Figure 4. Representation polymerase chain reaction of a 434-bp amplification product of rickettsial 17-kDa protein gene and digestion with AluI from fleas collected in Texas. Lane 1: D-15 DNA marker (Novex). Lanes 2 and 3: purified 17-kDa-fragment amplification product from Rickettsia typhi-infected Vero cells and AluI digest, respectively. Lanes 4 and 5: purified 17-kDa-fragment amplification product from colony-raised R. felis-infected fleas and AluI digestion, respectively. Lanes 6 and 7: purified 17-kDa-fragment amplification product from R. typhi-infected fleas collected in Texas and AluI digestion, respectively. Lanes 8 and 9: purified 17-kDa-fragment amplification product from R. felis-infected fleas collected in Texas and AluI digestion, respectively.
