Types of Micro-Organisms that Cause Disease Essay Case Study
please “briefly” describe each point!
Describe 3 types of micro-organisms that can cause disease.
Three types of microorganism include bacteria, viruses and fungi. Let’s briefly explain each of them. Types of Micro-Organisms that Cause Disease Essay Case Study
Bacteria are single-celled, prokaryotic organisms that can be found virtually anywhere, from soil to water to living organisms. They can cause a wide range of diseases, such as tuberculosis, pneumonia, and strep throat. Bacteria can infect different systems of the body, including the respiratory, urinary, and digestive systems. They can be transmitted through direct contact, such as touching or kissing, or indirect contact, such as through contaminated food or water.
Example of bacteria and diseases caused by them are :
1. Streptococcus pyogenes: causes strep throat, impetigo, and necrotizing fasciitis (flesh-eating disease).
2. Escherichia coli (E. coli): causes food poisoning, urinary tract infections, and sometimes severe infections such as sepsis.
3. Mycobacterium tuberculosis: causes tuberculosis, a respiratory disease that can spread to other organs of the body.
Description of viruses, diseases caused and examples.
Viruses are infectious agents that are smaller than bacteria and cannot reproduce on their own. They can infect a variety of living organisms, including plants, animals, and humans. Some common viral diseases include the flu, HIV/AIDS, and COVID-19. Viruses can infect different systems of the body, such as the respiratory or digestive systems, and can be transmitted through various routes, such as through the air, through bodily fluids, or through contaminated objects.
1. Influenza virus: causes the flu, a respiratory illness that can range from mild to severe.
2. Human immunodeficiency virus (HIV): causes acquired immunodeficiency syndrome (AIDS), a disease that attacks the immune system and can lead to various infections and cancers.
3. SARS-CoV-2: causes COVID-19, a respiratory illness that has become a global pandemic since its outbreak in 2019.
Description of fungi, disease caused and examples.
Fungi are eukaryotic organisms that include yeasts, molds, and mushrooms. Some fungi can cause disease in humans, such as ringworm, athlete’s foot, and candidiasis. Fungi can infect different systems of the body, including the skin, lungs, and nails. They can be transmitted through direct contact with an infected person or animal, or through indirect contact with contaminated objects or surfaces. Fungi thrive in warm and moist environments, such as in soil, on plants, or on the human body.
1. Candida albicans: causes candidiasis, a common fungal infection that can affect the skin, mouth, throat, and genital area.
2. Trichophyton species: causes ringworm, a skin infection that can appear as a circular rash with scaly edges.
3. Aspergillus species: can cause a range of illnesses, including aspergillosis, which is a lung infection that can be serious in people with weakened immune systems.
In conclusion, disease-causing organisms such as bacteria, viruses, and fungi can cause a range of illnesses and infections, and it is important to understand their characteristics and how they can be prevented and treated. Types of Micro-Organisms that Cause Disease Essay Case Study
