1. GOVERNMENT BACTERIOLOGICAL INSTITUTE.
INTRODUCTORY.
(1) Administrative.-No changes are to be recorded under this head. No officers were on long leave, nor were there any additions to the existing staff.
(2) Buildings and equipment.—(a) During the latter part of the year the open verandah on both sides of the office was enclosed and thus incorporated into the building proper so as to add to the office space, which was far too small for the requirements of the Institute.
(b) No addition to the permanent equipment was made during the year.
(3) Library. The following book was added to the library: -
The Pathology of Internal Diseases, Wm. Boyd, 1935.
(4) Research.-(a) Typhoid. An investigation into the presence of agglutinins against typhoid organisms in cases showing no clinical signs of the disease was continued. The sera for test were obtained from bloods sent from the Venereal Diseases Clinic for Kahn test, and should represent a good cross-section of the hospital population of Hong Kong. No European cases were included, the great majority being Chinese, with a proportion of Indians. The number tested totalled 229 cases; of these 224 showed no agglutination in the lowest dilution used, (1 in 50). Of the five cases showing some agglutination, one showed only a doubtful reaction in the lowest dilution against the O antigen and no agglutination at all against the H antigen. Another case showed doubtful O agglutination 1 in 50, with H agglutination in both 1 in 50 and 1 in 100. A third case showed O agglutination to 1 in 50 with H agglutination to 1 in 100. The two remaining cases both showed no O agglutination at all with H agglutination to 1 in 50 only. Actually only cases two and three could have caused any difficulty in diagnosis as far as typhoid was concerned; such a diagnosis could not have been considered from the serological result in the other three. A further investigation will be carried out in 1938 on the Widal reaction as observed on cases showing an elevated temperature due to other known infection. The idea in this case is to determine whether such cases show any non-specific agglutination in the dilutions used in our test, or whether residual agglutinins are stimulated by their infection to a significant extent.
