Abstract
Study on prevalence and tissue pathology associated with the Gizzard worm - Cheilospirura (Acuaria) hamulosa (Nematoda, Acuarioidea) was carried out for a period of two years from Jan 2016 to Dec 2017. The study was conducted on a sample size of 240 gizzards obtained from the indigenous backyard fowl collected from different localities of Kashmir valley of J&K state, India. The investigation revealed annual prevalence of the nematode for 1st and 2nd yr of study to be 5% (6/120) and 3.3% (4/120), respectively, with an overall prevalence of 4.16% (10/240). Parasitic burden was found to be low (1-2) but in spite of the low parasite burdens, the gross lesions induced by C. hamulosa were severe leading to haemorrhages, ulcerations and yellow nodules on caudoventral muscle of gizzard. Histological examination of the infected gizzard revealed discrete and coalescing, nodular and cystic lesions and granulomas in muscularis, submucosa and serosa of gizzard which contained sections of the parasite. Cellular reaction in the lesions was characterized by infiltration of large number of lymphocytes, monocytes, plasma cells, heterophils, and, in some of the sections, severe eosinophilic reaction was observed. The mucosa and submucosa showed mononuclear infiltration as well as reactive lymphoid nodules.
