By understanding the importance of this infection, backyard chicken enthusiasts can take appropriate preventive measures to ensure the health and productivity of their birds.
How Salmonella Pullorum Works in Chickens and Poultry
Salmonella Pullorum causes disease in chickens and poultry through a variety of mechanisms and processes. The transmission of the bacterium primarily occurs through the fecal-oral route, with infected birds shedding the bacteria in their droppings. Other birds within the same environment may then ingest or come into contact with contaminated feces, feed, water, or equipment, leading to the spread of the bacterium within the flock.
Additionally, Salmonella Pullorum can be vertically transmitted, meaning that the infection can pass from infected hens to their offspring via the reproductive system or through contaminated eggs. This can lead to high mortality rates in chicks – often as high as 90% – within the first few weeks of life. Adult birds may show few or no clinical signs of the infection but can still serve as carriers, shedding the bacteria and spreading it within the flock.
Upon infection, the bacterium invades the intestinal tract, causing inflammation, diarrhea, and dehydration. As Salmonella Pullorum spreads systemically throughout the bird, it can affect various organs and tissues, such as the liver, spleen, and heart. Severe infections may result in septicemia, which can be fatal, leading to significant flock mortality and economic losses in affected poultry operations.
