This sets them apart from most other worms, which usually enter through the stomach. They usually live in human feces, and that is how they are transmitted to humans, they walk through, sit, or lie in contaminated dirt, and the worms transfer to their human hosts. They travel through the blood vessels to the lungs, where they can cause shortness of breath and coughing, and then they move on to the throat, where the host swallows them and they flow to the small intestine. They can grow to about .4 inches long, and they suck blood out of the walls of the intestine, which can cause anemia and abdominal pain. They mostly affect people living in African, China, Southeast Asia, and Latin America, and the World Health Organization believes that as many as 740 million people suffer from hookworm (Ballantyne, 2010). They are treated with medications that are extremely effective and have few side effects. Sabin Vaccine Institute is currently conducting extensive research into developing a hookworm vaccine that could wipe out the disease. They received funding from...
They are working to eradicate the disease because it is so prevalent in poor, third-world countries. They are working in conjuncture with several other agencies to come up with a cure. There are no benefits associated with these worms. The worm is a nematode, so it creates its own environment, and does not beneficially affect the worm or its environment at all.
Search of the Perfect Host The Origins and Specificity of Parasites The door opens. You walk into the room. You hear your favorite music. You see your best friends. Your favorite drink is waiting on the bar. Smiling, the hostess approaches, "I did it all for you." Ah, what a dream - the perfect party, the perfect host! While such a fantasy may not always be the lot of the human
The morphological properties of the virion are non-enveloped, with isometric Necleocapsids 27 nm in diameter. The symmetry is icosahedral, with the Nucleocapsids round in shape. Further, there are 12 capsomers per neucleocapsid (ICTV). Additionally, the virions each hold one molecule of linear positive-sense single stranded RNA, with a total genome length of 7500 nt, and a hairpin structure (ICTV). Treatment and Prevention: The impact of the Hepatitis a can vary from
These proteins include homologous members of yeast. The presences of these proteins suggest that E. histolytica is skilled to perform homologous recombination, which is the same as in other organisms. DNA damage was evaluated by TUNEL assay. In yeast and in human cells, histone H2AX becomes rapidly phosphorylated when DSBs are introduced into chromatin (Lavi et al.). Studies show that histone as a protein plays a significant role in the
In "Piaf," Pam Gems provides a view into the life of the great French singer and arguably the greatest singer of her generation -- Edith Piaf. (Fildier and Primack, 1981), the slices that the playwright provides, more than adequately trace her life. Edith was born a waif on the streets of Paris (literally under a lamp-post). Abandoned by her parents -- a drunken street singer for a mother and a
Elderly Population With Diabetes AGE MATTERS Elderly Diabetes Epidemiology: Definition and Description Epidemiology is the study of the distribution and factors to health conditions in particular populations and its application to the control of these health conditions (NCCDPHP, 2004). The shortest description of the work of epidemiologists is that they count and compare data of cases of disease or injuries in a given population. Then they compare these data with those of another or
Agricultural Assessment Economics of Production and Resource Management: Assessment of the Environmental Impact Associated with Human Waste Fertilizer in Agricultural Production The objective of this study is to conduct an assessment of the environmental impact associated with human waste fertilizer in agricultural production. National Geographic News reporter Tasha Eichenseher reported that 200 million farmers in developing countries are making use of raw sewage due to water shortages and rising costs of fertilizer
