The worldwide issue of deadly and infectious illnesses caused by bacteria are becoming one of the biggest medical and scientific issues of the moment.
What is a bacteria?
It is a micro-organism that is unicellular and that is classified as a domain eukarya in the Monera kingdom. In the microscope Bacteria have cell walls, but not nucleus or organelles.
There are various kinds of bacteria (good and bad) however, we will look at a list of frightening infections which are the result of harmful bacteria in this article.
History of Bacterial Diseases
There are numerous examples of evidence found in the form of sculptures and books that portrayed these bacterial infections from the early Egyptian and even ancient Chinese the time (3000 BCE) for hundreds of years. Although we live in a modern age with advancements in biotechnology and medicine, the most common causes of death around the world continue to be bacterial infection. Find out more about the history here.
The following diseases are considered to be the most serious list of bacterial diseases that even the most powerful antibiotics available today aren’t able to kill.
Rare Bacterial Infection On News: In May 2017 the Aquarium located in Vancouver, BC had a strange incident in which a young girl was dragged due to a sea-lion. the video was viewed by millions via social networks. According to Aquarium officials the girl may have contracted a rare bacterial infection known as “Seal finger.” A particular type of bacteria known as Mycoplasma bacteria is found in mouths of sea mammals. The Aquarium accident, girl contracted the bacteria through the bite of a sea lion. If this infection is left untreated the person who contracted it might lose fingers, and possibly the limbs.
Top 14 Infectious and Deadliest Bacterial Diseases
Here are some of the different types of bacterial illnesses which are caused by several causative factors found in all over the globe of bacteria.
- The agent responsible for the disease Bacillus anthracis.
- The first bacterial illness on this list is anthrax. It’s the most severe form of infection that is due to the rod-shaped Gram-positive bacteria Bacillus anthracis (refer to all forms of bacteria in this list). Anthrax is a three-pronged disease such as pneumonia or lung anthrax skin anthrax, intestinal anthrax. Any of these conditions if not addressed immediately could lead in death.
- In the majority of cases the anthrax bacterium exists in spores, and is located in soil. If it is left in this form the bacteria can survive for a long time and develop resistance to radiation and heat.
- The bacterium is frequently utilized in bioterrorism. The terrorists release the spores from the bacterium in crowds and public areas, or mail letters with spores.
- The causative factor of this disease is Clostridium tetani.
- The second bacterial disease is known as lockjaw. It is a fatal bacterial illness which affects the brain and nerve system. This is due to the bacteria Clostridium tetani which creates an toxin that causes muscle paralysis.
- The infection may cause breathing difficulties and spasms due to the toxin affecting the nerves that are involved in the movement.
- Common causes of the bacteria are saliva that is contaminated or the fecal matter, surgical procedures, insect and animal bites.
- The causative agent for this disease is Leptospira sp.
- Leptospirosis is a bacterial disease that is contracted when the nose, eyes or the open area of a wound are exposed to water or soil that has been contaminated with bacteria. The bacteria is typically found in urine of animals.
- If left untreated If it is not treated, the infection can cause damage to the liver, kidneys or lungs. It can also affect the brain. In worst cases, it may cause death.
- Tuberculosis (TB) is an infectious disease that affects the lung. It is usually caused by a bacterium called Mycobacterium tuberculosis.
- Tuberculosis can be fatal if not appropriate treatment.
- The disease spreads by air when the person who is infected coughs, sneezes or even speaks.
- In a variety of developed nations, TB has increased with the increase in HIV infections because of the weakening of the immune systems of people with HIV.
- Antibiotics are employed in treating tuberculosis. It is important to isolate the spread of active infections is also common in the treatment of this disease. The treatment may be lengthy that lasts from six months to one year, according to what the extent of disease.
- Pneumonia is an infection of the lungs.
- Signs of a high-fever include as well as coughing and trouble breathing.
- Although a variety of species of bacteria may cause pneumonia the most prevalent reason most often is Streptococcus pneumoniae. S. pneumoniae is found primarily inside the respiratory tract but don’t typically cause illness in healthy people. In rare cases, the bacteria may become pathogenic and can cause pneumonia.
- The condition usually begins when the bacteria inhale and multiply quickly within the lung.
- S. pneumoniae is also known to cause meningitis and sinus infections. If necessary, the majority of pneumonia will have a high chance of being curable with antibiotic treatment.
- A vaccine against pneumococcal infections can to protect those most likely to develop this disease. Streptococcus pneumoniae are cocci-shaped bacteria that are cocci-shaped.
- Cholera can be described as an intestinal disease that is caused by the bacteria Vibrio cholerae.
- Cholera is a disease that can be contracted through food usually spread through food as well as water that has been contaminated with Vibrio cholerae.
- In the world, around 3 – 5 million infections each year with around 100,000+ deaths.
- Most cases of infection happen in areas that have low sanitation for food and water.
- Cholera may range from moderate to serious. The symptoms of severe forms are vomiting, diarrhea and cramps.
- Cholera is usually treated by hydrating the person. In cases of more serious ailment it is possible to use antibiotics to aid in the recovery of the patient.
- The agent responsible for the disease is Clostridium botulinum.
- Botulism is an uncommon, but extremely fatal bacterial infection caused by the bacteria Clostridium botulinum. The bacterium is responsible for the production of botulinum as which is a neurotoxin lethal that paralyzes a variety of muscles.
- Botulism can be found in a variety of forms such as food-borne or wound, infant and respiratory. Food-borne botulism is most frequent and most fatal.
- It is interesting to note that the agent responsible for this infection is the same bacterium employed to make Botox, the “anti-ageing” botox. Botox.
8. Pseudomonas Infection
- The causative agent is Pseudomonas Aeruginosa.
- It is caused by the common pathogen bacterium Pseudomonas Aeruginosa, pseudomonas infection affects your respiratory tract. In this case, the bacterium harms the lungs and aggravates the symptoms of patients with cystic fibrosis.
- The bacterium is everywhere and is able to infect people in various ways. It is spread by making use of surgical instruments that are contaminated or food items, and may be become spread through food items or through physical contact.
9. MRSA Infection
- The Causative agent is Methicillin-resistant Staphylococcus aureus.
- The bacteria Staphylococcus aureus can be described as a bacterium that naturally occurs found inside our nasal passages. However, a different strain of that bacterium, known as the MRSA or Methicillin-resistant Staphylococcus aureus (biofilm), has evolved to become insensitive to the antibiotic methicillin. Since the bacterium is resistant to the strongest antibiotics it is referred to by some as the “superbug”.
- The disease resulted by this bacteria may be fatal and difficult to cure. The bacterium may cause a bacterial infection of the lungs, the urinary tract as well as the bloodstream.
10. E.Coli Infection
- The agent responsible for the disesase is Escherichia Coli.
- The name implies that E.coli disease can be caused due to the fecal coliform bacteria E.coli. The symptoms of this infection can be similar to that of diarrhea which is often accompanied by a high fever.
- The intensity of diarrhea in this illness can range from bloody to watery.
- If left untreated, bacteria can cause harm to other organs, including the kidney. The result could be permanent disability or even death.
- The causative agents are Neisseria meningitidis Listeria monocytogenes, Streptococcus pneumoniae, E.coli.
- Meningitis is one of the types of bacteria-related disease that affects the brain as well as the spinal cord. In the course of the disease the bacterium can cause meninges swelling (protective membranes) around the organs.
- The bacterium is usually passed from one person another through coughing and coughing. It is also transmitted through an infected mother to the child during birth or during labor. the birth of the child.
- The most common symptoms are stiff neck nausea vomiting, confusion and heightened the sensitivity to light.
- The causative agent is Neisseria gonorrhoeae.
- Also known as “the the clap” The gonorrhea disease is second in common in the world of sexually transmitted diseases (AIDS is the first) throughout the United States. The cause is the bacteria Neisseria gonorrhoeae, which is transmitted through sexual contact.
- Gonorrhea is a condition that if left untreated may cause serious complications. For women, complications such as the fallopian tube infection and uterus could be present. For men the bacterium could cause epididymis infection. According to a 2012 comprehensive review as well as global reports that this bacterial infection for men is affecting around 0.6 percent of the world population, whereas in women, it’s approximately 0.8 percent from the total population. In both genders infertility is by far the most significant complications.
13. Bubonic Plague
- The agent responsible for the disease is Yersinia pestis.
- It is caused by the bacteria Yersinia pestis Bubonic plague is thought as the most frequent kind of plague. This bacterial illness is generally caused by growth of lymph nodes (called buboes) in the armpits and groin.
- The bacterium is generally carried by the infected flea. In the past the bubonic plague was thought to be one of the most deadly bacterial diseases since it claimed the lives of over 50 million individuals during the 1300s.
- The causal agent is Treponema pallidum.
- The last but not least is a different bacterial illness that is which is transmitted through sexual contact. The bacteria Treponema pallidum is also passed on through physical contact and long-term kissing. Additionally, pregnant mothers who are infected are able to transmit the bacterium and the disease to their infants during labor and after birth.
- Syphilis is spread through sores and may cause damage to organs such as eyes, brain, or joints.
15. Necrotizing Fasciitis (Flesh-eating Disease)
- Necrotizing fasciitis is a severe condition that is often caused by Streptococcus pyogenes bacteria.
- S. Pyogenes are cocci-shaped bacteria that usually are found in the throat and skin parts of the body.
- S. Pyogenes are flesh-eating bacteria, which produce toxic substances that kill the body’s cells, including white and red blood cells. This causes the death of infected tissue, also known as necrotizing fasciitis.
- Other bacteria types that may cause necrotizing fasciitis are Escherichia Coli, Staphylococcus aureus Klebsiella and Clostridium.
- The development of this disease most often due to the infiltration by bacteria in the body via cuts or any other open wounds on the skin.
- Necrotizing fasciitis does not usually passed from person to another and the frequency of occurrences is unintentional.
- Healthy people with well functioning immune systems and who follow excellent wound care practices are less at risk of developing the disease.
- The Bacillary Dysentery condition is an inflammation in the intestinal tract caused by bacteria of the family of Shigella.
- Similar to cholera is transmitted through food and drinking water.
- Dysentery can also be spread by people who don’t wash their hands after using the toilet.
- Dysentery symptoms vary from mild to severe. The most severe symptoms are bloody diarrhea as well as high fever and discomfort.
- As with cholera, dysentery is usually treated with the process of hydration. The treatment can be done by using antibiotics depending on the its severity. The best method to avoid spreading Shigella clean then dry hands thoroughly prior to handling food items and avoid drinking water from local sources in areas where there could be a higher probability of contracting dysentery.
