Enterobacter cloacae - Wikipedia ; The name E. hormaechei was formerly called enteric group 75, which contained 11 strains that were sent to the CDC for identification between 1973 and 1984. Twelve additional strains were received from 1985 to 1987, three of which were blood isolates. E. hormaechei was first described on the basis of 23 isolates sent to the CDC for ... Serratia marcescens internalization and replication in ... ; BACKGROUND: Serratia marcescens, a frequent agent of catheterization-associated bacteriuria, strongly adheres to human bladder epithelial cells in culture. The epithelium normally provides a barrier between lumal organisms and the interstitium; the tight adhesion of bacteria to the epithelial cells can lead to internalization and subsequent lysis. 放課後のスター テキスト
