I need some assistance with these assignment. define the major flora of the different regions of the human body and discuss the methods employed in preventing both exogenous and endogenous wound contamination Thank you in advance for the help! Major Flora of the Human Body Major Flora of the Human Body The human body is covered with skin, which amazingly has millions of microorganisms that reside in it (Rello & Kolleff 2007, p. 76). All these microorganisms are non-pathogenic, which means that they are either beneficial to the human body, or are of no consequence. Their presence guarantees that the human body functions at full capacity without any hindrance from existing forces or external forces (Crossley, Jefferson & Archer 2009, p. 89). Their functions include. competing with pathogenic microorganisms for nutrients, secreting certain chemicals to counter their harmful chemicals, and even stimulate the immune system. The mutualistic tendencies these microorganisms exhibit aid in the protection of the individual’s immune system, respiratory system, and even gut (Price & Frey 2003, p. 67). This is especially when it comes to fighting off pathogens. However, they can also cause diseases when not properly monitored.

Exogenous and endogenous infections occur as a result of the presence of these microorganisms. Exogenous infections occur when pathogens enter the body through portals such as the respiratory, intestinal, and even reproductive areas. Endogenous infections often occur as a result of the patient’s distorted resistance (immune). Some of the methods implemented to deal with exogenous infections include. sterilization, cleaning, and disinfection (Gruendemann & Mangum 2001, p. 43). In doing some of these operations, it is easier to reduce the manner in which an individual is exposed to a harmful external environment. A technique used to deal with endogenous infections includes. skin preparation, where the patient undergoes thorough screening to determine whether the skin may act as a contaminant or not. Antibiotic prophylaxis is also another method where the surroundings of the patient are treated to reduce or eliminate contamination (Gloster 2010, p. 57).
