Optical system technology enables rapid detection of sepsis pathogens
Optical system technology enables rapid detection of sepsis pathogens September 28, 2015 Source: Bio Valley -- In the case of treatment of blood poisoning, doctors immediately take broad-spectrum antibiotics. The problem is that in many cases, some bacteria are resistant to drugs. Analysis of bacterial antibiotic resistance is a time consuming process that results too late for many patients. Now, scientists at the Fraunhofer Institute for Applied Research Promotion in Germany have developed a new technology that can give results in just nine hours. The patient's blood poisoning, also known as sepsis, requires medical staff to quickly give diagnosis and treatment. Some doctors will start using broad-spectrum antibiotics right away, but antibiotics don't always have the desired effect. For example, if the bacteria are resistant to the drug used, the antibiotic will fail. It is usually 60 to 100 hours to identify pathogens in the laboratory and investigate their potential antibiotic resistance. The patient can't wait, and in most cases leukemia will kill the patient in about 48 hours. In Germany, for example, 60,000 people die each year from blood poisoning. If this pathogen resistance analysis requires less time, it will save the lives of many patients. Once the doctor knows whether the pathogen is resistant to certain antibiotics, they can treat the patient with targeted antibiotics to reliably kill the bacteria. German scientists have made rapid detection a reality. Their test method can get results in just nine hours. What makes the detection speed ten times faster? Researchers have developed a miniaturized system with a special optical design. The first step in the test is to label the pathogens of sepsis and expose them to a laser environment. This allows researchers to assess the number of pathogens present in the blood. In the next phase of detection, the pathogens are separated from the blood and enter a separate culture zone. In these different culture zones, each zone contains a medium of specific antibiotics. The next step in the optical system records the growth of bacteria in different culture zones, observing and accurately documenting how the bacteria multiply. Then there is the most critical step: the algorithm analyzes the pictures of the collected bacteria and the growth curve of the bacteria in the culture area. This means that researchers can see the growth of bacteria in different antibiotic environments within a few hours to find out which antibiotic resistance. Essentially, the core of this detection technique is that the growth of bacteria in different antibiotic environments can be accurately observed and recorded by the optical system. Using software to analyze the extent of bacterial growth, the system can provide data on the number of bacteria and the proportion of dead bacteria in different auxin media. Ultimately this system can give a conclusion as to which antibiotics are resistant to the pathogen. This automated, rapid detection method will undoubtedly lead to a great increase in detection efficiency, and won more time for leukemia patients to overcome the death.
