破傷風菌
If the flea is left within the skin, dangerous complications can occur including secondary infections from trapped bacteria such as "Staphylococcus", "Streptococcus", enterobacteriaceae, and "Clostridium tetani". Lingering effects may include loss of toenails and toe deformation. These seem to be commonplace especially where heavy infestations combine with unsanitary conditions and poverty.
