Evaluation of streptococcal XXXX caused by group B @entity5967 in adults in Japan between 2009 and 2013.

@entity1 @entity281 @entity137 @entity5967
UNASSIGNED: Infection with @entity5967 has long been recognized in @entity1 . In recent years, @entity5967 is an important cause of morbidity and mortality among adults and among those with underlying medical condition. Several cases of @entity281 and more fulminant disease similar to streptococcal @entity137 have recently been reported. We report here that 19 @entity5967 strains were isolated from streptococcal @entity137 cases involving adult @entity1 in Japan between 2009 and 2013. The average age of the @entity1 was 66.3 years. At least one underlying disease was present in 47.4% (9/19) of the @entity1 . The most prevalent serotype among these strains was Ib. 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 @entity137 isolates differed between isolates obtained from vaginal swabs of @entity1 and @entity1 with invasive @entity281 .
