[QUOTE="wbvs58, post: 1514255, member: 16453"] Ron, I may be wrong but my from my memory tetanus organisms live in the gut of many animals and this may be where the horses are incriminated. The faeces of animals contain the spores which contaminate the ground. Tetanus is an anaerobic bacteria so likes deep puncture wounds with surrounding tissue bruised hence minimal blood supply and low oxygen. In a situation with banding I do not think conditions are favourable for tetanus, the strangulated bit drops off and the torniquet effect will not allow tetanus toxins into the blood supply and when the scrotum falls off the small wound is fairly open with good oxygen and not conducive for tetanus to survive. Passive immunity from colostrum may also help with banding at birth. I have said this several times on CT, tetanus spores can enter a body through a vascular wound which does not favour the spores to multiply and they just sit in the likes of muscle tissue for several months and then say a horse gets transported loose in a truck with other horses and bruising of that muscle occurs creating a lower oxygen environment for the spores then they multiply and you get full blown tetanus. I have seen this a couple of occaisions. FWIW, my FIL had several horses with tetanus over a short period of time (he was a horse trader) and he always blamed the ducks he had swimming and walking around his dam. When he got rid of the ducks the tetanus cases disappeared. Ken [/QUOTE]
