Symptoms

  • Chickens:
    • Bloody diarrhea
    • Decreased feed intake
    • Weight loss/poor growth
    • Ruffled feathers
    • Pale comb and wattles
    • Huddling and depression
    • Dehydration
  • Turkeys:
    • Watery/mucoid droppings
    • Reduced weight gain
    • Lethargy
    • Poor feed conversion
    • Intestinal inflammation
  • Waterfowl:
    • Generally more resistant
    • Mild diarrhea
    • Slight weight loss
    • Less severe symptoms

Causes and modes of transmission

  • Causative Agent:
    • Species-specific Eimeria parasites
    • Multiple species affecting different intestinal regions
    • Highly resistant oocysts
  • Transmission:
    • Fecal-oral route
    • Contaminated litter
    • Equipment and boots
    • Wild birds
    • Mechanical vectors

Prevention strategies

  • Management:
    • Proper ventilation
    • Avoid overcrowding
    • Clean water supply
    • All-in-all-out systems
  • Medication:
    • Anticoccidial programs
    • Probiotics programs
    • Rotation of medications

Treatment options

  • Immediate Action:
    • Anticoccidial medication
    • Electrolyte supplementation
    • Vitamin A supplementation
    • Stress reduction
  • Supportive Care:
    • Clean, dry environment
    • Fresh water access
    • Balanced nutrition
    • Temperature control

Conclusion: Resistance to anticoccidial drugs is an increasing concern, making prevention and management crucial for control.
