Samples of 10 and 14 Ctenocephalides felis felis fleas were collected on dogs from Pedreira and Mogi das Cruzes municipalities, respectively, in the State of São Paulo, Brazil, for detection of Rickettsia spp. Individual fleas were submitted to Polymerase Chain Reaction targeting the 17-kDa and the 190-kDa (OmpA) genes of Rickettsiae. This later gene is specific for spotted fever group. Nine fleas from Pedreira (90%) and four fleas from Mogi das Cruzes (28%) were positive for the 17-kDa gene, and eight fleas from Pedreira (80%) and four from Mogi das Cruzes (28%) were positive for 190-kDa gene. The nucleotide sequence of the 190-kDa products of one flea from Pedreira and one flea from Mogi das Cruzes were 100% identical to each other, and when compared to the GenBank Data, they were 100% identical to the 190-kDa sequence of R. felis. This was the first report of its occurrence in the State of São Paulo.

Ctenocephalides Canis

Ctenocephalides felis felis is one of the most important ectoparasites of dogs and cats throughout the world, because of its geographical distribution, dual parasitological action as an infesting agent and a vector of diseases, the economic losses and the acquired resistance against common insecticides. In Brazil, it surpasses Ctenocephalides canis in distribution, number of host species infested, prevalence and epidemiological importance. However, in some studies the species have been misidentified on the basis of their morphological characters included in taxonomic keys. The morphological variations of chaetotaxy, especially those on the dorsal margin of the hind tibia and lateral metanotal area (LMA), found in certain specimens, have sometimes been erroneously treated as hybrids, in spite of the nonexistence of the two species of Ctenocephalides in the same municipality or region. This review focuses on the characteristics used for interspecific diagnosis and intraspecific variations found between the species. Data on distribution, hosts, prevalence and parasitological action are also presented as an auxiliary means for recognizing the species.
