Case report: pulicosis por Ctenocephalides felis felis en ovinos y caprinos en la sabana de Bogotá, Colombia

Abstract

In Colombia the rearing of hair sheep and goats are expanding in various regions for being an alternative for meat and milk production at competitive prices due to their adaptability and easiness to digest rough fodder. Among the ectoparasites that affect small ruminants traditionally are recognized the lice and the sheep keds Melophagus ovinus (Díptera: Hippoboscidae), however fleas are not included. Here the occurrence of the common cat flea Ctenocephalides felis felis (Díptera: Siphonaptera) affecting sheep and goats in a farm at the Sabana de Bogotá are described an so there was performed an epidemiological and parasitological evaluation. The barn maintained animals in rotational grazing at an approximated stocking rate of 25 head/ha, receiving additional supplements of hay and silage. The presence of the flea was confirmed in sheep and goats, young and adult, as well as in dogs. Diverse degrees of anemia were evidenced but the association between flea infestation and anemia, or the presence of other anemia producing agents could not be studied. In the farm synthetic parasiticides are not used, extracts of Ruda (Ruta graveolens) are administered to mitigate parasitosis, without major efficacy. Sheep and goat breeders in the tropics should consider flea infestation as an agent causing adverse animal welfare situations in their farms. Control should start from the knowledge of the life cycle of the flea, trying to interrupt it.
