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.
Microbes can also cause: Acute infections, which are short-lived. Chronic infections, which can last for weeks, months, or a lifetime. Latent infections, which may not cause symptoms at first but can reactivate over a period of months and years.
Even without antibiotics, most people can fight off a bacterial infection, especially if symptoms are mild. About 70 percent of the time, symptoms of acute bacterial sinus infections go away within two weeks without antibiotics.
Some bacterial pathogens can establish life-long chronic infections in their hosts. Persistence is normally established after an acute infection period involving activation of both the innate and acquired immune systems.
But infectious bacteria can make you ill. They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick. Examples of bacteria that cause infections include Streptococcus, Staphylococcus, and E.
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.
Bacterial infections, caused by harmful bacteria growing inside the body, show up in many forms. There are skin infections, respiratory tract infections, the dreaded “gastro” or food poisoning, sexually transmitted diseases and urinary tract infections.
Persistent bacterial infections such as Brucellosis and Typhoid Fever are characterized by a long incubation period to leads to chronic, sometimes lifelong, debilitating disease with serious clinical manifestations (1).
Sepsis happens when an infection you already have triggers a chain reaction throughout your body. Infections that lead to sepsis most often start in the lung, urinary tract, skin, or gastrointestinal tract. Without timely treatment, sepsis can rapidly lead to tissue damage, organ failure, and death.
The body reacts to disease-causing bacteria by increasing local blood flow (inflammation) and sending in cells from the immune system to attack and destroy the bacteria. Antibodies produced by the immune system attach to the bacteria and help in their destruction.
Resistance to even one antibiotic can mean serious problems. For example: Antimicrobial-resistant infections that require the use of second- and third-line treatments can harm patients by causing serious side effects, such as organ failure, and prolong care and recovery, sometimes for months.
The best known of the pathogens that cause persistent human infection include Mycobacterium tuberculosis, Chlamydia trachomatis, Treponema pallidum, Salmonella enterica serovar typhi (S. typhi), and Helicobacter pylori—a veritable “who's who” of human death and suffering.
The bacteria stop replicating and can remain in this dormant state for days, weeks or even months. When the immune system attack has passed, some bacterial cells spring back to life and trigger another infection.
Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing. The word antibiotic means “against life.” Any drug that kills germs in your body is technically an antibiotic.
Antibiotics usually cure bacterial infections. They sometimes go away on their own or can be treated without antibiotics, but it's always best to check with a healthcare provider for the best way to treat them.
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.
The following are signs you have a serious infection: Severe headache. Constant vomiting. Bloodstained vomit, stool, or urine.
Bacteria can infect every area of the body, like the bladder, brain, intestines, lungs, and skin. A bacterial infection can also spread throughout the blood, triggering a potentially life-threatening blood infection called septicemia.
The treatment may be very short, or it could go as long as several weeks, depending on the type of infection and how it reacts to the antibiotics. Sometimes, the infection will not go away, and your doctor may have to try a different type of antibiotic.
If you do feel more tired, fatigued or lethargic, it could just be a side effect of being sick. Your body is working hard to fight off a bacterial infection and needs rest to do its job effectively.
