Colibacillosis is a bacterial infection caused by strains of Escherichia coli ( E. coli ), particularly in poultry and swine farming, but it can also affect humans. It commonly manifests as diarrhoea and is a significant concern in newborn piglets. The impact of colibacillosis on piglets includes economic losses due to reduced growth rates, increased mortality, and cost of treatment. It can also lead to secondary infections if not treated promptly. To control the outbreak of colibacillosis, effective management, good biosecurity, herd health and hygiene, as well as early intervention are crucial. E. coli is a diverse group of bacteria, and while many strains are harmless, some can cause illnesses in animals and humans. In commercial pig production, E. coli can be a concern due to its potential to cause diseases such as colibacillosis. Colibacillosis in pigs is often associated with strains of E. coli that can cause various clinical conditions, including diarrhoea, respiratory issues, and systemic infections. Factors such as crowded living conditions, poor sanitation, and stress can contribute to their spread within pig farms While it is important to realise the economic implications of these detrimental bacterial infections, more pressingly, we must consider the prevention and treatment of these challenges in the future. Widespread antibiotic use in animals, as well as improper usage in humans, can cause bacteria to develop resistance against antibiotics. This is referred to as antimicrobial resistance (AMR). Responsible antibiotic use starts with a hands-on, targeted approach, which includes good management, early detection and appropriate treatments, to name a few. Before treatments can be administered, producers and staff must recognise signs and symptoms of economically important bacterial infections, such as colibacillosis.
