The dusky pigmy rattlesnake (Sistrurus miliarius barbouri) is a pit viper (Crotalidae family) along with diamondback rattlesnakes, water moccasins, and copperheads. Although it is a small snake, it is responsible for envenomations requiring hospitalization. We present the case of a 54-year-old man who was bitten in the left index finger with onset of coagulopathy successfully treated with crotalidae polyvalent immune fab (CPIF) antivenom.

Snake venom proteins show high levels of variation at the level of the individual yet the environmental and molecular mechanisms that generate this diversity remain unclear. Here we report the results of a controlled feeding experiment combined with proteomic analyses of periodically collected venom samples to assess the roles of ontogenetic and diet-related effects on venom composition of captive juvenile and adult Dusky Pigmy rattlesnakes (Sistrurus miliarius barbouri). Juvenile snakes fed from birth with mice, lizards, or frogs showed little evidence for an ontogenetic shift in venom composition from 5 to 26 months in terms of substantial changes in the relative abundance of major classes of venom toxins.

Between September 1997 and March 1998, a severe skin, eye, and mouth disease was observed in a population of dusky pigmy rattlesnakes (Sistrurus miliarius barbouri), at the Lake Woodruff National Wildlife Refuge in Volusia County, Florida (USA). Three affected pigmy rattlesnakes were submitted for necropsy. All snakes had severe necrotizing and predominantly granulomatous dermatitis, stomatitis, and ophthalmitis, with involvement of the subadjacent musculature and other soft tissues.
