Answer 1

A parasite is an organism that depends on another organism (host) for their living. They normally attach to the host to suck blood, bowels or bodily fluids. Parasites enter our body through skin or mouth. eg. Protozoa-These organisms are single-celled and can live and multiply inside our body. An infection caused by protozoa is giardiasis which comes from drinking water infected with giardia. Some are very harmful that it can causes damage to the human body. Mosquitoes are most common parasites that attack humans for blood. Children who play outdoors in the dirt, close contact with pets etc. are more prone to parasitic infections. It can be found in foods also eg. undercooked or exotic foods.
Parasitic infections can be determined by blood tests or fecal samples. Home cleanliness is one of the best way to prevent from such infections. Washing hands oftenly and cleanliness can prevent parasitic infections and diseases. While coming to the prevention of internal parasite infections, two important areas need to be avoided--1.Grazing on pastures and areas with large populations of worm larvae. 2. pasture contamination with large populations of worm larvae.

Most of parasitic infections have no symptoms or symptoms are very mild. But a serious symptoms may occur i.e the infestation is large enough which leads to health problems. For such serious symptomatic cases, physician may advise drug to kill the parasite or may be to relieve it. For Pinworm infection an anti itch cream can help to relieve from itching. Other medications like mebendazole, pyrantel pamoate and albendazole are best use for killing worm infestations. The best method to prevent from parasitic infection is to keep clean, not only our body but also our household. So, frequently taking bath, cleaning clothes and bed sheets, wearing cleaned and ironed clothes are necessary for prevention.

Many tropical areas are highly affected with parasitic diseases. Example is the infections caused by protozoan parasites of the Trypanosomatidae family. It affected highly on human health. Another example is Leishmaniasis ( Leishmania sp) which is associated with poverty, and it becomes an endemic parasitic disease in most of the countries. Despite advanced treatment technology has been made in the last decade like chemotherapy, there is still lacking of an approved vaccine. Due to lacking of effective medication and significant drug resistance, it has made an inexpensive, efficient and safe agents. Example 1,3,4-Thiadiazole rings, a synthetic compounds and it is a bioisostere of pyrimidine or benzene rings.This compound has antileishmanial property. So, they are required for synthesis of future agents which is an alternative to the treatment of leishmaniasis.
