A previously healthy 26-year-old man presented with fever, headache, skin rash, and thrombocytopenia. Cultures of blood and cerebrospinal fluid yielded a fastidious gram-negative bacillus, identified as DF-2. A unique feature of this case was the presence of a false-positive latex agglutination result for cryptococcal antigen in the cerebrospinal fluid in the absence of pleocytosis. Additional laboratory studies, which included indirect immunofluorescence and sodium dodecyl sulfate-polyacrylamide gel electrophoresis, however, failed to reveal common antigenic surface components between these organisms.
一名既往健康的26岁男性出现发热、头痛、皮疹和血小板减少。血液和脑脊液培养分离出一种苛求革兰阴性杆菌，鉴定为DF-2。该病例的一个独特特征是脑脊液中隐球菌抗原乳胶凝集试验结果呈假阳性，而无细胞增多。然而，包括间接免疫荧光和十二烷基硫酸钠-聚丙烯酰胺凝胶电泳在内的其他实验室研究未能揭示这些微生物之间常见的表面抗原成分。
