mixed infection

infection with more than one agent at the same time.

mixed lymphocyte reaction

a test for histocompatibility between donor and recipient; lymphocytes from both are mixed in vitro and the responses quantitated by measuring the uptake of tritium-labeled thymidine (³H-TdR). In the usual assay one of the two populations which will serve as the target is blocked from undergoing blastogenesis by the drug mitomycin. The degree of incompatibility is reflected in the amount of cell division as measured by the uptake of ³H-TdR, incompatibility increasing the uptake of ³H-TdR.

mixed tumor

canine mammary tumors are often mixtures of epithelial, myoepithelial or connective tissues. Mixed tumors also occur in the dog in the thyroid, sweat and salivary glands.
