Escherichia coli strains harbouring the Yersinia pseudotuberculosis inv gene are able to enter cultured mammalial cells. We show here that this property is not shared by all enteric bacteria, since Shigella flexneri 2a cured of its virulence-associat

Because the mechanism whereby Shigella dysenteriae I enterotoxin induces intestinal secretion is unclear, the effect of this toxin on adenylate cyclase activity in rabbit ileal mucosa was studied under various in vitro and in vivo conditions. Activat

Shigellosis remains a major public health problem in developing countries. In these nations, the disease affects young children for the most part. The infecting organism causes illness by invading the colonic mucosa. It is closely related to nonpatho

One of the chromosomal segments associated with the virulence of Shigella flexneri and transferred to Escherichia coli K-12 by conjugation has been shown to code for the production of aerobactin and for the synthesis of an iron-regulated 76,000-dalto

A temperate phage, designated Sf6, has been isolated from Shigella flexneri 3a. Characterization of Sf6 revealed that it possesses the capacity for converting the S. flexneri 3,4 group antigen complex to group factor 6. Serological studies and chemic

Normal human peripheral blood lymphocytes, monocytes, and granulocytes decreased the viability of Shigella flexneri in vitro in cooperation with heat-inactivated rabbit hyperimmune anti-shigella antisera. Purified K and T lymphocyte populations used

The incorporation of [14C]leucine into protein was studied in two mammalian cell lines which had been infected with strains of Shigella dysenteriae 1, Shigella flexneri 2a, or Salmonella typhimurium W118. These cell lines differed in susceptibility t

To investigate the characteristics of intestinal ion and fluid secretion induced by the adherent, effacing enteropathogenic Escherichia coli strain RDEC-1, we infected weanling rabbits with 10(7)-10(8) RDEC-1 organisms and then studied cecal ion tran

The group factor 3,4 somatic antigen was transferred by recombination from a donor strain of Shigella flexneri type 2a to the Escherichia coli O15 rabbit pathogen strain RDEC-1. A hybrid clone (7482-1-1) that expressed only the S. flexneri 3,4 somati

An in vitro tissue culture plaque assay was developed to investigate the intracellular replication and intercellular spread of virulent shigellae. Shigella plaques were formed in HeLa cell monolayers in the presence of an agarose overlay containing t
