Where do most microorganisms live?
Microbes are tiny living things that are found all around us and are too small to be seen by the naked eye.
They live in water, soil, and in the air.
The human body is home to millions of these microbes too, also called microorganisms..
What are the 4 routes of transmission?
Routes of transmissionDirect Contact Transmission. Direct contact transmission occurs through direct body contact with the tissues or fluids of an infected individual. … Fomite Transmission. … Aerosol (Airborne) Transmission. … Oral (Ingestion) Transmission. … Vector-Borne Transmission. … Zoonotic Transmission.
How are microorganisms spread?
Transmission of microorganisms occurs directly from one person to another by one or more of the following means: droplet contact by coughing or sneezing on another person. direct physical contact by touching an infected person. direct physical contact (usually by touching soil contamination or a contaminated surface)
Where is the most bacteria found in a house?
While many people assume that the bathroom doorknob would be the dirtiest, the NSF found other spots that ranked higher with bacteria, including:bathroom light switches.refrigerator handles.stove knobs.microwave handles.
What are the microorganisms that cause disease?
A variety of microorganisms can cause disease. Pathogenic organisms are of five main types: viruses, bacteria, fungi, protozoa, and worms. Some common pathogens in each group are listed in the column on the right.
What are the methods of disease transmission?
Modes of transmissionDirect. Direct contact. Droplet spread.Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
Where can you find micro organisms that cause disease?
Microbes can enter the body through the four sites listed below: Respiratory tract (mouth and nose) e.g. influenza virus which causes the flu. Gastrointestinal tract (mouth oral cavity) e.g. Vibrio cholerae which causes cholera. Urogenital tract e.g. Escherichia coli which causes cystitis.
What are the harmful microorganisms?
These microbes are called pathogens. They are specially adapted to infect and multiply within a host. Some diseases caused by pathogens are polio, cholera, mumps, rabies, malaria etc. Some microorganisms need a carrier to transmit diseases.
What are examples of microorganisms?
1.2A Types of MicroorganismsBacteria.Archaea.Fungi.Protozoa.Algae.Viruses.Multicellular Animal Parasites.
What are the 5 branches of microbiology?
Pure microbiologyBacteriology: the study of bacteria.Mycology: the study of fungi.Protozoology: the study of protozoa.Phycology/algology: the study of algae.Parasitology: the study of parasites.Immunology: the study of the immune system.Virology: the study of viruses.Nematology: the study of nematodes.More items…
What are the 7 major types of microorganisms?
The major groups of microorganisms—namely bacteria, archaea, fungi (yeasts and molds), algae, protozoa, and viruses—are summarized below.
What are 5 helpful microorganisms?
Useful Microorganisms include: Saccharomyces cerevisiae, Aspergillus oryzae, L. plantarum, Thiobacillus ferrooxidans and Corynebacteria.
What are the conditions needed for microorganisms to grow?
In order to grow successfully, microorganisms must have a supply of water as well as numerous other substances including mineral elements, growth factors, and gas, such as oxygen. Virtually all chemical substances in microorganisms contain carbon in some form, whether they be proteins, fats, carbohydrates, or lipids.
How do pathogenic microorganisms grow and spread?
Pathogens can be transmitted a few ways depending on the type. They can be spread through skin contact, bodily fluids, airborne particles, contact with feces, and touching a surface touched by an infected person.
What are the useful microorganisms?
Following are a few useful microorganisms:Bacteria.Fungi.Protozoa.
What can you do to prevent this disease from happening?
Decrease your risk of infecting yourself or others:Wash your hands often. … Get vaccinated. … Use antibiotics sensibly. … Stay at home if you have signs and symptoms of an infection. … Be smart about food preparation. … Disinfect the ‘hot zones’ in your residence. … Practice safer sex. … Don’t share personal items.More items…
What diseases are carried in body fluids?
Examples of diseases spread through blood or other body fluids:hepatitis B – blood, saliva, semen and vaginal fluids.hepatitis C – blood.human immunodeficiency virus (HIV) infection – blood, semen and vaginal fluids, breastmilk.cytomegalovirus (CMV) infection – saliva, semen and vaginal fluids, urine, etc.More items…
What are the main routes infection can enter the body?
The Main Routes Infection can Enter the Body are: Through saliva (e.g. glandular fever). Through contaminated substances entering the bloodstream e.g. tetanus can be contracted through wounds when handling contaminated soil. Through the air – e.g. tuberculosis.
