ABSTRACT
Myiasis is the invasion of Diptera larvae in live vertebrates tissues. It has been registered in tropical areas, but not in urban animals of North America. Moreover, there is no information about lesions description, laboratory tests, and treatment applied to canines. We report a myiasis located in the dorsum of an overweight male canine. Insect larvae were identified as Lucilia eximia, an opportunistic species that scarcely infest live vertebrates, and with no records in North America animals before. Abnormalities of complete blood count like leukocytosis by neutrophilia and serum biochemical changes like elevations in alanine aminotransferase, aspartate aminotransferase, creatine kinase, globulins and amylase were detected. Because Lucilia is characterized by lower host-specificity and infestation outbreaks occur worldwide, it is imperative to continue increasing the understanding of Lucilia myiasis, its clinical presentation, risk factors, therapy and correct entomological classification. Otherwise, more cases could occur in animals and humans.
