How Helminths Are Parasitic Worms

Improved Essays
Helminths are parasitic worms that harm the gastrointestinal tracts of humans, livestock, and wildlife. The infections are influenced by the environment (survival of the helminth’s infective stages), hygiene (infection through feces or urine), food preparation (undercooked meat), and contact with vectors (exposure to the necessary vectors) (Hotez et al., 2008). The worms are large and can migrate throughout the body to damage the host’s tissues or their metabolism (Wakelin, 1996). Helminths could interfere with the host’s digestion of food in the gut by causing infections with harmful symptoms such as internal bleeding, loss of appetite, and loss of iron (Mutapi, 2015). Helminths prevent host defenses and find their way to increase their survival

    What Is Komodo Dragons?

If the prey is large, the lizard tackles its legs first to nock it down, as their long claws dig into the body, then quickly rips into the body (as animal bleeds to death). They have been known to take down adult water buffalo weighing over 1,300 pounds.…
