Primary Myiasis in Dog Caused by Phaenicia eximia (Diptera: Calliphoridae) and Preliminary Mitochondrial DNA Analysis of the Species in Brazil

Abstract

A case of primary myiasis in a dog caused by Phaenicia eximia (Robineau-Desvoidy) in Brazil is presented. A young and healthy female dog, Canis familiaris, ≈10 d old and still under maternal care, was found to have several eggs and 1st instars larvae in its abdomen and urogenital regions. Samples were collected in Campinas, São Paulo, and transferred to the laboratory for rearing and identification. A comparative analysis of the mitochondrial DNA (mtDNA) with 12 restriction enzymes in 2 sampled populations of P. eximia collected in different hosts (live dog and bovine carcass) and in the same locality revealed that 4, EcoRI, EcoRV, HaeIII, and MspI were suitable for detecting mtDNA markers in the 2 populations.
