Researchers have conducted numerous animal sentinel studies to monitor the occurrence and spread of Lyme disease. “These studies primarily focused on ticks and associated pathogens collected from domestic dogs because of their ability to produce antibodies to B. burgdorferi, attainable travel history information, and frequency of outdoor exposure,” says Hendricks. Hendricks’ team looked at confirmed

Mice, guinea pigs, dogs, rabbits and monkeys have long been used to study B. burgdorferi infections. But given that rhesus macaques have been shown to most accurately mimic human infection and response to treatment, Embers and her team inoculated rhesus macaques with B. burgdorferi. “The use of nonhuman primates to model this disease provides the

The patient was concerned she might have Lyme disease because she had repeated exposure to ticks and had reported tick bites in the past.
