Leukocyes (WBCs) & Defence

A summary

Neutrophils -  non-specific defence against bacteria and fungi

Eosinophils -Defence against parasites; dampen allergic response

Basophils  - Anaphylactic & inflammation response

Monocytes - Mature into macrophages, engulf foreign substances;  remove aged RBCs and other debris

Lymphocyes - Recognise antigens, various roles

I made a lymph drainage sticker for the immuno section of first aid

How to remember Lysteria monocytogenes tumbling motility?

MICROBIOLOGY MNEMONIC

So, Lysteria rhymes with Hysteria, and when I think of hysteria I think of someone dancing Hysterically…..(actually, me dancing hysterically..)

I also googled Hysteria, and found this:

HYSTERIA RADIO!

So here it goes: “Lysteria dances to  Hysteria Radio”

If I don’t come up with all these silly associations my brain melts and confuses all the freakin bacterias, so bear with me…

Careers:

A future in Chemistry

What can I do with my chemistry degree?

Chemistry Careers - American Chemical Society

What to do with a degree in chemistry - The Guardian

Micobacterium tuberculosis DX

Auramine-Rhodamine staining bacilli: fluorescent apple green (sensitive but not specific). If positive, do acid fast.

Acid Fast

Lowenstein-Jensen medium: aerobic, slow growing (2-3weeks)

PPD or Mantoux Test: measure 48-72h after. POSITIVE: >/= 5mm in VIH+ pts, >/=10mm in high risk population (IVDA, poverty, immigrants from high TB area, physicians, nurses), >/=15mm in low risk population

Positive indicates exposure, but not necessarily active disease.

Quantiferon-TB Gold Test: measures IF-gamma

Niacin producers

Catalase negative at 68° and catalase active at body T°

No serodiagnosis

Strep throat.
