Treatment of gastric ulceration in 10 standardbred racehorses with a pectin-lecithin complex     

Ferrucci F  Zucca E  Croci C  Di Fabio V  Ferro E 《The Veterinary record》2003,152(22):679-681

The severity of the erosive and ulcerative lesions of the squamous gastric mucosa in 10 standardbred racehorses in training was classified according to a standard scoring system. Each horse was then treated orally for 30 days with 50 g/100 kg bodyweight daily of a pectin-lecithin complex mixed into the feed. At the end of the period of treatment, the gastric lesions were re-evaluated gastroscopically and the scores were compared with those assigned at the previous evaluation. In three of the horses the gastric ulcerations had healed completely, and in six others the lesions had improved significantly.  相似文献

纪英卓  罗光彬  白文林  孙明亮  韩迪  曹亮 《吉林畜牧兽医》2006,27(10):7-9

本试验以辽宁绒山羊和内蒙古绒山羊为实验动物,采用PCR-RFLP技术对-酪蛋白基因(CSN3)片段的Ⅰ的酶切多态性进行分析,结果表明:辽宁绒山羊和内蒙古绒山羊2个山羊群体中均存在CSN3基因Ⅰ酶切位点的多态性,且均有A、B两个等位基因。辽宁绒山羊群体等位基因A和B的基因频率分别为0.46和0.54;内蒙古绒山羊群体中等位基因A和B的基因频率分别为0.31和0.69。CSN3基因Ⅰ酶切位点的基因型分布在辽宁绒山羊群体中极显著偏离Hardy-Weinberg平衡定理(<0.01),在内蒙古绒山羊群体中符合Hardy-Weinberg平衡定理(>0.05),但两个群体间存在显著差异(<0.01)。  相似文献   

Control and monitoring: monitoring and eradication of sharka in south-east Italy over 15 years

When the first foci of sharka were discovered in Puglia region (south-east Italy) in the late 1980s, the regional agricultural authorities launched a programme for Plum pox virus (PPV) monitoring and disease eradication. The infecting virus strain was identified as PPV-D. From 1989 to 1993, a strong eradication campaign was successfully carried out involving 13 plum and 2 apricot orchards with different levels of infection. During 1994–2000, besides plum, apricot and peach, monitoring was extended to sweet cherry. At that time, surveys and testing did not reveal any new PPV focus, but the eradication of infected trees continued in a couple of orchards. In 2001–05, particular attention was paid to peach, as devastating PPV-M outbreaks had developed in other areas of the country. A new PPV focus was found in apricot, caused by PPV-Rec, which was promptly eradicated. In the following two years, surveys in the once infected orchard and surrounding peach plantings did not detect any virus spread. The endeavour has taken 15 years making this PPV monitoring and eradication programme the longest in Italy. Its overall results indicate that the fruit tree industry in Puglia region can now be regarded as essentially PPV-free.  相似文献

Validation of RT‐PCR Assays for Molecular Characterization of Porcine Teschoviruses and Enteroviruses     

G. La Rosa  M. Muscillo  A. Di Grazia  S. Fontana  M. Iaconelli  M. Tollis 《Zoonoses and public health》2006,53(6):257-265

Porcine enteroviruses (PEVs) and teschoviruses (PTVs) are described as causative agents of neurological disorders, fertility disorders and dermal lesions of swine. Difficulties in the serological detection of these viruses may lead to a significant underestimation of infections with clinical symptoms. With the recent availability of genome sequence data for all the serotypes, molecular diagnosis is a possibility. The present study describes a new approach to molecular ‘serotyping’ of PTVs and PEV‐B viruses, involving the amplification and sequencing of a genomic fragment of the VP1 coding region. A molecular characterization of Italian entero‐teschovirus isolates was performed using a set of previously published and newly designed polymerase chain reaction primers. A total of 33 porcine isolates and 10 reference strains were analysed. Porcine enterovirus‐B samples were first diagnosed as positive for enterovirus by amplification of the 5′‐non‐translated region. Samples were then typed by amplification and sequencing of a portion of the VP1 coding region. Porcine enterovirus‐A and PTVs were detected by a published assay in the 5′‐NC region that allows them to be differentiated according to the size of amplification product, using the same set of primers. For serotype characterization of PTV, we evaluated four different regions: the N terminus of the capsid protein VP2, the region encoding for RNA‐dependent RNA polymerase, and the capsid VP1 and VP4 regions. The newly designed primers in the VP1 region was proved to be broad in range and suitable for serotype assessment and therefore constitute a useful diagnostic tool for molecular diagnosis of porcine teschovirus/enterovirus strains and for the study of molecular epidemiology and evolution of these viruses.  相似文献
