the bacterial contaminant. The more virulent the bacterial contaminant‚ the greater the probability of infection. Coagulase-positive staphylococci require smaller inoculums than the coagulase-negative species. Uncommon but virulent strains of clostridium perfringens or group A streptococci require a small inoculums to cause

Tetanus is a medical condition characterized by a prolonged contraction of skeletal muscle fibers. The primary symptoms are caused by tetanospasmin‚ a neurotoxin produced by the Gram-positive‚ rod-shaped‚ obligate anaerobic bacterium Clostridium tetani. Clostridium tetani spores can be found most commonly in soil‚ dust and manure‚ but also exist virtually anywhere. If deposited in a wound the neurotoxin interferes with nerves that control muscle movement. The signs and symptoms of tetanus
