Protein residues on medical equipment are profiled by bacteries which results with an increase in the number of bacteria that causes a drawback for a proper sterilization. In addition, these kind of residues on these medical equipment are the sign of life forms that causes the risk for infection. To prevent these kind of infections, identification and cleaning of protein residues are obligatory.</description></oembed>
