introduction wound myiasis is one of the common types of myiasis that demonstrates obligatory parasitic behavior. case presentation a 62-year-old homeless man presented with an abnormally growing and ruptured neck mass containing worms. he had wound myiasis caused by the larva of lucilia sericata in his previously punctured neck. discussion lucilia sericata can cause both facultative and obliga...

introduction ophthalmomyiasis is a rare disorder that is caused by invasion of dipterous larvae to necrotic tissues. case presentation an 80-year-old woman with invasive basal cell carcinoma (bcc) presented anabnormal growth of worm in her eye. she had ophthalmomyiasis caused by lucilia sericata larva in here nucleated eye. l. sericata is common all over the temperate and tropical regions, main...

Parasitic infestations of the external eye are uncommon and more often prevalent in tropical and developing countries. We present three cases with ocular infestation caused by three different arthropods admitted to the ophthalmology department of a tertiary health care centre during two months. The first case was infected with the larvae of Oestrus ovis, the second case with Phthiriasis palpebr...

Parent-offspring conflict over clutch size may lead to siblicidal behavior between juveniles. In parasitoid wasps, selection for siblicide in small broods is predicted to produce a dearth of gregarious broods with few eggs. Here we document the clutch size distribution in the Bethylidae, a large family of aculeate parasitoids. Small gregarious clutches are the most common. Further data suggest ...

conclusions early diagnosis is required for the management of human myiasis. if we don’t properly recognize and treat ophthalmomyiasis, it can progress rapidly and can result in destruction of orbital tissues. the main treatment modality includes removal of the larvae and if necessary, surgical debridement. case presentation we describe a young male with wound and ocular myiasis due to lucilia ...

A widespread hair-loss syndrome (HLS) has affected Columbian black-tailed deer (Odocoileus hemionus columbianus) in western Oregon and Washington (USA) since 1996. In order to better characterize the condition, 21 HLS-affected black-tailed deer (BTD) were necropsied, and body condition, parasite burdens, and significant lesions were noted. All deer were in poor body condition, and at least 17 h...

The owners of 63 pruritic dogs were instructed to feed them a chicken hydrolysate diet exclusively for six weeks as part of diagnostic investigations into non-seasonal pruritus. Ectoparasitism and microbial infections were eliminated during the dietary trial. The dogs' skin lesions, gastrointestinal signs and frequency of defecation were assessed and scores for pruritus were assigned before the...

To consider the evolutionary origin of the ectoparasitic habit in the blowfly genus Lucilia (Diptera:Calliphoridae), phylogenetic analyses of mitochondrial DNA sequence data were performed for 10 species, including all the common Lucilia agents of myiasis, collected from Africa, Australasia, North America and Europe. Complementary genetic distance and parsimony analyses are used to consider int...
