TETANUS IS A MEDICAL CONDITION THAT IS CHARACTERIZED BY PROLONGED CONTRACTION OF SKELTAL MUSCLE FIBERS. THE PRIMARY SYSMPTOMS ARE CAUSED BY NEUOTOXIN PRODUCED BY THE ANAEROBIC BACTERIUM CLOSTRIDIUM TETANI. INFECTION GENERALLY OCCURS THROUGH WOUND CONTAMINATION, AND OFTEN INVOLVES A CUT OR DEEP PUNCTURE WOUND. AS THE INFECTION PROGRESSES, MUSCLE SPASM IN THE JAW DEVELOP HENCE THE COMMON NAME, LOCKJAW.
