Примери за sera

• All 31 cases provided acute sera, 19 provided convalescent sera and 14 had viral throat/nose swabs taken.

• Sera from individuals known to be affected by immunosuppressive conditions or by an acute infection or to have recently undergone blood transfusion were excluded.

• Dilutions of the sera were allowed to react with the coating antigen.

• Sera were tested at 1 in 200 dilution on antigen coated plates.

• A week after the last dose of antigen, jirds were bled from the retro-orbital plexus and immune sera were isolated.

• The rabbits were bled before the immunizations, and the sera obtained were used for control studies.

• The sources of sera used have been described previously [8].

• The wells were incubated for 2 h at room temperature with diluted human sera.

• Blots were incubated overnight with the various test sera.

• The sole exclusion criterion was sera collected from individuals with known immune deficiencies.

• Sera has been systematically collected from mice and rats either harbouring a schistosome infection, or vaccinated with the isolated membrane preparation.

• Saving tests by pooling sera - how great are the benefits ?

• All sera for which the result was equivocal were retested.

• In total, 4943 (48n9 %) sera were from males and 5175 (51n1 %) from females.

• The duration of this maternally derived immunity was determined experimentally from sera of unvaccinated children.
