Bacterial Pathogenesis

ABSTRACT If a micro being either harms or lives at the write off of a nonher organism, it is c aloneed a leechlike organism and the relationship is called the parasitism. In this relationship the infected organism is referred to as boniface. Those organisms capable of do distemper argon called pathogens. complaint is any change in the forces from a healthy to an unhealthy,abnormal statein which die or all of the hosts body is not capable of carrying on its normal functions. The steps of the infecting plow involving bacterial disease commonly include the following : * The bacterium is transmissible to suitable host , * Attaches to and/or colonises the host, * Grows and multiplies inside or on the host * Interferes with or impairs the normal physiological activities of the host During coevolution with clement hosts,pathogenic bacteria have evolved interlinking signal transduction pathways to regulate the genes requisite for virulence. The genes that encode virulence factors are often located on large segments of DNA within bacterial genome.called pathogenecity islands that carry genes accountable for virulence. Two distinct categories of disease can be treasure based on the eccentric bacteria play in disease causing process : * Infections(invasion and growth) * intoxications .

Toxins produced by pathogenic bacteria are either exotoxins or endotoxins. Viruses and bacteria are unceasingly evolving and producing unique mechanisms that enable them to fudge the hosts arsenal of defences. The modern era of chemotherapy began with c apital of Minnesota Ehrlischs serve on drug! s against affrican sleeping sicknessand syphills. Other pioneers were Gerhard Domagk, horse parsley Flemming, Howerd Florey etcetera Many infectious diseases are treated with chemotherapeutic agent, much(prenominal) as antibiotics, that inhibit or kill the pathogen while harming the host as little as possible. Ideally, antimicrobic agents disrupt microbial processes or structures that differ from...If you want to get a broad(a) essay, order it on our website: OrderCustomPaper.com
