猪多杀性巴氏杆菌的分离鉴定及生物学特性研究

用PCR方法配合生化鉴定，从有肺炎症状猪的肺脏及进行性萎缩性鼻炎(Progressive atrophic rhinitis，PAR)症状猪的鼻拭子中分离出66株多杀性巴氏杆菌(Pasteurella multocida，Pm)。然后做了药敏试验，并用PCR方法对这66株Pm进行分型及毒素基因的检测，用豚鼠皮肤坏死试验及小鼠致死试验对产毒素多杀性巴氏杆菌(Toxigenie Pasteurella multocida，T^ Pm)进一步鉴定。结果显示PCR鉴定与生化鉴定Pm结果完全一致；PCR分型表明有46株为D型Pm，18株为A型：Pm，1株为B型Pm，1株无法定型；有8株用PcR检测为T^ Pm；豚鼠皮肤坏死试验及小鼠致死试验对这8株T^ Pm的进一步鉴定也表明均为产毒素菌株。所鉴定的8株T^ Pm都为D型，都分离于有严重PAR症状的猪。     

复方中草药"毒菌杀"对禽大肠杆菌及鸡白痢沙门氏菌的体外抑菌试验

观察了复方中草药“毒菌杀”的安全性及其对禽大肠杆菌及鸡白痢沙门氏菌的体外抑菌情况。结果发现“毒菌杀”安全性高，组成“毒菌杀”的各单味中药及其合剂对大肠杆菌的最低抑菌浓度MIC(g/mL)分别为板蓝根0．05、穿心莲0．05、黄芪0．025、黄柏0．05、柴胡0．05、生地0．05、甘草0．05、当归0．025，“毒菌杀”方剂为0．05；对沙门氏菌的MIC分别为板蓝根0．05、穿心莲0．025、黄芪0．025、黄柏0．05、柴胡0．025、生地0．05、甘草0．025、当归0．05，“毒菌杀”方剂为0．025；而牛胆汁对这两种致病菌的最低抑菌浓度分别为2％和1％。说明“毒菌杀”方剂对大肠杆菌、沙门氏菌具有明显的抑制作用。     

中西结合防治仔猪黄痢

仔猪黄痢又称为大肠杆菌病，主要由致病性大肠杆菌的某些血清型，如08、060、015、0141等感染而引起产后仔猪的一种急性传染病，临床上主要以腹泻、脱水和死亡率高为特征，临床对策主要以中西医结合，母仔同时治疗，收到了一定效果。

Acupuncture and traditional Chinese veterinary medicine for treatment of a mare with rectal paralysis

An 8‐year‐old Appaloosa mare with rectal paralysis due to a cosmetic ethanol ‘tail block’ was treated with traditional Chinese veterinary medicine treatments including acupuncture and herbal medicine. Her rectal and tail tone gradually improved after the treatment. At 4 months after initial presentation, the mare was able to produce faecal piles on a regular basis, and manual evacuations were no longer needed. Significant improvement was within 30 days of beginning treatment. At 8 months, the owner indicated that the mare had normal defaecation, was able to swish the tail from side to side and lift the tail to urinate, and had no evidence of straining to defaecate or colic.     

Investigation of Clinical Medicine for Treating Cows Endometritis in Baotou Area

In 4 dairy farms located in Baotou area, clinical medicine investigation and drug resistance of pathogenic bacteria were conducted, and then curative effects of different treatment methods were analyzed.Epidemic materials were collected from diary cows infected by endometritis, from which pathogenic bacteria were isolated using conventional microbiology technologies.Broth microdilution method was used to detect the sensitivity and resistance of pathogenic bacteria to antibiotics commonly used in clinic.On this basis, the sensitive drugs were used to treat mastitis or endometritis, the clinical curative effect of traditional treatment group was compared with that of therapeutic test group.The result of traditional treatment group showed 13 antibiotics were used to treat 160 cases of endometritis, florfenicol was most effective, penicillin was most ineffective.The results of therapeutic test group showed that Staphylococcus aureus, Escherichia coli and Streptococcus were the main pathogenic bacteria of endometritis, which were sensitive to gentamicin and cefalotin, etc.The results of statistical analysis showed that the curative effect of therapeutic test group was extremely significantly different from that of traditional treatment group(P<0.01).Sensitive drugs screened by drug sensitive test could be used to target therapy, and obtain satisfied curative effect.Moreover, this approach could avoid antibiotic abuse.     

规模化养殖场群体动物中草药服用方法的改进及其应用

利用中草药防治动物疾病已经成为养殖业研究的重要课题，但对动物服用中草药的难度较大，该文改进了传统的人工胃管灌服方法的缺陷，采用将中草药与精料共煮后饲喂，方法简便、价格低廉、节省人力，对规模化养殖场群体动物的中草药应用具有良好的推广价值。
