Some fish parasites can cause a variety of symptoms in humans, including allergies. This was a cross-sectional study based on interviews, serum analysis by ELISA for anti-Pterobothrium heteracanthum IgG and a statistical evaluation. Four individuals were seroreactive (6.25%), with no association with fish handling (p = 1.000) or with ingestion more than twice a week (p = 0.232). There was a significant association (p = 0.032) between reactivity and the absence of allergy symptoms. Seroreactivity against P. heteracanthum in humans was detected, but was not associated with the amount of fish ingested, handled, or with allergic complaints.
Alguns parasitos de peixes podem causar uma variedade de sintomas em humanos, incluindo alergias. Este foi um estudo transversal baseado em entrevistas, análise sérica por ELISA para IgG anti–Pterobothrium heteracanthum e avaliação estatística. Quatro indivíduos foram sororreativos (6,25%), sem associação com o manuseio dos peixes (p = 1,000) ou com a ingestão maior que duas vezes por semana (p = 0,232). Houve associação significativa (p=0,032) entre reatividade e ausência de sintomas alérgicos. A sororreatividade contra P. heteracanthum em humanos foi detectada, mas não foi associada à quantidade de peixe ingerido, manuseado ou a queixas alérgicas.
