Simply Microbiology (Bacteria, Fungi, Protozoa, Viruses)

Simply Microbiology for dummies

Microbiology is the branch of science that concerned with the micro-organisms.
Micro-organisms- organisms that can’t be seen by human eye, it needs microscope to be seen.
Microbiology is a big tree with branches like Paracytology, Mycology, Bacteriology and Virology.
Simply what is the difference?

Colonies of bacteria under electronic microscope 
 Single cell living organisms that found almost any where on the planet, even environments like hot sulfur springs and deep oceans abyss.
It found in colonies and causes variety of diseases most common sour throat.
Classified to many groups, most popular gram positive group and the gram negative group.
Can be easily killed outside the body by soaps and alcohols by dissolving the external wall of the cells, or internally by antibiotics which attack different organelles (small organs) of the bacterial cells, most popular is the penicillin .
 Penicillin was discovered in 1928 by bacteriologist Alexander Fleming when a piece of infected piece bread infected with  fungi spores dropped by mistake in one of his bacterial colonies, once the fungi grow he secreted this magic material to defend its territory which been identified and isolated and it was truly magic at the time.He named the active agent, penicillin.

Virus structure model
Unicellular live forms which are characterized by its ability to stay dormant outside the body for decades waiting to be introduced to certain species of living creatures, in a certain no (called infection dose) and in a certain stat of the immune system to cause the infection.
Viruses also characterized by their sing chain D.N.A which make them very resistant and very adaptable to new types of therapies.
Usually viruses have now specific treatment but symptomatic treatment is to be supplied untile the body forms the suitable antibodies to kill the viral infection,
Most common, H.I.V, Hepatitis A, B, C, Influenza virus, Bird flue virus, H1N1 virus, Ebola virus.

Is multi-cellular organisms which live on dead organic materials, usually needs a very weak immunity system or peripheral low blood supply place to infect human body.Treatment usually requires a long term therapy.
Most popular are the Onychomycosis of the nails.

They are either unicellular or multicellular organisms which also require a weak immune system or biological property change like (PH dramatic change) to infect human body.
Most common are Entameba Histolytica (bloody stool with pain) and Trichomonas Vaginalis ( pain, itching and awful discharge from vaginal infection).
