| survey on the importance of mange in the aetiology of skin lesions in goats in peninsular malaysia. | a survey on mange mite infestations in the aetiology of skin lesions in goats in peninsular malaysia is described. skin lesions were observed in 25 (93%) of the 27 goat farms investigated. mange mites were found in 22 (88%) of these goat herds. chorioptes texanus was found in 20.7%, psoroptes cuniculi in 19.3%, sarcoptes scabiei in 18.6% and demodex canis var. caprae in 0.4% of the samples, taken from the skin lesions. thirteen cases of generalised manage were diagnosed, from which 9 were caused ... | 1994 | 7941034 |
| [further studies on parasitic arthropods of the elk alces alces in poland]. | in the northeastern part of poland, 239 elks (5% of the polish population) were examined and 7 species of ectoparasites were found. the most frequent included: lipoptena cervi (94%) and chorioptes texanus is new species in poland and it was noted at 50 sites from warmia and the mazurian lake district. | 1996 | 9012137 |
| genetic differentiation of mites of the genus chorioptes (acari: psoroptidae). | in an effort to clarify the species status of mites of the genus chorioptes the second internal transcribed spacer of the rrna gene was characterized in 14 isolates from cattle, horse, sheep and llama of different geographic origins. the genotypes segregated into two clearly separated groups of dna sequences. in addition, two phenotypes could be distinguished by the lengths of the outer opisthosomal setae of male adults which had previously been designated as chorioptes bovis and chorioptes texa ... | 1999 | 10399307 |
| chorioptic mange (acarina: psoroptidae) in domestic and wild ruminants in israel. | in a 20-year-survey, 9364 dairy cattle in 324 herds kept under a zero-grazing management, 1252 beef cattle in 46 herds grazing all the year round, 3347 sheep in 134 herds (only 26 are grazing herds), and 872 goats in 47 herds (only 20 are grazing) were examined. the mites collected from cattle were identified as chorioptes texanus only, and those from sheep, goats and gazelles were identified as c. bovis. chorioptic mange was not diagnozed in grazing beef cattle, ibexes and housed animals (as co ... | 1999 | 10668861 |
| the first outbreak of chorioptes texanus (acari: psoroptidae) infestation in a cattle farm in korea. | mites in the genus chorioptes cause a mild form of skin disease in both domestic and wild ruminants. in july 2006, dermatitis characterized by alopecia, marked lichenification, accumulation of crust, and fissuring was recognized in 14 out of 200 holstein dairy cattle raised in the cattle farm of the national institute of animal science in cheonan, republic of korea. skin lesions were distributed mainly over the tail base, and sacral and perineal regions. microscopic examinations of skin scraping ... | 2008 | 19127336 |
| chorioptes mites: re-evaluation of species integrity. | chorioptes mites (acari: psoroptidae) are non-burrowing agents of mange which parasitize a wide range of domesticated and wild ungulates. considerable historical confusion has surrounded the description and naming of the various species of chorioptes. here, the opisthosomal setae of male adult chorioptes mites from a range of host species and geographic locations were subjected to detailed analysis. discriminant analysis suggests the existence of three clear morphotypes. the first, chorioptes bo ... | 2011 | 21418262 |
| Molecular taxonomic relationships of Psoroptes and Chorioptes mites from China based on COI and 18S rDNA gene sequences. | In this present study, the mitochondrial DNA gene cytochrome coxidase subunit I (COI) and the small subunit ribosomal RNA (18S rDNA) gene were used to determine the taxonomic relationships of Psoroptes and Chorioptes mites from China. The neighbor-joining and maximum-parasimony approach were used to evaluate the evolutionary relatedness among different hosts in the genera Psoroptes and Chorioptes. Phylogenetic analysis showed that Psoroptes cuniculi and Psoroptes natalensis may be two different ... | 2011 | 21974946 |
| acaricidal activity of petroleum ether extracts from eupatorium adenophorum against the ectoparasitic cattle mite, chorioptes texanus. | in this study, we evaluated the acaricidal efficacy of extracts obtained from the plant eupatorium adenophorum against the common cattle mite chorioptes texanus. the results showed that 95% ethanol extracts at concentrations of 1.0, 0.5, and 0.25 g/ml (w/v) were highly toxic to c. texanus in vitro, killing 100% of mites in 4 h. similarly, petroleum ether extracts of e. adenophorum resulted in between 80 and 100% mortality of mites in vitro at concentrations of 0.1, 0.05, and 0.025 ml/ml (v/v) wi ... | 2014 | 24464273 |
