What We Know about PRRS

猪繁殖和呼吸障碍综合征(Porcine Reproductive and Respira-tory Syndrome,PRRS),又称蓝耳病,是一种具有重要经济意义的猪病,它持续困扰着猪肉生产者和兽医,会成批地减少活猪存栏数,并给猪肉生产者带来重大经济损失.蓝耳病临床爆发的首次报道为美国在20世纪80年代后期,然而,该病的病原学或起因并不清楚.     

What Do We Know About Risk Factors for Infection in Humans with Toxoplasma gondii and How Can We Prevent Infections?

Fourteen case–control studies evaluating the importance of different risk factors for infection of humans with Toxoplasma gondii were identified. Surprisingly, up to two‐thirds of infections could not be explained by risk factors such as consuming raw or undercooked meat or poor kitchen hygiene. Few studies reported population attributable risk, and when reported, it was low. Protocols including questionnaires used for collecting data, age and socio‐economic groups studied, and sample sizes varied among studies. There is a need for carefully planned, case–control studies to identify sources of infection with T. gondii in humans. New risk factors, such as the manufacture of organic meat, and possible ways to sterilize meat to inactivate T. gondii tissue cysts are discussed.     

Laminitis in the geriatric horse.

There are few diseases that instill a comparable sense of doom in the mind of a treating veterinarian as laminitis. There is a feeling of cautious optimism when a horse with laminitis responds favorably to treatment. Although this optimism all too often proves false when treating laminitic patients, management of the patient afflicted with chronic laminitis can be rewarding. Through diligent and careful client communication and instruction, many geriatric patients with chronic laminitis can be maintained for years as comfortable companions, for light riding use, or as productive breeding animals.     

Laminitis in the horse: a review

Laminitis has been a recognized disease since early Greek and Roman times, but it is still bothering both practitioners and scientists. In the last decade a lot of new fundamental research has been done to elucidate the pathogenesis of laminitis. New insights into the pathogenesis, the predisposing factors (including nutritional overload, endotoxaemia, shock, management, etcetera), clinical and radiological signs, differential diagnosis, therapy, and prognosis of the disease are described. The data, however, are not always in agreement with each other, giving further proof of the complexity of the syndrome.
