Hookworms are parasites. This means they live off other living things. Hookworms affect your lungs and small intestine. Humans contract hookworms through roundworm eggs and larvae found in dirt contaminated by feces. .
Symptoms include abdominal pain, colic (cramping and excessive crying in infants), intestinal cramps, nausea, fever, blood in your stool, appetite loss, itchy rash.
Most cases of classic hookworm disease can be managed on an outpatient basis with anthelmintic and iron therapy, complemented by appropriate diet. Patients with anemia and malnutrition may require both iron supplements and nutritional support (including folate supplementation). Some patients with severe anemia and congestive heart failure may require hospitalization.
The oxygen consumption of the free living 3rd stage larva of Necator americanus and the conditions affecting this were studied using manometric techniques. It was found to decrease during storage of the larvae at a rate related to the length of time they were stored and the temperature at which they were maintained. An increase in temperature caused an increase in the oxygen consumption.
