Begin the process of identifying unknown bacteria by observing their physical characteristics, such as cell wall, shape and linkages use standard laboratory procedures, like cell staining, culturing and dna sequencing to further narrow down your identification. The reasons for accurate identification of pathogenic bacteria are: interpretation of antibiotic susceptibility testing often rests on identification two different bacteria may give the same values on this test, but the definitions of susceptible and resistant are different in different species. Basic bacterial identification by microscopy there are too many microorganisms to remember therefore they need to be separated into groups with similar features microbiologists use a number of terms to describe the different appearances of bacteria gram-positive or gram-negative, coccus or bacillus etc.
So bacterial identification is a necessary part of disease diagnosis and cure without the identification of causative bacteria, it is tough to provide effective treatment with available antibiotics. The growth requirement and the appearance of colonies on media to the naked eye are further criteria to assist the identification of bacteria a culture is a growth of bacterium on artificial nutrient medium or culture medium prepared in the laboratory. 1 observe and record the morphology of colony and pigment production in nutrient agar plate or tube to identify a bacteria by its colonial morphology only, may not be enough.
In conclusion, the suggested molecular method appears to be a promising tool for the early identification and definition of pathogenic bacteria in blood samples, which may not only allow the medical staff to make a precise diagnosis, but also to administer quick and appropriate treatment to the hospitalized patient.
