Abstract
Abstract A microbiological culture collection and transport device maintains viable organisms for periods of time longer than possible with existing sampling devices. It also allows recovery of detectable antigen at levels not achievable with conventional swabs. The new device has a sterile swabbing tip made with a non-toxic polyurethane foam having open cells at its exposed surface. It does not require a transport medium and can be used dry. The device may further include a sample inoculator to distribute organisms collected onto a solid or semi solid medium. Methods for collecting and transporting microbiological specimens and for recovering detectable antigen are also described.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
152 words
A viable microorganism collecting and transporting device without transport media, comprising: a longitudinally extending sleeve container member comprising an open end, a closed end, and an inside and outside wall; a cap comprising an exterior and interior face being removably attachable to said open end and outside wall of said container; a shaft comprising a first and second end, wherein said first end is connected to said interior face of said cap; a swabbing tip connected to said second end of said shaft wherein said swab is made with a polyurethane foam which is specifically non-toxic to live microorganisms; said outside wall of said container member and said cap are longitudinally slidable relative to each other and form a slidable seal; a seal inoculator connected to said exterior end of said cap; and an inoculator cover removably attachable to said cap, to cover and protect the inoculator from contamination prior to use.
