A note on concurrent natural parasitism by Dispharynx spiralis and Heterakis gallinarum in backyard poultry (Gallus domesticus)

Abstract

The nematodes Dispharynx spiralis (Superfamily-Spiruroidea, Family-Acuariidae) parasitising the proventriculus and Heterakis gallinarum (SuperfamilySubuluroidea, Family-Heterakidae) found in the caecum of two backyard poultry birds are described. The usual location of D. spiralis is glandular stomach or proventriculus, where their heads may be deeply buried in the proventricular wall. H. gallinarum occurs in the caecum and commonly called as caecal worm of poultry.
