Abstract

An acute bacterial infection called avian spirochetosis is spread by ticks to a variety of birds. Clinical symptoms can vary greatly and are frequently non-specific. To diagnose a condition, the infectious spirochete must be detected. Here, we structure an epidemic model for the transmission of avian spirochetosis to visualize the interaction between tick and bird populations. The recommended dynamics of avian spirochetosis is illustrated with the help of fractional framework. We inspected the steady-states of the system of the avian spirochetosis for the stability analysis. The next-generation technique is used to evaluate the model's reproduction parameter The infection-free and endemic steady-state of avian spirochetosis were shown to be locally asymptotically stable under the specified conditions. Through mathematical skills, the positivity of solutions is determined. Additionally, evidence supporting the existence and uniqueness of the avian spirochetosis framework solution has been shown. We conduct modified simulations of the suggested avian spirochetosis system with different input factors to study the complex phenomena of avian spirochetosis under the effect of numerous input parameters. Our outcomes illustrate the significance and plausibility of fractional parameter, and they also suggest that this input parameter may adequately account for these kinds of observations.

摘要

一种名为禽类螺旋体病的急性细菌性感染通过蜱传播给多种鸟类。临床症状差异很大,且通常无特异性。为了诊断病情,必须检测到传染性螺旋体。在这里,我们构建了一个禽类螺旋体病传播的流行模型,以直观地展示蜱和鸟类种群之间的相互作用。借助分数框架,我们说明了推荐的禽类螺旋体病动力学。我们检查了系统的稳定状态,以进行稳定性分析。利用下一代技术评估模型的繁殖参数。在规定条件下,证明了禽类螺旋体病的无感染和地方病稳定状态是局部渐近稳定的。通过数学技巧,确定了解的正定性。此外,还证明了支持禽类螺旋体病框架解的存在性和唯一性的证据。我们对建议的禽类螺旋体病系统进行了不同输入因素的修正模拟,以在多种输入参数的影响下研究禽类螺旋体病的复杂现象。我们的结果说明了分数参数的重要性和合理性,并且还表明该输入参数可以很好地解释这些观察结果。
