Camel mastitis is indeed a serious problem that can have significant impacts on animal health and production as well as pose a potential public health hazard. This work aimed to identify the bacterial species responsible for camel mastitis and evaluate the associated immunological and clinicopathological alterations in infected camels.
Raw milk and blood samples were collected from 40 apparently healthy she-camels, and 40 she-camels suffered from clinical mastitis (CMG). Milk samples were subjected to bacteriological examination. Serum immunological, biochemical, and hematological parameters were estimated and statistically analyzed.
Similar bacterial species were obtained from the two groups with different isolation rates. and were the dominant species in the apparently healthy group, whileand were the dominant species in CMG. A significant ( < 0.05) elevation of the pro-inflammatory cytokines, acute phase proteins (APPs), free radicals, total protein, Glob, kidney and liver function tests, and triglyceride concentrations were detected in CMG, and a significant ( < 0.05) decrease in the anti-inflammatory cytokine, antioxidants, Alb, glucose, and T/LDL/HDL-cholesterol concentrations was observed in CMG. Microcytic hypochromic anemia with hypoferremia, hypotransferrinemia, hyperferritinemia, and neutrophilic leukocytosis was depicted in CMG. The estimated pro-inflammatory cytokines, APPs, and total antioxidant capacity (TAC) yielded high sensitivity and specificity, but the highest likelihood ratio was for TAC, fibrinogen (Fb), and ferritin, and the highest percentages of increase were for IL-1α and IL-1β.
The study emphasizes the importance of hygienic preventive measures to control camel mastitis and the importance of supportive treatment to reverse the hemato-biochemicaland iron profile changes that result from the immune response in mastitic she-camels. TAC, Fb, ferritin, IL-1α, and IL-1β are good biomarkers for camel mastitis.
骆驼乳腺炎确实是一个严重问题,会对动物健康和生产产生重大影响,并构成潜在的公共卫生危害。本研究旨在鉴定引起骆驼乳腺炎的细菌种类,并评估感染骆驼相关的免疫和临床病理变化。
从40头看似健康的雌性骆驼和40头患有临床乳腺炎(CMG)的雌性骆驼中采集生鲜乳和血液样本。对乳样进行细菌学检查。对血清免疫、生化和血液学参数进行评估并进行统计分析。
两组分离出相似的细菌种类,但分离率不同。[具体细菌名称1]是看似健康组的优势菌种,而[具体细菌名称2]和[具体细菌名称3]是CMG组的优势菌种。在CMG组中检测到促炎细胞因子、急性期蛋白(APPs)、自由基、总蛋白、球蛋白、肾功能和肝功能检测指标以及甘油三酯浓度显著(P<0.05)升高,而抗炎细胞因子、抗氧化剂、白蛋白、葡萄糖以及总胆固醇/低密度脂蛋白/高密度脂蛋白浓度显著(P<0.05)降低。CMG组表现为小细胞低色素性贫血伴低铁血症、低转铁蛋白血症、高铁蛋白血症和中性粒细胞增多。所评估的促炎细胞因子、APPs和总抗氧化能力(TAC)具有较高的敏感性和特异性,但TAC、纤维蛋白原(Fb)和铁蛋白的似然比最高,而白细胞介素-1α(IL-1α)和白细胞介素-1β(IL-1β)的升高百分比最高。
该研究强调了卫生预防措施对控制骆驼乳腺炎的重要性,以及支持性治疗对逆转患乳腺炎雌性骆驼因免疫反应导致的血液生化和铁代谢变化的重要性。TAC、Fb、铁蛋白、IL-1α和IL-1β是骆驼乳腺炎的良好生物标志物。
