The Existence Of Bacterium In Universe


Powered by FeedBurner

Dear readers,

Yesterday I was writing about the existence of Virus in the universe, so today I write about the bacteria. I write this article because after I tried to search what virus was and then again I interested to know better what bacteria is. To understand this creature. I was blind before, but now I realize there are so many things in life that we can not see with naked eyes that they are exist and also part of us. Realize or not, these small creatures give big impact into our life. 

" Bacteria/Schizomyceta is a single-celled plant which can divide itself into 2 parts " 


Unique Characteristic Facts of  Bacteria

  • Most of bacteria do not harm humans, only few are harmful. The harmful bacteria that can cause disease referred to pathogenic bacteria or germs. the friendly bacteria help humans in destroying the food so would be easy for other body organs to digest and absorb the food in intestine.
  • Bacteria is colonized creatures. 
  • Bacteria live in the air, soil and water.
  • Bacteria which colonized in human body breeds prolifically in moist and warm condition
  • Most bacteria require oxygen and are called by aerobic bacteria. They grow near the skin surface and respiratory tract.
  • Bacteria that do not need oxygen are called by anaerobic bacteria. They grow in tissue, deep wounds, and colon.
  • Most bacteria do not move. Bacteria that can't move usually spread with the flow of blood, body fluid or air flow.
  • The few that can move, they are very agile and can swim using its whip.
  • Bacteria's reproducing system by dividing every each itself  in every 20 minutes.
  • When bacteria in state of danger, some of bacteria can be able to form themselves as like a strong bag to take cover themselves. The bag form called as spore.
  • The aerobic bacteria that can be able to form spore called as bacillus. The placement of spore in bacillus is static, such as : in the middle of the body which called central spore; located at the end of the body which called terminal; located between central and terminal which called as sub-terminal.
  • The anaerobic bacteria that can form spore called as clostridium.
  • The shape of spore can be like a ball or shaped like a bar.
  • People familiar with bacteria since the 17th century once the invention of  microscope. However, the understanding of pathogenic bacteria acquired in the mid of 19th century by Louis Pasteur.
  • Based on shape, Ferdinand Cohn ( 1872 ) divided bacteria into 3 categories : shape as like round ball which called as coccaceae/coccus; shape as like bar which called bacteriaceae/bacillus; shape as like spiral which called spiriltaceae.
  • In coccus there are differences in the shape too and it is divided by 3 shapes. Regular coccus which has shape just like a round ball shape, such is in diplococcus pneumoniae which almost alike triangle shape, and in gonococcus which almost alike a coffee seed shape. 
  • In coccus, it is categorized based on they way the gather; coccus which always clustered two called by diplococcus, coccus which always clustered four called by tetracoccus ( Gaffkya ), coccus which always clustered eight ( shape as like cube ) called by sarcina, coccus in a row as chain called by streptococcus, coccus in a row as like grape called by staphylococcus.
  • In bacillus most shape are alike round in the end such as in bacillus anthrax ( which caused anthrax ), and also shape alike sharp-tipped such in bacillus fusiformis. 
  • In bacillus, also it is categorized based on the way it clustered, but only divided by 2 type ; bacillus which always clustered two which called by diplobacillus, and clustered like a line called by streptobacillus.
  • In spiral were divided by the length and the wave of spiral. Some spiral has long shape which has 1 or 2 wave & if short the shape almost a like a curved rod-shape, i think is like a coma (,) which called vibrio

Substances Contained in Bacteria's Body
Material which contained in bacteria are water, albumen ( albumen, globulin, nucleo-olbumin ), carbohydrate 
( polysaccharid ), fat, lifoid, and salt which contained Na, Ca, P, S, Cl etc. The shape of bacteria can be change depends on how much protein in a media where the bacteria live and grow.

The Body Structure of  Bacteria
  • Granula;this is a part based for bacteria for saving the food for bacteria itself which contained substances mentioned above. This granule shaped such as dots (.) which called by volutin.
  • Core / Cell Nucleus; we know already that bacteria is a cell, and we do know in a cell there is always a main core. In bacteria we can find stately the core but some of bacteria the core mixed with protoplasm around the bacteria body.
  • Cytoplasm membrane ( Ectoplasm  & endoplasm ) ; in bacteria body there is ectoplasm which surrounding the endoplasmic. In streptococcus and streptobacillus, the ectoplasm is solid and connected, but the endoplasm is not homogenous and can be easily filled with substances which the origin is not clear. Cytoplasm membrane; in some bacteria, it has cytoplasm which shaped like a sheath and as like mucus.
  • Hair Whip: For some bacteria that can be able to move; in its body structure showed that bacteria has hair as like a whip to move which made from from protoplasm which called ectoplast. These are the classification of bacteria with whip in its body or at the end in its body :
  1. bacteria which has only 1 whip at end of its body; called by monotricha
  2. bacteria which has two whip in its body, called by amphitricha
  3. bacteria which has many whips in its body, called by lophotricha
  4. bacteria which has so many whip hair around its body, called by peritricha
  5. bacteria with no whip hair, called by atricha
