Methods for detecting and treating polymicrobial infections, wherein a mixed population of microbes (e.g., bacteria) are present in a patient sample and the microbes are not first isolated from the sample. For example, the present invention describes specific polymicrobial infections and methods of treating said infections, wherein a particular antibiotic or a group of antibiotics are selected based on the composition of the polymicrobial infections.

Methods for identifying and providing therapeutic solutions for treating polymicrobial infections, such as but not limited to urinary tract infections. The methods herein feature detection and identification of organisms of the polymicrobial infection, phenotypic pooled sensitivity tests for determining the susceptibility or resistance of the polymicrobial infection in the sample to an antibiotic or other therapeutic agent, and identification of resistance genes, e.g., genetic markers that may indicate resistance to a particular treatment. Together, the data can be applied against databases of antibiotic/therapeutic susceptibility or resistance for particular known polymicrobial infections in order to provide one or more therapeutic solutions for the polymicrobial infection.

Apparatus and methods for creating deposits of uniformly spaced or uniformly overlapping droplets of selected chemicals where each droplet has an a priori known amount of the selected chemical or chemicals is taught (including biological and microbial materials). In some embodiments the deposits may be used as samples of different but known concentrations that may be used to calibrate spectroscopic inspection instruments to enable such instruments to not only provide identification in situ of unknown materials but also to provide calibrated and traceable surface concentrations of such materials. In some embodiments, such calibrated instruments may be used in enhanced processes for validating the cleanliness of manufacturing surfaces such as surfaces of equipment used in the preparation of pharmaceuticals, food, or semiconductor devices. Such instruments may be used to ensure adequate purity, or non-contamination, of surfaces of products themselves or packaging materials or of locations where such products will be used. Such calibrated instruments may also be useful in detecting cleanliness of non-manufacturing surfaces where contamination may be of concern, whether they be public or private spaces such as laboratories, restaurants, airports, satellites or other spacecraft. In some embodiments, such instruments may range from deep UV instruments to far infrared instruments or beyond.

A method and a device for performing are qualitative and quantitative assay of biofilm-forming bacteria of at least one bacterial species contained in an aquatic system by use of a biochemical reaction of the bacteria with at least one substance which initiates a bacterium-specific metabolic reaction, as well as a colorimetric reagent which can be influenced by the metabolic reaction involving measurement of the spectrometric properties thereof forming the basis of the assay.

The invention provides a technology for promptly determining bacterial identification or an antimicrobial susceptibility testing. In the invention, first, a state where the bacteria are divided is monitored by performing microscopic observation with respect to the shape or the number of bacteria in each of wells of a culture plate for bacterial identification culture or the antimicrobial susceptibility testing. In addition, the shape, the number or the area of the bacteria are interpreted from the image obtained by the microscopic observation whether or not the bacteria proliferate at a stage from an induction phase to a logarithmic phase, and the time-dependent changes thereof are made into a graph. From the graph, it is determined whether or not the bacteria proliferate for each measurement, the determination results are displayed on the screen, and accordingly, the result of the antimicrobial susceptibility is provided every time when the measurement is performed.
