Anche gli animali sviluppano resistenza agli antibiotici e per alcune specie la situazione sta diventando drammatica, stando a quanto rivelato da Caroline Frey, responsabile della diagnostica veterinaria all’istituto di parassitologia di Berna.
Cavalli e piccoli ruminanti (capre e pecore) vengono infettati da parassiti che non vengono più eliminati dai medicinali che in passato erano risultati efficaci, e le conseguenze sono spesso fatali.
Certo, l’industria farmaceutica non ha tardato a reagire e ha sviluppato un medicinale di riserva che permette di combattere i vermi resistenti, ma si tratta di una soluzione momentanea.
Le cause sono da ricercare nella somministrazione agli animali di dosi troppo elevate di medicinali. Secondo Vetsuisse tutto il trattamento vermifugo deve essere ripensato: in primis gli animali andrebbero trattati solo quando necessario e non preventivamente.
