Abstract: An integrated device for diagnostic analyses used to verify the presence of bacteria in at least a biological sample mixed with a eugonic culture broth, in order to identify the type of bacteria, and to test a series of antibiotics, identifying those effective to determine the antibiotic therapy. The device comprises first examination means to verify the presence of bacteria so as to define corresponding positive biological samples and identify the type of bacteria present in the positive biological samples to define said group of antibiotics, and second examination means to verify the sensitive or resistant response of each positive biological sample to a series of antibiotics of the group of antibiotics defined by the first examination means.
