Antibiotics work by either selectively killing (bactericidal) or inhibiting the growth (bacteriostatic) of bacteria. Infections with a high bacterial burden, such as those seen in infective endocarditis, require treatment with antibiotics with rapid bactericidal activity.

They can cause bacteria to become increasingly resistant to treatment, for example, and destroy healthy flora in the gut. Now, a new study from Case Western Reserve University shows that antibiotics can damage immune cells and worsen oral infections.
Why do doctors think carefully about prescribing antibiotics?
Improving prescribing General practitioners believed that people with severest symptoms are at risk of bacterial complications and that prescribing antibiotics will prevent or reduce such complications.
When choosing an antibiotic, what should your doctor consider?
When choosing an antibiotic, your doctor first considers the type of bacteria involved. 1 The type of bacteria can help determine which antibiotic drugs to choose, since not all antibiotics affect all bacteria.

What class of antibiotics kill bacteria?
Antibiotics are further divided into bactericidal antibiotics (which kill bacteria) and bacteriostatic antibiotics (which stop them from growing). For some infections, limiting bacterial growth is sufficient enough ...
How to avoid infection?
Focus instead on avoiding infections by following three simple tips: 2 1 Get vaccinated for both bacterial and viral infections. Speak with your doctor about which ones you need or are missing. 2 Wash your hands. This is not about being germ-phobic. It's about understanding that your hands are among the most effective vectors of infection. Wash thoroughly, ideally with an antibacterial wash, whenever you are in a public place where you might pick up a bug. 3 Cover your mouth when you sneeze or a cough. Try to avoid doing so into your hands as this can spread an infection to others. Instead, use a tissue or the crook of your elbow. If in a confined space such as an airplane, consider wearing a disposable mask if you are ill or at risk of infection.
What happens if you don't take antibiotics?

Why are antibiotics important?
Antibiotics are among the most important interventions in healthcare. Resistance of bacteria to antibiotics threatens the effectiveness of treatment. Systematic reviews of antibiotic treatments often do not address resistance to antibiotics even when data are available in the original studies.
How does antibiotic resistance affect the world?
Author Summary Antibiotic resistance is a growing problem that the World Health Organization describes as “one of the top three threats to global health.” To date, bacteria have developed resistance to all antibiotics used in clinical settings. Unfortunately, the evolution of antibiotic resistant bacteria is accelerating, as antibiotics continue to be misused and overused. As the antibiotic pipeline is drying up, it becomes increasingly critical to utilize the antibiotics already on the market more effectively. The key to designing better regimens lies in the ability to predict how bacteria will respond to a particular antibiotic treatment. Because of this, we need a simple metric that characterizes this pathogen-antibiotic interaction that can be easily measured and used to design dosing protocols that will effectively clear an infection. To help guide the design of effective protocols, we use quantitative modeling to develop a metric that is easy to measure and quantifies the pathogen-antibiotic interaction. Through optimized antibiotic regimens, our strategy could extend the use of first-line antibiotics, improve treatment outcome, and preserve last-resort antibiotics.
What to know before prescribing antibiotics?
Firstly: Make sure you know normal flora and the causes of common infections. Know your specialities serious and common infections, the micro-organisms that cause these and the usual treatments for them.
What is the treatment of an infection?
Treatment is the use of antibiotics to eliminate infection from an already infected site. Treatment and duration of treatment varies between clinical conditions ( see section - Clinical Scenarios for individual conditions).
What to do if your doctor says antibiotics are the best treatment?

Abstract
Many studies have investigated the ways in which physicians decide whether to prescribe antibiotics, but very few studies have focused on the reasons for which general practitioners (GPs) choose to prescribe a particular antibiotic in a specific clinical situation.
Background
Antibiotic misuse is a major public health problem worldwide. One sort of misuse is the prescription of the wrong antibiotic molecule by the physician [ 1 ]. Such errors expose patients to the unnecessary risk of adverse effects, complications, and death [ 2 ], and the population to the risk of resistant bacteria emerging [ 3 ].
Methods
We used a three-step process to explore the rationale used by GPs to choose a particular antibiotic for a specific clinical situation:
Results
Interviews with 20 GPs and the data from three publications [ 21, 22, 23] were analysed.
Discussion
We conducted a qualitative research study, to explore the rationale used by GPs in their choice of an antibiotic in a specific clinical situation. We showed that GPs considered various factors when selecting the antibiotic to prescribe: factors relating to microbiological aspects (e.g. bacterial resistance), pharmacology (e.g.
Conclusions
When GPs decide which antibiotic to prescribe, they do not limit themselves to those recommended in clinical practice guidelines. They use their knowledge and experience to guide their choice of antibiotic, but they also take into account factors relating to microbiology, pharmacology, and clinical conditions.
