RCPath fees for examinations 2026

RCPath lists Medical Microbiology Part 1 as an early assessment of scientific microbiology, virology and infection knowledge, using a single 3-hour paper with 125 questions in one-best-answer and extended-matching formats. RCPath route guidance adds that many UK medical infection trainees sit Part 1 Infection/CICE before Part 2 Microbiology, while Part 1 Medical Microbiology and Virology is the one-paper route for HSST scientific trainees and some overseas candidates. Part 2 Medical Microbiology is a closed-book two-day examination with four equally weighted papers: Paper 1 essay plus SAQs, Paper 2 critical appraisal plus SAQs, Paper 3 complex clinical and laboratory scenarios, and Paper 4 OSPE. The 2026 fee schedule lists Part 1 MMV at GBP 749 and Medical Microbiology Part 2 at GBP 1,576.

A.Proteus mirabilis
B.Escherichia coli
C.Vibrio cholerae

A.Curved motile rods growing in microaerophilic conditions
B.Pseudomonas aeruginosa
C.Clostridioides difficile
D.Haemophilus influenzae
Explanation: P. aeruginosa is oxidase positive and may produce pyocyanin pigment.
7Campylobacter jejuni is best associated with which microscopy and growth feature?
A.Clostridioides difficile
B.Haemophilus influenzae
C.Curved motile rods growing in microaerophilic conditions
D.Neisseria gonorrhoeae
Explanation: Campylobacter are curved motile Gram-negative rods requiring microaerophilic incubation.
8A strict anaerobe causing antibiotic-associated colitis is most often detected by toxin testing for which organism?
A.Haemophilus influenzae
B.Neisseria gonorrhoeae
C.Staphylococcus aureus
D.Clostridioides difficile
Explanation: C. difficile causes toxin-mediated colitis, especially after antibiotic exposure.
9Small Gram-negative coccobacilli requiring X and V factors suggest which respiratory pathogen?
A.Haemophilus influenzae
B.Neisseria gonorrhoeae
C.Staphylococcus aureus
D.Streptococcus pneumoniae
Explanation: H. influenzae requires haemin and NAD, known as X and V factors.
10A Gram-negative diplococcus from urethral discharge that is oxidase positive and grows on selective media suggests what?
A.Staphylococcus aureus
B.Neisseria gonorrhoeae
C.Streptococcus pneumoniae
D.Vibrio cholerae
Explanation: N. gonorrhoeae is an oxidase-positive Gram-negative diplococcus causing urethritis and cervicitis.

About the FRCPath Medical Microbiology Exam

FRCPath Medical Microbiology is the RCPath fellowship examination pathway assessing microbiology and infection knowledge, laboratory practice, antimicrobial resistance interpretation, infection prevention, public health judgement and consultant-level clinical microbiology decision making.

Assessment

Part 1 MMV is a 125-question MCQ/EMQ paper. Part 2 Medical Microbiology has four papers over two days: essay/SAQ, critical appraisal/SAQ, complex clinical and laboratory scenarios, and OSPE.

Time Limit

Part 1 MMV 3 hours; Part 2 papers are 2.5 hours, 2.5 hours, 3 hours and 3 hours.

Passing Score

Part 1 uses objective standard setting. Part 2 requires passing both combined Paper 1/2 and Paper 3/4 components in the same sitting.

Exam Fee

2026 RCPath fees: Medical Microbiology and Virology Part 1 GBP 749; Medical Microbiology Part 2 GBP 1,576. (Royal College of Pathologists)

FRCPath Medical Microbiology Study Tips from Top Performers

1Build organism identification and clinical syndrome reasoning together rather than memorising organisms in isolation.
2Review AST interpretation with resistance mechanisms, breakpoints, stewardship implications and infection site.
3Practise Part 2-style written answers for infection prevention, laboratory safety, critical appraisal and service management.
4Use recent local and national guidance for notifiable disease, high-consequence pathogens and outbreak response.
5Track errors by domain: organism ID, specimen quality, AST interpretation, IPC action, stewardship or communication.
