Nippostrongylus Brasiliensis
''Nippostrongylus brasiliensis'' is a gastrointestinal roundworm that infects rodents, primarily rats. This worm is a widely studied parasite due to its simple lifecycle and its ability to be used in animal models. Its lifecycle similar to the human hookworms ''Necator americanus'' and ''Ancylostoma duodenale'' which includes five molting stages to become sexually mature. Lifecycle Eggs located within the soil release motile, free-living worms that must moult twice (L1 and L2) to develop into their infective L3 stage. This L3 stage can penetrate through intact skin in as little as 4 hours. Once inside the host, the worms invade the venous circulation and are carried into the lungs, where they become trapped in the capillaries. When the worms mature into the L4 stage, they rupture the capillaries and are released into the alveoli, where they are coughed up and swallowed. They then reach the small intestines 3–4 days after the initial infection. The worms become adults after the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nematodes
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over time.

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...
