1356503 Immunological test LEO AB 5 May 1972 [6 May 1971] 21138/72 Heading G1B Erythrocytes bearing phages derived from bacteria are used in the detection of phage antibodies in serum and are produced by a method which comprises contacting the erythrocytes with an aqueous aliphatic aldehyde solution, contacting the resulting aldehyde - treated erythrocytes with bacteriophages at a temperature above 45‹ C and then contacting the phage-bearing erythrocytes with an aqueous aliphatic aldehyde solution. Such erythrocytes form a diagnostic substance; when mixed with serum from a living body, agglutination indicates infection of the body by bacteria whose phages are similar to those borne by the erythrocytes. The erythrocytes may be treated with tannic acid after the first aldehyde treatment and before contacting with bacteria. The contacting with bacteria is preferably done in the presence of a sugar or a protein. The treated cells may be lyophilized. In Examples the bacteria are staphylococci. |
