What are the symptoms of Salmonella?
The symptoms of Salmonella food poisoning are fever, abdominal cramps, vomiting and diarrhoea. The Food Poisoning - Salmonella Infection notes cover this in full.
What are the symptoms of gonorrhoea?
The main symptoms of gonorrhoea are a thick yellow or green discharge from the vagina or penis and pain or a burning sensation when urinating, and in some cases pelvic pain or swollen testicles. The Sexually Transmitted Infections - Gonorrhoea notes cover this in full.
What are the side effects of statins?
Statins can cause side effects such as muscle pain. The Evaluating Cardiovascular Disease Treatments notes cover this in full.
What is a pathogen?
A pathogen is a microorganism that causes infectious disease. The Types of Pathogens and How They Spread notes cover this in full.
Who discovered penicillin?
Alexander Fleming discovered penicillin by accident in 1928, when a mould killed bacteria in his petri dish. The How Antibiotics Work and Their Limitations notes cover this in full.
What is MRSA?
MRSA (methicillin-resistant Staphylococcus aureus) is a strain of Staphylococcus aureus bacteria that has evolved resistance to methicillin and many other commonly used antibiotics. The How Antibiotic Resistance Develops notes cover this in full.
How long do antibiotics take to work?
Antibiotics take 24-48 hours to work, while painkillers work immediately. The Treating Symptoms vs Killing Pathogens notes cover this in full.
