Abstract

The possibility of studying and developing new techniques to detect the infections is human fluids is an important and open matter. The developed technique is based on the very precise control of the variation of propagation velocity and attenuation of ultrasonic signals coming across crystal bottles with a culture of a sample of the liquid in function of time at controlled temperature and pressure. The technique is able to detect the positive indication of bacteria existence several hours before the commercial systems for all the bacteria and fungi studied
