UNMC Scientists Train on New Device That Could Significantly <\/p>\n

Decrease Time to Identify Infectious Disease Bacteria <\/p>\n\n\n\n
<\/td>\n<\/tr>\n
Peter Iwen, Ph.D., assistant professor, pathology and microbiology <\/p>\n

and associate director of the Nebraska Public Health Laboratory at UNMC, <\/p>\n

demonstrates how<\/p>\n

the Roche Molecular Biochemical LightCycler works. A lab sample is placed <\/p>\n

in<\/p>\n

the black cylinder which works with a computer program that runs and analyzes<\/p>\n

test results. <\/td>\n<\/tr>\n<\/table>\n

If you work in a laboratory and saw the movie "Jurassic Park," you <\/p>\n

probably noticed the process Hollywood scientists used to extract and duplicate <\/p>\n

dinosaur DNA from mosquitoes preserved in amber. The process, called polymerase <\/p>\n

chain reaction, or PCR for short, allows scientists to substantially increase <\/p>\n

the amount of DNA in a laboratory sample in order to perform tests on it. <\/p>\n

Typically, the PCR process takes about three hours with days sometimes required <\/p>\n

to analyze the product. But biotechnology – the application of biology <\/p>\n

and engineering – is speeding that up to 35 to 40 minutes. <\/p>\n

The Nebraska Public Health Laboratory (NPHL) at the University of Nebraska <\/p>\n

Medical Center has received a new piece of equipment that ultimately could allow <\/p>\n

pathologists and microbiologists to get results of their laboratory tests in <\/p>\n

a fraction of the  time it now takes. <\/p>\n

Laboratory personnel have received training and are experimenting with<\/p>\n

the Roche Molecular Biochemical LightCycler. Peter Iwen, Ph.D., assistant<\/p>\n

professor, pathology and microbiology and associate director of the NPHL,<\/p>\n

said the LightCycler could drastically cut the time it takes to identify<\/p>\n

infectious disease agents, including those that may be used for biological<\/p>\n

terrorism.<\/p>\n

If you can cut the time down from detection to identification, then you could <\/p>\n

start quarantine and treatment sooner and thats always a good thing, Dr. Iwen <\/p>\n

said. <\/p>\n

The laboratory is one of several dozen sites in the United States that have <\/p>\n

the new equipment. It was acquired through a grant from the U.S. Centers for <\/p>\n

Disease Control and Prevention through the Nebraska Health and Human Services <\/p>\n

System. <\/p>\n

Dr. Iwen and other scientists around the country are currently developing protocols <\/p>\n

for the LightCycler through the National Laboratory Response Network, in which <\/p>\n

the NPHL participates. These protocols will ultimately be used to detect a variety <\/p>\n

of pathogens causing infectious diseases, including bacteria such as the anthrax <\/p>\n

and plague bacilli.  <\/p>\n

Though the technology is currently only used as a screening tool, backed<\/p>\n

up by the classic way of growing bacteria on culture medium in a Petri<\/p>\n

dish, the technology may ultimately make this process obsolete.<\/p>\n

People dont want to wait four or more days to get results, Dr. Iwen said. <\/p>\n

This technology could cut two or even four days off of what is now a three- <\/p>\n

to five-day process. <\/p>\n

The technology allows lab technologists to watch the test go through<\/p>\n

each cycle on the computer screen as it happens.<\/p>\n

The biggest advantage of the technology is its ability to rapidly do<\/p>\n

PCR and ultimately identify the product all within one amplification, he<\/p>\n

said.<\/p>\n

We will continue to do the cultures in testing for suspected anthrax<\/p>\n

bacillus exposure until we develop protocols and get more comfortable with<\/p>\n

the technology, Dr. Iwen said.<\/p>\n

The LightCycler costs about $60,000 and was purchased through federal<\/p>\n

grant money, he said. Plans to purchase this instrument were in the works<\/p>\n

before the mailed anthrax spore attacks.<\/p>\n

Weve tried to get this equipment for the last several months but lack of <\/p>\n

funding was an issue, Dr. Iwen said. This is an excellent investment for the <\/p>\n

future. We need to be on the cutting edge in this area of science.  This <\/p>\n

is up there on the top rung of current technology.<\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"
