HUMAN GLANDERS: REPORT OF SIX CASES

Abstract
Six cases of glanders occurring in laboratory workers are described in detail. Five patients contracted focal pulmonary lesions, and the 6th patient showed evidence of acute splenitis and/or perisplenitis. Malleomyces mallei, the causative organism of glanders, was not isolated in any case. The specific diagnosis was based on a significant rise in serum ag-glutinin titer for M. mallei in all 6 cases; on positive complement-fixation for M. mallei in 4 cases; and on positive mallein skin tests in 5 cases. All of these observations were adequately controlled with extensive serologic studies on normal subjects, who failed consistently to show significant agglutination or complement-fixation titers, and who showed no reaction to commercial mallein given intradermally. Because of its demonstrated efficacy in curing hamsters infected experimentally with M. mallei, sulfadiazine in full dosage over a 10- to 20-day period was given to all 6 patients in this series at different stages of disease. Two patients showed a definite clinical response to chemotherapy; the remaining 4 patients were in various stages of recovery when treatment was initiated.
