Persistent cyclic herpes simplex virus infection in vitro. IV. Changes in the severity of the infections in the presence of antibody.

abstract：:Clostridium difficile is a gram-positive, spore-forming enteric anaerobe which can infect humans and a wide variety of animal species. Recently, the incidence and severity of human C. difficile infection has markedly increased. In this study, we evaluated the genomic content of 73 C. difficile strains isolated from hu...
