Research Paper on Capillaria hepatica lifecycle and effects on human
On Capillaria liverleaf lifecycle and effects on human health - Research Paper ExampleIt will also dissertate the diagnosis, treatment and preventive measures of disease.Capillaria hepatica is a nematode that causes hepatic capillariasis in several mammals. Rodents were the first master of ceremonies to be described with the infection. Later on, it was discovered that the bloodsucker can infect various mammals including humans (Calle, 1991). Rodents be highly infectious explaining for the global spread of the infection. It has been reported in various countries with China having the highest prevalence of the disease. Until 2000, close 37 cases of human infections have been reported worldwide (Li & Hui-Lin, 2010). The symptoms are nonspecific thus, majority of the cases are misdiagnosed. The parasite causes hepatica capillariasis which is a serious infection of the liver. This occurs both in humans and animals.The bad parasite takes the regular(prenominal) shape of a nematode. The anterior fracture of the body is narrow while the posterior is broad. The adult womanish measures somewhat 60 mm long by about 0.20 mm wide and the male is about half as long (Bancroft, 1893). The esophagus occupies about half the body length the females and males a third. The ball are tapered at the poles. They measure about 0.51- 0.68 mm by 0.30-0.35 mm resembling those of Trichuris trichura. The dorsal part of the parasite has a copulatory sheath and spicule (Attah &Nagarajan, 1983). Humans get infected following the wasting disease of food and water contaminated with the embryonated eggs.The parasite requires only one host to mature from the eggs to the adult. The adult parasite lives in the liver of the host where they lay eggs in the parenchyma. The eggs are non excreted in stool rather they remain dormant until the host dies or the liver is eaten by a predator. These eggs are unembryonated thus are not infectious. They are passed through feces where they are embryon ated in the environment (Cox, 1993). Cannibalism plays a vital role in the
