Causes of fatal cyathostomiasis in brown booby (sula leucogaster) from brazil: identification of pathogen and implications for management.

CAUSES OF FATAL CYATHOSTOMIASIS IN BROWN BOOBY (SULA LEUCOGASTER) FROM BRAZIL: IDENTIFICATION OF PATHOGEN AND IMPLICATIONS FOR MANAGEMENT. J Parasitol. 2020 Apr 07;: Authors: Cardoso RNR, Baldassin P, Jerdy H, Carvalho EC, Kanarek G, Zaleśny G, Werneck MR Abstract Fatal infection by Cyathostoma ( Cyathostoma ) phenisci Baudet, 1937 (Nematoda: Syngamidae) was identified in two out 52 brown boobies ( Sula lecucogaster Boddaert, 1783) collected on beaches in the state of Rio de Janeiro, Brazil, and admitted to the veterinary clinic for rehabilitation. Both infected birds were in poor physical condition, with atrophied pectoral muscles, and died soon after starting treatment. The parasitological and pathological examination of the carcasses revealed the presence of C. (Cyathostoma) phenisci in the trachea, resulting in tracheitis, as well as severe parasitic granulomatous bronchopneumonia caused by eggs deposited in the lungs. In our opinion, these serious pathological changes were the primary cause of the chronic respiratory illness. This is a first description of fatal cyathostomiasis in a fish-eating avian host caused by infection by a member of the subgenus Cyathostoma (Cyathostoma) . Therefore, it is reasonable to consider C. (Cyathostoma) phenisci to be a real threat to a wide range of their definitive hosts and cyathostomiasis should be considered in the differential diagnosis for fish-eating marine birds, even in cases without r...
