Aislamiento y caracterización de Escherichia coli O157 en productos cárnicos bovinos y medias reses en la provincia de Tucumán
The aims of this study were to characterize E. coli O157 isolated from cattle and meat products collected from abattoirs and retail stores, to establish the clonal relatedness among regional isolates and to compare them with those in the national database.
Physical and Immunological Effects of Lactobacillus acidophilus La-5 against Escherichia coli O157:H7
Physically and immunologically, L. acidophilus La-5 overwhelmed E. coli O157:H7 pathogenicity against intestinal and kidney tissues in murine model via know-hows physical and immune modulating effects and immunological effects.
Aplicación de componentes alimentarios en problemas de salud asociados a estrés oxidativo: selección de compuestos con propiedades antiradicalarias a partir de almentos o productos alimenticios regionales
El Sindrome Uremico Hemolitico (SUH) mediado por Escherichia coli productora de Verotoxinas es la causa mas comun de falla renal aguda en ninos menores de 5 anos y Argentina es el pais con mayor
Rapid and sensitive detection of Escherichia coli in milk by 16S rRNA gene targeted PCR
The present study was conducted to optimize PCR amplification targeted against E. coli DNA for detection of 14 different pathogenic and non- pathogenic strains of this organism in milk. 16S rRNA gene


Síndrome urémico hemolítico en niños de Mendoza, Argentina. Asociación con la infección por Escherichia coli productor de toxina Shiga
Escherichia coli productor de toxina Shiga (STEC) ha sido asociado with the etiopatogenia del sindrome uremico hemolitico (SUH) observados en Mendoza y determinar su asociacion with the infeccion por STEC.
A genetic locus of enterocyte effacement conserved among diverse enterobacterial pathogens.
It is reported that in EPEC a 35-kbp locus containing several regions implicated in formation of these lesions is found, which hybridize to E. coli O157:H7 and other pathogens of three genera that cause similar lesions but do not hybridized to avirulent members of the same species.
Comparative Analysis of EspF from Enteropathogenic and Enterohemorrhagic Escherichia coli in Alteration of Epithelial Barrier Function
R reverse transcription-PCR analyses revealed coordinate regulation of EHEC U-espF and the LEE-encoded espF, with enhanced expression in bacteria grown in Dulbecco-Vogt modified Eagle’s medium compared toacteria grown in Luria broth, which reveals further similarities and differences in the pathogenesis of EPEC and EH EC.

Lipid heterogeneity of Gb3 is important in binding, and may define a growth-related signal transduction pathway used by verotoxin, which explains the epidemiology of renal pathology, which may follow VTEC infection.
Dysentery Caused by Escherichia coli (S102-9) in Calves: Natural and Experimental Disease
In two of five calves with natural disease, the adherent bacteria did not stain by the immunoperoxidase method with antisera raised against E. coli (S102-9), indicating that there was possibly more than one bacterial cause of the syndrome.
Enterohaemorrhagic Escherichia coliO157:H7 target Peyer's patches in humans and cause attaching/effacing lesions in both human and bovine intestine
O157:H7 targets follicle associated epithelium in humans where it causes attaching/effacing lesions in humans, indicating that similar pathogenic mechanisms operate across human and bovine species.
Diarrheagenicity evaluation of attenuated Vibrio cholerae O1 and O139 strains in the human intestine ex vivo.
It is found that human tissues incubated with supernatants from the attenuated 638, 413 and 251a V. cholerae strains caused no changes in the ion conductances and water absorption in ileal and colon tissues allowing them to be assayed in volunteers.
Shiga Toxins Stimulate Secretion of Interleukin-8 from Intestinal Epithelial Cells
A novel model of how Stx contribute to disease is suggested, namely that Stxs may alter regulation of host cell processes in sensitive cells via activation of at least one member of the mitogen-activated protein kinase family in the p38/RK cascade and induction of c-jun mRNA.
Non-O157 Shiga toxin-producing Escherichia coli isolated from diarrhoeic calves in Argentina.
It is shown that highly virulent STEC strains are being shed by diarrhoeic calves from farms located in a high incidence area of human STEC infections.
Effect of Shiga Toxin 2 on Water and Ion Transport in Human Colon In Vitro
It is suggested that Stx2 inhibits water absorption across the human colon by acting on a specific cell population: the mature, differentiated absorptive villus epithelium.
