diseases caused by bacteria
Hello. Welcome to solsarin. This post is about “diseases caused by bacteria”.
What are 5 diseases caused by bacteria?
Other serious bacterial diseases include cholera, diphtheria, bacterial meningitis, tetanus, Lyme disease, gonorrhea, and syphilis.
What type of diseases are caused by bacteria?
Bacteria cause many common infections such as pneumonia, wound infections, bloodstream infections (sepsis) and sexually transmitted diseases like gonorrhea, and have also been responsible for several major disease epidemics.
What are 4 types of bacteria?
There are four common forms of bacteria-coccus,bacillus,spirillum and vibrio.
Coccus form:- These are spherical bacteria. …
Is TB a bacterial disease?
Tuberculosis is a bacterial disease caused by Mycobacterium tuberculosis. TB usually affects the lungs but it can also affect other parts of the body such as the brain, lymph nodes, kidneys, bones, joints, larynx, intestines or eyes.
What are the 5 types of bacteria?
Bacteria are classified into five groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or 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.
Which disease is bacterial in origin?
Examples of bacteria-caused infections include pneumonia, plague, typhoid. Although some diseases have been eradicated, the emergence of new infections, such as MRSA, provides evidence that evolution is an ongoing process. Epidemiologists study how disease affects a population.
What are 5 characteristics of bacteria?
Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.
Can you get TB from kissing?
You cannot get TB germs from:
Saliva shared from kissing. TB is NOT spread through shaking someone’s hand, sharing food, touching bed linens or toilet seats, or sharing toothbrushes.
What are the 3 types of tuberculosis?
Tuberculosis is a bacterial infection that usually infects the lungs. It may also affect the kidneys, spine, and brain. There are 3 stages of TB—exposure, latent, and active disease.
Is a virus a bacteria?
Viruses are not living organisms, bacteria are.
Viruses only grow and reproduce inside of the host cells they infect. When found outside of these living cells, viruses are dormant.
What is the Difference between Viruses and Bacteria?
Living or Not
Viruses are not living organisms, bacteria are.
Viruses only grow and reproduce inside of the host cells they infect. When found outside of these living cells, viruses are dormant. Their “life” therefore requires the hijacking of the biochemical activities of a living cell.
Bacteria, on the other hand, are living organisms
that consist of single cell that can generate energy, make its own food, move, and reproduce (typically by binary fission).
This allows bacteria to live in many places—soil, water, plants, and the human body—and serve many purposes.
They serve many vital roles in nature by decomposing organic matter
(maybe not that vital to anyone who’s forgotten leftovers in the back of the fridge)
and by converting nitrogen, through nitrogen fixation, to chemicals usable by plants. Bacteria even know how to work as a team through something called quorum sensing.

Size
Bacteria are giants when compared to viruses. The smallest bacteria are about 0.4 micron (one millionth of a meter) in diameter while viruses range in size from 0.02 to 0.25 micron. This makes most viruses submicroscopic, unable to be seen in an ordinary light microscope. They are typically studied with an electron microscope.
Mode of Infection
Their mode of infection is different. Because of their distinct biochemistry, it should come as no surprise
that bacteria and viruses differ in how they cause infection.
Viruses infect a host cell and then multiply by the thousands, leaving the host cell and infecting other cells of the body.
A viral infection will therefore be systemic, spreading throughout the body.
Systemic diseases caused by viral infection include influenza, measles, polio, AIDS, and COVID-19. Pathogenic bacteria have a more varied operation and will often infect when the right opportunity arises, so called opportunistic infection.
Examples of bacterial disease include pneumonia, tuberculosis, tetanus, and food poisoning.
How Viruses Interact with Bacteria
Viruses can infect bacteria. Bacteria are not immune to viral hijackers which are known as bacteriophages—viruses that infect bacteria. We don’t want to judge, but this may be one more reason to put viruses one notch higher in the nasty germs hierarchy.

What are the 4 types of diseases?
There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic diseases and non-genetic hereditary diseases), and physiological diseases. Diseases can also be classified in other ways, such as communicable versus non-communicable diseases.
What is a simple definition of bacteria?
Where are bacteria found?
Is polio a bacterial disease?
Polio is a viral disease which may affect the spinal cord causing muscle weakness and paralysis. The polio virus enters the body through the mouth, usually from hands contaminated with the stool of an infected person.
What are the six killer diseases?
Of great importance to public and child health are the vaccines against the so-called six killer diseases of childhood-measles, pertussis, diphtheria, tetanus, tuberculosis and poliomyelitis.
Is diphtheria a bacterial disease?
It is the toxin that can cause people to get very sick. Diphtheria bacteria spread from person to person, usually through respiratory droplets, like from coughing or sneezing.
What is communicable disease?
Communicable diseases, also known as infectious diseases or transmissible diseases, are illnesses that result from the infection, presence and growth of pathogenic (capable of causing disease) biologic agents in an individual human or other animal host.
Is Ebola a virus?
Ebola virus disease (EVD) is a deadly disease with occasional outbreaks that occur mostly on the African continent. EVD most commonly affects people and nonhuman primates (such as monkeys, gorillas, and chimpanzees).
What is the most infectious disease?
Bubonic and Pneumonic Plagues.
Is E. coli bacteria harmful?
Most E. coli are harmless and actually are an important part of a healthy human intestinal tract. However, some E. coli are pathogenic, meaning they can cause illness, either diarrhea or illness outside of the intestinal tract.
Is E coli a bacillus?
Escherichia organisms are gram-negative bacilli that exist singly or in pairs. E coli is facultatively anaerobic with a type of metabolism that is both fermentative and respiratory. They are either nonmotile or motile by peritrichous flagella. E coli is a major facultative inhabitant of the large intestine.
What is the difference between a viral disease and a bacterial disease?
Answer From Pritish K. Tosh, M.D. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren’t effective against viruses.
What do humans and bacteria have in common?
This means that the same codon “means” the same amino acid in all organisms. For example, in both humans and bacteria, a codon made of three thymine DNA-letters will code for an amino acid called Phenylalanine. … This code is common to both humans and bacteria, and indeed, for most living things.
Can I marry a girl with TB?
For example, if, due to TB and its lengthy treatment, a woman’s marriage to her cousin does not go ahead, then it is not her last opportunity to marry if she has many other as yet unmarried cousins to marry once she is in good health again.
