3 bacteria implicated in contamination of blood, 1 thats not3 parasites transmitted by blood
Yersinia, Citrobacter, Pseudomonas-these are the books answer-possibly staph/strepE.Coli has notPlasmodium, Trypanosoma(cruzi), Babesia

Potentiators:-which one decreases incubation-which one books says increases sensitivity-shortens incubation, increases speed/sensitivity, decreases zeta, phosphate buffered saline/glycine-increases sensitivity for IAT, longer incubation-increases sensitivity, removes water increasing concentration of ab, enhances warm auto-eliminate rxns, can enhance coldwarm auto-reduce disulfide bonds, eliminates Kell
Potentiators:-decreasse incubation LISS-increase sensitvity albuminLISS low ionic strenght sln-shortens incubation, increases speed/sensitivity, decreases zeta, phosphate buffered saline/glycineBSA/albumin-increases sensitivity for IAT, longer incubationPEG-increases sensitivity, removes water increasing concentration of ab, enhances warm autoProteolitic enyzmes-eliminate rxns, can enhance coldwarm autoDTT, dithiothreitol-reduce disulfide bonds, eliminates Kell
