many water sources in the wilderness include microorganisms‚ bacteria‚ viruses and contaminants. 1. Boiling * Boiling water is the most effective way to kill all disease-causing microorganisms‚ such as E. coli‚ Cryptosporidium and Giardia lamblia‚ which are present in lakes and rivers. Depending on your elevation level‚ you should boil water for different lengths or time. Water temperatures above 160° F kill all pathogens within 30 minutes and above 185° F within a few minutes.

organisms Host-parasite interactions often operate over a longer timescale than those seen with other pathogens Results in significant host-parasite interaction at the cellular and organismal level E.g. Parasites that alter the behavior of the host Giardia lamblia – induce biochemical change in the host cells at the site of infection (duodenal epithelium) Parasites – have life cycles that often involve several hosts (survival and transmission between different hosts requires the parasite to exhibit more

nails. A common yeast infection is thrush caused by Candida albicans. Protozoa: are microscopic organisms‚ but larger than bacteria. Free-living and nonpathogenic protozoa include amoebae and paramecium. Examples of medical importance include: Giardia lamblia‚ which causes enteritis (symptoms of diarrhoea). Worms: are not always microscopic in size but pathogenic worms do cause infection and some can spread from person to person. Examples include: threadworm and tapeworm. Prions: are infectious protein

What is Food Microbiology Food microbiology is the study of food micro-organisms; how we can identify and culture them‚ how they live‚ how some infect and cause disease and how we can make use of their activities. Microbes are single-cell organisms so tiny that millions can fit into the eye of a needle. They are the oldest form of life on earth. Microbe fossils date back more than 3.5 billion years to a time when the Earth was covered with oceans that regularly reached the boiling point‚ hundreds
