Isis Pharmaceuticals' Ibis T5000 Universal Biosensor System Highlighted at ICAAC Friday September 29, 7:00 am ET
CARLSBAD, Calif., Sept. 29 /PRNewswire-FirstCall/ -- Isis Pharmaceuticals, Inc. (Nasdaq: ISIS - News) announced today that scientists from its Ibis Biosciences(TM) (Ibis) division and collaborators presented the results of five diverse studies emphasizing the importance and breadth of applications of the Ibis biosensor technology and the Ibis T5000(TM) Biosensor System in identifying and characterizing infectious organisms. The studies were presented at the 46th Annual International Conference on Antimicrobial Agents and Chemotherapy (ICAAC) held this week in San Francisco, CA, which hosted more than 10,000 attendees comprising physicians, clinicians and researchers working in the fields of clinical diagnostics, drug discovery and microbiology.
The Ibis T5000 is a breakthrough universal biosensor system that supports the rapid and efficient identification, characterization and quantification of a broad range of bacteria, viruses and fungi in virtually any sample without prior knowledge of what organisms may be present. The system does not require time- and labor-intensive steps such as sequencing or culture, and it can be used to obtain high-resolution genotypes of organisms in a rapid, high-throughput manner. The Ibis T5000 Biosensor System has been extensively validated for a number of assays and is being commercialized by Ibis and its partner, Bruker Daltonics, a subsidiary of Bruker BioSciences Corporation.
Commenting on the ICAAC presentations, Dr. David Ecker, Chief Scientific Officer of Ibis Biosciences and Vice President of Isis, said, "We are very pleased with the breadth of data presentations included at this meeting. The studies highlighted exemplify the substantial contribution the Ibis T5000 Biosensor System can make in the identification and characterization of infectious organisms in broad applications, from epidemiologic surveillance to identifying and preventing hospital-acquired infections, and eventually to disease diagnostics. As we begin to commercialize our Ibis biosensor technology, the opportunity to display its capabilities, with the strong support of our collaborators, to the broader infectious disease community is invaluable."
A summary of the presentations follows:
An MLST Schema and Rapid MLST Analysis Strategy for Molecular Genotyping of Acinetobacter baumannii for Infection Control
Authors: C. Massire, J. A. Ecker, T. A. Hall, R. Ranken, T. D. Pennella, C. Agasino Ivy, L. B. Blyn, S. A. Hofstadler, V. Harpin, A. Schink, D. J. Ecker, R. Sampath, M. W. Eshoo; Ibis Biosciences
Acinetobacter infections are frequent complications of wound infections and have been particularly problematic in military personnel injured in Iraq. The Ibis T5000 Biosensor System rapidly identified and characterized with regard to virulence and drug resistance factors, Acinetobacter organisms in more than 267 samples from infected soldiers. The method required less than 4 hours to provide genotypic identification of the Acinetobacter strain types that caused the infections.
Such information was used to determine that the source of the infection was hospital-based, disproving the initial hypothesis that the infections were soil-based, and allowed appropriate steps to be taken to reduce the incidence of future infections.

Rapid Determination of Ciprofloxacin Resistance in Clinical Isolates of Acinetobacter spp. Using Polymerase Chain Reaction Electrospray Ionization Mass Spectrometry (PCR/ESI-MS)
Authors: K. M. Hujer(1), A. M. Hujer(1), T. D. Pennella(2), C. Massire(2), M. W. Eshoo(2), D. J. Ecker(2), R. A. Bonomo(1); (1)VA Medical Center, Cleveland, OH; (2)Ibis Biosciences
In the treatment of serious bacterial infections, the rapid initiation of appropriate antimicrobial therapy is life saving. We showed that the Ibis T5000 Biosensor System can be used to determine the sequence variability of the housekeeping genes, gyrA and parC, in Acinetobacter spp. and rapidly characterize a quinolone-resistant phenotype. Seventy-five Acinetobacter spp. isolates from the Walter Reed Army Medical Center in Washington, DC were analyzed. More than 90% of the isolates in this polyclonal collection are resistant to ciprofloxacin. Single point mutations encoding amino acid in gyrA topoisomerases highly correlated with phenotypic ciprofloxacin resistance in Acinetobacter spp. The Ibis T5000 analysis showed that base compositions of these regions unambiguously distinguished ciprofloxacin-susceptible from ciprofloxacin-resistant isolates. There was agreement between data provided by the Ibis T5000, restriction enzyme digestion and MICs, confirming the reliability of the Ibis T5000 analysis. This novel and rapid approach to the characterization of infectious organisms can provide essential information for resistance determinant identification and therapeutic decision making.
According to Robert A. Bonomo, M.D., Section Chief, Infectious Diseases Louis Stokes Cleveland Veterans Affairs Medical Center, "Conventional methods would have required months of work, but in this project, we were able to get the results from the Ibis T5000 system within a few days ... Our vision is that this technology will be used to simultaneously identify pathogens and determine resistance phenotypes so that appropriate therapy can be rapidly instituted."

TIGER PCR Mass-Spectrometry and Rep-PCR Characterization of Community-Acquired Oxacillin Resistant Staphylococcus aureus Isolates
Authors: D. M. Wolk(1), D. Shepley(2), D. Sloane(2), R. Sampath(3), V. Harpin(3), L. Blyn(3), D. Ecker(3), V. Wysocki(4), S. Hofstadler(3); (1)SAVAHCS/Univ. of Arizona, Tucson, AZ; (2)SAVAHCS, Tucson, AZ; (3)Ibis Biosciences; (4)Univ. of Arizona, Tucson, AZ
Drug resistant Staphylococcus aureus is an important cause of hospital-acquired infections (HAI), a significant and growing public health issue. These infections are often life threatening and poorly treated because the infective organisms are so virulent and drug resistant. Oxacillin-resistant Staphylococcus aureus is a strain that is prevalent in both hospitals and in the community at large.
The Ibis T5000 Biosensor System was used to characterize 87 isolates of Oxacillin-resistant Staphylococcus aureus and the results were compared to results from traditional culture methods and the Cepheid IDI-MRSA assay. The Ibis T5000 rapidly produced extremely accurate and sensitive results, and supported high-throughput analysis, making it an ideal approach to the identification and genotyping of both community- and hospital-acquired drug-resistant Staphylococcus aureus.

Rapid Detection and Molecular Characterization of Influenza Virus Using RT-PCR/ESI-MS Technology
Authors: V. Harpin, N. Fan, T. Pennella, R. Melton, B. Libby, H. Lavene, C. Massire, D. Walcott, F. Li, A. Schink, T. Hall, C. Ivy, M. Eshoo, R. Ranken, J. Drader, M. Pear, L. Blyn, S. Hofstadler, D. Ecker, R. Sampath; Ibis Biosciences
Because influenza viruses mutate constantly, there are many flu strains. The virulence of and immunological responses to each strain of virus vary substantially. Epidemics occur annually and these epidemics are frequently caused by different strains. Furthermore, influenza viruses that infect species other than humans occasionally acquire the ability to infect humans. Thus a rapid, efficient system such as the Ibis T5000 that can identify, quantify and genotype influenza viruses is urgently needed.
In this study presented by Ibis scientists and collaborators, the Ibis T5000 Biosensor System was able to very rapidly and reliably identify and genotype all influenza viruses including avian strains. It was able to 'map' epidemics and to determine the strains involved in several annual influenza epidemics.

Broad-Range Detection and Identification of Alphaviruses in Biological Backgrounds Using RT-PCR and High Resolution Mass Spectrometry
Authors: M. W. Eshoo(1), C. Whitehouse(2), L. B. Blyn(1), T. A. Hall(1), J. Ecker(1), T. D. Pennella(1), C. Massire(1), A. Desai(3), R. Sampath(1), D. J. Ecker(1), S. A. Hofstadler(1); (1)Ibis Biosciences; (2)U.S. Army Med. Res. Inst. of Infectious Diseases, Fort Detrick, MD; (3)SAIC, San Diego, CA
Alphaviruses are a diverse group of RNA viruses that are principally mosquito-borne. They cause a number of diseases such as encephalitis and are of concern as potential biological weapons.
The Ibis T5000 Biosensor System was used to genotypically characterize 31 diverse strains of alpha viruses. This study demonstrates the utility of the Ibis T5000 in rapidly and efficiently determining the causes of diverse viral diseases and defining the causes of viral epidemics as well as potentially bioengineered organisms.

I wonder if it will detect species previously not known to cause diseases, as in other species of borrelia, bartonella, and babesia. If they don't know about these yet, how can they be plugged into this dandy machine? And will it pick up cyst forms? Surely someone will ask these questions at the conference.

Thanks for posting this. I live in Carlsbad, and was bitten by the tick in Carlsbad, so how ironic that a Carlsbad company is working on this technology.
Perhaps I can interview him for an upcoming Lyme Times article. Hopefully there will be videos or transcripts of the LDA conference so I can see what he has to say, then maybe try to follow up here locally and report back to everyone.

OK, here is another question to ask these people at the conference: if borrelia are tissue trophic, will blood tests using this device be any more accurate than the ones that already fail to find it so often?
Better hold off on the stock purchase, charlie, until we get more answers.
