MRCPath Part 1 in Medical Microbiology & Virology Extended matching question (EMQ) samples
These sample questions will allow you to become familiar with the style of the questions
that will be used in the MRCPath Medical Microbiology & Virology Part 1 Examination.
They also serve to illustrate the breadth of the topics that will be covered. Please note
that this is not intended to be a “mock” examination and answers are therefore not
provided. Question 1

Hypochlorite solution (125 parts-per-million available chlorine)
Sodium dichloroisocyanurate granules or tablets (e.g. ‘Presept’)

A 17 year old heterosexual male presents to his general practitioner with a 24 hour history of painful dysuria and a thin urethral discharge. Nothing abnormal is found on examination. A Gram-stained smear of a uretheral swab shows numerous pus cells and scattered intra-and extra-cellular Gram-negative diplococci.
A 30 year old heterosexual male treated for gonococcal urethritis returns to the surgery 5 days later with a relapse of dysuria and urethral discharge. Bacterial culture of a urethral swab is reported as negative.
A 38 year old homosexually-active male presents with a painless ulcer at the anal margin. He has had a steady partner for 5 years and not left the UK during the past 2 years, but had receptive anal intercourse with a new partner 3 weeks ago.
A 25 year old female presents with a short history of severe vulvo- vaginal inflammation and whitish discharge. She denies having had intercourse for the past month. Two weeks ago she had an episode of dysuria which was treated by her general practitioner with a 5 day course of amoxicillin.
