Salpingitis is the inflammation of the oviduct which occurs commonly in adult laying hens. It is most frequently caused by bacterial infection ascending from the vent and cloaca but can also be associated with respiratory and systemic infections.

Escherichia coli is the most common pathogen responsible for causing the infection, others include Mycoplasma, Pasteurella, Streptococcus and Salmonella. Newcastle disease, Avian influenza, and Infectious bronchitis have also been associated with salpingitis in chickens.

The estrogenic activity involved in the process of egg laying facilitates the migration of infectious pathogens from the cloaca to the oviduct. Once the bacteria gain access to the oviduct, it can penetrate the oviduct wall or travel through the open end of the infundibulum and enter the abdominal cavity, resulting in peritonitis.

Clinical Signs of Salpingitis in Chickens

Clinical signs of salpingitis in hens are often vague and can be difficult to detect during the early stages of the infection. Early-stage signs typically include mild depression and decreased egg production. Hens may produce abnormally shaped eggs.

Clinical signs observed during the advanced stages of salpingitis are usually associated abdominal distension resulting from oviduct impaction or rupture, coelomitis or septicemia.

Clinical Signs

Laying abnormal or malformed eggs
Decreased egg production
Reduced appetite
Distended abdomen
Standing with a “penguin-like” posture
Difficulty walking or perching


  • Egg laying history
  • Ultrasound
  • Radiographs
  • Coeliotomy (surgery)


Supportive careIsolate the bird from the flock and place in a safe, comfortable, warm location (your own chicken "intensive care unit") with easy access to water and food. Limit stress. Call your veterinarian.
SurgeryMost cases require surgery, to remove the accumulated egg material, and usually followed by a salpingohysterectomy (removal of the oviduct). Followed by antibiotics and anti-inflammatories.
AntibioticsChosen based on culture and sensitivity results.
Hormone implantsSuprelorin® (deslorelin) to help stop future ovulation.
