Sera were obtained from 233 veterinary professionals in the Tokyo and Chiba areas. As negative control group, sera from 155 healthy individuals (all medical(More)
BACKGROUND There are growing numbers of reports concerning the clinical and pathological features of Helicobacter cinaedi (H. cinaedi) bacteremia; however, few reports have discussed the features of this condition in healthy individuals. PATIENTS AND METHODS A retrospective observational study was conducted at a Japanese tertiary care hospital to assess(More)
To examine whether hepatitis C virus (HCV) infection still occurs in haemodialysis units even after a decrease in the number of blood transfusions and in those contaminated with HCV, we tested anti-HCV antibodies and HCV RNA in 142 patients from Japanese haemodialysis units, and examined the serial prevalence of anti-HCV antibodies in 86 patients from 1992(More)
We report herein on a case of Plasmodium malariae malaria with more than a 4-month incubation period. A 35-year-old Japanese man who first presented to our clinic with fever and history of travel to Papua New Guinea was suspected of having Plasmodium vivax malaria based on peripheral smear results. We admitted him and initiated treatment with mefloquine.(More)
