锡林郭勒盟草原莱姆病疫源地调查

本项研究于2000年5月—2001年5月从内蒙古锡林郭勒盟地区，不同草原景现带牛、羊体表和草地采集草原血蝉1800只，用直接荧光抗体法检查蜱带菌情况，带菌率为7.5%(6/80)。晴视野显微镜检查蜱带菌情况，带菌率为2%（2/100）；用间接荧光法进行血清流行病学调查，结果证实，调查点的牛和野鼠均存在莱姆病螺旋体感染，其感染率分别为10%和20%，都高于当地人群平均感染率（7.09%)，上述研究证实内蒙古锡林郭勒盟地区人畜及野生动物均有莱姆病螺旋体感染。     

诊断桑树黄化型萎缩病的新方法

本文探讨利用瑞氏染色法和旦尼氏染色法诊断桑树黄化型萎缩病的可能性。试验结果表明,用此方法,在病株枝条或主根的横切面上,韧皮部的病原寄生部位被染成兰色或青色,呈阳性反应,健株组织切片的韧皮部则不着色,呈阴性反应。可作为桑黄化型萎缩病病株的实验诊断手段。

对 5批兔病毒性出血症、多杀性巴氏杆菌病、产气荚膜梭菌病三联灭活疫苗进行了动物试验 ,结果表明该疫苗安全有效。近期效检对兔病毒性出血症的保护率为 1 0 0 % ,对兔多杀性巴氏杆菌病保护率为 92 % ,对产气荚膜梭菌病 (A)型保护率为 88%。在免疫期试验中 ,免疫 6个月后 ,对兔病毒性出血症保护率为 1 0 0 % ,对多杀性巴氏杆菌病的保护率为 79% ,对产气荚膜梭菌病 (A)型的保护率为 88%。在保存期试验中 ,4～ 8℃保存 1年仍有效。     

The Relationship Between Body Weight,Body Condition,and Survival in Cats with Heart Failure

Background: Obese people with heart failure have improved survival compared with their normal or underweight counterparts. The purpose of this study was to determine if there is a relationship between body weight or body condition and survival in cats with heart failure. Hypothesis: Body weight and body condition score (BCS) are predictors of survival in cats with heart failure. Animals: One‐hundred and one cats with heart failure (International Small Animal Cardiac Health Council Classes II, IIIa, or IIIb) evaluated between March 2007 and June 2009. Methods: Data regarding initial body weight and BCS, subsequent changes in body weight, and treatment were collected from records and compared with survival times. Results: Median initial body weight was 5.1 kg (range, 2.2–9.5 kg). Median BCS was 5 (range, 3–9). Of the 68 cats that were discharged from the hospital, median body weight change was 0.0 kg (range, ?2.6 to +2.3 kg). Survival time for all 101 cats was 93 days (0–811 days). Survival could be predicted using a model combining initial body weight (P= .02), body weight squared (P= .02), and survival to discharge (P < .001) with a resulting global P value for this model of P < .0001. Conclusions and Clinical Importance: Cats with the lowest and highest body weights had reduced survival times compared with those with body weights in the intermediate ranges, suggesting a U‐shaped relationship between body weight and survival. Additional research into the effects of body composition could help to determine optimal management of cats with heart failure.     

北京地区冷季型草坪草病害调查及防治

通过对北京及周边地区草坪病害调查,初步研究了草坪病害的主要种类、发生规律及危害程度.结果表明,对草坪破坏大、严重影响景观效果的病害种类有褐斑病、腐霉枯萎病、夏季斑枯病、镰刀菌枯萎病、锈病和蠕孢叶枯病.杀菌剂抑菌效果表明,甲基托布津、代森锰锌、杀毒矾、瑞毒霉和灭霉威在试验浓度范围内对4种病菌都有抑菌作用;种子包衣抑菌效果显示大部分包衣剂能够防止种子发生霉变,除镰刀菌外,种子包衣剂处理对各种病菌均有不同程度的抑制效果.
