Furuncular myiasis caused by the human bot-fly Dermatobia hominis in a domestic cat from Brazil.

This paper reports a case of furuncular myiasis caused by the human bot-fly Dermatobia hominis in a domestic cat from Brazil. A crossbred shorthaired female cat of approximately 3 years old, presented with three boil-like cutaneous lesions at the left cranioventral region of the neck. These were diagnosed as furuncular myiasis. The animal was sedated, and after shaving the fur, bot-fly larvae were removed from the lesion by digital compression. Afterwards, the wounds were treated with 10% iodine solution and also with wound-healing cream containing sulfanilamide, urea and beeswax. Maggots were identified as third-stage larvae of D hominis. Clinical case reports of human bot-fly myiasis in cats are relevant due to its scarce occurrence in feline veterinary practice in some countries.

Myiasis caused by the New World screwworm fly Cochliomyia hominivorax (Diptera: Calliphoridae) in cats from Brazil: report of five cases.

This paper reports five cases of intact adult male crossbreed cats presenting with myiasis caused by Cochliomyia hominivorax. Three were stray animals that died despite treatment due to the severity of lesions while two were client-owned cats previously treated with cryosurgery which completely recovered. Myiasis caused by the New World screwworm fly in cats appears to be more frequent than previously thought, deserving more attention from both veterinary practitioners and owners.

[Miticidal efficacy of thiabendazole against Otodectes cynotis (Hering, 1838) in dogs]. / Eficácia acaricida do tiabendazol sobre Otodectes cynotis (Hering, 1838) em cães.

The aim of the present study was to evaluate the efficacy of thiabendazole on the treatment of Otodectes cynotis infestations in dogs. Ten naturally infested beagle dogs were used. The mites were diagnosed through otoscopy. Dogs were examined three days before treatment (day -3) and on the treatment day (day 0). They were randomly divided into two groups, five animals for the control group and five for the treated. During seven days, was applied in both ears of the treated dogs 1ml of the thiabendazole 5% solution, which correspond to 50mg of the product. All animals were reexamined through otoscopy on days +1, +3, +7, +10, +17, +24 and +31. The dogs on the control group showed mites in both ears during the whole period of observation. On the treated group the efficacy varied from 20% on the left ear to 80% on the right ear, on the first day after treatment. On days +3, +7, +10, +17, +24 and +31 the medium efficacy was 100% on both ears. The thiabendazole was efficient on the elimination of O. cynotis in dogs when used on the dose of 50mg per ear during seven following days.
