Epizootics of scaly leg disease caused by infection with the submacroscopic mite Knemidokoptes jamaicensis (Acari: Knemidokoptidae) in migratory American robins (Turdus migratorius) from a residential area of Tulsa (Oklahoma, USA) are documented during the winters (December through February) of 1993-94 and 1994-95. Estimates of 60 to > 80% of the birds in several different flights arriving in t...

The present study was conducted on 280 Egyptian buffaloes (Bubalis bubalus) during the period from June 2008 to July 2009. These animals belong to different villages in Assiut Governorate, Upper Egypt. The age of these animals ranged from less than one year to above eight years old. Examination of diseased animals revealed that they suffered from itching, loss of patches of hair in different re...

Parasitism has both direct and indirect effects on hosts. Indirect effects (such as behavioural changes) may be common, although are often poorly described. This study examined sarcoptic mange (caused by the mite Sarcoptes scabiei) in the common wombat (Vombatus ursinus), a species that shows severe symptoms of infection and often causes mortality. Wombats showed alterations to above ground beh...

Landscape epidemiology provides a valuable framework to interpret, predict, and manage spatiotemporal patterns of disease. Yet, owing the difficulty detecting pathogen occurrence in free-ranging wildlife, disentangling factors driving disease dynamics remains considerable challenge, particularly at fine spatial scales. Here, we investigated fine-scale landscape sarcoptic mange—a visually appare...

From November of 1994 to June of 1996 an epizootic of mange, probably caused by the mite Notoedres cati, occurred in white-nosed coatis (Nasua narica) in the tropical dry forests of the Chamela-Cuixmala Biosphere Reserve in western Mexico. A monitoring scheme to determine the extent and severity of the epizootic within coatis was implemented. Trapping periods and transects were conducted for 2 ...

Parasites collected from free-ranging black bears, Ursus americanus, in northern Wisconsin included Dermacentor variabilis, D. albipictus, Ixodes scapularis, Demodex sp., Trichodectes pinguis euarctidos, Baylisascaris transfuga and Dirofilaria ursi. Mange, possibly caused by the Demodex sp., also was observed. Dental caries were common and periodontal disease was observed in one animal.

Ovine psoroptic mange or sheep scab (also known by the descriptive names of belt, shab, tag or rubbers) is said to be one of the earliest known ectoparasitic infections. Sheep scab has been known since ancient times. It was known to Moses and has been documented by Cato, Virgil, Pleno and Columnella and (apparently) is referred to in the Bible (Leveticus XXII, 22). Although the Arabs were aware...

BACKGROUND Scabies caused by Sarcoptes scabiei is a widespread but a neglected tropical zoonosis. In this study, we characterised a S. scabiei thioredoxin peroxidase (SsTPx) and evaluated a recombinant SsTPx as a diagnostic antigen in rabbits. METHODS The open reading frame of the gene encoding SsTPx-2 was amplified and the recombinant protein was expressed in Escherichia coli cells and purif...

DEMODEX – THE MITES In the dog, the most common species of Demodex is Demodex canis. More recently, Demodex injai and the short tailed demodex, Demodex cornei have been identified. Demodex canis is a “cigar-bodied” mite measuring170-225 microns, and is transferred from the bitch to the suckling puppy within the first 3 days of life. It is considered a commensal organism of dogs and only becomes...

Mange is a contagious skin disease affecting various groups of animals. Psoroptic mange severe condition farm animals; it highly and responsible for huge economic losses in many Infestation with Psoroptes has been reported all over the world animals, but none ever swine. A male weaner large white breed pig age 3 months weighing 10kg was presented lesions areas alopecia during routine visit by h...
