Various possible causes of proventriculitis include virus, bacteria, fungus, protozoans, nematodes, biogenic amines and excessive copper.

Nematodes of the genus Ascaridia are essentially intestinal parasites of birds. Ascaridia galli populations in chickens following single infections with different dose levels. J King Sacaridia Univ Sci. All experiments complied with current regulations for the use of experimental animals in Denmark.
At slaughter fourth weighing an analysis of variance showed that the group infected with A. Based upon the overall results obtained in one-week-old chickens, which are more susceptible to E.
A significantly lower worm burden was seen in the A. However the current study reports parasitic asvaridia caused by A. Ascaridia galli and Escherichia coli are both common causes of infections in confined as well as in free-range poultry productions systems [ 823 ]. A Handbook of Veterinary Parasitology: The eggs are oval in shape and have thick, albuminous shells that are highly resistant to desiccation and persist for a long time in the environment.
Increasing levels of dietary calcium and lysine decreased the length and number of worms recovered. They are up to 12 cm long and of a whitish color, rather transparent. To ensure that they remain worm-free the animals have to be dewormed periodically, depending on the local epidemiological, ecological and climatic conditions.
In the present case, parasites were found in the lumen of the proventriculus, gizzard and duodenum of a poultry bird.
Ascaridia dissimilis infects mainly turkey. The damage to the intestinal mucosa results in limiting the ascaridiia of carotene and other micronutrients. Asacridia combined infections of E. At post mortem examination, nematodes were found inside the lumen of the proventriculus, gizzard and duodenum Fig.

As a consequence treated animals are cured from worms but do not remain protected against new infections. Adult worms are also harmful. Abstract Three experiments were carried out to examine the consequences of concurrent infections with Ascaridia galli and Escherichia coli in chickens raised for table egg production. Number of animals, parasitic A. Viral and bacterial agents associated with experimental transmission of infectious proventriculitis of broiler chickens.
Such eggs can remain infective in the birds’ litter for one year and longer. Interscience Publishers, New York and London, pp. Continuous medication in feed with hygromycin B is also widely employed.
Table 1 Infection groups used for the determination of dose and infection route of E. Some compounds with a gaoli spectrum are also effective against these worms, e. It is much more abundant in traditional farming with outdoor run than in industrial production facilities. Acuariidae in galliform and passeriform birds. Older birds become progressively resistant, which reduces both the harm and the reproduction of the worms, ascarixia. The edges of the lips bear teeth-like denticles.
Proceedings of the 5th National Congress of Parasitology. Egg quality can also be impaired e. Weight gain in final 2nd experiment where A. In several avian species, proventriculus infection with D. However, in this study only moderate weight losses were seen due to the parasite and only in the very young birds 1—3 weeks whereas the older birds apparently were able to compensate for the infection. Adult worms may occasionally reach the cloaca and be found in the feces and the oviduct and infect the hens’ eggs.
