Disease relevance of Myiasis

• A case of mixed infection of Salmonella (type C2) and Parasarcophaga crassipalpis (an intestinal myiasis) in a two-year-old girl is reported [1].

High impact information on Myiasis

• In this review, Brian Laurence discusses the recent rapid spread of blowflies into the americas; these conspicious green flies transport a variety of gastro-intestinal pathogens between their favoured environments of latrines and exposed food, and some species are important parasites of flesh wounds, causing cutaneous myiasis [2].
• Evaluation of the prophylactic effect and curative efficacy of fipronil 1% pour on (Topline) on post-castration scrotal myiasis caused by Cochliomyia hominivorax in cattle [3].
• The respiratory and non-respiratory manifestations of human pharyngeal myiasis caused by Oestrus ovis larvae in 33 patients from the Fars province, in southern Iran, are described here [4].
• The cytochrome oxidase I (COI) gene of the most wide-spread Italian species of Oestridae larvae causing myiasis (Gasterophilus spp., Hypoderma bovis, Hypoderma lineatum, Oestrus ovis and Przhevalskiana silenus) was amplified by polymerase chain reaction (PCR) using conserved primers [5].
• Here we report the characterization of an integral peritrophic membrane glycoprotein, peritrophin-48, from the larvae of the fly Lucilia cuprina, a primary agent of cutaneous myiasis in sheep [6].

Chemical compound and disease context of Myiasis

• The results of trials on eight farms to assess the efficacy of two pour-on formulations containing cyromazine for the prevention of cutaneous myiasis of sheep are presented; data from trials on sheep with larval implants and on sheep kept in cages with adult flies are also reported [7].
• Cyromazine, a triazine insecticide, was used as a pour-on preparation to prevent blowfly myiasis in sheep kept in pairs of neighbouring farms in two locations [8].
• In five susceptible sheep with extensive cutaneous myiasis, mean plasma levels of beta-EP, ACTH and cortisol were 307 +/- 71 pg ml-1, 953 +/- 58 pg ml-1 and 232 +/- 46 nmol l-1 respectively, compared with 818 +/- 89 pg ml-1, 641 +/- 41 pg ml-1 and 107 +/- 17 nmol l-1 in six unstruck sheep handled similarly [9].
• We describe the clinical presentation of the first case, to our knowledge, of myiasis in an orbit with an exposed hydroxyapatite implant [10].
• During a survey for myiasis in Riyadh Region, 3712 sheep were examined [11].

Gene context of Myiasis

• The sclerocorneal surgical wound seems the most likely site of entrance of the parasite, and this would then be the first reported case of myiasis with no RPE tracking [12].
