You will prepare and submit a term paper on Infectious Agent In Terms of its Microbial Classification. Your paper should be a minimum of 1500 words in length. Shigella bacterium does not show any sort of symptoms even after the propagation, rather it spread from one person to another person more before resolving completely. In general, Shigella bacterium takes 5 to 7 days to resolve completely (Blostein, 1991). The propagation of Shigella bacterium can be controlled by incorporating hygiene measures and medication. At the same time, the human can protect or reduce the chances of attack of the Shigella bacterium on their body by adopting caution steps such as frequently washing the exposed organs of the human body (Blostein, 1991). The following picture highlights the structure of the Shigella bacterium.

From the above picture, it can be defined that there is a variety of Shigella bacterium observed in the environment such as ‘Shigella sonnei’, which is also acknowledged as a ‘Group D’ in the United States. Similarly, ‘Shigella flexneri’ is also known as ‘Group B’ Shigella. According to the report published by Centers for Disease Control and Prevention (2014), Shigellosis usually transfers into the human body via drinking water or it can be also transmitted by food in human body (Centers for Disease Control and Prevention, 2014. Sureshbabu, 2012).

The investigator identifies a couple of potential sources of infection in the outbreak such as ‘Shigella sonnei’ and ‘Shigella flexneri’. On the other hand, one of the potential sources not identified in the outbreak is ‘Shigella dysenteriae’. In this regard, it can be asserted that ‘Shigella dysenteriae’ is one of the rare potential sources of infection, which is especially observed in the United States. This special type of ‘Shigella dysenteriae’ bacteria can spread from an infected individual, through contained water or food. Apart from this, the infection can also spread from the stool of the infected person. In this context, it can be asserted that slight intrude of Shigella bacterium in the human body can cause symptoms&nbsp.and disease for an individual.
