is one of the main causes of anemia in cattle, a lot of elucidations have been suggested to explain its pathogenesis. This study was designed to investigate clinical, hemato-biochemical and oxidant/antioxidant status and its relation with the resultant anemia in -infected calves. Seventeen (17) native breed calves were involved in this study, clinical signs and microscopic findings were recorded, also blood samples were taken to investigate hematologic changes, serum biochemical variations and oxidative stress biomarkers. The most commonly observed clinical signs were fever, emaciation, depression, icterus and hemoglobinuria. Significant reduction in PCV, HB, RBCs, MCHC, Total protein, and albumin along with significant increase in MCV, WBCs, monocytes and BUN were the most consistent hemato-biochemical changes. Oxidant/antioxidant and trace mineral assessment showed significant reduction in Superoxide dismutase "SOD", Glutathione peroxidase "GPx", Zn, Cu along with significant increase in malondialdehyde (MDA) activities. In the current investigation, oxidant/antioxidant imbalance along with the synchronized alterations in antioxidant trace minerals was detected in -infected calves. These findings support notion that infection associated with oxidative stress and this process may be linked to the resultant anemia.
是牛贫血的主要原因之一,人们提出了许多阐释来解释其发病机制。本研究旨在调查感染小牛的临床、血液生化和氧化/抗氧化状态及其与由此导致的贫血的关系。本研究纳入了17头本地品种小牛,记录了临床症状和显微镜检查结果,还采集了血样以调查血液学变化、血清生化变化和氧化应激生物标志物。最常观察到的临床症状是发热、消瘦、抑郁、黄疸和血红蛋白尿。红细胞压积、血红蛋白、红细胞、平均红细胞血红蛋白浓度、总蛋白和白蛋白显著降低,同时平均红细胞体积、白细胞、单核细胞和尿素氮显著增加,这些是最一致的血液生化变化。氧化/抗氧化和微量矿物质评估显示,超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GPx)、锌、铜显著降低,同时丙二醛(MDA)活性显著增加。在本次调查中,在感染小牛中检测到氧化/抗氧化失衡以及抗氧化微量矿物质的同步变化。这些发现支持了这样一种观点,即感染与氧化应激相关,并且这个过程可能与由此导致的贫血有关。
