decreased‚ this has not been fully successful just yet. Successful eradication of parasites would involve educating the people‚ proper sanitation‚ and the compliance of the public to the guidelines provided by the government and health organizations. This is not an easy matter for these require much time and money and people from rural areas have been used to their way of life and some do not see how the parasites may cause harm and affect one’s performance.

Roundworms (Nematodes) All grazing horses are infected with nematodes according the American Association of Equine Practitioners (2013). However‚ the impact on the health of the horse depends on the level of infection. Understanding how these parasites interact with the environment and host is crucial to finding ways on how to control them. Nematodes form three life-cycle stages: eggs‚ larvae (which undergo four metamorphoses) and adults. (Adapted from University of Liverpool (n.D.) ) Equine

These options allow us to eliminate chemicals‚ microorganisms and disease from water such as cholera‚ e-coli‚ cryptosporidium‚ giardia‚ enterovirus‚ and many more including metals. There are pros and cons to both treatment processes and we will go over them in the next few paragraphs. Chlorine is the widest used process in water disinfection. Used by water municipals‚ as well

More specifically the sub-Sahara region. Human African Trypanosomiasis is one of the most neglected tropical infections that is re-emerging as a public health issue in most parts of rural Africa. It is caused by a protozoan called trypanosome brucei‚ which is a sub species of the trypanosome parasite. The vector-borne

By definition‚ a parasite is an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host’s expense. This relationship will always negatively impact the host and benefit the parasite‚ but the host is vital for the parasite to stay alive. An example of a parasitic relationship is when a tick latches onto a cat. This form of parasitism is external and the tick sucks on the cat‚ fostering due to the grace of the cat’s oblivion‚ and because of this exchange

Three terrifying parasites with one thing in common: they are even more dangerous dead than alive was the primary focus of this episode. It is often when the parasites die that a host will then realize they even had an infection but by then it can be too late. The first victim felt nauseous and cramping. Doctors had discovered a mass on the victim’s stomach that was causing the blockage. There were fragments of a worm inside of this mass and the doctors had found that the victim had eaten raw fish

preditation in the sense that the parasite derives nourishment from the host on which it feeds and the predator derives nourishment from the prey on which it feeds(Nitecki 1983). Parasitism is different from most normal predator prey situations because many different parasites can feed off of just one host but very few predators can feed on the same prey(1973). In parasite-host relationships most commonly the parasite is smaller than the host. This would explain why many parasites can feed off of one single
