En la obra podemos visualizar la caracterización de las diversas modalidades históricas que dieron origen a la bacteriología en Colombia: la llegada de médicos e investigadores en la época de la Colonia que sembraron la semilla de los servicios en el campo de la salud. La creación de escuelas y facultades de medicina, hospitales gubernamentales y laboratorios privados donde la Bacteriología se imagina, crea, forma y crece en el pensamiento, el ansia de conocimiento y la ardua labor investigativa del cuerpo médico tanto nacional como extranjero. (Cilia Rojas de Molano)
This book summarizes the development and statistical validation of a guinea pig model as an alternative for potency testing of the viral antigens included in combined vaccines applied in cattle to control the respiratory, reproductive, and neonatal calf diarrhea syndromes. The model allows, in one serum sample, to test the vaccine quality for all the viral antigens included in aqueous as well as in oil-adjuvanted formulations of bovine vaccines. The methodology proposed for the control of bovine herpes virus, parainfluenza, and rotavirus were recommended by CAMEVET as guidelines for the 30 countries in the forum, including the US. Key Features Reviews combined vaccines used for cattle Summarizes animal models used for vaccine testing Focuses on bovine herpesviruses, rotaviruses, parainfluenza, and bovine viral diarrhea virus Provides guidance on the effectiveness of the Guinea Pig model for testing vaccine immunogenicity
Food safety awareness is at an all time high, new and emerging threats to the food supply are being recognized, and consumers are eating more and more meals prepared outside of the home. Accordingly, retail and foodservice establishments, as well as food producers at all levels of the food production chain, have a growing responsibility to ensure that proper food safety and sanitation practices are followed, thereby, safeguarding the health of their guests and customers. Achieving food safety success in this changing environment requires going beyond traditional training, testing, and inspectional approaches to managing risks. It requires a better understanding of organizational culture and ...
Currently, there is no one book or textbook that covers all aspects of retail food safety. It is becoming apparent that a number of issues relating to retail food safety have come to the forefront in some jurisdictions of late. For example, a recent USDA risk assessment has pointed out that issues occurring at USA retail appear to be critical in terms of contamination of deli-meat. As well, a large listeriosis outbreak in Quebec pointed to retail cross-contamination as a key issue. In terms of sanitation, a number of advances have been made, but these have not all been synthesized together in one chapter, with a focus on retail. In addition, the whole area of private standards and the Global Food Safety Initiative (GFSI) have come to the forefront of late and these as well will be explored in great detail. Other aspects related to the safety of important food commodities such as seafood, meat, produce and dairy will also be discussed and salient areas addressed.

In this book, some of the most qualified scientists review different food safety topics, ranging from emerging and reemerging foodborne pathogens, food regulations in the USA, food risk analysis and the most important foodborne pathogens based on food commodities. This book provides the reader with the necessary knowledge to understand some of the complexities of food safety. However, anybody with basic knowledge in microbiology will find in this book additional information related to a variety of food safety topics.
Foodborne illnesses continue to be a major public health concern. All members of a particular bacterial genera (e.g., Salmonella, Campylobacter) or species (e.g., Listeria monocytogenes, Cronobacter sakazakii) are often treated by public health and regulatory agencies as being equally pathogenic; however, this is not necessarily true and is an overly conservative approach to ensuring the safety of foods. Even within species, virulence factors vary to the point that some isolates may be highly virulent, whereas others may rarely, if ever, cause disease in humans. Hence, many food safety scientists have concluded that a more appropriate characterization of bacterial isolates for public health ...
