羊传染性口膜炎的流行病学、临床症状、诊断及防治

羊在生长过程中感染性口膜炎症,主要原因是因为受副痘病毒感染,而导致的接触性传染病。这种传染性疾病往往在春秋两季经常发生,发病对象通常是在羔羊,因为其相对于成年羊来说更加容易受到感染。被副痘病毒感染的羊,在最开始的时候会形成红色的皮疹,然后会慢慢变化成脓疱,然后在脓疱破裂后会发生结痂,并会慢慢的干燥、脱皮、掉下,在严重的情况下,病羊的整个嘴巴变得发炎、口腔内部会发生溃烂,牙齿会一个个的掉落,以为这些原因,使得病羊难以采食,然后会变得非常的瘦弱,从而继发性感染出现,最终会导致病羊产生死亡。     

羊传染性脓包口膜炎的防治分析

羊的传染性脓包口膜炎在临床上很常见,属于多发性的疾病.最近患传染性脓包口膜炎的病羊特别多,这种疾病主要是口腔内部的粘膜发炎引起的炎症.造成这类疾病的主要原因是羊食入的饲料太粗糙,或者是饲料中含有其他杂物,例如麦芒、玻璃渣或者木屑等伤害到了口腔内部的粘膜,另外给羊服用了某些具有刺激性的高浓度的药物,也会造成口膜炎,因此必须及时有效的治疗.

鸡传染性法氏囊病的防治

自1988年发现并确诊首例鸡传染性法氏囊病以来,传染性法化囊病的发生就从来没有间断过，给养鸡生产带来了巨大的经济损失。近几年来，随着养殖户对该病的认识逐步提高，防治措施也不断加强，便该病的发生机率大大减少，但仍避免不了时有发生的情况。该病仍然是养鸡业生产中最常见、成胁最大的传染病之一。

Mycoplasma infections in farm animals: specific prevention of infectious (contagious) agalactia in the sheep and goat

The authors of this paper have produced live vaccine to cope with infectious agalactia in goat. The vaccine (culture) was used on 360, 924 goats kept on ajmaks in Bajanchongor and Gobi-Altaj, in 1986. The number of pathologically affected goats went down by a factor of 4.5, as compared to 1985. Mortality was reduced to one third. Abortions declined by a factor of 2.6 and infertility among goats by 1.6. The conclusion is that sheep of the Mongolian breed are not susceptible to infectious agalactia. Large-scale production tests of live cultures supported hopes for successful action on this infectious disease under Mongolian conditions.

Bacteriological investigation of infectious keratoconjunctivitis in Norwegian sheep

Contagious keratoconjunctivitis is a rather common disease in Norwegian sheep. Since the knowledge of its aetiology is limited, the present study was performed to determine the microorganisms involved. Local veterinarians throughout the country collected conjunctival swabs from both sick (n = 43) and healthy (n = 42) sheep on 15 farms with outbreaks of ovine keratoconjunctivitis, and further from healthy sheep (n = 50) on 17 farms not showing any signs of conjunctival disease. All samples were cultivated for bacteria and mycoplasma. Listeria monocytogenes was isolated from 3 cases (1%) in one single herd. Staphylococcus aureus (5%), Corynebacterium spp. (2%) and Escherichia coli (4%) were isolated only in herds with keratoconjunctivitis, but from both sick and healthy animals. Moraxella (Branhamella) ovis was isolated from 28% of sampled animals in affected herds and from 10% of sampled animals in healthy herds. The corresponding numbers for Moraxella spp. were 9%/12%, for Pseudomonas spp. 7%/8%, for Staphylococcus spp. 22//22%, for Bacillus spp. 12%/14%, for Micrococcus spp. 6%/2% and for Streptococcus/Enterococcus spp. 2%/2%. Mycoplasma conjunctivae was isolated from 16 animals with keratoconjunctivitis (37%) and from 3 animals without clinical signs (7%) in farms with keratoconjunctivitis. In farms without clinical signs of keratoconjunctivitis, M. conjunctivae was isolated in 4 animals (8%). To our knowledge, this is the first time M. conjunctivae has been isolated in Norway. Other predisposing agents found were Moraxella (Branhamella) ovis and Listeria monocytogenes. The etiological importance of different microorganisms in ovine keratoconjunctivitis seems to vary; some are probably only present as secondary invaders. Other possible causes of ovine keratoconjunctivitis in Norway, such as Chlamydia psittaci, remain to be investigated.
