Heterakidosis
15
It is a disease of roundworms of the genus Nematoda parasitising the intestine (blind intestine) of poultry: caesars, chickens, turkeys, geese and ducks, and wild birds.
Pathways of infection
Birds are infected with helminth eggs with fodder, i.e. alimentary way. After 1-2 hours, larvae emerge from helminth eggs in the small intestine, and in 24 hours they reach their permanent place of dislocation - the blind intestine, where they continue their development to sexually mature individuals. This will occur about 24 days after infection. The female will lay eggs, which, in turn, with faecal matter will get into the environment. They are very resistant to negative environmental influences. The spread of heterakidosis is indirectly promoted by earthworms, as they consume parasitic eggs, and worms are fed by many birds.
Signs of heterakidosis
The disease is characterised by a chronic course with loss of appetite, strength, activity, constant disorders of the gastrointestinal tract, accordingly, egg production decreases (or completely stops) in adult birds, and young birds show stunted growth and development, cachexia. Very often in hens there is a mixed infestation with other types of nematodes (ascaridosis), then the course of the disease becomes more serious and severe. On poultry farms in places of large accumulation of poultry in unfavourable sanitary-hygienic conditions the disease spreads very quickly, also at joint keeping of different kinds of poultry is widespread overinfestation, especially at unsatisfactory feeding.
Diagnosis and treatment
Diagnosis is made on the basis of characteristic clinical signs and analysis of poultry faeces, where the pathogen is found.
Heterakidosis is treated with ivermectin-containing round helminths such as Praziver.
Observance of sanitary-hygienic norms, timely (daily) cleaning of poultry droppings and their biological disposal plays a huge role in the prevention of the disease, thus preventing the spread of helminthiasis among the poultry population.
