Marsupial Species

A collection of sera from 81 species of Australasian marsupials and 65 antisera to them, prepared in rabbits, chickens, or various species of marsupials, was examined to devise a scheme to identify the blood of marsupials imbibed by blood-sucking insects. The precipitin test was of limited value but established that the blood was marsupial. With the haemagglutination inhibition test, however, it was possible to identify the family, subfamily, genus, and species. Thus a procedure could be devised to identify the donors' blood based principally on serological methods supplemented by data on the geographical distribution of the various marsupial species.

Haemagglutination Inhibition Test

The importance of the haemagglutination-inhibition test does not need to be stressed. It is a fact that the inhibition titre of a single serum has no constant value, but may vary in repeated estimations. This may be due to the use of different virus or erythrocyte suspensions or to differences in environmental circumstances, such as temperature. Duplicate tests carried out at the same time and with the same materials yield identical results. This makes it necessary to compare a serum obtained during convalescence from the same case. The ratio between the two titres shows whether an influenza infection has taken place or not. Although it is commonly accepted that a titre rising by two twofold dilutions (a fourfold rise) is significant, some workers will accept even a twofold rise (Sartwill & Long, 1948; Rasmussen, Stoles & Smadel, 1948). Such observations have been made on pairs of sera taken from the same indicidual with not more than a 5-week interval between them.

Haemagglutination Inhibition Test

ABSTRACT A modified haemagglutination inhibition test (Luteonosticon) was used to estimate human pituitary LH in urines from 66 women and 2 men. The results were compared with those obtained by a radioimmunosorbent method on the same urine samples. The correlation between the results of the two methods was highly significant (P < 0.001).
