Parasites

Every year, more than 1 million people die because of diseases caused by parasites due to malaria. 2 million new cases appear, despite worldwide effect to control the disease. The current situation is now more complex and difficult to solve than ever. Parasite, although still microscopic, and most favorably seen under a zoom microscope are generally larger than bacteria and possess a more evolved cell structure. They include the amoeba that causes amoebic dysentery. Malaria is caused by parasite and can be transmitted through the bite of a mosquito. Destruction of red blood cells causing fever and anemia are some of the characteristics of malaria.

All efforts at controlling the disease focus on the mosquito that is the carrier of the malaria parasites. A person catches malaria when bitten by a female mosquito. The parasite may then stay dormant in the human liver for months or even years before causing symptoms. There are different types of malaria, some more likely than others to be fatal. The control of the mosquito population helps control the disease. Drugs can be used to treat infected humans, and measure –such as the use of nets, repellants, and suitable clothing can be taken to prevent mosquito biting.

Parasites are divided into three groups- protozoans, worms and arthropods.

Parasites like protozoans are not damaged by antibiotics in the concentrations that would be lethal to bacteria. Some, such as malaria parasite, go through complicated life cycle. It is important to test for parasites for accurate treatment and diagnosis because some indication of parasitic infection is alike.

The stool sample are being examine under a zoom microscope in the laboratory to test whether the sample stool are infected or not. To examine the sample the stool is spread thinly in the slide and put a drop of solution then cover with another slide. Placing in the stage of the zoom microscope and adjusting the center to the center to clearly view the specimen.

Other groups of parasites are worms. Parasitic worms affect human intestines in various ways, and in some cases migrate to various other organs of the body, sometimes causing large cysts or swelling of limbs as in elephantiasis. They include threadworms, roundworms, hookworms, flatworms, flukes and tapeworms. These parasite worms can only be seen also under a zoom microscope.

Arthropods which are also under parasitic group not only infest or infect humans, but some also act as carriers of microorganisms, such as those that cause plague. This includes lice, fleas and mites. To avoid any parasites entering our body which can infect us, we should see to it that anything we eat and drink is clean. As much as possible avoid eating food that is exposed to dirt. We should also remember that not only food and drinks can be the host or the only carrier of parasites. Our pets most especially cats can also be a carrier. Pets should have their own area and should always be clean. And a regular visit to the vet will ensure both you and your pet stays healthy.
