RESUMO
The provision of blood and blood products free from contamination with any infectious agents is globally the aim of all blood transfusion services and the staff working within them. Currently in many countries there is great concern about the safety of the blood supply. Many infective agents are potentially transmissible through the transfusion of blood and its derivatives. Although the relative importance of different areas of the same country, transfusion microbiology practice is a topic of a global importance. This publication covers theoretical and practical aspects of modern transfusion microbiology and considers a wide range of infective agents, including those that may be of special significance for few countries only. This publications is intended for blood transfusion specialists, technologists and technicians, who must strive to ensure the provision of blood and blood derivatives free from contamination with infective agents

Sets out a logical and practical plan for the systematic monitoring of bacterial resistance to antimicrobial agents in countries of the Eastern Mediterranean Region. Advice on the development of a regional surveillance network is also provided. The booklet opens with background information about the growing problem of antimicrobial resistance, the contributing factors, and the consequences in terms of patient care and costs, particularly in developing countries. Against this background, precise guidelines for the surveillance of antimicrobial resistance are presented in seven sections. The first two provide general rules for the selection of indicator organisms, followed by a list of 36 organisms suggested for inclusion in a monitoring scheme. Organisms that should not be monitored are also listed, together with brief explanations of reasons for their exclusion. Section three provides guidelines for the selection of the most appropriate antibiotics for testing, noting that, for most groups of organisms, six or seven antibiotics are sufficient for routine reporting. Recommended antibiotics are then listed for nine groups of organisms. The remaining sections present summary protocols for antimicrobial susceptibility testing by the disc diffusion method, and discuss both traditional and non-traditional approaches to the quality control of susceptibility tests
