Viral transport media is important for the study of infectious diseases. The medium must be suitable for the culture of various viral samples and maintain the viability of the samples. There are different types of viral transport media and each one has its own characteristics. Read on to learn about these factors. These media should have the following characteristics: they must be long-lasting, contain protein and antibiotics, and be free from fungal and microbial contamination. They should prevent the sample from drying up and should be pH-balanced. They must also be compatible with column membrane or magnetic bead extraction.

A commercial viral transport media is available in screw-cap plastic tubes and contains antibiotics and buffered proteins. These substances are used to suppress the growth of contaminating bacteria and fungi. The two samples should be collected separately, as bacteria and fungi have different requirements. The most suitable viral transport media contain a pH-balanced buffer solution with a source of protein and antimicrobial agents, and a preservative such as sucrose. Without the right media, viral specimens will degrade quickly and there is a greater risk of false negative results.

Virological transport media are used to safely transfer the samples from the patient to the laboratory. They are often composed of buffer solutions and antimicrobials.
