GENERAL

What are microorganisms and their types?

Microorganisms are the microbes that are microscopic or tinny which can’t be seen with the naked eye. Various microbes are Bacteria, Fungi, Archaea, Protists,etc. Microbes are the cause of various diseases in humans and animals but all microbes are not harmful.Some microbes are useful like their various types that assist us to digest and absorb nutrients. Some bacteria actually produce several nutrients like vitamins and minerals in our body. 

These bacteria actually reside inside of our interstitial track.These microbes actually produce folic acid , niacin, vitamin B6 and B12. The useful bacteria also saves us from harmful bacteria and removes them from our gut. You may be surprised to learn their role in our gut and their useful participation. Types of microorganisms are assisting and strengthening our digestive and immune systems. 

Are all microbes bad?

This is misconception that all the microbes are bad, you may be amazed to learn some the microbes are good for our health.For example Yogurts is types of bacteria, but this bacterial actually assist in the digestion and improve the efficiency of the digestive system.The other friendly microbes actually live in the gut of the human and they are going to assist aus in producing the various kind of mineral and vitamins. In animals like goats and cows the bacteria is assisting them to digest the uncooked food.Same goes for the carnivores, these animals are able to digest the prey by the assistance of the microbes.

There are basically 3 major groups of the microbes:

Viruses:

Viruses are the simplest of all microbes, and their genome is constructed on either DNA or RNA. They are packed inside a protein shell and it is all of the  body structure. The protein shell is also called the capsid, and made of a cell.They are unicellular organisms and this is the main reason we are calling them acellular cells.These animals are not able to make their own protein and require a host cell to reproduce or make protein. You can say virus are not true being as they can’t live independently, but when they are able to find their host, they suddenly become reactive and turn to be a living being.

Prokaryotes:

Bacteria and Archaea are the prokaryotes(“pro”=before, “karyotes”= nucleus). They are single cellular cells and DNA genome floats around the cytoplasm.Many prokaryotes have one or more smaller circles of DNA called plasmids and it carry addition genes. Bacteria and Archaea have similar cells structure. The Prokaryotes have a complete cell structure as compared to the virus and all the parts of the cells are well defined and you can recognize them under microscope.

Eukaryotes

The eukaryotes include the protists, fungi, plants and animals The word “eu” = true, “karyote” = kernel or nucleus in which the linear DNA genome is packed by multiple chromosomes. Eukaryotes  can be plants, animals or they have multiple chromosomes to reproduce and increase their population. You can say that the eukaryotes are more advanced as compared to the Prokaryotes. They are going to reproduce and reorganize with the passage of time, as they are more defined asexual reproduction via mitosis.

Conclusion:

All microbes are not bad for us, you may be surprised to learn their role in our gut and their useful participation in the digestion process. Some microbes are assisting in the digestive and immune system, if you have more friendly microbes than the harmful microbes.Then you have a better immune system due to the friendly microbes and their presence in our body.
