Such a te st would be useful not only as a diagnostic tool but would also be a valuable adjunct in following the course of the disease. Early attempts at serologic identification of tuber culosis were far from specific. Bacillary agglutination (Koch, 19ul) as well as complement fixation (Bordet and Gengou, 1903; Much, 1912; Harris and Lanford, 1913; Bang and Anderson, 1913; Negre and Boquet, 1920) gave cross re actions not only with other species of Mycobacterium but also with syphilitic sera (Besredka and Jupiile, 1913) and with sarcoidosis (Carnes and Raff el, 19l|9). The place of complement fixation in the serologic investigation of tuber culosis is excellently reviewed by Wadsworth, Maltaner and Maltaner (1925). Agglutinin adsorption and subsequent bacil lary agglutination is useful for the differentiation of species within the genus but too unwieldy for routine work (Wilson, 1925; Furth, 1926). The same is true of quantitative -2- complement fixation (Cooke, 1919)* The precipitin test was trie d in early investigations and the resu lts are, of necessity, dependent on the antigen employed. F iltra te antigens such as those of Besredka and Jupille (1913) and Petroff (1917» 1916) and saline extrac tions such as those of M iller and Zinsser (1916) showed some early promise of specificity but did not survive extensive clinical tests. Seibert (1936) improved the specificity of precipitation but her high protein antigen gave a low de gree of sensitiv ity . It is generally accepted that the pres ence of precipitins is not correlated with the state of the disease (Rich, I 9I4I4) * Results of sim ilar studies with pre cipitation of Old Tuberculin fractions seemed to correlate with the degree of skin sen sitiv ity rather than with the stage or severity of the infection (Meuther and Macdonald, 19M-1 i McCarter and Watson, I 9I4.2 ). More recent work by Chou- croun (19)4.7, 1914.7a, 19l|9 ) has shown that the presence of an anti-carbohydrate precipitin in the serum is related to in fection and recovery but the very mechanics of precipitation preclude any great degree of sen sitiv ity . Workers in other field s, realizing the great difference in sensitiv ity between agglutination and precipitation, have made attempts to enhance the sen sitiv ity by increasing the volume of a precipitate by adsorbing antigens to bacterial cells (Jones, 1927 > 1926; Roberts and Jones, 19)41; Meuther and Macdonald, 19ipS) and collodion p articles (Cannon and -3- Marshall, 19ij.O; Lowell, 191+3) • The method of collodion par tic le agglutination was adapted to the investigation of tu berculous serum by Weir (191+1) but again the specificity of the reaction depends on the specificity of the antigen chosen for coating of the particle. The use of red blood cells as antigen carriers by Bur net (19lj.6) in the detection of antibodies to mumps virus, and by Keogh, North and Warburton (19i|8) in the adsorption of bacterial polysaccharides, led to the idea of antigen se lectiv ity of ’’schleppers". This was followed by the demon stration by Middlebrook and Dubos (19^8) that sheep red cells would adsorb antigen from extracts of tubercle bacixli and were subsequently agglutinable by specific antiserum. Numer ous clin ical investigators have designed tests to evaluate the Middlebrook-Dubos hemagglutination reaction and have ob tained widely differing results, and offered different in terpretations of these resu lts. All are agreed, however, that there is more than one antigen and more than one a n ti body involved. Following the use by us (DeWitt, 1951J De- Witt _et _al, 193>1) of this test in the attempted diagnosis of tuberculosis in c attle , i t was concluded that (1) neither hemagglutination nor hemolysis are sufficiently specific for such diagnostic work but (2) that an investigation of the antigens and antibodies involved would be worthwhile. Ac cordingly, the following experiments were designed with the purpose of distinguishing and evaluating those antibodies -k- which could be experimentally produced without the presence of the disease its e lf and, thus, with the hope of removing specific interfering factors. REVIEW OF LITERATURE The agglutinability of red cells following contact with bacteria or bacterial products was f i r s t recorded by Thomsen (1927) and attributed to enzymic a ctiv ity by Friedenreich in 1928. The observation that bacteria can a lter erythrocytes and render them panagglutinabie by most normal sera has been repeatedly confirmed (Landsteiner, 191+5) • Burnet, McCrea and Stone (19A4.6) attributed a sim ilar effect by Newcastle Disease virus to a lecithinase and showed that virus tre a t ment prevented la te r bacterial adsorption to the same red cells. Such virus modified red cells were not specific In their agglutinability (Burnet and Anderson, 19lj-6) but la te r Burnet (I9I4.6 ), in order to explain the immunizing capacity of mumps virus treated cells, fe lt i t necessary to assume that either the virus p article or a breakdown product of the virus was attached to the red c e ll. Burnet and Ander son (I9I4.7 ) while working with the "T" antigen of guinea pig and human red cells showed that Vibrio cholerae extracts were active in producing this change in the erythrocyte, and that the enzyme involved could be eluted from the cell, leaving a previously undetectable antigen on the cell. The f i r s t definite demonstration of bacterial antigen adsorption by red blood cells was that of Keogh, North and Warburton (19i|-8) who used an antigenic fraction which was composed predominantly of polysaccharides. This phenomenon -6- was extended to work with trypanosomiasis by Muniz (1950), to glanders by Boyden (195b), to tularemia by Alexander, Wright and Baldwin (195b) and Wright and Feinberg (1952) and to pertussis by pillemer (195b). Such hemagglutination was used for investigation of the antigenic relationships of Mycobacteria by Fisher (1951)* The cross reaction of tuberculin treated erythrocytes and serum from patients with Hansen’s disease was deemed diagnostically significant by Levine (1951), Middlebrook and Dubos (19ij-h) f i r s t showed agglutina tion of tuberculin treated red cells in the presence of tu berculous antiserum. Their primary antigen was a phenol and acetone insoluble, methanol soluble extract of Mycobacterium tuberculosis var. hominis (H37Rv) with the activity seeming ly residing in the polysaccharide fraction. As l i t t l e as 0.ip gamma of antigen per ml could be detected by hemaggluti nation inhibition, and i t was shown that the antigen was also present in at least one sample of Old Tuberculin. No cross reactions were noted with antisera against piplococcus pneumoniae (I, III, XIV), K lebsiella pneumoniae (B. C) or serum from sy p h ilitics. The specificity of the reaction was reported to be good with only occasional reactions of low titre occurring with serum from patients not actively tuber- culous. This in itia l report was soon followed by modifications and clinical application. Gernez-Rieux and Tacquet (191+9) -7- used human group "0" cells as antigen carriers and reported positive hemagglutination in 88 per cent of patients shown to have active tuberculosis. Sohier (195U) noted a tenden cy for well advanced cases of pulmonary tuberculosis to give negative reactions. This phenomenon is commonly encountered in other chronic diseases. He reported few false posi tives except in the case of BCG vaccinated individuals and later (Sohier, Trimberger and Juiliard, 195b) modified the test to the use of a purified tuberculin (I.P.lj.8) and human group "0" cells. Rothbard, Dooneief and Hite (195^), inde pendently of Sohier, reported the use of tuberculin for cell sensitization, and lis te d positive results in 5 per cent of normal humans tested, 18 per cent in other diseases, 6 per cent in skin test negative individuals and 89 per cent in proven cases of tuberculosis. Scott and Smith (195u ) pub lished a simple modification of the reaction which was stan dardized to the use of a concentrated tuberculin (Lederle, IpC Int. Std.J, which fa c ilita te d wide-spread comparison of clinical results. While they at f ir s t presented results showing hemagglutination titre s greater than 1:2 in 78 per cent of tuberculous patients, and 35 per cent of BCG vacci nated individuals and completely negative results in normal patients, they la te r reported (Smith and Scott, 195^) less dramatic resu lts. With a larger sampling the percentage of positive tests in tuberculous individuals changed l it t le , as did the resu lts in healthy and sick persons with negative
