Flea species from dogs and cats in northern Greece: environmental and clinical implications

Fleas were identified after being collected from 129 dogs and 38 cats of random breed, sex and age. All these animals, infested with fleas and admitted to the Clinic of Medicine of the Veterinary Faculty in Thessaloniki for routine procedures, were from different habitats and originated from various parts of northern Greece. Ctenocephalides canis was the most common species found on the dogs (71.3%). Conversely, its prevalence in the 14 cats was substantially lower (5.3%). Ctenocephalides felis was found on 97.4% of the cats and 40.3% of the dogs surveyed. Of the other flea species, with much lower prevalence, Pulex irritans (0.8%) and Xenopsylla cheopis (0.8%) were observed only on the dogs. Seventeen dogs (13.2%) and one cat (2.6%) had mixed infestations. Flea-associated dermatoses were observed in 26 dogs (20.2%) and four cats (10.5%). Flea-allergic dermatitis, with its typical manifestations, was seen in ten of the dogs (38.5%) with skin lesions. Three out of four flea-allergic cats presented miliary dermatitis and one symmetrical hypotrichosis.
