Members of the public who want to find out more about how antibiotics work and the problems associated with their overuse, are invited to attend a public lecture on the topic.

The issue is set to be discussed as part of the Royal College of Surgeons' (RCSI) MiniMed Lecture Series on Wednesday, March 25.

Antibiotics are medicines used to treat bacterial infections. They do not work against viral infections, such as colds and flu. However, overuse of these drugs has led to a rise in antibiotic resistance and so-called ‘superbugs' such as MRSA. These bugs are acknowledged as one of the greatest potential threats to human health.

Consultant microbiologist, Dr Fidelma Fitzpatrick, and Cork GP, Dr Nuala O'Connor, will deliver the lecture, covering issues such as how antibiotic resistance occurs, how it spreads and how Ireland compares to other European countries.

"This session will give the public a better understanding of antibiotics, why and when you need them, their role in human health as lifesaving drugs and how everybody has a role in preserving these miracle drugs for future generations," the RCSI said.

The lecture is free of charge, however registration is essential as demand for places at previous lectures has outstripped availability.

The event takes place from 7pm to 9pm on March 25 at the RCSI, 123 St Stephen's Green. You can register online here
