were enumerated on mannitol salt agar (MSA, LuQiao, Beijing, China) after incubation at 37[degrees]C for 48 h.
1) Bacteria involved are coagulase-negative staphylococci, corynebacteria, micrococci
, diphtheroids and propionibacteria.
They reported six positive cultures from the body and label of 15 fentanyl ampoules (Bacillus pycoides, micrococci
and coagulase negative staphylococci), although there were no positive cultures from the head or neck of the ampoules.
No internal labeling of nonpathogenic staphylococci and micrococci
was observed, and it was suggested that transferrin-mediated transport processes were involved in cell-specific uptake.
Assignment to the genus Kytococcus was suggested by the arginine dihydrolase activity and resistance to oxacillin, 2 characteristics that are not shared by other micrococci
Besides anthrax research, he focused on several other projects, including wound infections and micrococci
in septicemic animals (later identified as streptococci and staphylococci).
