A Case of Auricular, Anal and Umbilical Myiasis Caused by the Larvae of Phormia regina (Meigen) (Diptera: Calliphoridae) in Neonatal Kittens

Abstract

ÖZETKedilerde myiasis görülmesi nadirdir. Erken aşamada tedavi edilmezse dipteran larvaların yoğun enfestasyonu ölüme yol açabilir. Yeni doğan üç kedi yavrusunda aural, anal ve umbilikal myiasis tespit edildi. Dipteran larvalar toplandı, %70'lik alkolde tespit edildi ve %10'luk KOH'de birkaç gün şeffaflandırıldı. Daha sonra larvalar steromikroskop altında diseke edildi, preparatlar hazırlandı ve daha sonra stigma ve cephaloskeleton yapılarına göre üçüncü dönem black blowfly, Phormia regina (Meigen) (Diptera: Calliphoridae) olarak teşhis edildi. Orijinal ölçüler ve şekiller sunuldu. Tedavi mekanik olarak larvaların uzaklaştırılmasını ve polyvinylpyrrolidone-iodine kompleks ile bölgenin temizlenmesini kapsamaktadır. Türkiye'de kedilerde P. regina'nın varlığı ilk kez bildirilmektedir.

Massive infestations of dipteran larvae can lead to death if not treated at an early stage. Auricular, anal and umbilical myiasis was detected in three neonatal kittens. The dipteran larvae were collected, fixed in 70% alcohol and clarified with 10% KOH for a few days. Later, larvae were dissected under the stereomicroscope, mounted on slides and then identified as the third instar of the black blowfly, Phormia regina (Meigen) (Diptera: Calliphoridae), according to their stigmatic and cephaloskeleton structures. Original measurements and figures are presented. Treatment included mechanical removal of larvae and cleansing of the area by applying polyvinylpyrrolidone-iodine complex. The presence of P. regina in cats has been reported here for the first time in Turkey. (Turkiye Parazitol Derg 2014; 38: 71-5)

Cutaneous myiasis in cats and dogs: Cases, predisposing conditions and risk factors

“…Obesity prevented the cats from performing self‐cleaning, leading to painful, putrid‐smelling ulcers on the thighs and tails (Rodríguez & Perez, 1996). Other cutaneous myiasis involving skin lesions not caused by trauma have been reported in umbilical regions of neglected newborn cats and dogs (Pekmezci et al., 2014; Rawlins et al., 1983).…”

Myiasis in domestic cats: a global review

“…It has been reported as agent of myiasis in cattle [138] and humans, infesting wounds in individuals destituted, neglected or with psychiatric problems [139–142] or causing gastrointestinal [143] and auricular myiasis [140]. Cases of myiasis by P. regina were reported in Turkey in the auricular, anal and umbilical regions of three newborn kittens; the multiple site infestation occurred because the kittens had been neglected [144].…”
