Microscopic invaders surround you in your daily life, and most people don’t even realize it. From the drinking water you consume to the rug fibers beneath your feet, dangerous bacteria lurk around every corner. And unfortunately, it doesn’t take much effort to expose yourself to unhealthy microbes — and if they end up making you sick, it could lead to severe consequences. To help keep you safe, this article will delve into some common types of bacterium that can cause illness in humans.
Tuberculosis is a hazardous disease caused by Mycobacterium Tuberculosis, one of the most deadly bacteria on earth, as WHO puts it among the top ten causes of death worldwide. This bacteria is an airborne disease spread by Mycobacterium tuberculosis. It affects the lungs as well as other parts of the body.
Latent tuberculosis is a kind of disease that develops in individuals who have been exposed to TB but don’t show any symptoms. Latent infections are common, affecting up to 10% of the population. Typically it will then progress to active TB in around 10% of latent cases. The primary signs of active TB include persistent cough with blood-containing sputum, fever, night sweats, and weight loss. When individuals who have active TB in their lungs cough, spit, talk, or sneeze, tuberculosis is spread through the air.
Streptococcus is a bacteria that can cause various diseases, such as strep throat, scarlet fever, and flesh-eating disease. It is a leading cause of death in children under five years old. Streptococcus infection is transmitted by contact with respiratory secretions such as saliva, mucus, or blood. This may also spread through contaminated food or water.
The most common streptococcal symptoms include a sore throat, fever, and enlarged lymph nodes. Some strains of this bacteria can also cause nausea, vomiting, and diarrhea. Some examples of Streptococcus species that are not harmful and live in the human body are those that live in the mouth, the skin, the gut, and the upper respiratory system. Studies show that these Streptococcus species may protect against other harmful bacteria such as Staphylococcus aureus.
Treponema pallidum, a bacteria that causes syphilis, can infect almost any part of the body, depending on the stage of the illness. Early (primary, secondary, and early latent) and late (or tertiary) syphilis are two types of acquired syphilis. Depending on the stage at which syphilis manifests, the symptoms and indicators vary. Although multiple sores are not unusual, a single chancre is typical in the primary set of syphilis (complex, painless skin ulceration).
A general rash appears in secondary syphilis, which generally covers the palms and soles of the feet. Sores in the mouth or genital region are possible. There are few or no tertiary syphilis symptoms, except for gummas (Non-cancerous and benign growths) and neurological and heart problems. Syphilis is easily spread through intercourse. It may also be passed from one mother to her baby during pregnancy or shortly after birth, causing congenital syphilis.
Staphylococcus is a genus of Gram-positive bacteria that is one of the world’s most dangerous germs. The Staphylococcus genus includes at least forty different species. Although most of them are harmless and usually live on humans and other animals’ skin and mucous membranes, they are familiar. They may be found worldwide, but they are a minor element of soil microbe flora. Resistance to antibiotics has been reported to increase.
Another is methicillin-resistant Staphylococcus aureus (MRSA), which contains vancomycin-resistant and vancomycin-susceptible variants. MRSA, also known as drug-resistant staph infections, is responsible for various difficult-to-treat diseases in humans. Furthermore, any strain of S. aureus that has evolved through horizontal gene transfer and natural selection has multiple resistance to beta-lactam antibiotics.
MRSA is a severe bacterial infection that affects both animals’ and humans’ skin, soft tissues, and joints. People with this infection are 64% more likely to die than those who have a non-resistant strain of the illness.
The Klebsiella genus of bacteria is a nonmotile, Gram-negative, oxidase-negative, rod-shaped bacteria. Klebsiella is named after German-Swiss microbiologist Edwin Klebs. This species is found in human noses, mouths, and gastrointestinal tracts as part of the normal flora. However, they can also cause various illnesses, such as pneumonia, kidney infections, septicemia, meningitis, diarrhea, and soft-tissue infections.
Carbapenem antibiotics are the last line of defense for people infected with Klebsiella pneumonia. This type of antibiotic is used to treat very severe infections. Klebsiella pneumonia is a type of bacteria that can cause diseases like cholera. This was revealed in one of the exciting books called Current Diagnosis and Treatment in Infectious Diseases 1st Edition.
Salmonella is a genus of rod-shaped, flagellated, facultatively anaerobic enterobacteria. The species are motile and produce hydrogen sulfide. There are two types of Salmonella: Typhi and Paratyphi, which cause typhoid fever and paratyphoid fever. These bacteria can transmit through contaminated food or water.
Salmonella Enterica is a bacterial pathogen that causes food poisoning in humans. The most common symptom of salmonellosis, the infection caused by Salmonella, is diarrhea. Other symptoms include fever, vomiting, and abdominal cramps. Infections from this bacteria can be severe and sometimes fatal, especially in young children, the elderly, and those with weakened immune systems.
E. van Ermengem discovered the microbe in 1897 during an investigation of a food-borne epidemic in Ellezelles. Belgium botulism is a biological family of distinct cultures distinguished by their clostridia and produce. It also has a fungistatic effect, distinct neurotoxins with similar pharmacological activity. C. seven types of neurotoxins characterize botulinum, and each generation produces a new one. Food-borne botulism is somewhat uncommon, but it can kill swiftly, and products from contaminated sources may affect many people.
This illness is a severe public health problem that should be dealt with immediately. Botulism, as a result, represents a medical and public health emergency. To reduce the possibility of dying from botulism, prompt diagnosis and early therapy are necessary.
Tetanus is a severe, often fatal disease caused by the bacterium Clostridium tetani. The toxin secreted by C. Tetani causes rigidity and spasms of the voluntary muscles, including the jaw (lockjaw), leading to death.The bacteria that cause tetanus are found in soil and manure everywhere in the world.
Tetanus spores can survive for many years in unfavorable conditions. They enter the body through wounds, cuts, or scratches on the skin. Immunization with the tetanus toxoid vaccine is effective in preventing this disease. However, because immunity may decrease over time, booster doses of vaccines are necessary to protect against tetanus.
Be Aware Of These Dangerous Bacteria!
The most dangerous bacteria in our everyday lives come in many different shapes and sizes. Some of these are well-known, while others are not as well-known. However, all of these bacteria can cause severe illnesses and even death. Therefore, it is essential to be aware of these bacteria’s dangers and take steps to avoid them.
