the bite of the mosquito and is carried from person to person in countries that are subtropical and tropical. A male and female W. bancrofti will mate within the lymphatic vessels and the female will create thousands of microfilariae within the bloodstream.
