“…Whereas, the morphological criteria about the adult worms and the eggs of capillarid parasite in the present study were in agreement with the studies of Wakelin (1965), Soulsby (1982) and Park and Shin (2010), suggesting it to be C. obsignata. The characteristics features noticed about the adult strongyle worms and the eggs were consistent with Cuvillier (1937), who reported that O. quadriradiatus was pathogenic for domestic pigeons.…”

“…On the other hand, out of the six species of the capillarid nematodes described in the wild and domesticated birds, only two most common species viz. Capillaria obsignata and C. caudinflata have been incriminated to cause pathogenesis in pigeons (Park and Shin, 2010). Heavy infestations of Ornithostrongylus quadriradiatus has been attributed to exhibit acute symptoms rather than characteristic helminthic chronic disease conditions.…”

Out of around 200 pigeons (housed at Mahendra Chaudhury Zoological Park, Chhatbir, Punjab), two pigeons exhibiting signs of depression, lethargy, droopiness and blood tinged greenish diarrhoea were quarantined for detailed examination. The faecal examination revealed a concurrent parasitic egg load of capillarid, ascarid and strongyle eggs. Morphological observations after clearing of retrieved parasites from the deceased pigeons revealed the presence of Ascaridia columbae, Capillaria obsignata, and Ornithostrongylus quadriradiatus. Histopathological studies of the intestines revealed sloughing and hyperplasia of the lining epithelium; whereas kidneys of one of the pigeon exhibited the extensive tubular damage and marked haemorrhages with cut sections of the parasite, Paratanaisia bragai. The other vital organs showed no signs of any significant lesions in both pigeons. This seems to be the first report of fatal concurrent gastrointestinal and renal pathology due to A. columbae, C. obsignata, O. quadriradiatus and P. bragai in pigeons kept at zoological park in India.

“…Enteric Capillariasis caused by B. obsignata is known to occur in all birds belonging to Anseriformes, Ciconiiformes, Columbiformes, Galliformes, Piciformes and Psittaciformes (Jortner et al 1967;Rickard & Pohl 1969;Pinto et al 2004;Pinto et al 2008;Yabsley 2008;Park & Shin 2010;D' Avila et al 2011). There are few reports traced on enteric Capillariasis caused by B. obsignata infections in turkeys, and the severity of the disease was different in each report (Hurst et al 1979;De Rosa & Shivaprasad 1999;Pinto et al 2008).…”

“…Then, the contents from intestinal and cecal lumen were collected in small eppendorf tubes to examine for eggs, oocysts and parasitic load by direct microscopy. The morphological features and morphometry of male and female worms and eggs were assessed to identify the species of parasite as described earlier (Moravec 1982;Moravec et al 1987;Permin & Hansen 1998;Yabsley 2008;Park & Shin 2010;D' Avila et al 2011;Barathidasan et al 2014). The formalin fixed tissues were processed for paraffin embedding and the obtained tissue sections were stained with Hematoxylin and Eosin (H&E) to study the histopathological alterations.…”

“…Severe gastro-enteritis and mortality have been reported due to capillarid worm infections especially in Galliformes (Rickard & Pohl 1969;Baru s & Sergejeva 1989;De Rosa & Shivaprasad 1999;Singh 2010). There are few reports traced on enteric Capillariasis caused by B. obsignata infections in chickens (Jortner et al 1967), turkeys (Hurst et al 1979;De Rosa & Shivaprasad 1999;Pinto et al 2008) and rock partridges (Park & Shin 2010) globally. In India, capillarid eggs have been detected in feces of few turkeys (Singh et al 2006;Das et al 2015).…”

Background: Capillariasis, an important parasitic disease of birds is caused at least by seven different genera of trichurid nematodes with clinical outcome ranging from mild enteritis to high mortality. Objective: This study was aimed to investigate the causative agent involved in high mortality associated with severe enteric illness among turkey flocks in an organized commercial poultry farm at Bareilly, India. Materials and Methods: Turkey carcasses (n D 119) and fecal samples from the affected deep litter pen constituted as the study materials. The disease was investigated by systematic necropsy, direct microscopy and histopathology. Representative samples were screened for other enteric pathogens. Results: Microscopic examination of mucosal scraping revealed capillarid worms and their eggs in all the samples. The morphological features of adult worms were typically consistent to Baruscapillaria obsignata. Histopathology exhibited thickened muscular and mucosal layers, mononuclear and heterophilic infiltration in the lamina propria, blunting and clubbing of villi, epithelial denudation and sections of capillarid worms. Administration of levamisole at 80 ppm in drinking water reduced the mortality, clinical illness and worm load after three days of therapy. Conclusions: The capillarid worms in different avian hosts can cause different clinical manifestations and outcomes. From India, this is the first report describing intestinal pathology caused by B. obsignata in turkeys. We conclude that the B. obsignata infection is capable of causing life threatening enteropathy in turkeys and, hence, routine screening, scheduled deworming and good litter management are crucial to control the infection and its associated loss.
