This study describes the clinical presentation of ruminal and reticular foreign body syndrome (RRFBS), and evaluates the effect of mineral deficiency on its occurrence in dromedary camels. Thirty dromedary camels were divided into two groups. Group 1 (control) included 10 apparently healthy she-camels. Group 2 consisted of twenty dromedary camels diagnosed with RRFBS on the basis of clinical, ultrasonographic, hematological, and biochemical examinations. Clinical findings showed decreased appetite and milk yield, tympany, and gradual body weight loss. Ultrasonographic examinations revealed the presence of hyperechoic material with variable degrees of shadowing. Hematological evaluation showed a significant (P<0.05) decrease of the total erythrocyte and lymphocyte count and a significant increase of neutrophils in the camels with RRFBS compared to the controls. Biochemical tests showed a significant elevation in the activity of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), creatine kinase (CK), glucose, creatinine, and blood urea nitrogen and a significant decrease of sodium, chloride, potassium, cobalt, iron, and selenium in the camels with RRFBS compared to the controls. Rumenotomy was performed on the 20 camels as a surgical intervention for treating the RRFBS. By the 6th month postoperatively, all surgically treated camels had completely recovered except for one with tympany and slight swelling in situ. In conclusion, trace element deficiency might play an important role in the occurrence of foreign body ingestion syndrome in dromedary camels. Moreover, clinical, ultrasonographic, hematological, and biochemical examinations are considered as tools assisting in the accurate diagnosis, prognosis, and treatment stratagem for RRFBS in camels.
本研究描述了反刍和网状外国物体综合征(RRFBS)的临床特征,并评估了矿物质缺乏对其在单峰驼中发生的影响。将 30 峰单峰驼分为两组。第 1 组(对照组)包括 10 只明显健康的母驼。第 2 组由 20 只被诊断为 RRFBS 的单峰驼组成,其诊断依据是临床、超声、血液学和生化学检查。临床发现表现为食欲和产奶量下降、鼓气和逐渐体重减轻。超声检查显示存在不同程度阴影的高回声物质。血液学评估显示,与对照组相比,患有 RRFBS 的骆驼的总红细胞和淋巴细胞计数显著(P<0.05)减少,中性粒细胞显著增加。生化试验显示,患有 RRFBS 的骆驼的血清天冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)、碱性磷酸酶(ALP)、γ-谷氨酰转移酶(GGT)、肌酸激酶(CK)、葡萄糖、肌酐和血尿素氮活性显著升高,而钠、氯、钾、钴、铁和硒活性显著降低与对照组相比。对 20 只骆驼进行了瘤胃切开术作为治疗 RRFBS 的手术干预。术后 6 个月,除 1 只仍有鼓气和轻微肿胀外,所有接受手术治疗的骆驼均已完全康复。总之,微量元素缺乏可能在单峰驼异物摄入综合征的发生中起重要作用。此外,临床、超声、血液学和生化学检查被认为是协助准确诊断、预后和治疗骆驼 RRFBS 的工具。
