Q10 – Remembering antibiotics and their classes

Our JMO pre-test survey also asked “What puzzles you about antibiotics and their use”. A recurring theme was concern about remembering the various classes and names of antibiotics. Here are some useful pointers and a short quiz ! 

Q3 Tragedy of the commons and antimicrobial stewardship

Question 3 of our JMO pre-test survey asked about the aims of antimicrobial stewardship (yes, better ‘antimicrobial’ than ‘antibiotic’- antiviral, antifungal, antiparasitic resistance are issues as well). We gave you three options  and all except one responded with the correct answer – all three!  The order is important – treatment of the individual patient comes first: Optimise the effectiveness […]

Q2 Understanding antibiotic resistance and Staphylococcus aureus

Q2 in our JMO pre-test asked: “What is the main mechanism by which the bacterium Staphylococcus aureus becomes resistant to penicillin?” We gave alternatives enumerating basic mechanisms that micro-organisms use (often in combination) to become resistant to an antimicrobial agent (graphic below).   Production of penicillinase (i.e. inactivation by a type of beta-lactamase) was the correct answer– more […]

Antibiotic classes – why so important to know about them?

The antibiotic knowledge survey of our new interns this week,  showed that many were confused about which class vancomycin (a glycopeptide) fell into (30% thought it was an aminoglycoside).  This is a potentially dangerous confusion as the dosing, side effects and monitoring all differ substantially between these classes: Aminoglycoside Glycopeptide Indicative agents Gentamicin Vancomycin Dosing […]
