Helminth infections in cage-free laying chickens in Australia- prevalence, coprological diagnosis, and worm egg storage and infectivity in chickens - Dataset None None

This abstract briefly summarizes data collected from a series of experiments forming a total of 5 chapters in Anwar Shifaw’s PhD thesis (2023). The data were collected from field samples and laboratory experiments. One category of data (Chapter 3) was obtained by extracting useful information from published studies in order to compile prevalence data for both qualitative and quantitative analysis. The extracted information included study details (such as authors, years, study regions, breed or strain, age, sex, production system, study design, sampling type, and sample size), diagnostic method, and helminth species and prevalence. Data for chapter 4 were generated from field samples. Measurements include worm count and excreta egg count for assessing worm prevalence and infection intensity. Data for Chapter 5 were derived from egg spiked and naturally infected chicken excreta samples, measuring excreta egg count and the time spent in processing samples by the two egg counting diagnostic methods to evaluate their diagnostic performance. Data for Chapter 6 were obtained from worm eggs recovered from chicken excreta and stored for an extended period of time, with several factors assessing their effects on the developmental stage and egg viability which were expressed as percentage (%). The final experiment (Chapter 7) was a worm propagation study and measurements included chicken body weight and excreta egg count (EEC, expressed as eggs/gram of excreta/EPG) recorded over time until 12 weeks post-infection, and worm counts recorded at 12 weeks post-infection. All data collected from each experiment were entered into excel file separately with detailed information and keys of different abbreviations used on separate sheets. Data from some parameters such as EEC, and worm count cube transformed before analysis to attain normality of data distribution.

本摘要简要汇总了Anwar Shifaw于2023年完成的博士论文中5个章节所涉及的系列实验采集的数据。该数据集来源于野外样本采集与实验室实验两类工作。其中第3章对应的数据类别，通过从已发表研究中提取有效信息以汇编感染流行率数据，用于定性与定量分析；提取的信息涵盖研究详情（包括作者、发表年份、研究区域、品种/品系、年龄、性别、生产系统、研究设计、采样类型与样本量）、诊断方法、蠕虫物种及其感染流行率。第4章的数据来源于野外采集的样本，测量指标包括蠕虫计数与粪便虫卵计数，用于评估蠕虫感染流行率与感染强度。第5章的数据来自人工添加虫卵与自然感染的鸡粪便样本，通过两种虫卵计数诊断方法处理样本，测量粪便虫卵计数与样本处理耗时，以评估两种方法的诊断性能。第6章的数据取自从鸡粪便中回收并长期保存的蠕虫虫卵，通过多维度因素评估其对虫卵发育阶段与存活能力的影响，结果以百分比（%）形式呈现。最后一项实验（第7章）为蠕虫增殖研究，测量指标包括鸡只体重与粪便虫卵计数（EEC，以每克粪便虫卵数（EPG）表示），记录感染后12周内的相关指标，并于感染后12周时统计蠕虫计数。每项实验采集的所有数据均单独录入Excel文件，不同缩写的详细说明与键值表均单独存放于工作表中。部分参数（如EEC与蠕虫计数）的数据在分析前会进行立方变换，以满足数据分布的正态性要求。
