The key biochemical reactions by which the family
Key Biochemical reactions for
Enterobacteriaceae can be identified include
Enterobacteriaceae:
fermentation of carbohydrates, reduction of
nitrates to nitrites and the absence of cytochrome
oxidase activity.
ANA See 2 quiz #27
Results in a false positive reaction; is the result of
Prozone effect:
antibody excess and dilution of antibody can help
prevent its occurrence
Purpose of a bi-chromatic Minimize the effect of interference

wavelengths is:
Susceptible to bacitracin ("A") and resistant to
Key characteristics of furazolidone; gram positive cocci in tetras, bacteria
Micrococcus:
cells of micrococcus luteus are larger than those of
the staphylococci and can arrange in tetras
95 mL/min
One method of calculating a glomerular filtration rate is
using creatinine and urine volume to determine
What is the glomerular
creatinine clearance. The equation is as follows:
filtration rate for a patient
with a serum creatinine of
Creatinine Clearance = (urine creatinine X urine flow rate) /
2 mg/dL, if the urine plasma
creatinine was 124 mg/dL creatinine; where urine flow rate = volume in mL /24 hours x
and the urine volume was h/60 min)
2.2 L/24 hrs?
, In this case = creatinine clearance = 124 X (2200/24 x
hour/60) / 2 = 94.7 or 95 ml/min
Estrogen and progesterone Breast cancer

serum, followed by a positive result as the specimen
is diluted.

Resistance to furazolidone is one of the key
characteristics by which members of the genus
Distinguishing characteristics Micrococcus (resistant) can be separated from
of Micrococcus luteus: members of the genus Staphylococcus
(susceptible). Micrococcus
species also are susceptible to novobiocin and to
bacitracin, although the zone of inhibition to the "A"
disk is often small (as shown in this
photograph).
The sickling phenomenon Reducing agents actually induce the sickling
observed in erythrocytes phenomenon in RBCs when they contain hemoglobin
