What are the 5 types of bacteria?

Bacteria are classified into five groups according to their basic shapes:

  1. spherical (cocci),
  2. rod (bacilli),
  3. spiral (spirilla),
  4. comma (vibrios) or
  5. corkscrew (spirochaetes).

They can exist as single cells, in pairs, chains or clusters. Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow.

What is a simple definition of bacteria?

Bacteria is defined as all organisms that lack a nucleus or other membrane-bound organelles within their cells and includes some that generate energy through photosynthesis (that is called prokaryotic cell).

Where do bacteria live?

Bacteria can survive in almost any environment. Some of the most common habitats include soil, water, humans and animals, mineral surfaces, thermal vents in the ocean floor to name a few.

Where do bacteria come from?

Bacteria are always replicating so they form many generations in their lifetime. Bacteria can come from simple cell division between two bacteria cells or they can come from a single parent cell that reproduces asexually through binary fission.

What are 5 examples of bacteria?

1. E. coli

2. Staphylococcus aureus

3. Salmonella

4. Trichinella spiralis

5. Chlamydia trachomatis

What are 5 characteristics of bacteria?

1) Can be living (viable) and non-living (non-viable);

2) Are prokaryotic;

3) Require oxygen for their metabolism;

4) Reproduce by binary fission;

5) Have genetic material in the form of DNA.

What diseases are caused by bacteria?

In human medicine, bacterial diseases would include tuberculosis, diphtheria, syphilis and leprosy. In animals, the most common disease-causing bacteria are salmonella which causes food poisoning in humans and other animals as well as mastitis in dairy cows.  

Other animal diseases that result from bacteria include anthrax and brucellosis.  Bacterial infections can also be a major contributor to vaginal yeast infections, skin rashes and acne.

What are the 3 main types of bacteria?

Archaea: These do not produce oxygen but they have been found to live in extreme environments such as deep sea vents or hot springs where life is inhospitable to most organisms.

Eukaryotes: These are large, complex cells that contain membrane-bound organelles within their cytoplasm and have genetic material organized into chromosomes.  Examples include fungi, algae and protists (such as yeast).

Virus: These are much smaller than either prokaryotic or eukaryotic cells consisting only of nucleic acid surrounded by a protein coat called a capsid.

Are bacteria alive?

Bacteria are considered the simplest form of life because they lack membrane-bound organelles such as mitochondria or chloroplasts found in other unicellular organisms like protists and plant cells.  They also lack true nuclei which has its DNA condensed into chromosomes.

Is a virus an organism?

Viruses are not considered living because they do not have cells or reproduce on their own.  Instead, they must enter the host cells of other organisms and make use of cellular processes to produce more viral particles.  They can only replicate with the help of a host cell.  Once all host cells in the vicinity of the virus die, so does the virus itself.

Where is the most bacteria found in our bodies?

The gastrointestinal tract is home to approximately 1-2kg (or 2-4 pounds) worth of bacteria at any given time! This intestine-dwelling microbiome consists mostly of aerobic and anaerobic bacteria – microbes that require oxygen and those which do not.

How do bacteria make us sick?

Bacterial infections in the body depends on how well your immune system is able to keep infectious bacterial cells at bay.  However, if your immune system becomes compromised in some way (like when you are fighting off another infection) then it may not be strong enough to fight off a bacterial infection – leading to serious illness or worse.

Where do most of our bacteria reside?

intestinal bacteria

Most of the bacteria that live on and within a human body live in the gastrointestinal tract – about 1-2kg of these tiny organisms!  The rest can be found throughout our skin, hair, nasal passages and other locations that provide an ideal environment for their growth.

How many types of gut flora and bacteria are there and what do they do?

There are at least 1,000 different types of gut flora and bacteria that we know of.  Each one is adapted to a specific environment in the intestinal tract – some prefer the acidity of the stomach while others favor the lower pH found in the intestines.  

The gastrointestinal microbiome helps us digest our food so it can be used for energy production as well as synthesize certain vitamins such as vitamin K and biotin.

How many types of microorganisms live on/in humans?

This number varies from person to person but we all have approximately 100 trillion bacterial cells and 10 quadrillion viruses living within us at any given time! Most of these organisms take up residence across the vast expanse of mucus membranes that line our intestinal tract as well as the other areas mentioned above.

What happens if bacteria overgrow in your body?

Small imbalances in populations of gut flora and bacteria can cause problems such as yeast infections or chronic digestive issues, but major disruptions to the bacterial population is not a good thing either!  

This can cause a condition known as dysbiosis – a state where the balance of your intestinal microflora is disrupted by an overabundance of pathogenic organisms leading to disease.

What about the virus - Are all viruses bad for you?

Not all viruses are bad for you – some actually help out with certain bodily processes.  

For example, there exists a group of RNA viruses called retroviruses which carry out an enzyme called reverse transcriptase that helps with the transcription of DNA!  As you will learn in our article on RNA, transcription is an important part of protein synthesis.

What causes disease? How do we get sick?

Disease occurs when there is a loss of balance between the organisms and environment surrounding us (or more simply put: when bad things happen to good people).  

When your body's immune system loses track of harmful viruses and bacteria living within it, they can start to replicate until they reach dangerous levels or invade other areas where they don't belong such as our blood, brain or heart tissue.  If this happens then serious illness may result, like pneumonia or meningitis

What are the benefits of gut bacteria?

Scientists have begun to study ways that these organisms can improve our health and wellness by producing certain vitamins like vitamin K, biotin and folate (vitamin B9).  K and Biotin deficiencies are known causes of heart arrhythmias while folate is an important nutrient for pregnant mothers to ensure proper fetal development.  

How does healthy gut flora make you more resistant to illness/disease?

The intestinal microbiota helps us digest food so it can be used as energy or synthesized into vital nutrients such as vitamin K.  

A beneficial bacterial population in the intestines may also help prevent harmful pathogenic microorganisms from taking root there.  

Additional research on how these microorganisms interact with our immune system may yield important breakthroughs in how we prevent and treat various illnesses.

What kind of bacteria lives in our mouths?

The number of different bacteria that inhabit our mouths is actually quite small compared to the rest of our bodies.  However, it's estimated that there are around 700-800 bacterial species in the average human mouth! Some of these organisms are beneficial while others are pathogenic, causing diseases like gingivitis or periodontal disease if they begin to multiply out of control.

Which bacteria lives in the esophagus?

Most of the organisms living in the esophagus are actually "aerobic" bacteria, meaning they need oxygen to survive.  These organisms usually don't cause any problems but some strains have been known to cause serious conditions such as Esophageal cancer

What bacteria lines the stomach?

The stomach not only needs to protect itself against harmful organisms that might find their way into the digestive system, it must also help break down food for our body's cells to use as energy.  

It does this by secreting hydrochloric acid which kills most microorganisms and partially digests food - breaking apart proteins into smaller peptides and carbohydrates into simple sugars.  

It's a very harsh environment in the stomach but a healthy amount of "good" bacteria in the intestines helps protect us against dangerous pathogens like cholera, typhoid and salmonella which can be found throughout the world.

What type of bacteria lines the small intestines?

The small intestine is a long, winding tube that absorbs vital nutrients from food and water and helps to eliminate waste.  

This area of the digestive system houses both aerobic bacteria as well as defensive immune cells that help protect it against harmful invaders.

Examples of aerobic bacteria in your small intestines are:

E. coli - important for nutrient production

Lactobacillus acidophilus  - Probiotics, helps digest lactose in milk

Bifidobacterium bifidum  - also a probiotic that helps break down certain complex sugars

Saccharomyces boulardii - Symbiotic yeast that is known for its ability to inhibit pathogenic organisms

What kind of bacteria lives in the large intestines?

The majority of organisms living in our colons fall under the category of "anaerobic bacteria" which means they don't require oxygen to survive.  

These microorganisms help us digest food and extract vitamins like vitamin K and biotin from our diet. They also aid in breaking down carbohydrates into simple sugars that can be used by the body for energy.

Examples of anaerobic bacteria in the large intestines are:

Bacteroides fragilis  - Necessary for proper protein digestion.  Its byproducts help to stimulate immune system cells that protect us against harmful pathogens.

Fusobacterium nucleatum  - Prevents growth of potentially dangerous anaerobic organisms like Clostridia, which can cause gas gangrene and food poisoning

Clostridium butyricum  - Helps aid in the production of vitamins like biotin and thiamine

Lactobacillus plantarum  - A common probiotic that synthesizes enzymes to soften stools and release beneficial nutrients from your meals.

There are also many other organisms that live in your intestines like archaea (which get their energy through methane production), protists, fungi and viruses.

How do you maintain a healthy gut flora?

Diet, postbiotic supplements, and routine health checks are a great way to maintain a healthy gut flora.

Postbiotics: These metabolites help your gut flora in many ways.  They help keep your intestinal lining strong and they stimulate the production of beneficial bacteria.  Everyone's gut flora is a bit different so try a few postbiotics to see what works best for you.

Diet: Fiber helps feed beneficial microbes that line your intestines while sugars found in processed foods provide food for pathogenic microorganisms.

 The best way to keep your gut flora in balance is to eat a nutritious, well-rounded diet that includes plenty of fresh fruits and vegetables.

Health Checks: Once you begin to establish a healthy gut flora they should continue to flourish if their environment remains optimal.  

However, you should still get routine health screenings since problems can occur.  

For example, certain bacteria like C-difficile are becoming more and more present in our society and cause severe intestinal infections which can be deadly if not treated properly.
