CDC Evaluation of Brain Heart Infusion Agar Plates Containing 6
[mu]g of Vancomycin Per ml To Detect Vancomycin-Resistant Strains of
Staphylococcus aureus
AGENCY: Centers for Disease Control and Prevention (CDC), Department of
Health and Human Services (DHHS).
[[Page 42191]]
ACTION: Notice of an evaluation study and request for public comment.
-----------------------------------------------------------------------
SUMMARY: This notice announces a study to evaluate the effectiveness of
Brain Heart Infusion Agar plates containing 6 [mu]g of vancomycin (BHI-
V) per ml to detect Vancomycin-resistant Staphylococcus aureus.
The CDC would like manufacturers of BHI-V to submit a total of 120
agar plates, 40 plates each of three different lots of BHI-V agar, for
testing. The protocol is available on request.
The purpose of this study is to validate the use of BHI-V agar
plates, which are currently approved by the Food and Drug
Administration in the United States for detecting vancomycin-resistant
Enterococcus species, for detecting vancomycin-resistant Staphylococcus
aureus.
DATES: Comments on the CDC Evaluation of Brain Heart Infusion Agar
plates containing 6 [mu]g of vancomycin per ml to detect Vancomycin-
resistant strains of Staphylococcus aureus must be received in writing
on or before September 13, 2004.
FOR FURTHER INFORMATION CONTACT: Dr. Roberta Carey at (404) 639-3032,
e-mail: RCarey@cdc.gov, prior to 4 p.m. on Friday, September 7, 2004.
ADDRESSES: Comments should be submitted to Dr. Roberta Carey, Centers
for Disease Control and Prevention, National Center for Infectious
Diseases, Division of Healthcare Quality Promotion (C-16), 1600 Clifton
Rd., NE., Atlanta, GA 30333, or via e-mail: RCarey@cdc.gov.
SUPPLEMENTARY INFORMATION: Strains of Staphylococcus aureus that are
resistant to the antimicrobial agent vancomycin pose both clinical and
public health concerns. Such strains are difficult to treat and have
the potential to spread broadly in healthcare settings causing
outbreaks of infection. The first fully vancomycin-resistant isolate of
S. aureus (VRSA) was isolated from a patient in Michigan in June 2002.
A second isolate of VRSA was recovered from a patient in Pennsylvania
in September 2002. Unlike the first isolate, resistance in the second
isolate was difficult to detect in clinical laboratories using
automated antimicrobial susceptibility testing methods. A third VRSA
was recovered recently in New York (2004). This isolate also was not
detected as fully resistant to vancomycin on initial testing with
automated laboratory methods. To enhance the capability to detect VRSA,
the CDC proposes that clinical microbiology laboratories inoculate a
BHI-V agar plate with colonies of S. aureus, particularly methicillin-
resistant strains of S. aureus, in conjunction with routine methods of
antimicrobial susceptibility testing. Since the BHI-V plate is
currently approved by FDA only for use with Enterococcus species, the
reliability of these commercial media for S. aureus needs to be
established. The CDC proposes to evaluate, free of charge, all
commercially prepared BHI-V currently approved for distribution in the
United States. The CDC requests that 120 plates, 40 plates each of 3
different lots of BHI-V agar, be provided to CDC by the manufacturers
of these products. The data generated by CDC will be shared with FDA.
Those manufacturers who wish to label their product for use with S.
aureus can request review of these data by contacting Sally Selepak at
301-594-2096 in the Division of Microbiology, FDA. The study is to be
initiated on September 13, 2004.
