Listeria with tumbling motility (by Pathmass)

Listeria monocytogenes

Gram+, aerobic, motile rod, facultative intracellular, beta hemolytic on blood agar

Tumbling motility in broth (as seen in video)

Jet motility in cells by actin filament formation

Listeriolysin O (Beta hemolysin): pathogenic factor, facilitates it scape from phagosome before phagolysosome formation and “jets” into another cell.

Diseases:

Lysteriosis: asymptomatic or diarrhea. 

Lysteriosis in pregnant women septicimia, crosses placenta.

Granulomatosis infantisepticum: neonatal disease, in utero transmission, sepsis, diseminated granulomas and high mortality.

Neonatal sepsis and meningitis (3° most common cause) 2-3 weeks after birth (fecal exposure)

Septicemia and meningitis in immunocompromised pts

Meningitis in renal transplant pts, cancer pts

Immuno

Recurrente infections with catalase positive organisms in Chronic Granulomatose Disease (CGD)

A fib =  no p wave 

ETC shortcuts

FADH2 goes to complex II since 2 hydrogens

RotenONE inhibits complex ONE

AntImIcIn A, 3 III’s ==> Antimycin A inhibits complex 3

Cyan COlored Complex IV ==> Cyanide and CO inhibit complex IV

24 brown fatty aspirins break up ==> 2,4 dnp, aspirin and brown fat are etc uncouplers 

Elek test to document toxi production of Corynobacterium diphteriae

That cell specialization…it’s pretty important.

(From our video)

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…

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
