Interpretive Summary: Technical Abstract: The numerous motile members of the bacterial genus Salmonella are collectively referred to as paratyphoid (PT) salmonellae. Found throughout the world, these organisms infect a wide variety of hosts (including invertebrate and vertebrate wildlife, domestic animals, and humans) to yield either asymptomatic intestinal carriage or clinical disease. First reported in avian species in an 1895 infectious enteritis outbreak in pigeons, PT infections have a long history of association with significant disease losses in young poultry. PT salmonellae have also emerged as leading agents of food-borne human disease, and contaminated poultry meat and eggs are frequently implicated as vehicles for Salmonella transmission. Advances in poultry production practices, changes in consumer lifestyles and preferences, and heightened nutritional awareness have all helped to establish poultry products among the principal sources of animal protein for much of the world. Accordingly, preventing (or at least controlling) PT infections in poultry flocks has become an important objective from both economic and public health perspectives. |
