Gram Negative Aerobic Rods Mnemonic

MICROBIOLOGY MNEMONIC 

BRUno, FRANCISco & COnstantine are BORing PSEUDO LEGIONnaires

Brucella sp 

Francisella tularensis 

Coxiella burnetti

Bortedella pertusis

Pseudomona aeuroginosa

Legionella pneumophila

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

Indwelling catheter associated UTI

Catheter induced UTI

Typical :e.coli,Klebsella pneumonia,staph.saprophticus,proteus.mirabilis(lactose fermenters)(eat protein to be the cool member of the sapron staff club)

Atypical opportunistic:Pseudomonas aeroginasa.(non lactose fermenter)

Summery of UTIs

E.coli and klebsella are leading cause of uti..

staph saprophticus  uti in sexually active women.

Enterococi(strptococcus family ) oppurtunistic uti

U.urealyticu known cause of urithritis but needs special media rich in urea and cholestrol

Medically Important Bacteria: Clasification

My revised pnemonic for ADP ribosylation A-B toxins

Boring     and      serious      people score high in usmle…

Bordetella pertussis and B.cereus  increases   cAMP by inhibiting Gi

Cool    and     Vibrant   people  also score high…

E. coli  and Vibreo cholerae increases cAMP by  activating Gs

Exception: Please please please remember that  Bacillus anthracis has an edema factor which it self acts as adenylate cyclase…. no ADP ribosylation involved..so hence  cAMP level increases.

Me durning finals.
