is an emerging human pathogen associated primarily with the cat flea . In this study, we investigated the presence of in from Guatemala and Costa Rica. were collected directly from dogs and cats, and analyzed by polymerase chain reaction for -specific fragments of 17-kDa protein, OmpA, and citrate synthase genes. DNA was detected in 64% (55 of 86) and 58% (47 of 81) of flea pools in Guatemala and Costa Rica, respectively. Sequencing of A fragments identified genotype URRWXCal in samples from both countries, and genotype Rf2125 in Costa Rica. This is the first report of in Guatemala and of genotype Rf2125 in Costa Rica. The extensive presence of this pathogen in countries of Central America stresses the need for increased awareness and diagnosis.
