An epizootic of sarcoptic mange in coyotes from south Texas, Canis latrans , was studied over a 7-yr period, 1975 through 1981. From a four-county area centered in Webb County, Texas the epizootic radiated centrifugally to include a 27-county area. The disease progressed from initial, scabby encrustations on the ischium and fore and hind legs to severe, thickened, slate-gray hyperkeratotic lesi...

The mite Sarcoptes scabiei causes sarcoptic mange, or scabies, a disease that affects both animals and humans worldwide. Our interest in S. scabiei led us to further characterise a glutathione S-transferase. This multifunctional enzyme is a target for vaccine and drug development in several parasitic diseases. The S. scabiei glutathione S-transferase open reading frame reported here is 684 nucl...

Sanguinarine (1) and chelerythrine (2) are two quaternary benzo[c]phenanthridine alkaloids (QBAs). Eighteen derivatives of 1 and 2 were synthesized by modification of C=N(+) bond and evaluated for their in vitro acaricidal activity against Psoroptes cuniculi, a mange mite. A new method was developed to prepare 6-alkoxy dihydro derivatives of 1 and 2 (1a-e, 2a-e). Among all the compounds, only 6...

Lesions resembling knemidokoptic mange on the feet and tarsometatarsi of two Hawai'i' Amakihi (Hemignathus virens) were observed while the researchers were mist-netting wild passerines at Manuka Natural Area Reserve on the island of Hawai'i between 14 June 2007 and 19 June 2007. During subsequent mist-netting from September 2007 through February 2008, we found 26% (7/27) of the Hawai'i' Amakihi...

A retrospective study was performed on potbellied pigs with skin disease over a 22-year period. Thirteen of 190 pigs (7%) were examined by the Dermatology Service. Three different dermatoses were diagnosed: (1) sarcoptic mange, (2) yeast dermatitis of the eyelids (blepharitis) and periocular skin, and (3) presumed ichthyosis. Sarcoptic mange was cured with ivermectin injections. Yeast dermatiti...

Chorioptic mange caused by Chorioptes bovis is a common pruritic skin condition of the horse. This surface-browsing parasite usually affects the lower legs (leg mange) but can present as a generalized skin disease. Numerous anecdotal reports exist in the literature about the benefit of lime sulphur as a treatment for surface ectoparasites in the horse. This report studies the use of lime sulphu...

A total of 20 stray dogs were collected from Dinajpur district, Bangladesh from the period of March, 2009 to February, 2010 for investigating the prevalence and pathology of demodectic mange in stray dogs. The experiment was based on direct examination of the skin, skin scrapings and histopathological examination. The overall prevalence of demodectic mange was found 65% in stray dogs. The stray...

Rates of encounters between humans and wildlife are increasing in cities around the world, especially when wildlife overlap with people in time, space and resources. Coyotes (Canis latrans) can make use of anthropogenic resources and reported rates of conflict have increased in cities across North America. This increase may be linked to individual differences in the use of human food and develo...
