Diseases Caused by Microorganisms Can be Prevented
Published by A vector is an organism that transmits pathogens from one person to another. Vector control is very effective in controlling the spread of diseases such as malaria and cholera as it is used to reduce the number of vectors by killing or preventing the reproduction of vectors. The life cycles and habits of vectors are two important aspects in the control of vectors..
Microorganisms also known as microbes are minute organisms that cannot be seen with the naked eye. They can only be seen with the help of microscope. Microorganisms are classified into 5 groups: a) Bacteria. b) Viruses. c) Protozoa. d) Algae. e) Fungi.

Certain microbes such as fungi and bacteria are beneficial while others such as viruses are harmful. Microorganisms are grouped based on the following criteria: a) Size. b) Shape. c) Method of reproduction. d) Nutrition. e) Habitat.
Infection of diseases caused by microorganisms can be prevented by: a) the control of vectors. b) Sterilization. c) Immunization.
Control of Vectors
A vector is an organism that transmits pathogens from one person to another. Vector control is very effective in controlling the spread of diseases such as malaria and cholera as it is used to reduce the number of vectors by killing or preventing the reproduction of vectors. The life cycles and habits of vectors are two important aspects in the control of vectors. Two main examples of vectors are mosquitoes and houseflies.

a) Control of mosquitoes
The life cycle of a mosquito shows a complete metamorphosis that goes through that goes through four stages: egg, larva, pupa and the adult (imago). Female mosquitoes lay eggs on the water surface of stagnant water found in drains, ponds or in containers such as empty tins and tires.

After 2-3 days, the eggs hatch into larvae which hang from the surface of the water. Larvae feed on microorganisms in the water. Larvae change into pupae after 14 days. Pupae do not feed. Pupae undergo metamorphosis and change into adult mosquitoes. Mosquitoes can be controlled at each stage of their life cycle.

Very informative…the pictures were amazing, but kinda grossed me out. I wish I could have read this without looking at them. Lol I am a typical girl !

Great Science lesson.

yuuk,Those are disgusting little critters.It’s a good thing we don’t go around our houses with a magnifying glass. We would be horrified. Great information.

This is indeed a very great problem that is needed to be addressed in Developing countries. According to an estimation about 300,000 people are affected by malaria alone allover the world. Your article is very helpful for those ignorant of the destructive effect of these tiny micro-organisms can have on one. thank you. I sure learned something new today.

this is very important topic. everyone should know this to prevent diseases…

Great info, as always. If you could, go back to your New Immunization programmed in Malaysia list and change the second Hep B to say second and not first a second time.

Unfortunately, the solutions used to suspend these vaccinations have been proven to be deadly. Many people have gotten ill or died from accepting these shots, not because the theory is wrong, or because the anitbodies aren’t created, but because the carrier solution contains mercury or other toxic chemicals. The recent H!N1 vaccine is a prime example.

great amount of detail – a real “microscope” of an article
