The first reported case of accidental intestinal myiasis in a domestic dog by the flesh fly, Sarcophaga africa (Wiedeman, 1824)

Abstract

Myiasis occurs when fly larvae, or maggots, feed on the tissue, secretions or digestive content of a live vertebrate. Here, a rare case of accidental intestinal or enteric myiasis is reported in a domestic dog. The species of fly is molecularly identified as Sarcophaga africa (Wiedeman, 1824) using the barcoding region of cytochrome oxidase I (COI). A brief critique on the usage of the term "pseudomyiasis" is provided and the complex taxonomy of S. africa is briefly summarised in order to shed light on the erroneous use of S. cruenata and S. haemorrhoidalis with obvious downstream effects. Finally, a comparative assessment to the limited cases in the literature is provided. These few cases are however highly fragmented and our understanding of accidental intestinal myiasis and the clinical manifestations thereof remain incomplete.
