What is microbial genetics and molecular biology?
Microbiology is the hands-on study of bacteria, viruses, fungi and algae and their many relationships to humans, animals, plants and the environment. Cell and molecular biology bridges the fields of chemistry, biochemistry and biology as it seeks to understand life and cellular processes at the molecular level.
Why is microbial genetics important?
2) Microbes provide relatively simple system for studying genetic phenomenon and thus useful to other higher organisms. Microbial genetics will be useful to study the gene transfer from one organism to another. …
What is microbial life?
“Microbe” is a general term that encompasses almost any microscopic organism, including bacteria and archaea, which lack a cell nucleus or other membrane-bound cellular structures, and protists (mostly unicellular organisms that lack specialized tissues, and hence, are neither plant nor animal nor fungus).
What are the microbial diseases?
Microbes and disease
| Infectious disease | Microbe that causes the disease | Type of microbe |
|---|---|---|
| Whooping cough | Bordatella pertussis | Bacterium |
| Bubonic plague | Yersinia pestis | Bacterium |
| TB (Tuberculosis) | Mycobacterium tuberculosis | Bacterium |
| Malaria | Plasmodium falciparum | Protozoan |
What are the 3 main types of microbes?
The major groups of microorganisms—namely bacteria, archaea, fungi (yeasts and molds), algae, protozoa, and viruses—are summarized below. Links to the more detailed articles on each of the major groups are provided.
What are the 5 types of microbes?
Microbial diversity is truly staggering, yet all these microbes can be grouped into five major types: Viruses, Bacteria, Archaea, Fungi, and Protists.
Is itching a sign of infection?
Itching may be a symptom of an infection, such as: chickenpox or another viral infection. athlete’s foot – a fungal infection that causes itching in between the toes. ringworm – a fungal infection that causes a ring-like red rash to develop on the skin and can cause an itchy scalp.
What is direct contact?
Direct contact includes touching an infected individual, kissing, sexual contact, contact with oral secretions, or contact with body lesions. This type of transmission requires close contact with an infected individual, and will usually occur between members of the same household or close friends and family.
Which disease spread through direct contact?
Many illnesses spread through contact transmission. Examples are chicken pox, common cold, conjunctivitis (Pink Eye), Hepatitis A and B, herpes simplex (cold sores), influenza, measles, mononucleosis, Fifth disease, pertussis, adeno/rhino viruses, Neisseria meningitidis and mycoplasma pneumoniae.
What are examples of direct contact?
Direct contact occurs through skin-to-skin contact, kissing, and sexual intercourse. Direct contact also refers to contact with soil or vegetation harboring infectious organisms. Thus, infectious mononucleosis (“kissing disease”) and gonorrhea are spread from person to person by direct contact.
What are three methods of disease transmission?
Infectious diseases are transmitted from person to person by direct or indirect contact….Indirect contact
- Airborne transmission.
- Contaminated objects.
- Food and drinking water.
- Animal-to-person contact.
- Animal reservoirs.
- Insect bites (vector-borne disease)
What are the common method of transmission of diseases?
Contact transmission is the most common form of transmitting diseases and virus. There are two types of contact transmission: direct and indirect. Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person.
What are the two main principles of infection control?
There are 2 tiers of recommended precautions to prevent the spread of infections in healthcare settings: Standard Precautions and Transmission-Based Precautions. Standard precautions are used for all patient care.
What is the single most effective method of infection control?
Hand hygiene is a major component of standard precautions and one of the most effective methods to prevent transmission of pathogens associated with health care.
What is the first basic element to infection control?
Abstract. A dental health care worker (DHCW) has an obligation to prevent the spread of health care associated infections. Adhering to proper hand hygiene procedures, selecting appropriate hand hygiene products and the use of gloves are all important elements of infection control.
How can microbial infections be prevented?
Microbe Awareness
- Keep immunizations up to date.
- Wash your hands often.
- Prepare and handle food carefully.
- Use antibiotics only for infections caused by bacteria.
- Report to your doctor any rapidly worsening infection or any infection that does not get better after taking a course of antibiotics, if prescribed.
