Fascioliasis is one of the most prevalent and economically significant parasitic illnesses of domestic animals, particularly cattle, sheep, goats, and man. It is particularly widespread in countries with heavy cattle production especially places with low interest in vector-related diseases. Therefore, the study was designed to investigate the prevalence of this parasitic disease among the cattle slaughtered in the selected abattoirs in Oyo, Oyo State, Nigeria. Two hundred and fifty (250) faecal samples were collected from the rectum of the slaughtered cattle. The samples were analyzed using the Formol-ether Concentration technique. Also, post mortem examination of the liver and other organs of the slaughtered cattle (250) at the abbattior were also examined for Fasciola infestation. The data were were analyzed with Chi-square at 5% level of significance using SPSS. It was observed that 77 (30.8%) were positive to fascioliasis out of the 250 slaughtered cattle examined. The prevalence of the infection based on the sex of the cattle was found to be statistically significant (p = 0.001).The percentage of fascioliasis depending on the breed of the cattle was observed to be lowest (25%) in Sokoto Gudali and highest (33.33%) in White Fulani. The analysis implied that there was a strong association between infection and cattle breeds. Prevalence of fascioliasis based on the estimated age of animals was not statistically significant however; animals aged 3 years and 6 months had the highest percentage (54.1%) while those within 2 years and 6 months had no cases of fascioliasis. Fascioliasis is an endemic illness in the study area among cattle slaughtered for consumption. This suggests the possibility of human infestation through consumption especially when it is under-processed. The need for health policy to ensure slaughtering of healthy cattle become important to ensure safe public health especially through consumption of meat. Also, public health intervention through mass vaccination of cattle, education of cattle farmers and introduction of veterinary inspectors at the point of slaughter is important in controlling Fascioliasis.
蝇蛆病是家畜(尤其是牛、绵羊、山羊和人)最常见、最具经济意义的寄生虫病之一。这种疾病在畜牧业发达的国家尤为普遍,特别是在对病媒相关疾病不感兴趣的地方。因此,本研究旨在调查这种寄生虫病在尼日利亚奥约州奥约市选定屠宰场屠宰的牛群中的流行情况。研究人员从屠宰牛的直肠中收集了 250 份粪便样本。样本采用福尔马林-乙醚浓缩技术进行分析。此外,还对屠宰场屠宰的 250 头牛的肝脏和其他器官进行了死后检查,以确定是否存在法氏囊虫感染。使用 SPSS 对数据进行了 5%显著性水平的卡方分析。结果显示,在接受检查的 250 头屠宰牛中,有 77 头(30.8%)对法氏囊病呈阳性反应。根据牛的品种,发现索科托古达利牛的法氏囊炎感染率最低(25%),而白富拉尼牛的感染率最高(33.33%)。分析表明,感染与牛的品种有很大关系。然而,根据动物的估计年龄计算的法氏囊病患病率在统计上并不显著;3 岁 6 个月的动物患病率最高(54.1%),而 2 岁 6 个月以内的动物则没有法氏囊病病例。法氏囊病是研究地区屠宰食用牛的一种地方病。这表明人类有可能通过食用而感染这种疾病,尤其是在加工不足的情况下。为确保公共卫生安全,尤其是通过肉类消费确保公共卫生安全,制定卫生政策以确保屠宰健康的牛变得非常重要。此外,通过对牛进行大规模疫苗接种、对养牛人进行教育以及在屠宰点引入兽医检查员等方式进行公共卫生干预,对于控制法氏囊病也很重要。

This review article provides an in-depth analysis of the biological invasions of begomoviruses, focusing on a prominent case study involving the Tomato Yellow Leaf Curl Virus (TYLCV) and its vector, the whitefly Bemisia tabaci, in the unique agricultural landscape of Oman. Begomoviruses, known for their global impact on crop yields, have become a significant concern in Oman, posing a serious threat to the cultivation of various crops, particularly tomatoes. The review begins by exploring the molecular characteristics and ecological dynamics of TYLCV and Bemisia tabaci, shedding light on the intricate interactions between the virus, the vector, and the host plants. Through a comprehensive analysis of historical data and recent research findings, the article examines the patterns and pathways of invasion, elucidating the factors contributing to the successful establishment and spread of TYLCV in Oman. The impacts of TYLCV invasion on agricultural productivity and crop quality are critically evaluated, providing insights into the specific challenges faced by Omani farmers. Special attention is given to the socio-economic repercussions of TYLCV-induced crop losses, emphasizing the need for adaptive management strategies to mitigate the negative consequences on food security and rural livelihoods. Furthermore, the review assesses the current state of knowledge regarding the management and control of TYLCV and Bemisia tabaci in Oman. It discusses the successes and limitations of existing strategies, ranging from conventional practices to innovative biotechnological approaches, providing a foundation for future research directions and the development of sustainable management practices in the context of biological invasions of begomoviruses in Oman. Overall, this review contributes to a nuanced understanding of the complex interplay between invasive begomoviruses, their vectors, and local agricultural systems, offering valuable insights for researchers, policymakers, and practitioners engaged in crop protection and biosecurity in Oman and beyond.

In Villa Clara province, Cuba, microorganisms and climatic conditions coexist for the development of the infectious entity chromoblastomycosis. Besides, there is a high percentage of agricultural and handicraft workers exposed to acquiring this infection. The objective of the research consisted in describing the etiological diagnosis and correlating chromoblastomycosis with average climatic variables of the meteorological stations located in Villa Clara. Between 2018-2022, a descriptive, cross-sectional study was conducted in a population of 25 patients diagnosed with chromoblastomycosis by anatomopathological and microbiological studies. Absolute frequencies were used as a summary measure, and for correlation with climatic data from the five meteorological stations, inferential statistics. Of the total number of patients, 92% were diagnosed by anatomopathological studies and only 2/8% had mycological studies, in which the species Fonsecaea pedrosoi was isolated. There was a significant correlation between mean temperature (p=0.045) and mean predicted wind (p=0.028) and the number of cases. This was not the case with relative air humidity (p>0.05). It is concluded that in Villa Clara province, only the etiological agent F. pedrosoi was the cause of the disease during the period studied, with a significant relationship between the disease and the average climatic variables mean temperature and mean predicted wind.
在维拉克拉拉省,古巴,微生物和气候条件共存的发展感染性实体嗜色菌病。此外,暴露于感染这种感染的农业和手工业工人的比例很高。研究的目的在于描述成色菌病的病原学诊断,并将其与位于维拉克拉拉的气象站的平均气候变量进行关联。在2018-2022年期间,对25名通过解剖病理学和微生物学研究诊断为成色菌病的患者进行了一项描述性横断面研究。绝对频率被用作汇总度量,并用于与五个气象站的气候数据的相关性,推断统计。在所有患者中,92%的患者通过解剖病理学检查诊断,只有2/8%的患者进行了真菌学研究,其中分离到了Fonsecaea pedrosoi。平均气温(p=0.045)、平均预测风(p=0.028)与病例数呈显著相关。相对空气湿度则不是这样(p>0.05)。结果表明,在维拉克拉拉省,在研究期间,只有病原F. pedrosoi是该疾病的病因,该疾病与平均气候变量、平均温度和平均预测风有显著关系。

Machine learning is a powerful tool for creating computational models in scientific analysis in areas where there is need to extract hidden data such as educational data. In order to make planning easier and identify at-risk students who may be in danger of failing or dropping out of school due to their academic performance, Educational Data Mining (EDM) uses computational tools. In this paper, a framework using machine learning approach was proposed to develop an enhanced algorithm for non-cognitive variables influencing students’ performance using feature extraction. In the framework, the Decision Tree (DT) and Linear Support  Vector Machine (SVM) are proposed as base classifiers, and Random Forest (RF) and Gradient Boosting (GB) as ensemble classifiers. The DT classifier allows the classification process to be modelled as a series of hierarchical decisions on the features, forming a tree-like structure. Using this technique, planning and predicting students who might be at-risk of dropping out would have been made easier.
机器学习是在需要提取隐藏数据(如教育数据)的领域中创建科学分析计算模型的强大工具。教育数据挖掘(EDM)使用计算工具,使计划更容易,并识别有可能因学业成绩不及格或辍学的高危学生。本文提出了一个使用机器学习方法的框架,利用特征提取来开发一种增强的算法,用于处理影响学生表现的非认知变量。在该框架中,提出了决策树(DT)和线性支持向量机(SVM)作为基分类器,随机森林(RF)和梯度增强(GB)作为集成分类器。DT分类器允许将分类过程建模为一系列关于特征的分层决策,形成树形结构。使用这种技术,计划和预测可能有退学风险的学生将变得更加容易。
