Revue Scientifique et Technique: Diseases of poultry: World trade and public health implications
Bibliographic record
Abstract
Production of this excellent paperback volume was coordinated by 2 prominent experts in poultry health, and the authors are authorities on the various diseases. The book contains 17 chapters; each gives up-to-date information on a disease or group of diseases considered to be particularly important in international trade. In addition, information is given on the public health significance of each disease. The final chapter on ostrich diseases contains valuable information on pathogens that are of concern in that species or may spread between ostriches and chickens. The book will be particularly appreciated by veterinarians and other professionals who must make decisions on the movement of eggs and poultry within their countries and across international borders, but it will also benefit anyone seeking information on poultry diseases of major importance. All chapters are written in English, with summaries in French and Spanish. The chapter on infectious bursal disease is given in both French and English. Ample references are given for each chapter. Food-borne infections are dealt with in chapters on paratyphoid Salmonella and Campylobacter spp. The devastating effects that inappropriate disease control legislation can have on the poultry industry is discussed in the chapter on Salmonella. This chapter also includes useful information on public health implications arising from the use of antibiotics by the poultry and food animal industries. The chapter on campylobacteriosis indicates that the prevalence of infection with Campylobacter jejuni in broiler flocks in various poultry producing countries ranges from 17% to 90%. Campylobacteriosis has been regarded as an occupational infection of poultry plant workers, and it is noted that outbreaks resulting in death have occurred in abattoir workers. Another concern is that autoimmune conditions may follow infections. Again, useful information is given on antibiotic resistance to the pathogen. Fowl typhoid and pullorum disease are important diseases of poultry but of minimal public health concern. They have been eradicated from commercial operations in the United Kingdom and North America. Since the diseases are rarely seen, readers will find the series of color photographs of pullorum disease particularly useful. Both Newcastle disease and highly pathogenic avian influenza viruses are included in list A of the Office International des Epizooties, and the chapters on these diseases contain ample information related to their prevention and control worldwide. Color photographs show some of the important gross and histological lesions of highly pathogenic avian influenza. Readers will find the comments on human health implications helpful for addressing public concerns. The final chapter on ostrich diseases, alone, would make the book worth having. Information presented on Crimean-Congo hemorrhagic fever, spongiform encephalopathy, and anthrax, as it relates to ostriches, is of public health significance and should interest many readers. In short, I strongly recommend this text for those with an interest in controlling poultry diseases and in preventing zoonotic infections.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
