Title : Age in cardiopulmonary dirofilariasis of dog. Consequences on chemoprophylaxis.
Authors : F. BEUGNET, V. ROUS, M. LEURS et L. CHARDONNET.
Summary : Canine dirofilariasis is an endemic helminthiasis in New-Caledonia. Its prevalence has been studied in 124 stray dogs. Diagnosis based on filtration technique and research of microfilariae. A strong correlation was found between age of dogs and prevalence : 7,7 p. 100 of 6 months to 1 year-old dogs were infected, as compared to 33,33 p. 100 of the dogs in the range 1-2 years-old, 53 p. 100 of the 2-3 years-old ones, 77,4 p. 100 of the 3-5 years-old ones and 80 p. 100 of the animals that were older than five. Regression studies showed that the evolution was not linear, and that age has an epidemiologic impact which is not a simple cumulative effect. Thus, the infection risk depends on age. Dogs less than 1 year are less receptive or less infected than older ones. Infections seem to be uncommon in animals less than 6 months. Therefore chemoprophylaxis should begin at this age.
