There isn't one single "most severe" bacterium, but Mycobacterium tuberculosis (TB) is a leading infectious killer globally, causing millions of deaths yearly, with drug-resistant forms posing critical threats. Other severely dangerous bacteria include multidrug-resistant Gram-negative bacteria like Klebsiella pneumoniae, E. coli, and Acinetobacter baumannii, especially those causing sepsis, pneumonia, and bloodstream infections in healthcare settings, notes the World Health Organization (WHO).
The most deadly bacterial disease contracted by human beings is mycobacterium tuberculosis, the world's leading infectious disease with more than 1,700,000 deaths per year.
Deinococcus radiodurans is named by the Guinness Book of World Records as the world's toughest bacteria.
A Brief Introduction to the Top 3
The top 3 bacterial infections are Strep Throat, Urinary Tract Infections (UTIs), and Bacterial Pneumonia.
Deinococcus radiodurans is the “toughest bacterium known” due to its remarkable ability to tolerate various environmental stresses, including nuclear radiation, extreme temperatures, vacuum, or oxidation. It can even survive for years in outer space.
Any bacteria can become resistant to antibiotics, but there are some that become superbugs more often. Examples of bacteria with superbug strains include:* Staphylococcus aureus (like MRSA). Carbapenem-Resistant Enterobacterales (CREs) and other drug-resistant Enterobacterales.
Bacteria are microscopic single-celled organisms that live in almost every environment on Earth, from deep-sea vents to human digestive tracts. They are prokaryotes, lacking a membrane-bound nucleus.
MRSA is one of the most common antibiotic-resistant bacteria. Symptoms of MRSA infection often begin as small red bumps on the skin that can progress to deep, painful abscesses or boils, which are pus-filled masses under the skin.
However, over the past 25 y it has been shown that gram-positive bacteria are the most common cause of sepsis. Some of the most frequently isolated bacteria in sepsis are Staphylococcus aureus (S. aureus), Streptococcus pyogenes (S. pyogenes), Klebsiella spp., Escherichia coli (E.
The bacteria and viruses that cause the most illnesses, hospitalizations, or deaths in the United States are described below and include:
Deinococcus radiodurans. Deinococcus radiodurans is a bacterium, an extremophile and one of the most radiation-resistant organisms known. It can survive cold, dehydration, vacuum, and acid, and therefore is known as a polyextremophile.

The all-age mortality rate was 99·6 deaths (74·2–132) per 100 000 population collectively for these pathogens. Only one organism, Staphylococcus aureus, was associated with more than 1 million deaths in 2019 (1 105 000 deaths [816 000–1 470 000]; table).
Among bacteria, the best adapted group to various extreme conditions is the cyanobacteria. They often form microbial mats with other bacteria, from Antarctic ice to continental hot springs.
Has the employee been diagnosed with Norovirus, E. coli, Shigella, Hepatitis A, or Salmonella Typhi or do they have jaundice or a sore throat with a fever? Exclude employee from work. Contact the Health Department immediately.
Melioidosis is an infectious disease caused by the bacteria Burkholderia pseudomallei that are commonly found in the soil and water. Melioidosis is a rare disease in the United States, but it is common in tropical or subtropical areas of the world, including Southeast Asia, Africa, and Australia.
Mycobacterium tuberculosis is the world's leading infectious killer, causing more than 1.7 million deaths every year. One of the reasons this bacteria is so deadly is its ability to hide inside our cells.
Early symptoms of sepsis may include:
You get sepsis when your body has an extreme, damaging reaction to an infection (bacterial, viral, fungal, or parasitic), causing its own immune response to harm tissues and organs, leading to potential organ failure; it starts with any infection, like pneumonia, UTI, or a skin wound, and becomes a medical emergency when the body's defense system overreacts.

Necrotizing fasciitis is a rare, but serious bacterial infection. It can develop very quickly into a life-threatening emergency. Early symptoms include fever, severe pain, and an infection that spreads quickly. People with necrotizing fasciitis need immediate hospital care, antibiotics, and surgery.
Bacteria can cause a range of infections and illnesses, for example:
Urine contains fluids, salts and waste products but is sterile or free of bacteria, viruses and other disease-causing organisms. A UTI occurs when bacteria from another source, such as the nearby anus, gets into the urethra. The most common bacteria found to cause UTIs is Escherichia coli (E. coli).
