| demodex injai: a new species of hair follicle mite (acari: demodecidae) from the domestic dog (canidae). | demondex injai sp. nov. is described from the hair follicles of a domestic dog in columbus, oh in october 1996. the mites occupy follicles from the orifice down to and into the sebaceous glands. the individual host may harbor both this new species and d. canis. a comparison of these two species is provided for identification purposes. | 2003 | 12693841 |
| demodex injai infestation and dorsal greasy skin and hair in eight wirehaired fox terrier dogs. | demodex injai mites were detected on trichoscopic examinations and/or deep skin scrapings in eight wirehaired fox terrier dogs with dorsal greasy skin and hair. histological examination performed in five dogs revealed marked sebaceous gland hyperplasia with lympho-plasmacytic periadnexal dermatitis in all of them. one mite section was observed in one patient. seven dogs were parasitologically cured after 2 to 7 months of oral ivermectin treatment. greasy skin and hair resolved in four dogs, was ... | 2009 | 19659538 |
| prevalence of demodex canis-positive healthy dogs at trichoscopic examination. | demodex canis is thought to be present in small numbers in the skin of most healthy dogs; however, available data on the prevalence of normal dogs harbouring d. canis are scarce. the purpose of this study was to investigate, using microscopic examination of plucked hairs, the prevalence of healthy dogs harbouring d. canis. seventy-eight clinically healthy dogs with no history of dermatological problems and clinically normal skin and hair coat were included in the study. five areas (perioral skin ... | 2010 | 19706007 |
| phylogenetic analysis of demodex caprae based on mitochondrial 16s rdna sequence. | demodex caprae infests the hair follicles and sebaceous glands of goats worldwide, which not only seriously impairs goat farming, but also causes a big economic loss. however, there are few reports on the dna level of d. caprae. to reveal the taxonomic position of d. caprae within the genus demodex, the present study conducted phylogenetic analysis of d. caprae based on mt16s rdna sequence data. d. caprae adults and eggs were obtained from a skin nodule of the goat suffering demodicidosis. the m ... | 2013 | 23996126 |
| molecular study on three morphotypes of demodex mites (acarina: demodicidae) from dogs. | canine demodicosis is a severe and highly prevalent dermatologic disease in dogs. pet dogs can be affected by three recognized demodex species that can produce clinical effects. in this paper, three morphological types of demodex mites have been isolated from spanish dogs. a complete morphobiometrical study of each one has been carried out. morphological and biometrical studies revealed three closely related populations with some distinctive characteristics and could be identified as demodex can ... | 2012 | 22895570 |
| phylogenetic relationships and new genetic tools for the detection and discrimination of the three feline demodex mites. | two feline demodex mite species have been described as causative agents of feline demodicosis, until recently a third species was detected. we provide an updated analysis on the phylogenetic relationship of demodex mites. in addition, we present the first qpcr assay for the detection and differentiation of all three feline mite species in a single reaction. specimen of demodex cati, demodex gatoi, and the recently discovered third species were collected from skin scrapings and fecal flotation fo ... | 2015 | 25468382 |
| development of a pcr technique specific for demodex injai in biological specimens. | the identification of demodex injai as a second demodex species of dog opened new questions and challenges in the understanding on the demodex-host relationships. in this paper, we describe the development of a conventional pcr technique based on published genome sequences of d. injai from genbank that specifically detects dna from d. injai. this technique amplifies a 238-bp fragment corresponding to a region of the mitochondrial 16s rdna of d. injai. the pcr was positive in dna samples obtained ... | 2013 | 23851729 |
| pcr amplification and dna sequencing of demodex injai from otic secretions of a dog. | the identification of demodex mites from dogs is usually based on morphology and location. mites with uncharacteristic features or from unusual locations, hosts or disease manifestations could represent new species not previously described; however, this is difficult to determine based on morphology alone. | 2013 | 23470180 |
| phylogenetic relationships in three species of canine demodex mite based on partial sequences of mitochondrial 16s rdna. | the historical classification of demodex mites has been based on their hosts and morphological features. genome sequencing has proved to be a very effective taxonomic tool in phylogenetic studies and has been applied in the classification of demodex. mitochondrial 16s rdna has been demonstrated to be an especially useful marker to establish phylogenetic relationships. | 2012 | 23140317 |
