Canine Myiasis and Its Causal Agents in Northeastern Iran
AbstractBackground: Myiasis is defined as the infestation of live human and vertebrate animals with dipterous larvae for a certain period. There are reports indicating that dogs are the most common species affected by myiasis. This study was conducted to identify myiasis-causing flies in owned and stray dogs in Mashhad (Northeastern Iran). Methods: A total of 435 owned dogs and 800 stray dogs were examined for myiasis. Myiasis cases were cured and fly larvae were identified by microscopy using the relevant standard identification keys.Results: Ten out of 435 owned dogs (2.29 %) and 18 out of 800 stray dogs (2.25 %) had myiasis. The causative agents of myiasis in dogs based on their frequencies were as follows: Wohlfahrtia magnifica (50%), Lucilia sericata (28.57%) and Chrysomya albiceps (21.42%).Conclusion: W. magniﬁca was the most important myiasis-causing ﬂy among the dogs sampled here, sometimes causing very serious damages. However, when treatment was given early enough, the larvae removed and the wound disinfected, the animals usually made a full recovery.
