Effects of Aeromonas caviae co-cultured in mouse small intestine

the ultrastructural aspects generated by the interaction between two strains of aeromonas caviae with mouse intestinal mucosa are described. one of the strains was isolated from an asymptomatic patient and the other one from a patient with diarrhea. both strains were separately inoculated in closed cylinders of mouse small intestine and the whole preparations were incubated in eagle？s culture medium. the intestinal cylinders were divided into two groups, one was incubated for 24h and the other for 48h. samples of the co-cultures were processed for analysis using high resolution light microscopy and transmission electron microscopy. the strain isolated from the asymptomatic patient showed variable alterations in the intestinal mucosa, according to the different periods of incubation, whereas the one obtained from the patient with diarrhea always produced severe enteropathogenic effects
