RESUMO

Background: Asticot maggot (Blowfly, Calliphoridae family) is the most important live bait used for angling in our country. Prevalence of allergy to live fish bait in occupationally exposed workers has been described. The purpose of this study was to determine the prevalence of asticot allergy in amateur fishermen and the identification of marketed asticot species in Cáceres, Spain. Materials and Methods: Seventy-two randomised selected patients (Angler’s Society of Cáceres) completed a questionnaire about fishing habits and allergic symptoms related with live baithandling. Skin prick test (SPT) with local asticot and common earthworm extracts were performed. Serum IgE levels to imported species (Protophormia terraenovae, Calliphoravomitoria, Lucilia sericata, Lumbricus terrestris) were measured. Local asticot and commone arthworm samples were obtained for taxonomic identification. Data were analysed using the SPSS 12.0 software. Results: Five patients (7 %) reported allergic symptoms caused by asticot maggots. All of them were positive for SPT to asticot and specific IgE to P. terraenovae. Sensitisation to P. terraenovae was found in 40 patients (58.8 %). No associated factors for asticot allergy were observed. Larvae and adult flies of local asticot samples were identified as P. terraenovae. Conclusions: Commercially available asticot, in Cáceres, is composed by P. terraenovae larvae (Diptera. Calliphoridae). A 7 % prevalence of P. terraenovae allergy in amateur fishermen of Cáceres was obtained. The allergenic potential of P. terraenovae seems to be greater than thatof other blow flies and L. terrestris. The SPT with P. terraenovae extract is a very sensitive and specific technique in the diagnosis of live bait allergy in fi shermen (AU)
