![126 3.—“ X ” DISEASE: ENQUIRY re SEQUELS FOLLOWING AUSTRALIAN EPIDEMICS OF 1917-1918. (28/21947). (E. L. Morgan.) In view of the known occurrence of post-encephalitic sequelae such as Parkinsonianism, Professor J. B. Cleland, of Adelaide University, requested that inquiries be made as to whether any of those persons who suffered from “ X-disease ” during 1917-1918 and recovered exhibited any after effects. A letter asking for information was forwarded to the Government Medical Officers in towns where cases had occurred. The replies indicated a confusion between “ X-disease,” Encephalitis Lethargica, and Infantile Paralysis, and except in one or two instances it is doubtful if the information supplied referred to individuals who had recovered from “ X-disease.” It would appear from the replies that the medical men who had been circularised knew of no undoubted case which exhibited after-effects, though this would not necessarily mean that all who suffered from the disease have remained well ever since. In the event of there being such cases it is difficult to see how authentic information concerning them could be obtained, especially when the confusion above-mentioned exists. The replies were forwarded to Professor Cleland for further study. 4,—SYDNEY MILK SUPPLY : (1) EXAMINATION OF SUBURBAN MILK FOR (a) TUBERCLE BACILLI; (b) BACTERIAL CONTENT. (E. L. Morgan.) (a) The systematic examination for tubercle bacilli in milk from dairies which supply the metro politan area of Sydney has been continued, and 142 samples were collected and examined from 97 dairies (2,466 milking cows) between 15th May and 31st December, 1928. No tubercle bacilli were found either by the microscopical examination of centrifuged sediment or by guinea-pig inoculation. Towards the latter end of the year one of the guinea-pigs inoculated with a sample of milk from dairy Cl/S developed a lesion of the spleen which in some respects resembled tuberculosis. The possibility of this lesion being due to Brucella abortus is under investigation. (b) Bacterial Content.—In 83 samples the bacterial counts were under 100,000 colonies per cc., and in 42 the counts ranged between 100,000 and 600,000 per cc. In the seventeen samples which gave an unduly high count the procedure followed in connection with the dairies was similar to that described in the report for 1927. j 14 graphs, 4 photos, 2 diagrams.] Sydney: Alfred James Kent, I.S.O., Government Printer—1930.](https://iiif.wellcomecollection.org/image/b31485194_0162.jp2/full/800%2C/0/default.jpg)
