It affects over 200 species of freshwater and marine fish. Several species of <em>Mycobacterium</em> are responsible among them <em>Mycobacterium marinum</em> is the comment. It also affects humans when exposed to contaminated water. In fishes, the symptoms include eroded fins, body surface coated with heavy mucus, changing pigmentation, swelling of abdomen, ulcerative dermal necrosis, and scale loss. In humans, the infection is classified into three clinical groups. Type I is a self-limiting, verruca lesion. Type II is single or numerous subcutaneous granulomas in the presence or absence of ulceration. Type III is deep infections of the tenosynovium, bones, bursa, or joints, resulting in tenosynovitis, osteomyelitis, and septic arthritis. The diagnosis is made by Ziehl-Neelsen acid-fast staining, culture, biochemical reaction, and PCR being the most reliable approach. Piscine mycobacteriosis is treated by antibiotics and vaccination has been considered for its long-term prevention in order to reduce morbidity and mortality. Morgellons disease (MD) is a filamentous dermopathy in which lesions with strange filamentous inclusions appear out of nowhere. Furthermore, formication may accompany dermopathy. The identification of <em>Borrelia spirochetes</em> directly in Morgellons disease patient specimen is constant and repeatable when sensitive and precise detection techniques are utilized. It has been diagnosed by microscopy, histology and molecular diagnostic techniques which are highly sensitive and specific. Morgellons disease is still a myth therefore its treatment is evolving, up to date it has been treated symptomatically.展开更多

The purpose of this study is to assess the basis for efficacy and safety of using a novel fish derived acellular dermis (Kerecis Omega3 DuraTM). In an ovine model a craniotomy under general anaesthesia was performed. A defect was produced in the dural covering of approximately 1 × 2 cm and closed with an onlay technique, with Kerecis Omega3 Dura. The bone defect was covered with the bony flap and the overlying tissues closed in layers. At 2, 5, 8 and 11 weeks the sheep underwent MRI scanning followed by euthanasia, necropsy and histological assessment. MRI images taken at 2, 5, 8 and 11 weeks showed initially moderate inflammatory response, which diminished over time, and at 11 weeks no evidence of inflammation existed. There was evidence of cerebrospinal fluid leakage at no time point. Necropsy revealed some adhesions at 5 and 8 weeks, in particular at 5 weeks, but at 11 weeks there were no adhesions found. From 2 - 11 weeks, there was evidence of initially an inflammatory reaction followed by neodura formation at the defect site through cellular ingrowth and remodeling of the acellular fish skin. Histology showed a histiocytic foreign body reaction initially that subsided over time. As early as 8 weeks there was evidence of neodura formation and by 11 weeks there was a minimal inflammatory response with an intact neodura formed. In this pilot study the Kerecis Omega3 Dura patches performed in a safe and efficacious manner. This new material needs to be fully assessed and compared with other products that are currently on the market in a larger scale animal study.展开更多

Twenty ornamental fish species were identified in the coastal water bodies in this stretch. Some of them are already established as aquarium fishes and rest demand ornamental piscine status for their unique features and qualities. Some of the ornamental fish species of this area like Brachygobious sua, Gobipterus chuno, Badis badis and Brachydanio rario are endangered due to excessive degradation of local ecosystems. Special care should be taken so that they continue to exist. There are ample justifications to establish ornamental fish industry to support the unemployed youth of the area and protect the piscine biodiversity.展开更多
