Pcr Protocols For Diagnosis Of Human And Animal Virus Diseases

The polymerase chain reaction (PCR) is the most sensitive method for revealing the presence of otherwise undetectable quantities of the genome of RNA or DNA of human viruses. The Polymerase Chain Reaction (PCR) for Human Viral Diagnosis addresses the urgent need to use this revolutionary technology in reference and routine diagnostic laboratories. It informs the molecular biologist of the most appropriate clinical uses for PCR and educates the clinician and medical virologist about the subtleties and benefits of gene amplification. The reader is given an understanding and appreciation of the principles of PCR and how, why, and where it should be applied. The book explains the principles behind PCR and its role in the diagnostic and public health laboratory. The application of PCR to the detection and investigation of viral latency and persistence is presented by the originators of in situ amplification. There are individual contributions from experts in their respective fields on the detection, characterization, and analysis by PCR of gastroenteritis viruses, hepatitis viruses, herpesviruses, rhinoviruses, enteroviruses, flaviviruses, polyomaviruses, human immunodeficiency virus (HIV), human T-lymphotropic virus types I and II (HTLV-I and II); and measles, mumps, rubella, influenza, rabies, and B19 viruses.

This detailed book explores new molecular biological techniques for the detection of both antigens and antibodies of porcine diseases. Assays examined within this collection include improved methods of nucleic acid extraction, polymerase chain reaction (PCR), droplet digital PCR (ddPCR), polymerase spiral reaction (PSR), cross-priming amplification (CPA), enzyme-linked immunosorbent assay (ELISA), as well as peptide nucleic acid (PNA) based tools, aptamer-based tools, and lateral flow assays and different immune assay-based diagnostics for porcine diseases. As part of the Springer Protocols Handbooks series, the present book contains the type of in-depth knowledge on important diagnostics tools that provide a vital source of information for scientists, researchers, and students from different fields. Authoritative and practical, Protocols for the Diagnosis of Pig Viral Diseases aims to guide researchers toward developing new technologies for the diagnosis of pig pathogens.

The basis for the effective treatment and cure of a patient is the rapid diagnosis of the disease and its causative agent, which is based on the analysis of the clinical symptoms coupled with laboratory tests. Although rapid advance ments have been made in the laboratory diagnosis of virus diseases, the neces sary isolation of the causative virus from the clinical specimens is a relatively long procedure. Viruses which integrate into the cellular DNA (such as human immunodeficiency virus, HIV -1, or hepatitis B virus) are difficult to identify by molecular techniques, while viruses which exist in the clinical material in low concentrations are even more formidable to identify. Recently, the application of the polymerase chain reaction (peR) technique developed by K. D. Mullis and detailed in the study by Saiki et al. (1985) led to a revolution in virus diagnosis. The peR technique was rapidly applied to the diagnosis of viruses in clinical material. Volume 1 of Frontiers of Virology provides new information on the advan tages of the use of the peR for the diagnosis of many human disease-causing viruses, as well as on some problems with its use.

Early detection is essential to the control of emerging, reemerging, and novel infectious diseases, whether naturally occurring or intentionally introduced. Containing the spread of such diseases in a profoundly interconnected world requires active vigilance for signs of an outbreak, rapid recognition of its presence, and diagnosis of its microbial cause, in addition to strategies and resources for an appropriate and efficient response. Although these actions are often viewed in terms of human public health, they also challenge the plant and animal health communities. Surveillance, defined as "the continual scrutiny of all aspects of occurrence and spread of a disease that are pertinent to effective control", involves the "systematic collection, analysis, interpretation, and dissemination of health data." Disease detection and diagnosis is the act of discovering a novel, emerging, or reemerging disease or disease event and identifying its cause. Diagnosis is "the cornerstone of effective disease control and prevention efforts, including surveillance." Disease surveillance and detection relies heavily on the astute individual: the clinician, veterinarian, plant pathologist, farmer, livestock manager, or agricultural extension agent who notices something unusual, atypical, or suspicious and brings this discovery in a timely way to the attention of an appropriate representative of human public health, veterinary medicine, or agriculture. Most developed countries have the ability to detect and diagnose human, animal, and plant diseases. Global Infectious Disease Surveillance and Detection: Assessing the Challenges-Finding Solutions, Workshop Summary is part of a 10 book series and summarizes the recommendations and presentations of the workshop.

Today the diagnosis of human and animal pathogenic viruses would be unthinkable without the polymerase chain reaction (PCR). The short-styled protocols in this volume elucidate this important technique and its application in the laboratory, including a discussion of recent advances in PCR technology. The enclosed diskette enables the user to work with interesting sequences on his own computer.

The book gives a comprehensive overview on the knowledge of virus infection relevant for humans and animals. For each virus family the molecular details of the virus particle and the viral replication cycle are described. In the case of virus types with relevance for human and/or animal health the data on molecular biology, genetics and virus-cell interaction are combined with those concerning, pathogenesis, epidemiology, clinics, prevention and therapy.

PREFACE The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture is involved in agricultural research and development and assists Member States of FAO and IAEA in improving strategies to ensure food security through the use of nuclear techniques and related biotechnologies, where such techniques have a valuable and often unique role. In particular, molecular diagnostic methods have rapidly evolved in the past twenty years, since the advent of the Polymerase Chain Reaction (PCR). They are used in a wide range of agricultural areas such as, improving soil and water management; producing better crop varieties; diagnosing plant and animal diseases; controlling insect pests and improving food quality and safety. The uses of nucleic acid-directed methods have increased significantly in the past five years and have made important contributions to disease control country programmes for improving national and international trade. These developments include the more routine use of PCR as a diagnostic tool in veterinary diagnostic laboratories. However, there are many problems associated with the transfer and particularly, the application of this technology. These include lack of consideration of: the establishment of quality-assured procedures, the required set-up of the laboratory and the proper training of staff. This can lead to a situation where results are not assured. This book gives a comprehensive account of the practical aspects of PCR and strong consideration is given to ensure its optimal use in a laboratory environment. This includes the setting-up of a PCR laboratory; Good Laboratory Practice and standardised of PCR protocols.
