A ) Arm wounds are more susceptible to infection

B ) Salivary enzymes in cats augment infection

C ) It is difficult to cleanse pathogens from this wound

D ) The Staphylococcus species involved is particularly virulent

From emedicine
Factors that contribute to a poor prognosis include old age, attempted wound care at home, deep puncture wounds, and delayed treatment. Other risk factors include hand wounds, prosthetic joints, and immunocompromise.Because the teeth of cats are long and thin, they can potentially break off and become embedded in the wound.

From Harrisons
Cat Bites Although less common than dog bites, cat bites and scratches result in infection in more than half of all cases. Because the narrow, sharp feline incisors penetrate deeply into tissue, cat bites are more likely than dog bites to cause septic arthritis and osteomyelitis; the development of these conditions is particularly likely when punctures are located over or near a joint, especially in the hand. Women sustain cat bites more frequently than do men. These bites most often involve the hands and arms. Both bites and scratches from cats are prone to infection from organisms in the cat's oropharynx. Pasteurella multocida, a normal component of the feline oral flora, is a small gram-negative coccobacillus implicated in the majority of cat-bite wound infections. Like that of dog-bite wound infections, however, the microflora of cat-bite wound infections is usually mixed. Other microorganisms causing infection after cat bites are similar to those causing dog-bite wound infections


C ) It is difficult to cleanse pathogens from this wound seems to be most correct......
Any comments?????????????
