Abstract:
There are reports in the literature stating that Campylobacter infections can cause hemolytic uremic syndrome (HUS); however, a mechanism for how Campylobacter induces HUS has not been proposed by investigators. The most common bacterial inducer of HUS is the Shiga toxin–producing Escherichia coli (STEC), and a few cases of HUS are induced by an invasive Shigella dysenteriae or Streptococcus pneumoniae infection. Campylobacter spp. have not been shown to produce Shiga toxin (Stx) nor do they possess genetic elements capable of producing a Stx-like toxin. The neuraminidase associated with pneumococcal HUS has not been observed in Campylobacter. Therefore, in the absence of a well-defined toxic mechanism, it not clear that Campylobacter actually causes HUS.
