What Is Bacteria And Types Of Bacteria
What is Bacteria
The word bacteria is the plural of bacterium. Grammatically the headline should just say “What are bacteria?” The incorrect usage has been included in the headline to remind readers that it is wrong – and hopefully help correct an increasingly common mistake in the English language. Bacteria are tiny living beings (microorganisms) – they are neither plants nor animals – they belong to a group all by themselves. Bacteria are tiny single-cell microorganisms, usually a few micrometers in length that normally exist together in million.Antibiotics are used to control bacterial infections.
Types of Bacteria
Salmonella Typhi bacteria is a gram negative organism that is the causative agent of typhoid fever. It is associated with a high mortality rate after initial infection and characterized by blood diarrhea, vomiting, dehydration, fever and may lead to death if proper treatment is not instituted at the right time.
The most common causative agent of food poisoning throughout the world is Enteritis salmonella bacteria and can lead to serious and life threatening food poisoning, diarrhea, circulatory shock and dehydration in children. Infection can be controlled by timely intake of proper antibiotics and circulatory support.
Vibrio cholerae bacteria is the causative agent of cholera and is associated with intake of improperly cooked food or poor sanitary conditions. Vibrio Cholerae is linked to hundreds and thousands of deaths worldwide (mostly in under- developed countries) due to cholera outbreak.
E- Coli is a gram negative bacillis as discussed previously and is considered as a causative agent of traveler’s diarrhea; however some pathogenic strains can also lead to bloody diarrhea and circulatory shock.
Streptococcus Pyogenes is the causative agent bacteria of mild sore throat and skin infections that may worsen in certain situations to lead to life threatening infections like toxic shock syndrome and septicemia (when bacteria gain access to the blood stream). It is classified as gram positive coccus that grows mainly in chains.
