- snake bite:
- Bacteriology of rattlesnake venom and implications for therapy.
- cat bite: (see cat scratch disease)
- consider pasteurella multocida; note P. multocida infection develops within 24hrs;
- with bites on the finger observe for osteomyelitis;
- may transmit tularemia and rabies;
- prophylactic treatment: augmentin / amoxicillin or with allergy (cipro + clindamycin)
- w/ estabilished infection: unasyn or with allergy (cipro + clindamycin) or ceftriaxone

- Brown Recluse Spider Bites
- brown recluse spider is also know as loxoscelism;
- can be up to 5 cm in length / 3 pairs of eyes as opposed to 4 pairs of eyes / characteristically has a violin shaped mark on its cephalothorax;
- bite often results in full thickness skin loss;
- magnitude of tissue injury depends on the amount of venom injected and on the patient's immune status;
- surrounding erythema may spread quickly (adjacent pallor and cyanosis is common);
- non healing ulcer with red, white, and blue phenomenon (erythema, ischemia, and cyanosis)
- untreated, lesion can take more than one month to heal;
- diff dx: pyoderma gangrensum:
- treatment:
- treatment with dapsone and antibiotics may reduced the prevalence of secondary infections as well as the need for surgery;

- Rat:
- streptobacillus moniliformis;
- try ampicillin or tetracycline; antirabies Rx not indicated;
- Bat, Racoon, Skunk:
- rx ampicillin or tetracycline;
- in americas, antirabies Rx indicated, rabies immune globin + vaccine;
- Rabies:
- animals at high risk for rabies: bats, cats, cattle, coyotes, dogs, foxes, skunks, racoons;
