Antibiotic Resistant Bacteria
Informed by recognized medical guidance
Overview
Antibiotic-resistant bacteria are germs (bacteria) that have learned to survive the medicines designed to kill them. These antibiotics no longer work well, so infections caused by these bacteria are harder to treat and can make you sick for longer.
Key facts
- Antibiotic resistance happens naturally, but overusing or misusing antibiotics makes it worse.
- Resistant infections can happen in the community, in hospitals, and in long-term care facilities.
- Taking antibiotics exactly as prescribed and only when needed helps slow down resistance.
Yes, antibiotic-resistant bacteria are a major health problem worldwide. Common types include MRSA (a type of Staph bacteria) and certain gut infections that are harder to treat.
Anyone can get an antibiotic-resistant infection, but people with weakened immune systems, chronic illnesses, or those who are hospitalized or in long-term care are at higher risk.

- Difficulty breathing or choking
- Severe chest pain or pressure
- Fainting, collapse, or unresponsiveness

- ⚠Severe headache or stiff neck
- ⚠Widespread rash or a rash that doesn't fade when pressed
- ⚠A wound that is very painful, swollen, or draining pus
- ⚠Persistent vomiting or not being able to keep down fluids
Common symptoms
- Fever
- Chills or sweats
- Cough that doesn't get better
- Pain or burning when urinating
- Wounds that become red, hot, or ooze fluid
- Feeling unusually tired or unwell
Symptoms in children
- Fever that keeps coming back
- Listlessness or low energy
- Poor feeding or fluid intake
- Irritability or unexplained crying
- Ear pain or pulling at the ears
Symptoms in older adults
- Confusion or sudden changes in alertness
- Falls or weakness
- Loss of appetite
- Fever or low body temperature
- Breathlessness or fast breathing
Causes
Main causes
- Taking antibiotics when they are not needed, such as for a virus or minor infection
- Stopping antibiotics early before the infection has cleared
- Shared use of leftover antibiotics or saving them for later
- Poor hand hygiene and wound care that allow bacteria to spread
- Hospitals and care facilities where resistant bacteria can move between people
Risk factors
- Recent or frequent use of antibiotics
- Hospitalization or surgery in the last few months
- Living in a nursing home or long-term care facility
- A weakened immune system due to illness or treatment
- Chronic conditions such as diabetes or lung disease
When to see a doctor
See a doctor urgently if:
- You suspect a serious infection or your symptoms are getting worse quickly.
- You have a high fever, are very confused, or feel faint.
- You are caring for a young child or an older adult who seems very ill.
Book a routine appointment if:
- Your symptoms have lasted longer than a few days without improving.
- You have a cough, urinary pain, or a wound that isn't healing.
- You have had a previous antibiotic-resistant infection and want guidance.
Diagnosis
A healthcare professional will ask about your symptoms, recent health, and antibiotic use. To check for resistant bacteria, they may take a sample (such as urine, a wound swab, or blood) and send it to a laboratory.
Tests that may be done
- Culture and sensitivity test: grows the bacteria and checks which antibiotics are most effective
- Blood tests: look for signs of infection or inflammation
- Urine test: checks for bacteria in the bladder or kidneys
What to expect at your appointment
Your clinician may need to adjust your treatment once results come back. This can take a day or two. In the meantime, they may start a broad-spectrum antibiotic and then change to a more targeted one when they know which antibiotic will work best.
Treatment
Treating an antibiotic-resistant infection requires a doctor's guidance. The goal is to choose a medicine that still works against the specific bacteria, while also caring for your symptoms and preventing the infection from spreading.
Self-care at home
- Take all antibiotics exactly as directed, even if you feel better.
- Drink plenty of fluids and rest.
- Use over-the-counter fever or pain relief only as recommended by your doctor or pharmacist.
- Keep a wound clean and covered.
- Wash your hands often, especially after using the toilet or touching pets.
Medical treatments
Depending on the type and location of the infection, treatment may involve antibiotics given by mouth or through a drip (intravenously) in the hospital. Sometimes two or more antibiotics are used together. Your doctor will choose a plan based on laboratory results and your medical history.
When is surgery considered?
In some cases, surgery may be needed to drain an abscess (a pocket of pus) or remove infected tissue. This is not common and is always done by a specialist.
Living with this condition
If you have had a resistant infection, it is important to finish your treatment, keep follow-up appointments, and practice good hygiene. Let your healthcare team know about your history of resistant bacteria before any procedure or future medical visit.
Lifestyle tips
- Wash your hands with soap and water or use alcohol hand gel.
- Cover your mouth and nose when coughing or sneezing.
- Avoid sharing personal items like towels, razors, or drinking cups.
- Stay up to date with recommended vaccinations.
- Clean high-touch surfaces at home regularly.
Diet and exercise
Eating a balanced diet with plenty of vegetables, fruits, whole grains, and lean proteins supports your immune system. Gentle physical activity, like walking, can help you regain strength after an infection, but listen to your body and rest when needed.
Mental health and emotional wellbeing
Dealing with a difficult or repeated infection can be stressful and worrying. It may affect your mood or energy. It is normal to feel frustrated, and talking to your doctor or a counselor can help.
Prevention
Yes, antibiotic resistance can be slowed down. The best steps are to use antibiotics only when prescribed, take them correctly, and prevent infections through hand hygiene, safe sex, and good food handling. These actions protect you and others.
Vaccines
Vaccines can prevent some bacterial infections, such as those that cause pneumonia, tetanus, and whooping cough. Ask your doctor which vaccinations are recommended for you.
Screening programmes
If you are at high risk, such as having a planned hospital stay or a weakened immune system, your doctor may check for certain resistant bacteria, like MRSA, before a procedure. This helps protect you and others.
Complications
If left untreated
- The infection may spread to other parts of the body, such as the blood, lungs, or bones.
- Sepsis, a life-threatening response to infection, can develop.
- Treatment becomes more complicated and may require longer hospital stays.
- The infection may make it harder to recover from surgery or other illnesses.
Long-term outlook
Antibiotic-resistant infections are serious, but medical teams have many ways to treat them. New antibiotics and treatment strategies are being developed. With proper care, most people can fully recover. Your best partner is your healthcare provider, who can guide you through the right treatment and prevention steps.
