   Test)

ALA (RAPID PORPHYRIN TEST) 

Principle 

This test is used for rapidly detecting porphyrin as a means of speciating Haemophilus species.
Enzymes which convert ALA (delta - aminolevulinic acid) to porp hyrins in the biosynthesis of
hemin (X factor) are produced by Haemophilus parainfluenzae but not by  H. influenzae.  The
production of porphyrins is detected by examination with an ultra-violet (UV) light.

Reagents 

BBL  TAXO  Differentiati on Disks ALA.  (Store refrigerated in the da rk.  Allow 10-15 minutes
for the container to reach room temperature before opening).  
Sterile distilled water

Other Materials

Petri dish
Inoculating loop
Gauze
Long-wave UV lamp
Forceps

Procedure

1.  Place one ALA disk  for each organism to be tested on  the inside of a  Petri dish using
forceps.
2.  Moisten each disk with one drop of sterile water.
3.  Rub a loopful of the test organism onto the  moistened disk holding it in place with sterile
forceps.
4. Saturate gauze with  water, squeeze out any excess and place it in the petri dish as far away
from the disks as possible.
5.  Incubate at 35
o
C.
6.  Examine at hourly intervals for 6 hours by re moving the top of the petri dish and exposing
the disks to UV light  in a darkened room.   NB:  Wear UV safety goggles when using the
UV light.

Interpretation 

A.  Positive:  Orange-red fluorescence

B.  Negative:  No fluorescence observed

Precautions 

1.  Use for differentiating  Haemophilus spp. only.

2.  Best results are obtained wh en a heavy inoculum is used.

3.  ALA is light sensitive.  Disks must be protected from light.

Quality Control

Test the following positive and negative co ntrols each time an  unknown is tested:

 Positive: H. parainfluenza  (ATCC 7901)
 Negative: H. influenzae        (ATCC 35056)

Special-Potency Disks

ANAEROBE IDENTIFICATION US ING SPECIAL-POTENCY DISKS 

Principle 

Special potency antimicrobial disks of vancomycin (5  µg), kanamycin (1,000  µg) and colistin
(10  µg) are used as an aid in determining the Gram reaction of anaerobes as well as in
preliminary categorization of some anaerobic genera and species (Table 1).  In general, gram
positive organisms are resistant to colistin and  susceptible to vancomycin, while most gram
negative organisms are resistant to vancomycin.  Th is difference is especially useful with some
Clostridia that consistently stain gram negative.

Materials

A.   Reagents

1.   Special potency antibiotic disks: 

 Vancomycin  5 µg
 Kanamycin  1,000 µg
 Colistin  10 µg

Store a small supply of disks (one carton each) in a tight container with desiccants
at 4
0
C.

2.   Brucella or other anaerobic blood agar plate.

B.   Supplies

1.   Single disk dispenser or forceps
2.   Ruler (divided into millimeters)

Procedure

1.   Allow the container with disks to reach room temperature before opening it.
2.   Subculture the isolate on a BAP.  To ensure an even, heavy lawn  of growth, streak the
first quadrant back and forth se veral times.  Streak the other  quadrants to yield isolated
colonies.
3.   Place the three antibiotic disks on the first quadrant will apart fr om each other.  
4.   If you have several organisms to test, first streak all the plates and  then add the disks to
them at the same time.
5.   Incubate the plate(s) anaer obically for 48-72 hours at 35-37
0
C.
6.   Examine for zones of inhibition of growth around the disks.

Interpretation

A.  Susceptible:  Zone of inhibition of ≥  10 mm
B.  Resistant:  Zone of inhibition of < 10 mm

Quality Control 

A.   Test special potency antibiotic disks by lot when initially received and weekly thereafter.

B.   Test  Bacteroides fragilis  (ATCC 25285),  Clostridium perfringens (ATCC 13124), and
Fusobacterium necrophorum  (ATCC 25286) as described below under Procedure.  The
results should show the following:

1.   B. fragilis: resistant to all  three antibiotics
2.   F. necrophorum: resistant to vancomycin; susceptible to colistin and kanamycin 
3.   C. perfringens : susceptible to vancomycin and kanamycin and resistant to colistin

C.   Record the results on a QC log.
