Why is it difficult or possible identify microorganism in mixed culture?
It can be difficult to identify microorganisms in a mixed culture because of the complexity of the environment and the presence of multiple organisms. Many microorganisms are difficult to identify and differentiate from one another especially in a complex microbial community. In addition the same species of microorganism may exist in different varieties which can further complicate the process of identification. Furthermore environmental factors such as temperature pH nutrient availability and the presence of other organisms can affect the growth and composition of the microbial community making it difficult to accurately identify individual species.In order to identify microorganisms in a mixed culture several techniques can be used: Growth on specific media Morphological characterization Biochemical tests Molecular characterization Genetic fingerprintingThese techniques can be used to accurately identify microorganisms in a mixed culture although the process can be time consuming and expensive. As such it is important to consider the costs and benefits of identifying microorganisms in a mixed culture before attempting to do so.

What is the medical term for the sample of the drainage that was grown in the lab to identify the microorganism and determine the best antibiotic?
Culture and sensitivity, sometimes abbreviated C&S, is the process of growing a sample to ID the organism (culture) and determine which antibiotics are active against that pathogen (sensitivity).
When is a blood culture done?

Culture
Is a culture media used to support growth of microorganism?
Agar
