Sixty Bubaline milk samples with corresponding blood samples were obtained from flocks at random in Cairo and Giza Governorates. The aerobic bacteria & somatic cells were counted and evaluated the physicochemical parameters of milk. Both milk and serum of buffaloes' were evaluated for tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and interferon (IFN-ɤ) by quantitative real-time PCR protocol, and oxidative stress markers were measured spectrophotometrically. There was a significant difference (p < 0.05) between the mean values of whole milk physicochemical aspects except the moisture % & pH values were recorded for infested and non-infested animals. For F. gigantica infested animals, the milk TNF-α, IL-1β, interferon IFN-γ, malondialdehyde (MDA), and total antioxidant capacity (TAC) values were 17.5 ± 0.67, 18.5 ± 0.71, 19.25 ± 0.74, 7.75 ± 0.29, and 1.1 ± 0.04, respectively (lesser than serum values) with a significant difference (p < 0.05) between positive and negative samples for both examined serum and milk samples. There was also a significant (p < 0.05) negative relationship between MSCC & fat% and protein%, while a significant (p < 0.05) positive relationship between MSCC and the investigated milk cytokines in F. gigantica infested animals. This study is considered one of the fewest investigations of milk cytokines and oxidative stress markers in buffaloes fascioliasis diagnosis. Meanwhile, monitoring these genes modification that is active in the milk-producing gland is significant to typify the act technicality of the inherited immunity that helps the progress of schemes to retain the udder health.
从开罗和吉萨省的牛群中随机抽取了 60 份野牛奶样本和相应的血样。对需氧细菌和体细胞进行计数,并评估牛奶的理化参数。通过定量实时 PCR 方案评估水牛奶和血清中的肿瘤坏死因子-α(TNF-α)、白细胞介素-1β(IL-1β)和干扰素(IFN-ɤ),并通过分光光度法测量氧化应激标志物。受肝片吸虫感染和未感染动物的全脂牛奶理化方面的平均值存在显著差异(p<0.05)。对于感染肝片吸虫的动物,牛奶 TNF-α、IL-1β、干扰素 IFN-γ、丙二醛(MDA)和总抗氧化能力(TAC)值分别为 17.5±0.67、18.5±0.71、19.25±0.74、7.75±0.29 和 1.1±0.04(低于血清值),阳性和阴性样本之间存在显著差异(p<0.05)。在受肝片吸虫感染的动物中,MSCC 与脂肪%和蛋白质%呈显著负相关(p<0.05),而 MSCC 与所研究的牛奶细胞因子呈显著正相关(p<0.05)。本研究被认为是少数对水牛肝片吸虫病诊断中牛奶细胞因子和氧化应激标志物进行研究的研究之一。同时,监测这些在产奶腺中活跃的基因修饰对于典型的遗传免疫技术特性具有重要意义,这有助于保留乳房健康计划的进展。
