To study the effect of Enterobactercloacae thermolabile enterotoxin (LT-enterotoxin) on different arms of immune system of mice.Proprietary clinical strain E. cloacae 258 was used and intraperitoneal inoculation of outbred white mice with LT-enterotoxin-producing E. cloacae comprised experimental model. Phagocytic and lysosomal activity of peritoneal macrophages as well as level of APC to sheep erythrocytes were measured, spontaneous and induced NBT tests were also performed.Pleiotropic immunotoxic effect of LT-enterotoxin of studied bacteria was established, which characterized by suppres- sion of antigen-presenting and antigen-processing functions of macrophages, stimulation of mitotic activity of lymphocytes, decrease of activity of hexose monophosphate shunt enzymes in peritoneal macrophages as well as abnormalities in formation of specific B-lymphocytes.Obtained data allowed to reveal separate steps in pathogenesis of infectious process caused by LT-enterotoxin-producing bacteria from Enterobacter genus. |
