Siphonaptera (Pulicidae) in dogs and cats of Colombia: Clinical and epidemiological aspects.

Flea infestation is a common worldwide problem, its effective control results in high costs and difficult implementation. During February to August 2007, an epidemiological study of Siphonaptera order in dogs and cats admitted at the University of Caldas-Colombia - Veterinary Hospital (UCVH), was carried out by corporal examination and recording epidemiological variables. Overall, 3698 fleas were collected from 140 dogs and 30 cats. Two main species were identified: Ctenocephalides felis (94.2%) and Pulex irritans (5.8%) and a single specimen of Xenopsylla cheopis were also collected. Owners also considered some products as improper or of doubtful efficacy and employed schedules defined as inadequate, both because of a poor choice and an erroneous use of the product. Epidemiological factors associated with flea infestation allowed estimating the effect of variables such as locality, sleeping area, preferred place, type of floor, presence of other animals, and type of hair. Performing epidemiological studies on canine and feline populations in other areas of the country is required for an adequate implementation of strategies for flea control in pets.
