Infectious disease is the study of a disease or disease-causing organism liable to be transmitted to people, organisms, etc. through the environment. Medicos Library has provided high standard Infectious disease Notes by Dr. Yousif Abdallah Hamad.
Summary of Notes:
Identifying gram-positive bacteria
Gram positive bacteria will turn purple/blue following the gram staining. Microscopy will then reveal the
shape, either cocci or rods.
makes catalase: Staphylococci
does not make catalase: Streptococci
makes coagulase: S. aureus
does not make coagulase: S. epidermidis (novobiocin sensitive), S. saprophyticus (novobiocin
partial haemolysis (green colour on blood agar): α-haemolytic
optochin sensitive: S. pneumoniae
optochin resistant: Viridans streptococci
complete haemolysis (clear): -haemolytic
bacitracin sensitive: Group A: S. pyogenes
bacitracin resistant: Group B: S. agalactiae
no haemolysis: γ-haemolytic
Staphylococci are a common type of bacteria which are often found normal commensal
organisms but may also cause invasive disease.
Staphylococci are skin organisms most commonly introduced during pacemaker insertion
and such a discitis would present with back pain.

How to use the notes to study for MRCP:
- Initially, you need to skim through the notes at least twice to build up an idea about the syllabus of MRCP. Highlight any portion that is difficult so that you can concentrate on that during your revision.
- Next proceed to the question banks. You can choose to do Passmedicine, onexamination or Pastest. I usually recommend students to do Passmedicine and the Pastest.
- As you go through the questions make a super-revised notes of your own. Write down in one sentence what you learned from the question you just attempted.
- If you get any question wrong or you get confused then return to the notes and re-read one more time before attempting the question again. And write down the point in red in you revision notes so that you can skim through it easily during your revision.
- I have highlighted some points in yellow and green to help you concentrate on those points. As you go through passmedicine and pastest, you can highlight the points further to help in your revision.
- During your revision before the main exam, only read the highlighted portions including those that you highlighted when practicing the question bank. And also read your super-revised notes that you made from the question banks.
I believe these method has worked for many students and will help you in your journey to be successful in MRCP part 1 and as well as build your basics for Part 2.
