Book Description
provides all the basics of immunology in a convenient, easy-to-read format...explains the interactions between the fundamental principles of immunology and its clinical applications, with more than 130 high-quality color plates to illustrate the concepts described in the text
non-selective medium
Blood agar and chocolate agar, and examples of complex and non-selective environment that Any variety of bacteria are capable of growth on the environment. Non-selective medium for isolation of bacteria of unknown samples are important. When a clinical sample is injected into a non-selective medium, several types of bacterial colonies are visible.
the selective environment:
Because of the diversity of microorganisms in the sample material (eg, gastrointestinal) are stationary, the selective environment in order to eliminate (or reduce) the sample used in unrelated bacteria. Based on an element of choice environment growth inhibitor for Unwanted bacteria against bacterial pathogens is based. Examples of these include:
Sodium Zayd - against gram-positive bacteria, Gram-negative bacteria can be selected.
Bile salts: in the Enteric gram-negative bacteria And elimination of gram-negative bacteria and mucosal tissues are usually gram-positive bacteria.
Colistin and nalidixic acid to inhibit growth of Gram-negative bacteria.

Classification of bacteria
Classification, nomenclature and identification of three separate properties in the classification of bacteria, which has enormous significance.
Appropriate criteria used to classify Bactria to grow on the medium is biological.
Unlike viruses and many parasites, pathogenic bacteria can be isolated using an agar medium containing solids.
Bacterial culture medium containing nutrients and metabolic needs of the environment.
Usually agar medium containing a carbon source and an amino acid solution or an amino acid produced by the enzyme (casein)
. It is not clear because the exact composition of their environments to complex environments

Product Description:
This volume, derived from Encyclopedia of Virology, provides an overview of the development of virology during the last ten years. Entries detail the nature, origin, phylogeny and evolution of viruses. It then moves into a summary of our understanding of the structure and assembly of virus particles and describes how this knowledge was obtained. Genetic material of viruses and the different mechanisms used by viruses to infect and replicate in their host cells are highlighted. The volume is rounded out with an overview of some major groups of viruses with particular attention being given to our current knowledge of their molecular biology.
برای تکثیر ویروسها به جای محیطهای شیمیایی ساده بایستی سلولهای زنده فراهم شود. تهیه گیاهان و جانوران زنده برای نگهداری ویروسها ، دشوار و پر هزینه بوده و به علاوه ویروسهای بیماریزایی که فقط در پریماتهای عالی و انسان رشد میکنند مشکلات بیشتری را نیز فراهم مینمایند و از طرف دیگر ، ویروسهای باکتریها (باکتریوفاژها) را میتوان با پرورش آنها بر روی کشت باکتریها به آسانی تهیه کرد.
و از این رو است که قسمت اعظم اطلاعات بدست آمده در مورد تکثیر ویروسها از مطالعه این دسته از ویروسها بدست آمده است. بسیاری از ویروسها قادرند در کشتهای سلولی یا در تخم مرغهای جنیندار در شرایط کاملا کنترل شدهای تکثیر یابند. آزمایشگاههای تشخیصی سعی دارند به منظور اثبات عامل بیماری ، ویروسها را از نمونههای کلینیکی بدست آورند. آزمایشگاههای تحقیقاتی برای بررسی و تحلیل دقیق تکثیر و چگونگی تظاهر ژنهای ویروس ، آنها را کشت میدهند

Introduction to Modern Virology, 6 edition
Nigel Dimmock, Andrew Easton, Keith Leppard
Wiley-Blackwell | 2007 | ISBN:1405136456 | 536 pages | PDF | 5,3 MB
Introduction to Modern Virology has been an established student text for over 25 years. Providing an integrated account of the subject across different host systems, with an emphasis on human and animal viruses, this book covers the field of virology from molecular biology to disease processes using a unique systems approach. Featuring an all new art program in full color, the new edition has been updated throughout, and reorganized into thematic sections on the fundamental nature of viruses, their growth in cells, their interactions with the host organism and their role as agents of human disease. There is a new chapter on Human Viral Disease and rapidly developing areas, such as the use of viruses as gene therapy vectors, have been included.
The 6th edition is even more accessible, now including key points and integrative questions in every chapter, as well as text boxes emphasizing take-home messages, evidence underpinning the main concepts, and further information for more advanced readers. Prevention and therapy, evolution and emerging viruses receive particular attention and specific chapters address the major infectious challenges posed by HIV, pandemic influenza and BSE. This highly accessible text provides ideal reading for all undergraduate and postgraduate students of biology and medicine wishing to study virology.
The Human Genome, Third Edition: A User's Guide
Julia E. Richards, R. Scott Hawley
Ac..mic Press | 2010 | ISBN: 0123334454 | 600 pages | PDF | 30,7 MB
As genetic issues play a growing role in health practice and public policy, new knowledge in this field will continue to have significant implications for individuals and society.
Written to communicate sound and modern science in an accessible way for professionals and students with various levels of scientific background, this thoroughly revised edition of The Human Genome contributes to creating a genetically literate research and clinical population. With case studies and introductory vignettes which illustrate a wide range of perspectives on complex topics in genetics and updated material on the latest research on disease-specific topics, this book serves as a valuable resource for students and working professionals alike.
* Full-color illustrations enhance and reinforce key concepts and themes
* Chapters include interest boxes that focus on human health and disease, chapter-opening case studies, and concept statements to engage non-specialist readers
* Companion website includes self tests, electronic artwork, and a guide to additional web resources to meet the developing needs of health care professionals and researchers
