    Ecoepidemiology and Potential Transmission of Vibrio cholerae among Different Environmental Niches: An Upcoming Threat in Egypt
    (MDPI AG, 02/10/2021) Ismail, Eman M; Kadry, Mona; Elshafiee, Esraa A; Ragab, Eman; Morsy, Eman A; Rizk, Omar; Zaki, Manal M
    Cholera is a negative public health event caused by Vibrio cholerae. Although V. cholerae is abundant in natural environments, its pattern and transmission between different niches remain puzzling and interrelated. Our study aimed to investigate the occurrence of nonpathogenic V. cholerae in the natural environment during endemicity periods. It also aimed to highlight the role of molecular ecoepidemiology in mapping the routes of spread, transmission, and prevention of possible future cholera outbreaks. V. cholerae was detected in different aquatic environments, waterfowl, and poultry farms located along the length of the Nile River in Giza, Cairo, and Delta provinces, Egypt. After polymerase chain reaction amplification of the specific target outer membrane gene (Omp W) of suspected isolates, we performed sequence analysis, eventually using phylogenetic tree analysis to illustrate the possible epidemiological relationships between different sequences. Data revealed a significant variation in the physicochemical conditions of the examined Nile districts related to temporal, spatial, and anthropogenic activities. Moreover, data showed an evident association between V. cholerae and the clinically diseased Synodontis schall fish. We found that the environmental distress triggered by the salinity shift and elevated temperature in the Middle Delta of the Nile River affects the pathogenesis of V. cholerae, in addition to the characteristics of fish host inhabiting the Rosetta Branch at Kafr El-Zayat, El-Gharbia province, Egypt. In addition, we noted a significant relationship between V. cholerae and poultry sources that feed on the Nile dikes close to the examined districts. Sequence analysis revealed clustering of the waterfowl and broiler chicken isolates with human and aquatic isolated sequences retrieved from the GenBank databases. From the obtained data, we hypothesized that waterfowl act as a potential vector for the intermediate transmission of cholera. Therefore, continuous monitoring of Nile water quality and mitigation of Nile River pollution, in addition to following good managemental practices (GMPs), general hygienic guidelines, and biosecurity in the field of animal production and industry, might be the way to break this cyclic transmission between human, aquatic, and animal sectors. © 2021 by the author.

    Fuzzy-Based Framework for Enterprise Resource Planning System Selection
    (IEEE, 2012) Hegazy, Abd El-Fatah A.; El-Battah, Mahmoud; Kadry, Mona
    The popularity of enterprise resource planning is globally increasing for being the magical word to integrate and automate all areas of business operations. However, many organizations are still having hard times to select the proper ERP package. Selection of an ERP system is a crucial decision since implementing ERP is complex, very expensive and time-consuming. Furthermore, the problem of ERP system selection was classified as a complex multiple-criteria decision-making (MCDM) problem due to the multiplicity of conflicting criteria that need to be evaluated in making the selection decision. The study started by determining the ultimate evaluation criteria and business goals of ERP, and then defined 185 sub-criteria and attributes for evaluating ERP packages. The study proposed a comprehensive framework for the process of ERP system selection that uses fuzzy logic as a method to deal with the ambiguous and conflicting opinions of the decision makers. In addition, intelligent rule chaining was constructed to reduce the number of rules used for evaluation. At last, a real-world case study for an Egyptian garments manufacturer was conducted to demonstrate the feasibility of the proposed framework. The study found out that applying ERP systems in a manufacturing environment needed special industrial requirements that may lead to ERP failure in case of selecting the improper ERP package using the traditional selection techniques.
