| interactions of salmonella enterica subsp. enterica serovar muenchen with intestinal explants of the turtle trachemys scripta scripta. | salmonella infections in reptiles, in contrast to those in birds and mammals, are limited to the intestinal tract. in this study, interactions of a strain of salmonella enterica subsp. enterica serovar muenchen (seem) with intestinal explants of the turtle trachemys scripta scripta were examined by scanning electron microscopy (sem). adhesion and invasion in the chelonian intestinal explants at 30 degrees c and 37 degrees c were evaluated quantitatively. for purposes of comparison, the invasive ... | 2003 | 12634088 |
| pathogenesis of infections with salmonella enterica subsp. enterica serovar muenchen in the turtle trachemys scripta scripta. | the pathogenesis of salmonella enterica subsp. enterica serovar muenchen infections in the aquatic turtle trachemys scripta scripta was studied. after oral infection with 5x10(5)cfu of serovar muenchen of 10-14-month-old turtles, kept at 26 degrees c, the intestine and especially the ileum, caecum and colon was colonized. invasion of the intestinal wall, causing histopathological lesions, and colonization of internal organs were not observed. serovar muenchen was only isolated from turtles for 8 ... | 2002 | 12069769 |
| interactions of salmonella enterica serovar muenchen with macrophages of the turtle trachemys scripta scripta. | interactions of salmonella with macrophages have been studied in birds and, most extensively, in mammals. in these homeothermic animals, interactions between salmonella and macrophages are characterized by the following processes. after macropinocytosis, spacious phagosomes are formed within the macrophage. partial inhibition of phagosome-lysosome fusion and resistance to the formation of reactive oxygen species and reactive nitrogen intermediates enable the bacterium to survive and even multipl ... | 2002 | 11755678 |
