This section is dedicated to pathogens united by their special significance in the infectious pathology of the intestinal tract and mucous membranes: reoviruses, rotaviruses, and the foot-and-mouth disease virus. Although the foot-and-mouth disease virus belongs to picornaviruses, it is often studied in adjacent modules in the educational process due to its epidemiological features and transmission mechanisms.
Inside, you will find an analysis of the structure of the unique segmented genome of reo- and rotaviruses (double-stranded RNA), the mechanisms of viral diarrhea development, and routes of infection. Special attention is paid to the foot-and-mouth disease virus—a highly contagious agent causing severe zoonotic infections with mucosal lesions.
During practical classes and exams, instructors most frequently ask about the pathogenesis of rotaviral gastroenteritis in children (the mechanism of osmotic diarrhea), rapid diagnostic methods (ELISA, PCR), and vaccine prevention. Be sure to pay attention to the segmentation of the rotavirus genome—this is a favorite question at colloquiums, explaining the pathogen's propensity for reassortment and high variability.
