Synopsis
CAPC Recommends The CAPC recommends administration of preventive flea products as soon after birth as possible (consistent with label claims) for the life of the pet. However, because substantial geographic differences occur in flea prevalence and seasonality, prevention programs should be tailored to needs of the individual pet.
Species
Rickettsia typhi (murine typhus, endemic typhus) Rickettsia felis (flea-borne spotted fever)
Disease
Cats Infections with R. typhi and R. felis are considered to be largely asymptomatic. Experimental infection of cats with R. felis results in seroconversion between 2-4 months post infection, but no overt disease.
Diagnosis
Rickettsemia associated with R. typhi and R. felis infections may quickly drop to undetectable levels. Due to cross reactivity among the Rickettsia species, multiple serologic tests may be required to confirm diagnosis of R. typhi or R. felis infections.
Treatment
Standard protocols are not available for antibiotic treatments of cats or dogs infected with R. typhi or R. felis . People with clinical disease due to R. typhi are treated with tetracycline, doxycycline, or fluoroquinolone antibiotics.
Control and Prevention
The key to prevention of flea-borne rickettsiosis in both dogs and people is to limit exposure to potentially infected fleas. Routine use of flea control containing adulticides with an insect growth regulator or insect development inhibitor, which will help prevent establishment of an environmental infestation, should be administered as needed to every animal, every month, all year long.
Public Health Considerations
The vector fleas and preventive strategies (flea control) are similar for pets and people. While subclinical in animals, R. typhi and R. felis infections can be associated with clinical disease in people, including fever, rash, myalgia, and neurologic complications.
