write a short note on common human diseases caused by micro organism.
Answers
Answer:
Different micro organisms cause different type of diseases to human hence being dangerous to human health.
Examples of these common micro organisms are viruses, bacteria, protists and fungi. All these examples cause different diseases like Vibro cholerae which is a micro organism causes cholera to human beings. A bacteria called
Clostridium tetani causes tetanus.
Theses diseases can even lead to death. Though, It can still be controlled in various ways.
These ways are:
- Keep immunizations up to date.
- Wash your hands often.
- Prepare and handle food carefully.
- Use antibiotics only for infections caused by bacteria.

Answer:
The five major groups of microbes
Microbial diversity is truly staggering, yet all these microbes can be grouped into five major types.
Viruses, Bacteria, Archaea, Fungi, and Protists.
Explanation:
■ Viruses :-Viruses are the smallest of all the microbes. Their genome is made of either DNA or RNA (not both), and this is packaged inside a protein shell called a capsid.
■ Bacteria :-Bacterial cells are mostly circular (coccus, plural cocci) or rod-shaped (bacillus, plural bacilli), but a few have spiral or corkscrew shapes. Another defining features is the use of peptidoglycan as a component of their cell walls.
■ Archaea ;-Archaea look similar in size and structure to bacteria but come in a wider variety of cell shapes. Many archaea live in hostile environments, some interact with other organisms, but no archaea are known to cause disease. Unlike bacteria, they do not have peptidoglycan in their cell walls.
■ Fungi :-Fungi exist as either single cells (yeasts) or as multicellular organisms formed of thin, branching tubular structures called hyphae.
■ Protists :-The protists are a very varied group consisting of all the eukaryotes that are not fungi, plants or animals. Most are unicellular and include plant-like algae, animal-like protozoa and fungi-like slime molds.
