Urban stray cats infested by ectoparasites with zoonotic potential in Greece

A large population of stray cats is encountered in many urban areas sharing the same environment with people, usually being in a close direct contact with them. A variety of ectoparasites can infest such cats, causing mild dermatological abnormalities to more severe systemic disorders. In order to determine the extent of which stray cats carry ectoparasites, particularly those of zoonotic potential, 341 stray cats originating from the urban area of Thessaloniki, Greece, were examined between 2012 and 2014. The signalment of each cat such as gender, hair length, and roughly estimated age were recorded. From a total of 341 examined stray cats, 127 (37.24 %; 95 % confidence interval (CI) 32.14-42.64) were infested with at least one of the following ectoparasites: mites-Otodectes cynotis (15.8 %), Notoedres cati (2.35 %), Cheyletiella blakei (2.05 %); fleas-Ctenocephalides felis (24.3 %); ticks-Rhipicephalus sanguineus (0.88 %); and lice-Felicola subrostratus (0.59 %). A significantly higher prevalence of ectoparasites was observed in long-haired individuals (p < 0.00001). The above ectoparasites may either cause or transmit diseases not only in cats but also in humans Therefore, antiparasitic control should be included in stray cat neutering campaigns while public health education for taking preventive measures will decrease the risk of transmission to humans
