Description
Summary:•A possible Strongyloides stercoralis transmammary transmission in dogs is described•Four puppies possibly acquired Strongyloides stercoralis from the milking dam•Actual circulation of this neglected zoonotic parasite in Central Italy is reported Strongyloides stercoralis is a soil-transmitted helminth with an unusual life cycle, causing canine and human strongyloidiasis, mainly endemic in tropical and subtropical areas. Following percutaneous or oral transmission of infective third-stage larvae in the vertebrate host, the parasite can cause autoinfection, leading to life-long infection. At present, the transmammary transmission was only assessed in experimentally infested dogs. Here, we provide observational evidence of S. stercoralis transmammary transmission in puppies suckling from a truffle dog from Central Italy, from where its presence was neglected. [Display omitted]
