EMLab P&K's E. coli and Enterococci detection services; Integrated DNA Technologies' PrimeTime qPCR assays

Millipore was warned by the agency in September about an e-mail promotion for certain products for H1N1 influenza detection.

Millipore claims that its test, which incorporates transcription-mediated amplification technology developed by Gen-Probe offshoot Roka Bioscience, provides a few advantages over PCR-based Mycoplasma testing.

Investigators will compare results from the FilmArray PCR test to results from conventional platforms, like viral culture and antibody tests, as well as to results from other molecular diagnostic technologies.

An international research team sequenced and compared almost 100 serotype M3 group A Streptococcus genomes from bugs causing three epidemics in Ontario over more than 15 years.

In a paper appearing online today in Science, researchers reported that they have come up with a high-throughput sequencing-based approach for teasing apart relationships between methicillin-resistant Staphylococcus aureus isolates from around the world and within a single health care facility.

The British Columbia Centre for Disease Control said today that it plans to sequence the genomes of hundreds of influenza viruses in an effort to understand the pandemic 2009 H1N1 virus' entry and evolution in the province — including how it may be affected by the Vancouver Olympics.

A group of German researchers used an RNA interference screen to find human host factors required for the replication of several influenza A viruses, including non-pandemic and pandemic H1N1 viruses and an H5N1 bird flu virus.

A University of York team used transcriptome sequencing and pedigree studies to create a genetic map for Artemisia annua, a plant that contains a compound used to help treat some forms of malaria.

The clearance covers a respiratory viral test for both RSV and hMPV.

The UK-based company also signed on Inverness Medical Canada to distribute its products in the country.

An analyst with William Blair & Co. upgraded Cepheid shares to "outperform" from "market perform."

Quidel said that Diagnostic Hybrids' fluorescent in vitro diagnostic assays would complement Quidel's point-of-care diagnostics for infectious disease and reproductive health.

The FDA cleared Cepheid's Xpert vanA test for the antimicrobial resistance gene most commonly associated with vancomycin-resistant enterococci.

The test runs on Cepheid's RT-PCR-based GeneXpert System. The FDA-cleared Xpert vanA test will be available for shipment to customers this month.

Cepheid became the latest firm to receive an EUA for its H1N1 flu assay, but said it is the first to receive the designation for CLIA moderate complexity labs.

One study identified a variant of the 2009 H1N1 influenza virus that Gen-Probe's ProFlu+ test failed to flag as positive for influenza A, while a second study found an "unexpected" amount of mutability in the matrix gene of the virus that stymied PCR-based subtype testing via melting temperature analysis.

AdvanDx received 510(k) clearance for 90-minute versions of its Escherichia coli/Pseudomonas aeruginosa and EK/P. aeruginosa diagnostic tests.

The assay was developed through Affymetrix's MyGeneChip Custom Array Program. It is the latest in a series of molecular diagnostic products to get an FDA EUA.

The funds will support development of a high-throughput platform for screening infectious disease treatments.
