Endometritis is considered a significant cause of infertility problems in dromedary camels. This study aimed to compare the efficacy of different treatment protocols for endometritis in dromedary camels under Abu Dhabi Emirates' conditions. A total of 112 dromedary she-camels with uterine infection were subjected to uterine swabbing for bacterial culture and received one of the following treatments: (i) uterine douching with lotagen every other day for three doses, (ii) single parenteral oxytetracycline injection, (iii) subcutaneous injection with ceftiofur for 5 days, or (vi) combined oxytetracycline-ceftiofur injection. The results showed that was the most isolated bacteria, followed by Streptococcus species. Treatment efficacy was ( < 0.05) higher in ceftiofur and oxytetracycline-ceftiofur protocols compared with lotagen and oxytetracycline protocols. The fertility indexes, services per conception and pregnancy rate, were improved in ceftiofur and mixed oxytetracycline plus ceftiofur protocols as the pregnancy rate was ( < 0.05) higher in those protocols compared with lotagen and oxytetracycline protocols (71.4 and 67.9% vs. 39.3 and 42.9%, respectively). On the other hand, the number of services per conception was significantly lower in ceftiofur and oxytetracycline-ceftiofur protocols (1.2 for each protocol) than in lotagen and oxytetracycline protocols (1.8 and 1.7, respectively). In conclusion, subcutaneous injection of 1 ml ceftiofur per 50 kg body mass for 5 days can be used as an efficient treatment for uterine infection in female dromedary camels caused by and Streptococcus species for improving their fertility indexes.
子宫内膜炎被认为是单峰骆驼不孕问题的一个重要原因。本研究旨在比较在阿联酋阿布扎比条件下，不同治疗方案对单峰骆驼子宫内膜炎的疗效。共有112头患有子宫感染的单峰母骆驼接受了子宫拭子细菌培养，并接受了以下治疗之一：（i）每隔一天用洛他根进行子宫灌洗，共三剂；（ii）单次肌肉注射土霉素；（iii）皮下注射头孢噻呋5天；或（iv）联合注射土霉素 - 头孢噻呋。结果显示，[此处原文缺失具体细菌名称]是最常分离出的细菌，其次是链球菌属。与洛他根和土霉素方案相比，头孢噻呋和土霉素 - 头孢噻呋方案的治疗效果更高（P < 0.05）。头孢噻呋和土霉素加头孢噻呋联合方案的繁殖指数、每次受孕配种次数和妊娠率均有所提高，因为这些方案的妊娠率（P < 0.05）高于洛他根和土霉素方案（分别为71.4%和67.9%，而洛他根和土霉素方案分别为39.3%和42.9%）。另一方面，头孢噻呋和土霉素 - 头孢噻呋方案的每次受孕配种次数（每个方案均为1.2次）显著低于洛他根和土霉素方案（分别为1.8次和1.7次）。总之，每50千克体重皮下注射1毫升头孢噻呋，持续5天，可作为治疗单峰母骆驼由[此处原文缺失具体细菌名称]和链球菌属引起的子宫感染、提高其繁殖指数的有效方法。
