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. As much as 13% of cases are resistant to most antibiotics, and about 6% are resistant or unresponsive to essentially all treatment.
Septicaemia is a serious blood infection. It is when bacteria enter the bloodstream and cause blood poisoning. Sepsis is a condition that happens when the body damages its own tissues in response to a bad infection. Sepsis can cause shock, organ failure and death if it's not treated quickly.
Methicillin-Resistant Staphylococcus Aureus
This type of bacteria is resistant to many antibiotics, including methicillin. Most methicillin-resistant Staphylococcus aureus, or MRSA, infections contracted outside of a hospital are skin infections.
Legionnaire's disease is associated with outbreaks of sudden death. The disease is caused by Legionella pneumophila, a facultative intracellular organism. It causes severe pneumonia in the elderly, in smokers, and in immunocompromised patients.
The most extreme extremophile that is known at the moment is the Deinococcus radiodurans. This microbe can survive extreme cold, drought, thin air and acid. It has even been found on the walls inside nuclear reactors, where the radioactivity would be instantly fatal for humans.
Sepsis is the body's extreme response to an infection. It is a life-threatening medical emergency. Sepsis happens when an infection you already have triggers a chain reaction throughout your body.
Streptococcal toxic shock syndrome (STSS) is a rare, but serious bacterial infection. STSS can develop very quickly into low blood pressure, multiple organ failure, and even death.
Convalescence. The final stage of infection is known as convalescence. During this stage, symptoms resolve, and a person can return to their normal functions.
Many viral and bacterial infections can be treated at home or with urgent care. However, you may need go to the emergency room if your symptoms are severe or if you are in a high-risk group.
Yet, many bacteria directly manipulate their host cell in various phases of their infection cycle. Such manipulations can affect host cell integrity and can contribute to cancer formation.
Symptoms in case of acute Bacterial Infections may get resolved spontaneously in a duration of approx. two weeks, without undergoing treatment. However, in chronic cases when the symptoms persist for a longer duration, such as for 10 or more days, there is a need for the consultation with a doctor.
Sepsis can develop quickly from initial infection and progress to septic shock in as little as 12 to 24 hours. 1 You may have an infection that's not improving or you could even be sick without realizing it.
If the infection has spread or you have a generalized infection, you may develop other signs and symptoms, such as fever, fatigue, pain, etc. Sometimes however, you may have an infection and not know it, and not have any symptoms.
Urinary tract infections (UTI)
UTIs are mainly caused by the bacterium Escherichia coli (E. coli) and are the most common infection in humans worldwide. Symptoms include a burning sensation when urinating, blood in the urine, and strong-smelling urine.
coli, King Of All Bacteria.
The superbug in question is Acinetobacter baumannii, which the World Health Organization has classified as a “critical” threat among its “priority pathogens” – a group of bacteria families that pose the “greatest threat” to human health.
One common superbug increasingly seen outside hospitals is methicillin-resistant Staphylococcus aureus (MRSA). These bacteria don't respond to methicillin and related antibiotics. MRSA can cause skin infections and, in more serious cases, pneumonia or bloodstream infections.
