Case ReportsTravel-related leptospirosis in Japan: a report on a series of five imported cases diagnosed at the National Center for Global Health and Medicine.
Leptospirosis is one of the most common travel-related infections. We report 5 cases of travel-related leptospirosis who presented at our clinic between January 2008 and December 2013. Patients were included in the study if they presented with a clinical profile that was compatible with the disease within 21 days of their return from traveling, which were laboratory-diagnosed as leptospirosis by blood culture, rise in antibody titers in paired sera using the microscopic agglutination test (MAT), and/or DNA detection using flaB-nested PCR. ⋯ Patients were treated with penicillin G, minocycline, or doxycycline. One case was cured without antibiotics. A diagnosis of leptospirosis should be considered for febrile travelers who return from Southeast Asian countries to Japan after being exposed to freshwater while traveling.

Evaluation of streptococcal toxic shock-like syndrome caused by group B streptococcus in adults in Japan between 2009 and 2013.
Infection with Streptococcus agalactiae has long been recognized in infants. In recent years, S. agalactiae is an important cause of morbidity and mortality among adults and among those with underlying medical condition. Several cases of GBS infection and more fulminant disease similar to streptococcal toxic shock syndrome have recently been reported. ⋯ All serotype Ib strains belonged to clonal complex 10 and were ciprofloxacin resistant. In contrast, all strains were susceptible to penicillin G, ampicillin, cefazolin, cefotaxime, imipenem, panipenem, and linezolid. The characteristic type distributions of streptococcal toxic shock-like syndrome isolates differed between isolates obtained from vaginal swabs of women and infants with invasive infections.

Case ReportsCapnocytophaga canimorsus bacteremia presenting with acute cholecystitis after a dog bite.
Capnocytophaga canimorsus is part of normal gingival flora of dogs and cats. The organism can cause septicemia, meningitis, and endocarditis in humans after contact with dogs or cats. In spite of the frequency of gastrointestinal symptoms in C. canimorsus infection patients, specific gastrointestinal disease or clinical images have not been reported. ⋯ This case revealed that C. canimorsus bacteremia can be presented with acute cholecystitis, suggesting that C. canimorsus could cause cholecystitis. And this cholecystitis can be treated with antibiotics without operation. Physicians seeing patients with acute cholecysitis should ask questions regarding animal contact.
