Background: Eczema is one of the most widely spread inflammatory skin disorders contact dermatitis is an eczematous dermatitis that is produced as a result of contact with a substance in the environment. The substance can act as an irritant or allergen. Every country has allergen particular to itself. Objective: Determining the frequency of skin allergens in patients with contact dermatitis in ...

BACKGROUND About 10 to 20% of children in West European countries have atopic dermatitis (AD), often as part of the atopic syndrome. The full atopic syndrome also consists of allergic asthma, allergic rhinitis and food allergy. Treatment approaches for atopic dermatitis and asthma include intermittent anti-inflammatory therapy with corticosteroids, health education and self-management training....

BACKGROUND Digital Dermatitis (DD) is a common disease of dairy cows, the pathogenesis of which is still not clear. This study examined some host responses associated with the typical lesions, in an attempt to further elucidate the pathogenesis of the disease. Twenty four samples representing the 5 different clinical stages of DD (M0-M4) were collected from slaughtered cattle for histopathologi...

Bovine Digital Dermatitis (DD) is a leading cause of lameness in dairy cattle. DD is reportedly increasing in prevalence in beef cattle feedlots of the US. The exact etiologic agent(s) responsible for the disease have yet to be determined. Multiple studies have demonstrated the presence of a variety of Treponema spp. within lesions. Attempts to reproduce clinically relevant disease using pure c...

Background: Atopic dermatitis is a chronic, recurrent inflammation of the skin, accompanied by severe pruritus. Immune system dysregulation and skin barrier defects are associated with the abnormalities in atopic dermatitis. Myriad pieces of evidence have pointed to the major roles of LL-37 and interleukin-31 (IL31)in atopic dermatitis. The studies on atopic dermatitis are still limited i...

The term autoallergy denotes autoimmunity accompanying an atopic disease, with antigen-specific IgE as a hallmark. This phenomenon is discussed to contribute to a chronification of the disease and to shape the immune response in chronic atopic dermatitis (AD). In this review, we highlight recent insights into the autoallergic inflammation in AD. Different mechanisms underlying the allergenicity...

This study used a PCR-based approach targeting 16S rRNA gene fragments to determine the occurrence and association of the three bovine digital dermatitis (BDD) treponeme phylogroups within lesions found in cattle from the United Kingdom. Examination of 51 BDD lesions collected from infected cattle across the United Kingdom revealed that BDD treponeme group 1 (Treponema medium/Treponema vincenti...

This study investigated the relationship between flock health and Campylobacter infection of housed commercial broilers in Great Britain. Thirty ceca were collected at slaughter from batches of broilers from 789 flocks, at either full or partial depopulation, between December 2003 and March 2006 and examined individually for Campylobacter by direct plating onto selective media. Management and h...

Context Contagious ovine digital dermatitis (CODD) is related to bovine digital dermatitis, both being strongly associated with the pathogenic treponemes: Treponema medium, Treponema phagedenis and Treponema pedis. Other Treponema species-associated diseases with distinct clinical presentations have also been identified in goats and wild elk. In sheep, other causes of infectious lameness are al...

The milk yields of 1824 cows were used to investigate the effect of lesion-specific causes of lameness, based on farmer treatment and diagnosis of lame cows, on milk yield. A three-level hierarchical model of repeated test day yields within cows within herds was used to investigate the impact of lesion-specific causes of lameness (sole ulcer, white line disease, digital dermatitis and other cau...
