Protect your chickens from colibacillosis (E. coli)
Whether you are running a breeding operation, broiler, or layer farm, virtually every Canadian producer has dealt with E. coli.
Escherichia coli bacteria are natural residents in the poultry gut, normally kept in balance by beneficial gut microflora. However, when large colonies form or systemic infection occurs, E. coli can cause severe discomfort, colibacillosis, reduced feed conversion, and increased mortality. Keeping E. coli in check is essential to safeguarding animal welfare and maintaining flock performance.

What causes E. Coli in chickens?
The illness caused by pathogenic Escherichia coli is referred to as colibacillosis. E. coli is naturally present in the intestinal tract of poultry and is generally harmless. However, some strains are pathogenic, producing toxins and other virulence factors (VFs) that damage the host's cells. E. coli infections are most likely to occur when birds experience underlying health issues or environmental stress:
- Secondary infections
- Weakened immune system
- Weakened intestinal barrier
- High pathogenic pressure from the environment.
How does colibacillosis spread on the farm?
Infected birds can spread E. Coli via feaces, eggs or via the airways.
- Cloaca: the orbicular muscle between the vagina and cloaca can relax too much, so that fecal particles with E. coli can reach the vagina and fallopian tube.
- Intestinal wall: E. coli can get into the abdominal cavity via the intestinal tract and the intestinal wall.
- Airways: E. coli bacteria can get in the fallopian tubes and abdominal cavity via the air bags.
- Via the parent stock: In the egg through contaminated fallopian tubes or contaminated shell.
- Via drinking water: Drinking water is an important source or way to spread e.coli throughout your operation.

What are the symptoms of E. coli in chickens?
Signs are nonspecific and vary with age, organs involved, and concurrent diseases.

- Ruffled feathers
- Depression
- Less feed intake and higher conversion
- Coughing
- Yellowish coloured diarrhea
- Difficulty breathing

How to protect chickens against E. coli infections
The goal is to reduce the likelihood of problematic growth of E. coli. This can be achieved by minimizing the disease burden on animals.
As a poultry farmer, your best defense is to ensure thorough and regular cleaning and disinfecting of your birds' housing and by providing clean drinking water. These crucial steps significantly reduces the risk by decreasing pathogenic pressure on your animals.
In addition, closely monitoring stress levels and addressing secondary infections will significantly reduce the chances of Avian Pathogenic Escherichia coli (APEC) infection. It is important to remember that the health of your flock relies on effective farm management.
The 5 steps to prevent E. coli in chickens
In order to prevent E. coli infections in chickens, it is crucial to address and eliminate potential risk factors. Let's explore the five biosecurity measures that can effectively tackle E. coli.:format(webp))
Guard your poultry: hygiene is key
Experts strongly recommend implementing hygiene protocols to protect your poultry from E. coli. It is crucial that every person thoroughly washes and showers before entering the farm to ensure the safety and well-being of your poultry, guarding them against any unwanted guests.:format(webp))
