Recent outbreaks of swine influenza and avian influenza, along with the remaining and in some cases expanding threats from HIV, dengue virus, and the viruses causing hepatitis, have reinforced the need for rapid, accurate and cost-effective diagnosis of viral disease. Diagnostic Virology Protocols, Second Edition brings the field fully up-to-date with a focus on protocols involving nucleic acid detection, most often through some form of the polymerase chain reaction (PCR). The expert contributors also delve into the key technology of robotics as well as future prospects, such as further refined point-of-care testing and the increasing importance of mathematical modelling. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include brief introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Diagnostic Virology Protocols, Second Edition captures the dramatic changes in the virus diagnostic laboratory in order to better prepare scientists to combat the inevitable threats to public health from future and present infectious diseases.

The accurate and reliable diagnosis of transmissible diseases is the most powerful weapon available to ensure their control, and in some cases eradication. The detection of parasites in clinical cases, companion and farm animals, and in the environment is relatively easy since many of them are visible to the naked eye, and those that are not are readily detected by light microscopy. Fungal infections can similarly be determined. Bacteria are somewhat harder to detect. Although their presence can frequently be detected by light microscopy, differential diagnosis, beyond their gross morphology, is almost always impossible. However, most bacterial pathogens can be cultured in the laboratory and can be accurately identified by combinations of a series of simple tests such as morphology, staining, antibiotic sensitivity, biochemical analyses, nutrient dependence, and phage sensitivity. Viruses, however, have proved much more difficult; their size and absolute dependence of the host cell for propagation have rendered useless the methods traditionally used for other microorganisms. Until the development of tissue culture in the middle of this century, diagnosis was entirely dependent on the skill and experience of the clinician. But this was an unreliable process since many of the common virus infections exhibit similar clinical symptoms, such as coryza, exanthema, vomiting, diarrhea, neuralgia, and lethargy. Indeed many viral infections display clinical signs that are indistinguishable from bacterial or parasitic infections.

Johann Konrad Wilhelm Loehe (1808-1872) was one of the pivotal nineteenth century theologians in the struggle to restore a confessional identity to the Lutheran churches of Europe and North America. In an age when the doctrine of the ministry was contended on both sides of the Atlantic, Loehe found himself in a protracted struggle with theologians of the State Churches of Europe and various synods in North America over the nature and work of the pastoral office. As the translator for the 1849 Aphorisms notes in his preface: "Both sets of Aphorisms are not to be seen in isolation, but rather in intimate connection with the "churchly program" that Lohe developed with great energy (yet without detriment to his parish duties) in the years when he was most crippled with devastating grief over his wife's early death. The political crisis of 1848 awoke unfounded hopes in Lohe's breast that his "churchly program" might in fact be realised sooner rather than later. In the end of the day, perhaps only half of Lohe's aspirations turned into hard fact, namely, the establishment of the order of deaconesses and the erection of the "caritative" institutions bound up with the "procession of diakonia from the altar." To this day much of Lutheranism in the old world remains under the shackles of the State control that Lohe lamented in the shape of the "supreme episcopate of the princes." Moreover, his hopes of a renewed Lutheranism, centred in the sacrament of the altar, gladly and unforcedly practicing "unmixed eucharistic fellowship" (his term for our "closed communion"), and moving toward a greater fullness of liturgy, polity, and life than was achieved in the 16th century, have been sadly disappointed. Both sets of Aphorisms emerge from this context of conflict and expectation. With one foot in both Lutheran Orthodoxy and Lutheran Pietism (he would not see these successive ecclesial phenomena as alternatives), Lohe reached back behind these powerful factors in his formation to the New Testament text, his prime motivation being loyalty to revealed truth. From the communion of saints he surely bids us test his assertions against the yardstick of the inspired text."
