A healthy immune system can defeat invading disease-causing germs (or pathogens), such as bacteria, viruses, parasites—as well as cancer cells—while protecting healthy tissue. Understanding how the immune system works and how we can help protect our bodies is essential to the fight against the COVID-19 pandemic.
Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics.
Most bacterial infections can be effectively treated with antibiotics. They either kill bacteria or stop them multiplying. This helps the body's immune system to fight the bacteria. Your doctor's choice of antibiotic will depend on the bacteria that is causing the infection.
The phagosome is where bacteria are normally trapped and killed but escaped bacteria can grow and spread, causing serious infection. “We know that some immune cells can detect when bacteria escape these phagosomes. One way is using autophagy, a process that evolved to recycle old or broken parts of cells.”
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.
Urinary tract infections (UTI)
UTIs are mainly caused by the bacterium Escherichia coli (E. coli) and are the most common infection in humans worldwide.
Common bacterial diseases include UTIs, food poisoning, STIs and some skin, sinus and ear infections. They're often treated with antibiotics.
Your doctor may need a sample of your urine, stool or blood, or a swab from your nose or throat to see what sort of infection you have. If you have symptoms on an infection, it is important to know if it is caused by bacteria or viruses, because the treatments differ.
An untreated bacterial infection can also put you at risk for developing a life-threatening condition called sepsis. Sepsis occurs when an infection causes an extreme reaction in your body. The bacteria most likely to cause sepsis include Staphylococcus aureus, E. coli, and some types of Streptococcus.
Share on Pinterest General symptoms of a bacterial infection include fever, chills, exhaustion, and headache. The signs and symptoms of a bacterial infection typically depend on where in the body the infection occurs. gastrointestinal symptoms, such as: nausea.
A blood culture test helps your doctor figure out if you have a kind of infection that is in your bloodstream and can affect your entire body. Doctors call this a systemic infection. The test checks a sample of your blood for bacteria or yeast that might be causing the infection.
Bacteria must enter your body for them to cause an infection. So you can get a bacterial infection through an opening in your skin, such as a cut, a bug bite, or a surgical wound. Bacteria can also enter your body through your airway and cause infections like bacterial pneumonia.
Anyone can get sick when exposed to bacteria. But, having a weakened immune system puts you at a higher risk of severe bacterial infections.
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.
In many cases, you only need to take antibiotics for a week or two to fully recover from an infection.
Secondary bacterial infections develop in patients during or after initial infection with an infective pathogen, often a virus (Morris et al., 2017; Wang et al., 2018) and are associated with high morbidity and mortality rates (Figure 1) (Mallia et al., 2012).
Garlic: contains the most powerful natural antibiotic “allicin“. Due to its antiviral effect, garlic can fight harmful bacteria, viruses and fungi. It also has a mild blood thinning and blood pressure lowering effect, which can be beneficial for cardiovascular diseases.
Option 1: Honey
Honey is one the oldest known antibiotics, tracing back to ancient times. Egyptians frequently used honey as a natural antibiotic and skin protectant. Honey contains hydrogen peroxide , which may account for some of its antibacterial properties.
