Salpingitis is the inflammation of the oviduct, usually associated with an infection, sometimes peritonitis. It can be caused by a wide variety of bacterial organisms, however it most frequently involves Escherichia coli
(Colibacillosis), Pasteurella multocida
), or Riemerella anatipestifer
) in ducks.
Salpingitis can occur in acute or chronic form. Common causes of salpingitis include other reproductive system conditions such as egg binding or oviduct impaction. The oviduct is one of the main organs within a female duck's reproductive system. It is a long twisted tube through which an ovum (egg) passes from the ovary. The oviduct is equivalent to the fallopian tube in woman. Initially ducks may not show any signs of infection, but will begin to lay fewer eggs and in some cases may stop laying eggs altogether. This has an internal impact on the bird, as the partially produced egg material (shell, yolk, membranes, etc.) that would normally develop into an egg will start to accumulate within the oviduct. The oviduct is only so large, and when it can no longer fit anymore egg material it will start to spill out and into the duck's body cavity.
