By Liji Thomas, MD. Dysentery is an infection of the intestines which causes the passage of bloody stools mixed with mucus. It is caused either by bacteria such as Shigella, or by parasites such as Entamoeba.These forms are called bacillary dysentery, or shigellosis, and amoebic dysentery respectively.iagnosis is based on a history of possible contact with the parasite or bacteria, such as travel abroad, confirmed by other tests: 1  Blood tests for Entamoeba or Shigella. 2  Stool tests. 3  Microscopy for the presence of the parasite or bacteria.
Shigella infection is typically by ingestion (fecalâoral contamination); depending on age and condition of the host, fewer than 100 bacterial cells can be enough to cause an infection. Shigella causes dysentery that results in the destruction of the epithelial cells of the intestinal mucosa in the cecum and rectum.Some strains produce the enterotoxin shiga toxin, which is similar to the verotoxin of E. coli O157:H7 and other verotoxin-producing E. coli.higella species are classified by four serogroups 1  : Serogroup A: S. dysenteriae (15 serotypes). 2  Serogroup B: S. flexneri (six serotypes). 3  Serogroup C: S. boydii (19 serotypes). 4  Serogroup D: S. sonnei (one serotype).
