Micro Of Uti

Front 1

**which organisms overlap bw causes of UTI and STD

Back 1

gonococcus
chlamydia
they cause.....

Hint 1

urethritis but are transmitted by sex

Front 2

3 reasons why UTI are more frequent in women than men
- name common 6 common organisms and they're way of infection
- which one is the most common

Back 2

1-shorter urethra, prevalent in 20-50y/o
2-unique receptors on uroepi cells
3- men have anti-microbial prostatic secretions.

Hint 2

E.coli,
Proteus,
Enterobacter,
Klebsiella, Enterococcus,
Staph.(esp saprophyticus)
they migrate from the skin or GI
the most common is e-coli

Front 3

this advanced condition affecting the GU tract typically present w hypotension and low flank pain
- what condition is this
- other presenting symptoms

Back 3

pyelonephritis

Hint 3

also may pw fever, bacteremia, sepsis

Front 4

list the most common organisms that cause prostatitis
- gram negatives
- and which gram positives?

Back 4

gram neg (-)
enterics primarily:
- MC- e.coli
- ST--- klebsiella, proteus
- least---pseudomona, enterobacter, serratia

gram (+) ?----->

Hint 4

rare except for enterococci

Front 5

A patient presents w fever, dysuria, frequency, BOO, and a tender prostate
- diagnosis
- precautions in PE

Back 5

acute prostatitis

Hint 5

avoid prostatic massage bc it may induce bacteremia

Front 6

male pt with h/o BOO now p/w LBP, low grade fever, myalgias, arthralgias...
- most likely condition
- this patient would be at risk for what, as a complication of his condition

Back 6

chronic prostatitis

Hint 6

it may be a reservoir for recurrent UTI.s

Front 7

ideal diagnostic modality for prostatitis
- treatment approach

Back 7

urine
blood culture
or both

Hint 7

often empirically to include coverage for most enteric derived bacteria

Front 8

the most common cause of NON-gonococcal urethritis
- way for transmission

Back 8

chlamydia

Hint 8

causes an atypical form of urethritis that arises from an STD

Front 9

young sexual active female presents w frequency, urgency and disuria. She c/o copious d/c. Her gram stain is negative, blood cultures in chocolate and mcconkey agars are also negative.
- what would be the most likely organism
- best diagnostic modality

Back 9

chlamydia infection causing urethritis.

its DOES NOT grow on choco or mconkey.

Hint 9

GIEMSA analysis of D/C could be (+) stains protein and nucleic a.

serology or molecular tech useful

Front 10

clinical symptoms of UTI

Back 10

dysuria, frequency, urgency in 50-60%

Hint 10

lower flank pain: kidney/bladder
inguinal pain: bladder, urethra, prostate.

Front 11

details requested in UA for diagnosis of UTI

Back 11

UA
PMNs and bacteria
gram stain or acid fast stain
culture on blood/choco/mconkey agars
- gram stain isolates

Hint 11

UA non specifics, look for:
blood
elevated protein levels

Front 12

if a organism grows on mcconkey agar, what type of microorganism is it?
what further studies are needed for differentiation?

Back 12

most likey enteric gram negative

Hint 12

lactose fermentation

Front 13

most common lactose fermenters
- appearance

Back 13

e.coli
klebsiella
enterobacter

Hint 13

colonies appear pink purple
TSI agar/mcconkey

Front 14

what would be a significat value of CFU in urine culture, when would this rule not apply

Back 14

10 to the 4- 10 to 5 cfu per ml.

Hint 14

acute dysuria (sp type)
indwelling catheter

Front 15

the most common enteric bacteria
gram ? microorganism that is methyl red +,
indole +,
lactose fermenter

Back 15

gram +

Hint 15

e-coli,

Front 16

this property is specific to Proteus and Klebsiella

Back 16

UREASE +

Front 17

gram +
catalase -
utilizes bile and esculin

Back 17

enterococci

Front 18

Non enteric a/w cystitis and is more prevalent in europe

Back 18

staph. saprophiticus

Front 19

non enteric bacteria
coagulase -
novobiocin resistant

Back 19

staph. saprophiticus

Front 20

considered one of the most motile microorganisms, sulfur producer

Back 20

proteus

Front 21

micoorganism that is a/w kidney stone formation,
urease and sulfur producer,
non lactose fermenter
highly motile

Back 21

proteus

Front 22

male pt p/w dysuria, copious d/c w organisms found inside and outside neutrophils.

Back 22

gram (-) diplococcus:
Neisseria gonorrhae

Front 23

female p/w mild dysuria, h/o multiple sexual partners.
gram stain of vaginal exudate shows a pink gram (-) kidney bead shaped cocci

Back 23

gonorrhea

Front 24

a female pt presented with urethritis an mild d/c, no other symptoms. condition resolved without treatment. What risk does this patient carry?

Back 24

silent carrier that continues to spread the infection

Front 25

extragenital syndromes of gonorrhea

Back 25

proctitis
pharyngitis

Front 26

female patient presents w arthritis , skin pustules, mainly on the left knee. she recalls an episode of PID in the past

Back 26

gonorrhea extragenital disease, GC now is present in the blood,also presents w PID alone

Front 27

a physician is concerned in the management of this microorganism culture. he request specifically chocolate agar, rapid transport to the lab. The organism is incubated under fastidious microaerophilic conditions. whats the most likely organism affecting the patient from which the sample was taken

Back 27

N. gonorrhea
grows in moist areas of thebody

Front 28

this organism does NOT like air
is oxidase +
ferments ONLY glucose: this confirms the diagnosis

Back 28

N. gonorrhea

Front 29

this factor determine the virulence of N. gonorrhea, it prevents the death of the PMN

Back 29

the Pili
- strains w pili are more infectious
- they help the gonococcus attach to the mucosa
- possible role in vaccine development

Front 30

a patient was diagnosed w gonorrhea after treatment he asks if hes protected against contracting the condition again?

Back 30

yes he is at risk because even though there is antibody produced it is not effective in producing immunity.

Front 31

male pt w dysuria, copious purulent d/c developes 2-6 days after sexual contact, gram stain shows a gram (-) diplococcus inside PMN

Back 31

n. gonorrhea

Front 32

it is the most common reported STD and the most common cause of non-gonococcal urethritis

Back 32

chlamydia trachomatis

Front 33

a female high school senior presents w light/clear d/c she mentioned it looked like milk, and in small amount. She is sexually active from a high socio-economical status. the progression of this disease can lead to infertility , PID

Back 33

chlamydiosis

Front 34

young female high school students admits to being sexually active, p/w discharge that is clear. gram stain is negative, no bacteria is seen in specimen, but found some inclusion bodies and when iodine was added it stained glycogen.
DFA shows cytoplasmic inclusions.
this organism is visualized inside host cells after GIEMSA staining.

Back 34

C.trachomatis a obligate intracellular pathogen so called "energy parasites" they need the ATP of the host cell to survive.

Front 35

what are the 4 stages of the life cycle of C.trachomatis

Back 35

1-elementary body: extracell inactive
2- reticulate body element (IC growing)
3- inclusion body (growing RB that mature inside host cell)
4- Intracell life: 48-72h.
--it acts almost like a virus
