Human Intestinal Parasites
Microscopic protozoa, amoebae, parasitic worms and flukes are several human parasites. Humans might be contracted with protozoa and amoebae through food and water intake, animals, and human contact. When humans consume raw meat, they can get infected with parasitic worms easily.
Below are several human intestinal parasites that may attack us anytime:
Giardia lamblia is the protozoan parasite that lives in the small intestine or gall bladder. Water and fecal contamination are the means that may spread this human parasite quickly. You might find Giardia in unboiled water, so if you consume unboiled water, you might have stomachache or diarrhea.
Cryptosporidium refers to the protozoa that survive in the digestive tract leading to gastrointestinal infection. Like Giardia lamblia, cryptosporidium can infect you through raw foods and unboiled water intake. Diarrhea and stomachache are the common symptoms of cryptosporidium.
Necator americanus (hookworms)
Hookworms enter humans through water or fruits and vegetables. When you consume them, hookworms will cling to the intestine and feed on blood. Symptoms you may have include diarrhea, nausea, and stomachache.
