艱難梭菌艱難梭菌VPI10463 ATCC43255

Clostridioides difficile strain VPI 10463 was isolated from an abdominal wound. This strain is toxigenic (toxinotype 0) and was confirmed by PCR to contain the tcdA and tcdB genes. The whole-genome sequenced bacterial strain has applications in enteric disease research and infectious disease research.

Handling procedure
Open vial according to enclosed instructions.  Under anaerobic conditions, withdraw 0.5 mL of #2107 broth from a single test tube (5 to 6 mL) and rehydrate the entire vial contents.
Aseptically transfer this aliquot back into the broth. Additional tubes may be inoculated with 0.1 mL each from the suspension. 0.2 mL may also be inoculated onto a slant. Streak several blood plates to check for colonial morphology and purity.
Incubate tubes under an anaerobic atmosphere at 37°C.  Incubate one agar plate anaerobically for colony formation, and one aerobically for aerobic contamination check.
Within 24-48 hours, growth should be evident by turbidity in the broth and by colonies on the anaerobic agar surfaces.  No growth should occur on agar plates incubated aerobically.




ANAEROBIC CONDITIONS:

Anaerobic conditions for transfer may be obtained by either of the following:

Use of an anaerobic gas chamber, or
Placement of test tubes under a gassing cannula system connected to anaerobic gas.


Anaerobic conditions for incubation may be obtained by any of the following:

Loose screw caps on test tubes in anaerobic chamber,
Loose screw caps on test tubes in an activated anaerobic gas pack jar, or
Use of sterile butyl rubber stoppers on test tubes so that an anaerobic gas headspace is retained.
Handling notes
Anaerobe Systems Brucella Blood Agar plates (AS-111 or AS-141) can be used to analyze colony morphology and purity.
This item can also grow in #5608 broth.
