Poultry disease

[Dr Yamna Ahmad]

Histomonasis (black head disease)

Caused by : H.melegridis

Symptoms: yellow sulfur color droppings , dropping wings (turkeys)

slight weight loss and reduced egg production (chickens)

Transmission: cecal worm (Heterakis gallinarium)

litter feces and infected birds

Prevention & control :

1.Biosecurity

2.deworming

3.Sanitation

4.Litter management

5.Vaccination

Histomoniasis, also known as blackhead disease, in poultry is characterized by symptoms like listlessness, reduced appetite, drooping wings, unkempt feathers, and sulfur-colored droppings, with no approved vaccines or treatments currently available, though effective biosecurity and hygiene practices can help minimize its impact.

Histomoniasis, also known as blackhead disease, in poultry causes symptoms like listlessness, reduced appetite, drooping wings, and sulfur-colored droppings. While there’s no specific cure, effective biosecurity, hygiene, and targeted deworming can help minimize the impact of the disease. <div>Here’s a more detailed explanation:</div><div>Symptoms:</div><div>General Signs:</div><div>Listlessness and depression </div><div>Reduced appetite and poor growth </div><div>Drooping wings and unkempt feathers </div><div>Increased thirst </div><div>Yellow or sulfur-colored droppings </div><div>Specific to Turkeys:</div><div>Ruffled feathers, drooped wings, and apathy </div><div>Young turkeys may die within a few days of signs appearing </div><div>Specific to Chickens:</div><div>Clinical signs in chickens may be less clear than in turkeys </div><div>Body weight uniformity can be affected during the rearing period, and a drop in egg production can occur </div><div>Post-mortem findings:</div><div>Enlarged caecae (blind gut) </div><div>Typical lesions in the liver, often described as “target” or “bullseye” lesions </div><div>Thickened caecal walls, often ulcerated and hemorrhagic </div><div>Yellowish dry, cheesy material (caecal cores) in the lumen of the caeca </div><div>

1. General Symptoms: reduced appetite, dropping wings, lethargy

2. Digestive Symptoms: Yellow, sulfur-colored diarrhea, weight loss, inflammation of the cloaca

3. Liver and cecal Lesions (post-mortem signs): enlarged liver with yellow or green lesions, enlarged cecum with caseous (cheesy) material

Supportive treatment:

Broad-spectrum: (e.g., Tylosin, Oxytetracycline) to prevent bacterial infections.

Electrolytes and vitamins (A, C, E, K): to boost immunity and recovery.

Probiotics and organic acids: to improve gut health and reduce protozoal load.

Herbal remedies: (e.g., garlic extract, neem, turmeric) may help suppress <em data-start=”2021″ data-end=”2045″ style=”background-color: var(–bb-content-background-color); font-size: inherit; color: var(–bb-body-text-color);”>Histomonas meleagridis.

Biosecurity measures:

Separates chickens from turkeys: Chickens can carry <em data-start=”2144″ data-end=”2156″ style=”font-size: inherit; color: var(–bb-body-text-color); background-color: var(–bb-content-background-color);”>Histomonas without severe symptoms but spread it to turkeys, where it is often fatal.

Deworming: The disease spreads through cecal worms which carry the parasite. Use fenbendazole or albendazole to reduce transmission.

Disinfection of poultry houses: Use lime or ammonia-based disinfectants to kill <em data-start=”2518″ data-end=”2530″ style=”background-color: var(–bb-content-background-color); font-size: inherit; color: var(–bb-body-text-color);”>Histomonas in the environment.

Avoid wet or contaminated litter: Histomoniasis spreads in moist conditions.

Drooping head and wings, prolonged standing, closed eyes, ruffled feathers, emaciation, and sulfur colored feces.

Dropping excreta, reduce feeding, swollen ceca & liver lesions.
