Gastritis in Lake Tanganyika cichlids (Tropheus duboisii)

Necrotic and granulomatous gastritis is described in Lake Tanganyika cichlids. Clostridium hastiforme and flagellated protozoa were both associated with the reaction but the significance of either is unknown. Nevertheless, treatment of surviving fish with ampicillin was carried out and mortalities ceased. The possible involvement of an unsuitable diet as a predisposing factor is discussed.     

Stephanofilarial dermatitis in India

Four species of Stephanofilaria have been reported from India causing various forms of dermatitis in cattle, buffalo, goat and elephant. However, additional work is needed to establish their identity as separate species. The lesions appear to flare up following reinfection, while the application of a petroleum jelly alone reduces them. In vitro tests have shown organophosphorous compounds to possess stephanofilaricidal action in addition to their insecticidal activity. Aspects where further work is needed are indicated.     

鸡的坏疽性皮炎

坏疽性皮炎是最近变得严重起来的一种由致死性梭菌感染引起禽的疾病,主要危害幼鸡(3～7周龄)和快速生长的鸡,其特点是发病突然,死亡率急速上升,皮肤、皮下组织及皮下鸡肉中出现渗出性、气性和出血性病变。坏疽性皮炎曾被称为“坏死性皮炎”、“梭菌性皮炎”、“传染性皮炎”、“坏疽性蜂窝织炎”、“禽恶性水肿”、“气肿病”、“烂翅病”,以及有时所称的蓝翅病等等。此病首次报告于鸡,此后在鸡和蛋鸡报告了许多病例。坏疽性皮炎还报告发生于火鸡。目前,在最常见的与皮肤有关的疾病中,其重要性仅次于蜂窝织炎。虽然传统上认为坏疽性皮炎的发…

坏疽性皮炎--家禽的一种突发性疾病

坏疽性皮炎是养禽业最重要的突发性疾病之一,它可以危及肉鸡、种鸡和蛋鸡的正常生产,并引起急性死亡,给养禽业造成重大经济损失。据报道,近年来本病在世界范围的影响正逐渐增加,从而引起人们的普遍关注和重视。本病以患部皮肤及皮下结缔组织水肿、气肿及坏死为特征,患鸡通常以死亡而告终。皮肤的任何损伤给鸡舍环境中普遍存在的A型产气荚膜梭状芽孢杆菌或某些非梭状芽孢菌,如:金黄色葡萄球菌、大肠杆菌造成了入侵感染的机会,从而导致本病的发生。发病日龄多见于17d～20周龄。商品肉鸡在4～8周龄均有发生。本病的死亡率通常在1%～60%不等。…

Contact dermatitis

Allergic contact dermatitis and irritant contact dermatitis in the small animal may result in clinical lesions with similar anatomical locations. Allergic contact dermatitis is generally noted in ventral and lightly haired regions as a papular, erythematous, and sometimes vesicular dermatitis. It is intensely pruritic and is the result of many months (and usually years) of exposure to the contact allergen. Total avoidance of the allergenic substance is the only successful long-term management. Irritant contact dermatitis occurs when an irritating substance is applied to the skin. It is a sequela that would occur in the majority of a population having contact with the compound. It is generally more painful than pruritic. Removal of the irritant will permit resolution of the signs.
