Aspergilosis en Ganso Silvestre (Chloëphaga poliocephala Scl., 1857) en Chile

Abstract

Summary Aspergillosis in Wild Goose (Chloëphaga poliocephala Scl., 1857) in Chile The first report of Aspergillus fumigatus in wild goose (Cloëphaga poliocephala Scl., 1857) in the South of Chile is presented. The diagnosis was carried out considering the anatomo‐pathological characteristics of the lesions and the isolation identification of the aethiological agent according to Thom and Raper's methodology. Resumen Se comunica el primer hallazgo de Aspergillus fumigatus en ganso silvestre (Chloëphaga poliocephala) en el sur de Chile. El diagnóstico fue realizado considerando características anatomopatológicas de las lesiones presentes y aislamiento e identificación del agente etiológico mediante la clave de Thom y Raper (1945). Zusammenfassung Aspergillose bei Wildgänsen (Graukopfgans, Chloephaga poliocephala Scl., 1857) in Chile Es wird der erste Fall von Aspergillus‐fumigatus‐Mykose bei einer Wildgansart (Graukopfgans, Chloephaga poliocephala) im Süden Chiles mitgeteilt. Die Diagnose wurde aufgrund pathologischanatomischer Befunde und durch Isolierung und Identifizierung des ätiologischen Agens mittels des Schlüssels von Thom und Raper (1945) gestellt.

Immunohistochemical detection of fungal elements in the tissues of goslings with pulmonary and systemic aspergillosis

“…Gross postmortem examination of the goslings showed variously sized yellowish-white nodules scattered throughout the lungs and within the air sacs, in accordance with observations made on other avian species (Hawkey et al, 1984;Reece et al, 1986;Ulloa et al, 1987;Bowes, 1990;Flach et al, 1990;Pandita et al, 1991;Machin et al, 1993). In some cases, a large portion of the lung lobes was obliterated by large coalesced granulomas, as observed previously in Stellar's jays (Machin et al, 1993), turkeys (Dyar et al, 1984) and chickens (Chaudhary and Singh, 1983).…”

“…In the literature, however, aspergillus granulomas have rarely been reported in the abdominal viscera of geese (Ulloa et al, 1987), as in other avian species (Pal et al, 1989). It is well known that aspergillosis results mainly from inhalation of spores of the fungus, commonly found in the environment (Hawkey et al, 1984;Reece et al, 1986;Pal et al, 1989;Bowes, 1990;Richard, 1991;Machin et al, 1993;Singh et al, 1993).…”

“…In this study, all of the goslings investigated were found to have the respiratory lesions of aspergillosis, with involvement of the lungs and air sacs. However, there is a paucity of information on systemic aspergillosis in geese (Ulloa et al, 1987), as in other birds (Pal et al, 1989;Bowes, 1990;Pandita et al, 1991), although the disease has been documented in sheep (Perez et al, 1998), cattle and humans (Buckley et al, 1992). Our study found systemic aspergillosis in 7 cases, with distribution of the nodules to the serosal linings and parenchymal organs of the abdominal cavity, bursa of Fabricius and m. longus colli along with lesions in the lungs and air sacs.…”

“…Key words: Immunohistochemistry, goslings, fungal elements, aspergillosis Aspergillosis, defined as any disease caused by a member of the fungal genus Aspergillus, has been documented in many avian species (Richard, 1991;Carrasco et al, 1998) including the goose (Ulloa et al, 1987;Okoye et al, 1989;Turkutanit, 1999). Of all the fungal diseases, aspergillosis encompasses the broadest range of pathogenic mechanisms and clinical presentations, as Aspergillus species are common in the environment (Hawkey et al, 1984;Piérard et al, 1991;Machin et al, 1993;Singh et al, 1993).…”

Outbreak of aspergillosis in a flock of geese in Zaria, Nigeria

“…The disease was recognized as an avian disease since 1815 and generally involves the respiratory tract (Beytut et al, 2004;Marina et al, 2004). The principal agent causing aspergillosis in poultry is A. fumigatus, which accounts for 66 % of the Aspergillus species isolated from geese (Ulloa et al, 1987;Ziolkowska & Tokarzewski, 2007). Isolation of A. versicolour, and A. flavus is less common (Ziolkowska & Tokarzewski, 2007;Jezdimirovic et al, 2013).…”
