Poult enteritis complex (PEC) is a multifactorial disease in young turkeys, causing stunting and poor feed utilization. Prevention focuses on biosecurity and cleaning to minimize economic losses in commercial turkey production.

Area of Science:

  • Veterinary Pathology
  • Poultry Disease Research
  • Infectious Disease Epidemiology

Background:

  • Poult enteritis complex (PEC) is an umbrella term for infectious intestinal diseases in young turkeys.
  • While some PEC components are understood, others like transmissible viral enteritis remain poorly defined.
  • All PEC forms are multifactorial, infectious, and transmissible, leading to enteritis, stunting, and poor feed conversion.

Purpose of the Study:

  • To provide a comprehensive overview of poult enteritis complex (PEC) in turkeys.
  • To describe the clinical features, pathogenesis, transmission, and economic impact of PEC.
  • To outline current strategies for prevention and control of PEC.

Main Methods:

  • Review of existing literature on poult enteritis complex.

Related Experiment Videos

  • Analysis of clinical signs, gross and microscopic lesions associated with PEC.
  • Discussion of etiological agents, pathogenesis, and contributing non-infectious factors.
  • Evaluation of transmission routes, diagnostic challenges, and control measures.

    • Main Results:

    • PEC presents with non-specific enteritis, stunting, poor feed utilization, and potentially immune dysfunction and mortality.
    • Pathogenesis involves viral enterocyte infection, inflammation, and secondary bacterial proliferation.
    • Diarrhea is primarily osmotic due to maldigestion/malabsorption, with a possible secretory component.
    • Transmission is mainly fecal-oral; no public health significance is identified.

    Conclusions:

    • Effective prevention of PEC relies on stringent biosecurity, cleaning, and disinfection protocols.
    • Control strategies may necessitate regional coordination and quarantine for severe outbreaks.
    • Current treatment is supportive, with antibiotics aiding secondary bacterial infections; no vaccines are available.
    • PEC causes significant economic losses in the turkey industry due to impaired growth and performance.
