calculate the percent of white blood cells or isolate the pathogen from an infected host and use it to infect a healthy animal or isolate bacterial or viral proteins by electrophoresis?

Isolate the organism from blood or other specimen. If the organism is a virus, detect antibodies to that virus in blood. The white cell count is usually increased with a bacterial infection and normal in a viral infection. In an overwhelming infection like septicemia , it may be low. Therefore, it is not a definite test. It is only supportive.

calculating the percentage of white blood cells doesn't tell u anything bout the pathogen. doesn't even tell u the stage of the infection cuz there are infections that cause leucopenia. the best thing is to get an antibiogram, you can also use western blotting, northern blotting or PCR.

according to microbiology you must first isolate the infectious pathogen in the ill host then you must infect a healthy host and observe it to see if it causes the same symptoms
