雏鸡白痢杆菌病的诊治

鸡白痢是由鸡白痢沙门氏菌引起的鸡的传染病。雏鸡通常表现为急性全身性感染,病雏鸡以精神倦怠、白痢为特征,成鸡则表现为局部和慢性感染或隐性感染。2005年5月18日奇台县古城乡果园二队个体养殖户陈某饲养的肉仔鸡8日龄发生了以拉白色稀粪为主要特征的传染病,经采取措施,到12日龄时基本控制住病情。现报告如下:1发病情况2005年5月10日该专业户从乌鲁木齐市养禽场购进肉用仔鸡2000羽。发病前为阴雨天气,鸡舍内温度有所下降,6日龄时见几只雏鸡拉白色稀粪。2临床症状雏鸡群内部分雏鸡出现精神沉郁,低头缩颈,闭目嗜睡,翅下垂,羽毛松乱,食欲下降…

乌桕水提液对人工感染鸡白痢病的疗效研究

鸡白痢是由鸡白痢沙门氏菌引起的家禽疾病,该病主要侵害雏鸡,其发病率和死亡率都较高,死亡率可达40%～6O%,甚至100%,常造成大批雏鸡死亡,主要与年龄、易感性、营养、管理和感染程度不同等因素相关[1],给生产规模和管理水平低、环境污染严重的农村是小养殖户带来较大的经济损失.

种鸡场鸡白痢病的综合防治

鸡白痢是由鸡白痢沙门氏杆菌引起的鸡和火鸡等禽类的传染病。要防治本病,必须从种鸡抓起,有计划地进行鸡白痢检疫,淘汰阳性鸡,切断横向传播和垂直传播途径,结合综合防治措施,有效控制此病的发生。1种蛋消毒1.1种鸡场要建立严格的种蛋消毒措施。每栋种鸡舍要设种蛋消毒柜,饲养员必须按规定每2h集蛋一次,然后检出脏蛋、破蛋、畸形蛋后,将种蛋大头向上码放在蛋盘里,放入种蛋消毒柜,用28ml/m3福尔马林熏蒸30min。1.2种蛋送入孵化厅后,按上述方法再次消毒后,或入孵,或送种蛋库保存,保存时间不要超过一周。特别在炎热的夏季,种蛋要低温(18～25℃)…     

Efficacy of alpha-cyclodextrin against experimental cryptosporidiosis in neonatal goats

The efficacy of orally administered tablets containing alpha-cyclodextrin, an excipient used in the pharmaceutical industry with demonstrated anticryptosporidial activity in vitro and in neonatal mice, was evaluated in neonatal goat kids. The formulation was evaluated for hardness and was subjected to in vitro drug release studies. Twenty goat kids were orally inoculated with 10(6) oocysts of C. parvum within the first 6 days of age. Half of the animals were treated by oral administration of four tablets of alpha-cyclodextrin/day (500 mg/kg of body weight) for six consecutive days, the treatment beginning on the day of inoculation. Infection was monitored by daily examination of faecal samples from the first day to 25 days post-inoculation. The criteria studied in evaluating efficacy were: oocyst shedding, presence of diarrhoea and weight gain at 15 and 25 days post-inoculation. alpha-cyclodextrin was effective when given at the beginning of infection: there was a longer pre-patent period, a reduction in the patent period and a decrease in the intensity of infection, these differences being statistically significant (P < 0.05) compared with untreated neonatal kids. Moreover, except in one animal, the diarrhoea was prevented in infected neonatal kids. Animals from both groups increased the body weight and no significant differences were seen between the two groups.     

Efficacy of a bivalent vaccine against Marek's disease

A bivalent vaccine was prepared by combining inactivated Marek's disease virus and turkey herpesvirus. The efficacy of this vaccine, compared to turkey herpesvirus and inactivated Marek's disease virus separately, was studied in unsexed White Leghorn chicks which were vaccinated at one day old and then challenged at 21 days old with fowl blood infected with virulent Marek's disease virus. The bivalent vaccine appreciably delayed mortality resulting from Marek's disease and elicited the highest protective efficacy as judged on the basis of Marek's disease-specific mortality and percentage occurrence of lesions. The occurrence, extent and severity of gross lymphomas and microscopic lymphoproliferative lesions in various organs of the bivalent vaccinated birds were less than in the other challenged groups. In addition, the level of viraemia remained consistently and significantly lower in the bivalent vaccinated birds.
