Bacteria and Human Health and Viruses and Humna Health - Research Paper ExampleA single E-Coli bacterium organism can replicate itself to the extent equaling the mass of earth within 24 hours if left unchecked. The bacteria come in miscellaneous sizes and shapes. The shapes range from coccal (spherical), bacilli (rods), vibrio (curved rods) and spirochetes (spirals) (Richard Robinson Ed. Biology 4 Volume Set).The role of bacteria in human health has been both positive and negative. A bacteria organism can be infections and beneficial as well. Although bacteria are mostly known for the harm that they bring to human clay, there are scarce some bacteria that really put a bad effect on the human body (Sheela Srivastava. Understanding bacteria). There are two situations by dint of which the bacteria can put an affect on the human body one is through infection and second as affection. Most of the times these both are considered synonymous, which in reality is not correct. Infection i s caused when a microorganism makes the human body is its host for result and nourishment. In most cases, the infection leads to disease but not always. An infected person may not necessarily be diseased. On the other hand, in a diseased state, the human body suffers (Paul Singleton. Bacteria in biology, biotechnology, and medicine). Primarily it was not believed that bacteria can be a cause of a disease in the human body because of already presence of many bacterial organisms in the human body working for the benefit of human being. There are more than 500 species of bacteria in the human body and most of them are useful for many functions that take place in the human body. There are chances that due to some conditions, the growth of bacteria becomes harmful to the body, it is the when a bacteria is said to be transformed into a pathogen. A pathogen is a microorganism that causes the diseases in the human body (Stuart Hogg. inborn microbiology).There quite a few bacteria which ar e pathogenic in nature and one of the most
