Summary
A study on 13,951 hens found that nearly half of the hens that died had salpingitis, peritonitis, and salpingoperitonitis (sps). Escherichia coli was the primary bacterium identified in affected birds.
Area of Science:
- Veterinary Medicine
- Avian Pathology
- Bacteriology
Background:
- Poultry flocks are susceptible to reproductive tract infections.
- Salpingitis, peritonitis, and salpingoperitonitis (sps) are significant causes of mortality in commercial hens.
Purpose of the Study:
- To investigate the prevalence and causative agents of salpingitis, peritonitis, and salpingoperitonitis (sps) in a commercial hen flock.
Main Methods:
- Postmortem examination of 243 deceased hens from a flock of 13,951.
- Gross examination for signs of inflammation in the oviduct and body cavity.
- Bacterial culture of tissues from 17 birds that died of sps.
Main Results:
- Sps was diagnosed in 111 (46%) of the examined hens.
- Salpingoperitonitis was the most frequent form, followed by salpingitis and peritonitis.
- Escherichia coli was isolated from all 17 cultured birds, often with other bacteria.
Conclusions:
- Sps is a common condition in commercial laying hens, with E. coli being a key pathogen.
- Prompt bacterial culture is crucial for identifying causative agents in poultry mortality cases.
