Nisbet A J & Huntley J F (2006) Progress and opportunities in the development of vaccines against mites, fleas and myiasis-causing flies of veterinary importance.Recent references from PubMed and VetMedResource.Botflies ( Oestridae) are obligate parasites that are harbored and feed for several weeks to months in the host's nasopharyngeal tract.įurther Reading Publications Refereed papers.Blowflies ( Calliphoridae) and fleshflies ( Sarcophagidae) cause myiases of relatively short duration, by both obligate and/or facultative parasites, which mature within 47 days, usually at the host's body orifices and in wounds (eg Cochliomyia hominivorax, and Chrysomya bezziana).In ideal conditions even eggs will hatch within 8 hours. Can be very rapid (hours) - some fly species are viviparous and deposit live maggots directly onto the skin.In the late fall the larvae enlarge producing a swelling and a fistula develops. As cats are abnormal hosts the larvae undergo aberrant migrations (ocular and neurological disease have bene repored in several cats as result of abnormal migration of larvae).
#Fly strike dermatitis in cats skin
Some larvae (eg Cuterebra) can penetrate intact skin and produce nodular lesions. Eggs are deposited on vegetation and animals become infested as they pass through contaminated areas.Body cavities may be entered leading to peritonitis Peritonitis /septicemia Shock: septic.As skin breaks down and liquefies it becomes more suitable for further infestation.Maggots damage skin and burrow under skin.Laying of Diptera eggs on unattended wounds.Poor hygiene/lack of adequate observation of pet.Some maggots (eg Sarcophagids) only attack living tissue.Some maggots are only present on dead tissues, eg Calliphorids.Cochliomyia hominovorax is still reported in the US.Diptera fly larvae, especially Lucilia sericata and other Calliphora spp.Prognosis: poor in severe cases, otherwise dependant on predisposing conditions.Treatment: clip and clean area, remove maggots, antibiotics, fluid therapy.Secondary skin infection is common and peritonitis/septicemia may be associated with entry to the body cavity. Ocular, respiratory and neurological disease have been reported in cats.Fly larvae cause alopecia and erosion/ulceration and may enter body cavities. Signs: fly strike occurs mostly in warm weather, and is usually preceded by soiling or moist dermatitis.Cause: maggot larvae of flies of the order Diptera.Classification is based on their location on the host body (dermal, subdermal, nasopharyngeal, internal organs, intestinal and urogenital) or, in parasitological terms, according to the type of hostparasite relationship (obligatory, facultative or pseudomyiases).Myiases (Greek MYIA = fly) are infestations of humans and animals with maggot larvae of flies, which feed on dead or living host tissue for a variable period.
