Urine specimen inoculation tests can be used to: check for the presence of Gram-negative or positive bacteria in urine in the clinic, which can be reported.
The fecal specimen taken directly affects the accuracy of the results, usually using naturally excreted feces, specimen collection precautions are as follows:
The VP assay can be applied to (1) identify Enterobacter aerogenes and Escherichia coli, and (2) characterize other bacterial groups, including actinomycetes.
Most of Candida albicans need oxygen 25-30 ℃ to grow well, can also be in 37 ℃ above the growth. Colonies are cream-colored, pie-shaped and smooth. In the cor
