ABSTRACT
Two cases of cutaneous myiasis diagnosed in 2018 in Emilia-Romagna region (northern Italy) were reported. The first one, described in a domestic cat Felis silvestris catus L. (Carnivora: Felidae) and caused by Calliphora vicina Robineau-Desvoidy (Diptera: Calliphoridae), was the first one of this type ever reported in Italy in cats. The second one was described in a domestic dog Canis lupus familiaris L. (Carnivora: Canidae) and caused by Lucilia sericata (Meigen) (Diptera: Calliphoridae) and was unusual because it occurred in absence of lesions. An extensive literature search on cutaneous myiasis in these two domestic animal species was performed in order to draw attention to predisposing conditions and risk factors.

The report describes a case of urogenital myiasis in a domestic rabbit Oryctolagus cuniculus L. (Lagomorpha: Leporidae) caused by Lucilia sericata (Meigen; Diptera: Calliphoridae) in region Emilia-Romagna (Northern Italy). The case, occurring in June 2018, is the first one involving L. sericata as an agent of myiasis in a domestic rabbit in Italy. Species identification was based on morphological investigations of males through identification keys. The rabbit developed the urogenital myiasis as a consequence of chronic enteritis causing an accumulation of faeces in the perianal and perineal region.

Myiasis is an infestation caused by larvae of Diptera in humans and other vertebrates. In domestic cats, Felis silvestris catus L. (Carnivora: Felidae), four dipteran families have been reported as agents of obligatory and facultative myiasis: Oestridae, Calliphoridae, Sarcophagidae and Muscidae. Among agents of obligatory myiasis, the most frequent genus is Cuterebra Clark (Oestridae) and the most frequent species is Cochliomyia hominivorax (Coquerel) (Calliphoridae). Among the agents of facultative myiasis, the most frequent species is Lucilia sericata (Meigen) (Calliphoridae). A survey of myiasis in cats reported in literature shows that the cases are distributed worldwide and linked to the geographical range of the dipteran species. Factors favouring the occurrence of myiasis in cats are prowling in infested areas, poor hygiene conditions due to diseases and/or neglect, and wounds inflicted during territorial or reproductive competition. The aim of the review is to provide an extended survey of literature on myiasis in cats, as general information and possible development of guidelines for veterinarians, entomologists and other researchers interested in the field.

We describe five cases of myiasis of domestic cats, Felis silvestris catus L. (Carnivora: Felidae), reported in 2016 in northern Italy and caused by three Diptera species: Sarcophaga argyrostoma (Robineau-Desvoidy) (Sarcophagidae), Calliphora vicina Robineau-Desvoidy and Lucilia sericata (Meigen) (Calliphoridae). Three were cases of traumatic myiasis, one by S. argyrostoma and two by L. sericata, one was a case of auricular myiasis by C. vicina and one was a case of ophthalmomyiasis caused by an association of L. sericata and C. vicina. The myiasis by S. argyrostoma is the first reported case of this species in a cat, whereas the two myiases by C. vicina are the first reported cases in cats in Italy.
