猪病病理剖检诊断技术研究

要搞好猪病剖检诊断，应熟悉猪的正常组织器官，避免病理剖检时将正常组织器官误诊作病变组织器官，熟悉猪死亡后尸体的变化，避免把某些死后变化误认为是生前的病理变化，熟悉各种觉病理变化和各种猪病的特征病变，掌握正确的剖检诊断程序及方法，以确保剖检效率和发现有诊断价值的病变，剖检结果应结合病猪发病情况和外部检查情况，才能做出剖检诊断.

Nutrition, key factor to reduce environmental load from pig production

In different parts of Europe animal production is highly concentrated. Pig production generally is the main animal production activity in these areas. Main concerns of these large numbers of pigs are the amount of surplus nutrients in excreta and gaseous losses to the environment. Main nutrients of concern are N, P, and heavy metals and main gaseous losses of concern are ammonia, odour, and methane. Although losses are inevitable to a certain extent, nutrition seems to be a key factor in reducing these losses. Main nutritional strategies to reduce N and P excretions from pigs are: phase feeding (N, P), supplementation of limiting amino acids to the diet (N), and addition of phytase to the diet (P). Nutritional strategies to reduce heavy metals excretions from pigs are: finding alternative, natural, growth promoters that could replace Cu and Zn in the diet; using feedstuffs for the diet that are less contaminated with Cd. Main strategies to reduce ammonia emissions are: 1) lowering crude protein intake in combination with addition of limiting amino acids; 2) Shifting nitrogen excretion from urine to faeces by including fermentable carbohydrates in the diet; 3) lowering pH of urine by adding acidifying salts to the diet; 4) lowering the pH of faeces by inclusion of fermentable carbohydrates in the diet. These strategies proved to be independent from each other and effects are additive. By combining these strategies a total reduction of ammonia emission in growing-finishing pigs of 70% could be reached. Strategies to reduce odour emission are: 1) reducing protein fermentation by balancing available protein and fermentable carbohydrates in the large intestine; 2) Minimizing breakdown of absorbed sulphur amino acids. More studies are needed in this area of research, but results until now are very promising. A clear relationship exists between fermentable carbohydrates in the diet and methane emissions. This disadvantage should be considered when tackling ammonia emission by this strategy. It is concluded that there is a large potential to reduce environmental load within pig dense areas by nutritional means.

Main Drain virus as a cause of equine encephalomyelitis

Main Drain virus, which is thought to be transmitted normally among rabbits and various rodents by its natural vector, Culicoides variipennis, was isolated repeatedly from brain tissue of a sick horse from Sacramento County, California, and was implicated as the causative agent. Signs of illness were incoordination and ataxia, stiff neck, head pressing, inability to swallow, fever, and tachycardia.     

T-cell lymphoma in a wild Okinawa rail (Gallirallus okinawae)

The Okinawa rail (Gallirallus okinawae) is an endangered species that inhabits the northern part of Okinawa Main Island in southern Japan. A wild Okinawa rail was rescued from a road in Kunigami Village in Okinawa in October 2009. The bird subsequently died and underwent necropsy. Tumors were found in the liver, spleen and part of the small intestine. Microscopically, lymphoid neoplasm was confirmed in these tissues. The tumor cells were mainly positive for CD3 and CD8α by immunohistochemistry. No Marek's disease virus genes were detected by PCR of a liver tumor. This is the first report of T-cell lymphoma in the Okinawa rail.     

Sporadic cases and an outbreak of leptospirosis probably associated with recreational activities in rivers in the northern part of Okinawa Main Island

In the summer of 2003, sporadic cases and an outbreak of human leptospirosis probably related to recreation in rivers occurred in the northern part of Okinawa Main Island. Sixteen of 22 suspected cases were definitely diagnosed as leptospirosis by serological test or isolation. The infective leptospiral serovar in 14 cases was presumed to be Hebdomadis. Transmission was thought to occur by exposure to river water that was contaminated by the urine of infected animals. The findings indicate that recreation in rivers in this area is a significant risk factor for infection with leptospires.
