To identify parasitic forms that are recognizable in the fecal samples and blood smears by microscopy. 3. To determine the advantages and limitations in each procedure. II. Methodology Before the activity of checking or detecting the presence of parasites to the stools‚ it was started with getting a stool samples from the grade

I. Soil-Transmitted Helminthiasis Parasitism is a symbiotic relationship in which one organism‚ the parasite‚ benefits at the expense of the other‚ the host. Soil-transmitted helminthiasis is a human infection of the intestinal tract caused by different species of parasitic worms acquired through contact with contaminated soil (Bethony et al. 2006). Light helminth infections are well endured by human hosts and usually have no symptoms‚ but some serious cases cause morbidity and mortality (CDC‚ 2013;

Following ingestion‚ the mature cyst passes through the stomach and into the small intestine. Excystation occurs in the lower ileum‚ when the cyst develops into the trophozoite form.

toxoplasmosis is a protozoan parasite first discovered in 1908 and named a year later. Its medical importance remained unknown until 1939 when Toxoplasma gondii was identified in tissues of a congenitally infected infant‚ and veterinary importance became known when it was found to cause abortions in sheep in 1957. The discovery of Sabin-Feldman dye test‚ a toxoplasma gondii specific antibody test‚ in 1948 led to the recognition that Toxoplasma gondii is a common parasite of warm-blooded hosts with

Introduction Zoonotic intestinal parasites are prevalent around the world. One of the most common and studied is transmitted by the microscopic protozoan‚ Giardia intestinalis‚ also known as G. lamblia and G. duodenalis (Ivanov‚ 2010). This eukaryotic parasite is responsible for the transmission of the most common waterborne disease‚ giardiasis‚ which causes watery diarrhea‚ vomiting‚ and has even been linked to irritable bowl syndrome (Ankarklev et. al. 2010). Since its discovery in 1681‚ Giardia

But concerns still remain over the potential threat of the emergence of the parasites that are resistant to praziquantel.

Biology of STHs and transmission The life cycles of the major STHs i.e. hookworm‚ A. lumbricoides and T. trichiura have many features in common. The adult parasites inhabit the human intestinal tract. For hookworms‚ humans acquire the infection when third-stage larvae in soil penetrate their skin while for A. lumbricoides and T. trichiura‚ infection takes place through the oral route by contaminated food and water.

Species found in the genus Cryptosporidium are protozoan parasites that cause diarrheal disease with a global distribution. They mainly affect children‚ causing a self-limited diarrhea in healthy individuals; nevertheless‚ in people with acquired immunodeficiency disorder or AIDS‚ the disease can be quite severe and result in weight loss or malnutrition. Intestinal cryptosporidiosis continues to be an important public health concern worldwide‚ most notably through outbreaks caused by contaminated
