A flock of 3-week-old broiler chickens fed with antibiotic-free commercial feed developed cyanotic combs, depression, extended abdomens, reddened abdominal skin, faeces-stained vents, and diarrhoea. By the end of week 6, mortality reached 19.3%, and important lesions seen were ascites, airsacculitis, swollen/congested kidneys, fibrinous perihepatitis, fibrinous pericarditis with or without hydropericardium, haemorrhagic enteritis-typhilitis and ballooned caeca. Salmonella typhmurium var Copenhagen and Escherichia coli were isolated from livers, hearts, intestines and caeca. Histomonas spp. were detected only in caeca. Thus, concurrent occurrence of salmonellosis, colibacillosis and histomoniasis was diagnosed.
Lemdana latifi n . sp . was found in connective tissues around the trachea and crop and in the body-cavity of seven of 14 Malayan red jungle fowl Gallus gallus spadiceus . The new species is described and illustrated . Morphologically it is most closely related to Lemdana pavonica and Lemdana francolini .Lemdana latifi is distinguished from the eight valid species of Lemdana by the mean spicular ratio of 1 .7 :1 ; the right spicule with a right margin 18-29% (15-31 gm ; mean 24 gm) longer than the left margin ; the distal half of the left spicule twisted and S-shaped ; and the absence of unpaired papillae at tip of male tail . The new species has smaller adults, a shorter left spicule and a shorter glandular oesophagus than those of L . pavonica and a wider male, shorter spicules and a longer muscular oesophagus than those of L . francolini . The male of L . latifi is 7-9 (8 .1)mm long, the left spicule 164-215 (184)µm long and the right spicule 98-117 (108)µm long . The female is 17-23 (21)mm in length . Sheathed microfilariae from blood smears are 78-100 gm long and those from the uterus are 89-103 gm long . This is the sixth valid species of Lemdana in the Phasianidae .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
