There are many dissimilar types of kinship that the body caninduce with the microflora. These are:1-MutualismIt is a “mutual benefit”, as bothorganisms get benefit from association from each other. For instance, E. colisynthesize and secrete vitamin K and B12 which is profitable for host. In return,E. coli gets warm & nutrient and moist rich environment for its bettersurvival.2-Commensalism:In this type of association, one organismgets benefit while the other is neither benefited nor harmed.
Bacteria have nocommensalism relationships with human beings. If bacteria present in our bodyor on the body, they play a role which is either beneficial (antagonism ofmicrobes) or harmful.Opportunistic(Pathogenic):E.coli is present in the digestive tract of human and other organismswhere it causes no harm and consequently no disease. But when it enters intothe urogenital tract of organisms, it may be harmful (pathogenic).Staphylococcusaureus is a bacterium of nose microflora found in the upper portion ofrespiratory tract.
If it gains entry into the cells by any wound or bleeding orburn it becomes harmful may be pathogenic. (https://www.slideshare.net/amanullah9803150/microbial-floraofthehumanbody) Characteristicsof the MicrofloraThe Microflora exhibit certain characteristics. These are:Notdisease-inducing:The microflora are also known as Microbiota and are not typicaldisease causing micro-organisms found in and on healthy individuals.Veryabundant:The microflora are extremely abundant in terms of sheer numbers.For instance, an ordinary human has approximately 1013 body cells and 1014individual microflora.
Allfound externally:Microflora are found more often than not on the skin, eyes,nose, oral fissure as well as on the throat and lower parts of the urethra andthe large intestineBenefits of microflora:a. Preventing colonization by microbial anatgonism competingwith nutrients and space and produce toxic condition or environmental conditionto keep harmful pathogens away (acidity in vagina).b. Develop immune system by keeping it active by providingantigens. (https://quizlet.com/7646560/normal-flora-flash-cards/)c. Microfloraare essential for us to survive.
d. Theygain their food from the stuff in our pie hole.e. If coloniesof bacteria are worn out by poisons or antibiotics, they must be replacedotherwise we would die ultimately. (https://www.quora.com/What-are-the-benefits-of-normal-flora)f. They provide a hostdefence mechanism by taking control on ecological niches for bacteria, e.
g. the intestinal villi.g.
Bacteria produceand excrete various compounds like vitamin B12 and vitamin K in the intestinewhich are important nutrients for host.h. The oral microfloraassist in immunity through inducing low level of circulating and secretory antibioticsthat kill pathogens. In other words, they enhance body’s immunity.i. The oral bacterialflora kill nonindigenous species by producing inhibitory fatty acids, peroxidesand bacteriocins (it is a protein and bacreria produce it, it helps in stampingand killing microbes).

Microflorahelp to digest food as they break down foodstuffs that are normallyindigestible by the host into forms that are easily digestible by the hosts.k. The Microfloraprotects the host from infection by harmfulpathogenic organisms.l. They produceantibacterial substances as by product of metabolism, so they have a localantibiotic effect which retard the attack of invaders on host.m.
Theystimulate an immunological response (an antibody-mediated immune response) asthey act as antigens in the human body. (https://www.ukessays.com/essays/biology/normal-flora-and-their-benefits.
php)Disadvantages of microflora:a. Microflorais harmful when overgrown (i.e. use of antibiotics) and misplaced (i.
e. urinarytract flora may placed with facel flora). (https://quizlet.

slideshare.net/amanullah9803150/microbial-floraofthehumanbody)Conclusion:There are few limitations of microflora to the human body aswell. For example, most of the microflora are pathogens and may causeinfectious diseases. Similarly, if microflora take control on certain tissues,they can cause infection as well as destruction. Likewise, the Microbe mayabsorb some of the hosts nutrients due to competition, leading to thedevelopment of bacterial antibiotic resistance in humans.
