Comprehensive control strategy required to beat salmonella

摘要

Distinction is made between two categories of salmonella infections in poultry; salmonella infections that have a direct negative impact on bird health (Fowl typhoid and Pullorum disease) and salmonella infections of importance to public health (Paratyphoid salmonellae). Salmonellae have a worldwide distribution and generally the goal is to rear poultry salmonella free. This has been achieved in most major poultry producing regions for the poultry specific salmonella pathogens (S. gallinarum and S. pullonuri); however the task to eliminate paratyphoid salmonellae has proved more challenging. The paratyphoid salmonella strains have a very wide host range resulting in a large and continuous source of infection to poultry. This requires a much broaderapproach to control.
