Intestinal myiasis in a dog

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

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.

Treatment protocols for demodicosis: an evidence-based review

Publications discussing the treatment of demodicosis in the dog and cat are reviewed. Based on the evidence in the literature, amitraz rinses at 0.025-0.06% every 7-14 days, and oral daily ivermectin at 300 micro g kg(-1), milbemycin at 2 mg kg(-1) and moxidectin at 400 micro g kg(-1), respectively, can all be recommended for the treatment of generalized canine demodicosis. Ivermectin and moxidectin should be initiated at lower doses and patients monitored for possible adverse effects during therapy. In cats, 2% lime sulfur dips and amitraz rinses at 0.0125-0.025% have been used successfully.
