Arthropod-borne hemoparasites represent a serious health problem in livestock, causing significant production losses. Currently, the evidence of spp., spp., spp., and hemotropic spp. in Algeria remains limited to a few scattered geographical regions. In this work, our objectives were to study the prevalence of these vector-borne pathogens and to search other agents not yet described in Algeria as well as the identification of statistical associations with various risk factors in cattle in the northeast of Algeria. Among the 205 cattle blood samples tested by PCR analysis, 42.4% positive results were obtained for at least one pathogen. The overall rates of spp., / spp., and spp. in the cattle sampled were respectively 30.7%, 18.5%, and 2.9%; co-infections with multiple species was also detected. spp. and spp. were detected at a higher rate in cattle under 3 years old, according to univariate analysis. spp. DNA was detected more frequently in our sample in cattle living in semi extensive farming. Our study provides additional data about spp., spp. and reveals for the first time that and ' Mycoplasma hemobos are present in cattle in Northeast Algeria.
节肢动物传播的血液寄生虫是家畜面临的一个严重健康问题，会造成重大的生产损失。目前，阿尔及利亚的[具体物种名称1]属、[具体物种名称2]属、[具体物种名称3]属和嗜血性[具体物种名称4]属的证据仍仅限于少数分散的地理区域。在这项工作中，我们的目标是研究这些媒介传播病原体的流行情况，寻找阿尔及利亚尚未描述的其他病原体，并确定与阿尔及利亚东北部牛群中各种风险因素的统计关联。在通过PCR分析检测的205份牛血样中，至少一种病原体的阳性结果为42.4%。所采样牛群中[具体物种名称1]属、[具体物种名称2/具体物种名称3]属和[具体物种名称4]属的总体感染率分别为30.7%、18.5%和2.9%；还检测到多种物种的共同感染。根据单变量分析，[具体物种名称1]属和[具体物种名称2]属在3岁以下的牛中检出率较高。在我们的样本中，生活在半粗放养殖模式下的牛群中[具体物种名称3]属DNA的检出频率更高。我们的研究提供了关于[具体物种名称1]属、[具体物种名称2]属的更多数据，并首次揭示阿尔及利亚东北部的牛群中存在[具体物种名称5]和溶血支原体。
