MICROSCOPE
Can be defined as the study of microbes

MICROBIAL ENEMIES
It has been estimated that perhaps as many as 500 to 1,000 different species of microbes live on and in us. Collectively these microbes are known as our
INDIGENOUS MICROFLORA or indigenous microbiota
Microbes that colonized or inhabit in our body are known as
OPPORTUNISTIC PATHOGENS
Do not cause disease under ordinary conditions, but have the potential to cause disease should the opportunity present itself
OPPORTUNISTIC PATHOGENS
Mini microbes are involved in the decomposition of dead organisms and the waste products of living organisms, collectively, they are referred to as
DECOMPOSERS OR SAPROPHYTES
Is an organism that lives on dead or decaying organic matter
SAPROPHYTES
Some microbes are capable of decomposing industrial waste. Thus we can use microbes genetically engineered microbes, in some cases to clean up after ourselves. The use of microbes in this manner is called
BIOREMEDIATION
The study of the relationship between microbes and environment is called

Serve as the starting point of many food chains
