Benefits the stuff in our pie hole.

Benefits of microflora:

a.      
Preventing colonization by microbial anatgonism competing
with nutrients and space and produce toxic condition or environmental condition
to keep harmful pathogens away (acidity in vagina).

b.     
Develop immune system by keeping it active by providing
antigens. (https://quizlet.com/7646560/normal-flora-flash-cards/)

c.      
Microflora
are essential for us to survive.

d.     
They
gain their food from the stuff in our pie hole.

e.     
If colonies
of bacteria are worn out by poisons or antibiotics, they must be replaced
otherwise we would die ultimately. (https://www.quora.com/What-are-the-benefits-of-normal-flora)

f.       
They provide a host
defence mechanism by taking control on ecological niches for bacteria, e.g. the intestinal villi.

g.      
Bacteria produce
and excrete various compounds like vitamin B12 and vitamin K in the intestine
which are important nutrients for host.

h.     
The oral microflora
assist in immunity through inducing low level of circulating and secretory antibiotics
that kill pathogens. In other words, they enhance body’s immunity.

i.        
The oral bacterial
flora kill nonindigenous species by producing inhibitory fatty acids, peroxides
and bacteriocins (it is a protein and bacreria produce it, it helps in stamping
and killing microbes). (https://www.slideshare.net/amanullah9803150/microbial-floraofthehumanbody)

j.       
Microflora
help to digest food as they break down foodstuffs that are normally
indigestible by the host into forms that are easily digestible by the hosts.

k.      
The Microflora
protects the host from  infection by harmful
pathogenic organisms.

l.        
They produce
antibacterial substances as by product of metabolism, so they have a local
antibiotic effect which retard the attack of invaders on host.

m.   
They
stimulate an immunological response (an antibody-mediated immune response) as
they act as antigens in the human body. (https://www.ukessays.com/essays/biology/normal-flora-and-their-benefits.php)

Disadvantages of microflora:

a.      
Microflora
is harmful when overgrown (i.e. use of antibiotics) and misplaced (i.e. urinary
tract flora may placed with facel flora). (https://quizlet.com/7646560/normal-flora-flash-cards/)

b.     
Microflora may also
cause disease in following conditions:

·        
If individual
become immunocompromised.

·        
If he change his
anatomical location as usual. (https://www.slideshare.net/amanullah9803150/microbial-floraofthehumanbody)

Conclusion

There are few limitations of microflora to the human body as
well. For example, most of the microflora are pathogens and may cause
infectious diseases. Similarly, if microflora take control on certain tissues,
they can cause infection as well as destruction. Likewise, the Microbe may
absorb some of the hosts nutrients due to competition, leading to the
development of bacterial antibiotic resistance in humans. (https://www.ukessays.com/essays/biology/normal-flora-and-their-benefits.php)
