hoped to become more respected if he became more like Hall who experienced greater success. Fischer’s determination to be someone drove him to push himself beyond his threshold; while climbing Annapurna massif in Nepal, he became infected with Entamoeba histolytica, which results in sweating spells and the shakes (Krakauer 210-211). Fischer rarely revealed his condition, due to
bloodstream. Liver abscesses often cause abdominal pain, fever, and other symptoms. A liver abscess can be dangerous if not treated. CAUSES This condition may be caused by a bacterial infection or infection with a parasite called an amoeba (Entamoeba histolytica). In rare cases, it can also be caused by infection with a fungus called Candida. Many liver abscesses occur when infections spread to the liver from other parts of the abdomen, such as the appendix (appendicitis), the
Cryptosporidium oocysts, Entamoeba histolytica & Giardia lamblia cysts) and bad hygiene,r exposure to contaminated soil that transmit the larvae and eggs of parasitic helminth (e.g. Hook worms & Trichuris trichuira) or getting infections after insects' bites in raw wild environment as
water treatment is a disinfection. During this stage, disinfectants will be added to kill or inactivate microorganisms that can cause disease in humans. The research on the water sample shows presence of protozoa that cause diseases such as Entamoeba histolytica, Giardia lamblia and Naegleria fowleri (Nemerow, Agardy, Sullivan, & Salvato, 2009). Some protozoa and viruses, which may present in water supplies are extremely harmful. There are two kinds of disinfection which is primary disinfection and
Gastroenteritis, sometimes referred to as infectious diarrhoea is a common disease that affects millions of people annually. It is a disease caused by viruses, bacteria or parasites that enter the human body and spread, which induce symptoms such as vomiting, diarrhoea, abdominal pain and nausea. Although it is a common occurrence in society and is usually not harmful, cases of gastroenteritis in less developed countries may have more fatal repercussions due to their inability to access ample means
In today’s society water quality and the possibility of contamination is a major concern. Humans use water to conduct daily activities and it is an essential resource. The world relies on a safe water supply that is potable and pathogen-free. Many countries, like the United States, have made a large effort to make water safe to drink with complex filtration and purification systems. These systems seem to be a given in many first world countries and people don’t have to worry as much as those in developing
marine environments and the soil. Protozoan infections are parasitic diseases caused by organisms formerly classified in the Kingdom Protozoa. They include organisms classified in Amoebozoa, Excavata, and Chromalveolata. Examples include Entamoeba histolytica, Plasmodium (some of which cause malaria), and Giardia lamblia. The symptoms of protozoan infections depend on the type of single-celled parasite involved and where in the body it lives and multiplies. These types of parasites are referred
INTRODUCTION Helminthes in the field of microbiology refers to all groups of parasitic worms namely; cestodes (tapeworms), tremadodes (flukes) and nematodes (round worms). Soil transmitted helminthes refers to a group of parasitic diseases in humans transmitted through contaminated soil. These infections are caused by round worms such as Ancylostoma duodenale , Necator americanus, Ascaris lumbricoides, and Trichuris trichuria. Soil transmitted helminthes diseases have become the most common parasitic
Soil-transmitted helminthes, also known as intestinal worm infections. It is one of the most common parasite infections in the world. These infections are most prevalent in tropical and sub tropical regions of the developed world where adequate water and sanitations are lacking. Recent estimate suggesting that A. lumbricoids infects 1,221 million people, T.trichuira 795 million, and hookworms 740 million (Desilva et., 2003). Chronic and intense soil transmitted helminthes can contribute to malnutrition
