Subject: Multodisks

The "Multodisk" was discontinued a number of years ago.It represented a paper disc method of testing bacterial sensitivity to antibiotics and sulphonamides.Each Multodisk was a sterile fillter paper disc having 6 or 8 projecting arms .The tips of each were impregnated by known levels of antibacterial agent and were available in a number of standard combinations for clinical applications.
The disc was placed on a plate of sensitivity test agar medium seeded with the test organism.After incubation the zone of inhibition produced would represent the degree of sensitivity to the agent;and a combination of results should indicate the appropriate chemotherapy to combat the pathogen identified.
The Multodisk has been replaced by single discs in cartridges of 50 discs which can be delivered using a 6 or 8 place dispenser onto the plates.
I trust this clrifies your e-mailed enquiry.
