The characteristics described - Gram-positive cocci in pairs, nonhemolytic, and bile salt tolerant - are all consistent with Enterococcus. Staphylococcus and Streptococcus can also cause bacteremia, but they are usually hemolytic and bile salt sensitive. Mycoplasma and Listeria are not cocci and would not be expected to cause bacteremia in this scenario. Therefore, Enterococcus is the best choice.
