ABSTRACT:
Microporous anionic exchange and non-ionic adsorbent resins which are capable of adsorbing an antibiotic and which have been coated with a non-ionic detergent are disclosed. When contacted with bacterially infected body-fluid specimens, the disclosed resins remove antibiotics from the specimen while exhibiting diminished bacterial adsorption. A combination of a disclosed detergent-coated non-functional adsorbent resin with a cationic resin removes other bacterial inhibitors, as well as antibiotics, from bacterially infected body fluid specimens while permitting the bacteria to remain in the specimens. By removing bacterial inhibitors while sparing the bacteria, the disclosed resins make possible rapid isolation and identification of an infecting organism.
