Abstract

Background: Diarrhea is a major cause of morbidity and mortality in children under 5 years old in developing countries. Objective: This study designed to investigate the occurrence of extended spectrum beta-lactamase producing Escherichia coli (E. coli ) as etiological infectious agents of diarrhea in children, assessment of their susceptibility/resistance to antibiotics, and to evaluate the antibacterial activity of the macroalgae Cladophora crispata extract towards these bacteria . Materials and Methods: 150 diarrheic stool samples were collected from children less than 5 years and cultured. The isolated bacteria were subjected to various identification and biochemical tests. Then all the isolated bacteria (E. coli ) were subjected to ESBL-producing screening by double-disc synergy test, the antibacterial activity of algal extract and antibiotic susceptibility test against tested bacteria were determined by using agar well diffusion and disc diffusion methods respectively . Results: Out of total 150 samples, only 18 isolates revealed the presence of extended spectrum β-lactamase producing E. coli, which showed highly susceptibility to gentamicin and amikacin, Cladophora crispata extract revealed a strong antibacterial activity against ESBL-producing E. coli. Conclusion: Cladophora crispata extract showed a strong antibacterial activity against ESBL-producing E. coli which can be exploited as source of antibacterial drugs to control and treatment diarrheal infection caused by these bacteria.

Abstract

The ability of various soaking media in enhancing the temperature of waste materials, once they are exposed to microwaves has been investigated. Such information helps development of microwave techniques to destroy viruses, spores and other microorganisms by temperature enhancement if they may not be affected by microwave radiation itself. Oily media were observed to have higher elevation in temperature; however, they have the inherent drawback of sticking into the inner surface of the container. Such drawbacks can be minimized by using enclosed non-stick container for the microwave application. Among aqueous fluids, commonly found detergent solution showed the best performance in raising the temperature. Such material has many other advantages such as, low cost, non-toxic nature, environment friendliness, ready availability etc.

Abstract

With emergence of technology and growing demand of the society, e-Governance became a key issue and developed nations started adopting it to better serve their organizations through efficient and effective services, with accountability and transparency. e-governance can be defined as a set of activities involving the effective contribution of information and communication technology (ICT) for strengthening administration and management e-governance is the use of Information and Communication Technologies (ICT) for the planning, implementation, and monitoring of higher education programs, projects, and activities. The higher education sector has remarkable growth in the administration of institutions intricate. Many paperes reveal that the integration of ICT helps to reduce the intricacy and enhance the overall administration of higher education. e-Governance is expected to help deliver cost-effective and easy-to-access user services, and improve processing of transactions. . The Iraqi higher education system has declined somewhat over the past three decades due to remarkable increase in the number of colleges and universities and their privatization. It has become very important for the government to keep track of their functioning. Educational institutions may have various requirements that include computerization and management of processes such as registration, admission, student information, classes, time table, transport, attendance, library, salary and expenses, examinations, performance, grades, hostels, security and reports. In this paper, an attempt have been made to discuss the concept of e-governance and use of latest application in higher education sector. This study also propose a roadmap to the implementation of an e-governance framework for monitoring, regulating and better administration in Iraqi higher education system.

Abstract

Background: Periodontal diseases are highly prevalent in Iraq. They may become serious conditions if they faced by unsuitable treatment and resulting in particularly cardiovascular systemic disorders. Further, antibiotic resistance in general has been witnessed prevalence, which may lead to failure of periodontal disease treatment. The aim of this study is evaluation of susceptibility and resistance to different antibiotics by dental plaque bacterial isolates. Material and methods: Thirty seven infected patients were included in this study. From their dental plaque, samples were taken aseptically then bacteria has been isolated as well as antibiotic susceptibility tests agar diffusion methods had been applied. Results: Among three types of bacteria, Streptococcus mutans occupied the largest percentage (62%) in dental plaque isolates. Imipenem registered profound susceptibility (78.3%) via Streptococcus mutans followed by each of erythromycin, ciprofloxacin, and ceftriaxone (60.9%). This pathogen isolates showed resistance to amikacin, chloramphenicol, tetracycline and amoxicillin. Pseudomonas aeruginosa appeared the highest susceptibility to chloramphenicol and ceftriaxone by (90%) while Staphylococcus aureus had been existed complete susceptibility to imipenem (100%) followed directly by tetracycline and chloramphenicol by about (75%) of each. The lowest susceptibility was resulted toward amoxicillin, amikacin, and ciprofloxacin with (25%). Generally speaking, amoxicillin exposed to highest resistance (70.3%) in comparison to others, whereas both of imipenem and ceftriaxone witnessed highest susceptibility (67.6%) by the same pathogens. Conclusions: Amoxicillin occupied the first position in bacterial resistance, this may support the assumption that improper administration of amoxicillin will lead to therapy failure.
