骆驼科动物的生殖损失是由于不育、妊娠损失、乳房疾病和各种传染病引起的新生儿死亡。子宫感染和流产是骆驼科兽医实践中的主要投诉。盆腔炎和子宫炎的主要感染菌是大肠杆菌。大肠杆菌和马链球菌动物亚种。在某些地区，传染病导致的流产率从10%到70%以上不等。钩端螺旋体病、弓形体病和衣原体病已被诊断为美洲驼和羊驼流产的主要原因。在中东和非洲的骆驼中，布鲁氏菌病和锥虫病是传染性流产的主要原因。乳房炎在南美骆驼科动物中是罕见的。骆驼亚临床乳房感染的患病率在产奶骆驼中可达到非常高的比例。乳房感染主要由无乳链球菌和金黄色葡萄球菌引起。新生儿死亡主要是由于被动转移失败和暴露于E.大肠杆菌、轮状病毒、冠状病毒、球虫和沙门氏菌。本文综述了导致生殖损失的病因、发病机制、主要危险因素及防治对策。
Reproductive losses in camelids are due to infertility, pregnancy loss, udder diseases and neonatal mortality caused by a variety of infectious diseases. Uterine infection and abortion represent the major complaint in camelid veterinary practice. The major infectious organisms in endometritis and metritis are E. coli and Streptococcus equi subspecies zooepidemicus. Abortion rates due to infectious diseases vary from 10% to more than 70% in some areas. Leptospirosis, toxoplasmosis and chlamydiosis have been diagnosed as the major causes of abortion in llamas and alpacas. In camels, brucellosis and trypanosomiasis represent the major causes of infectious abortion in the Middle East and Africa. Mastitis is rare in South American camelids. The prevalence of subclinical udder infection in camels can reach very high proportions in dairy camels. Udder infections are primarily due to Streptococcus agalactiae and Staphylococcus aureus. Neonatal mortality is primarily due to diarrhea following failure of passive transfer and exposure to E. coli, rotavirus, coronavirus, Coccidia and Salmonella. This paper reviews the etio-pathogenesis of these causes of reproductive losses, as well as the major risk factors and strategies to prevent their occurrence.
