“…In Thailand, China and other Asian countries, a prevalence of 4 to 7% has been seen 426, 427, 428, 429. In Bolivia, the reports showed a 2% prevalence 430 . Some studies have shown that in Nigeria, Iran and Thailand, the distribution of EIEC is below (less than 0.1%) the rates found in developed countries; in Spain, for example, a prevalence of 0.2% was found 431, 432, 433, 434.…”

Most Escherichia coli strains live harmlessly in the intestines and rarely cause disease in healthy individuals. Nonetheless, a number of pathogenic strains can cause diarrhea or extraintestinal diseases both in healthy and immunocompromised individuals. Diarrheal illnesses are a severe public health problem and a major cause of morbidity and mortality in infants and young children, especially in developing countries. E. coli strains that cause diarrhea have evolved by acquiring, through horizontal gene transfer, a particular set of characteristics that have successfully persisted in the host. According to the group of virulence determinants acquired, specific combinations were formed determining the currently known E. coli pathotypes, which are collectively known as diarrheagenic E. coli. In this review, we have gathered information on current definitions, serotypes, lineages, virulence mechanisms, epidemiology, and diagnosis of the major diarrheagenic E. coli pathotypes.

“…The Shigella strains used were isolated in Bolivia, South America, from 1993 to 1994 (6). The isolates were maintained in a butt of Kajiton medium (Eiken, Japan) or on a slant of Dorset-egg medium (Nissui, Japan).…”

Wild-type strains of Providencia species were evaluated for their ability to invade HEp-2 monolayers based upon microscopic and semi-quantitative assays. Of 14 P. alcalifaciens strains tested, 3 (17%) were found to be highly invasive, 4 (22%) moderately invasive, and the remaining 61% weakly or noninvasive. HEp-2 invasion results were confirmed by thin-section electron microscopy. Invasive capabilities of P. alcalifaciens were greater at higher MOIs (100 to 1000) than at lower inocula (<10 MOI). No strain of P. stuartii or P. rettgeri tested invaded HEp-2 cells. Quantitative assays of Triton X-100-lysed, HEp-2-invaded cells indicated that between 0.001% and 0. 013% of the initial bacterial inoculum was gentamicin resistant. Further testing of select strains on various cell lines indicated the efficiency of invasion was Vero > Y1 > INT-407 > HEp-2. Two isolates recovered from a father and son with prolonged diarrhea after returning from Mexico were found to be identical on the basis of biotype, serotype, and genotype. These results provide additional evidence that some P. alcalifaciens strains cause gastroenteritis.
