Zoonoses from dogs with special reference to Egypt.

A zoonosis is an animal disease that is transmissible to humans. humans are usually an accidental host that acquires disease through close contact with an infected animal,who may or may not be symptomatic. children are at highest risk for infection because they are more likely to have close contact with pets. dogs are responsible for transmission of an extensive array of bacterial and parasitic zoonotic pathogens. the route of transmission can be through the feces,urine,saliva (eg,bites or contaminated scratches),or respiratory secretions of the animal,or by the dog or cat acting as a vehicle and source of tick or flea exposure or reservoir for vector borne disease. although dogs have been implicated in transmission of zoonoses to their owners,risk of transmission from contact with dogs is low and may be further reduced by simple precautions.
