ASM Journal Articles of Interest

Antibiotic Resistant Bacteria Proliferate in Agricultural Soils
Published in the March Antimicrobial Agents and Chemotherapy, a new study finds reservoirs of resistance in agricultural soils. These contained more diverse populations of drug resistant bacteria, with greater levels of resistance, than composted and forest soils. Vegetable garden soil alone harbored multi-drug resistant bacteria, and also had the highest level of resistance to three major antibiotic classes. http://www.asm.org/images/Communications/tips/2012/0312soil.pdf

New Genomic Data Could Aid Rapid Detection of Pathogenic Enteroccus
Enterococci bacteria, and, in particular, vancomycin resistant enterococci, have emerged as a leading cause of multidrug-resistant hospital-acquired infection.  Researchers from Harvard Medical School and The Broad Institute report new genomic sequencing data that can help aid in the advance detection of pathogenic enterococci.  They report their findings in the current issue of mBio®. http://mbio.asm.org/content/3/1/e00318-11

Decontamination, DNA Extraction, and Amplification Procedures on the Molecular Diagnosis of Mycobacterium ulcerans Disease (Buruli Ulcer)
Authors compared two DNA extraction methods on 74 surgical tissue specimens from patients with clinically suspected Buruli ulcer to determine the best for the molecular diagnosis method for Mycobacterium ulcerans disease. http://jcm.asm.org/content/50/4/1195.full.pdf+html

Evaluation of PNA FISH Probes for Identification of Candida Species from Blood Cultures
The Yeast Traffic Light system of identification distinguishes between pathogenic species of Candida using Fluorescence in situ hybridization using peptide nucleic acid probes (PNA FISH).  The study tested 216 positive blood cultures for the presence of C. albicans/Candida parapsilosis, C. glabrata/Candida krusei and Candida tropicalis.   http://jcm.asm.org/content/50/4/1446.full

PCR Identification of Bacteria in Blood Culture Does Not Fit the Daily Workflow of a Routine Microbiology Laboratory
Investigators evaluated the GenoType blood culture assay for the identification of bacteria in 233 positive blood cultures and assessed its suitability in the workflow of a routine microbiology laboratory http://jcm.asm.org/content/50/3/1031.full.pdf+html

ABMM Certification
The American Board of Medical Microbiology (ABMM) certifies the expertise of doctoral-level microbiologists seeking to direct public health or clinical microbiology laboratories. It is recognized by federal and state governmental agencies as a significant component toward meeting licensure requirements to direct laboratories engaged in the microbiological diagnosis of human disease. It is recognized under the Clinical Laboratory Improvement Amendments of 1988 final rule and in all 12 states that require licensure.

ABMM certification is achieved by passing an online multiple-choice exam that is offered daily in the month of June at testing centers worldwide. Visit http://www.microbiologycert.org/ to learn more and apply online. Deadline: April 1, 2012

FEDERAL AGENCY UPDATES

FDA Proposes Lower Risk Classification for Certain Tuberculosis Tests
The Food and Drug Administration (FDA) issued a proposed rule that would encourage the development of a type of test used to detect cases of tuberculosis (TB). This rule would lower the current risk classification for nucleic acid-based tests allowing manufacturers to utilize the faster, more streamlined clearance pathway for medical devices.  To read more about this development, please click the link http://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/ucm296308.htm

FDA Approves the First Quadrivalent Vaccine to Prevent Seasonal Influenza
FluMist Quadrivalent, a vaccine to prevent seasonal influenza in people ages 2 years through 49 years, was approved February 29 by the FDA. This is the first influenza vaccine to contain four strains of the influenza virus: two influenza A strains and two influenza B strains.  For more information, see http://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/ucm294057.htm

FDA Approves the First Helicobacter pylori Breath Test for Children
The first breath test for use in children ages 3 to 17 years to detect Helicobacter pylori infections, which are responsible for chronic stomach inflammation (gastritis) and ulcers, was approved by the U.S. Food and Drug Administration (FDA) on Feb. 22, 2012. The FDA first cleared the BreathTek UBT H. pylori test for adults in 1996.  To see the report in its entirety, go to http://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/ucm293278.htm

NIH-Supported Scientists Investigate a Newly Emerging Staph Strain

MMWR Articles of Interest

Tuberculosis Outbreak Associated with a Homeless Shelter: Kane County, Illinois, 2007–2011
In January 2010, public health officials recognized an outbreak of TB after three overnight guests at a homeless shelter in Illinois received diagnoses of disease caused by Mycobacterium tuberculosis isolates with matching genotype patterns. As of September 2011, a total of 28 outbreak-associated cases involving shelter guests, dating back to 2007, had been recognized, indicating ongoing M. tuberculosis transmission.  

Reducing Bloodstream Infections in an Outpatient Hemodialysis Center: New Jersey, 2008–2011
In 2009, to decrease BSI incidence in a New Jersey outpatient hemodialysis center, a package of interventions was instituted, beginning with participation in a national collaborative BSI prevention program and augmented by a social and behavioral change process to enlist staff members in infection prevention. 

Vital Signs: Preventing Clostridium difficile Infections
In this investigation, three data sources were used to identify health-care exposures for Clostridium difficile Infections (CDIs), determine the proportion of CDIs occurring outside hospital settings, and assess whether prevention programs can effectively reduce CDIs. CDC's Emerging Infections Program conducted active, population-based surveillance for CDIs from eight diverse geographic areas in 2010.

Outbreak of Shiga Toxin–Producing Escherichia coli O111 Infections Associated with a Correctional Facility Dairy: Colorado, 2010
On April 21 2010, stool specimens from the initial three inmates reported as ill tested positive for Shiga toxin at a reference clinical laboratory and subsequently were identified as STEC O111 at the state public health laboratory. CDPHE and correctional facility health staff members conducted surveillance for other persons with recent illness through cell checks and interviews with all food-service workers, resulting in identification of five additional laboratory-confirmed STEC O111 cases. A confirmed case was defined as STEC O111 isolated from an inmate's stool specimen.  

Outbreak of Cryptosporidiosis Associated with a Firefighting Response:  Indiana and Michigan, June 2011
On June 20, 2011, the Indiana Department of Homeland Security notified the Indiana State Department of Health (ISDH) of an Indiana fire station that reported gastrointestinal illness among a substantial percentage of their workers, causing missed workdays and one hospitalization as a result of cryptosporidiosis.
