    Avian aspergillosis is reported in several avian species, with Aspergillus fumigatus as the main aetiological agent. Predisposing factors such as starvation, thermal stress, migratory stress, primary infectious disease or toxicosis may play a role. Eight cases of disseminated aspergillosis in free ranging seagulls sheltered at C.R.U.M.A. (Centro Recupero Uccelli Marini e Acquatici, Livorno, Italy) with different clinical histories are presented. The infection was demonstrated by cultural and histological methods from lesions of all birds, and the presence of airborne A. fumigatus viable elements ranging from 450 to 525 CFU/m(3) inside and outside the shelter by means of a surface air sampler (SAS) Super-90 was also assessed. The role of this fungal species as an opportunistic factor in the captivity of seagulls is considered and some control measures, such as a clean and stress free environment and the use of antifungal drugs are suggested

    Three-hundred twenty five droppings from parrots raised in the premises of 4 breeders and in several private households were cultured for yeasts. One-hundred sixty droppings (49.2%) resulted positive. From these specimens 212 isolates belonging to 27 different species were obtained. Mainly Candida species such as C. albicans, C. catenulata, C. curvata, C. famata, C. glabrata, C. guilliermondi, C. holmii, C. intermedia, C. krusei, C. lambica, C. lusitaniae, C. membranaefaciens, C. parapsilosis, C. pelliculosa, C. sake and C. valida were isolated. Debaryomyces marama, D. polymorphus, Geotrichum sp., Pichia etchelsii, P. ohmeri, Rhodotorula glutinis, R. rubra, Rhodotorula sp., Saccharomyces cerevisiae, S. kluyiveri and Zygosaccharomyces sp. were also obtained. Dark colonies on Staib medium were never observed. The psittacine birds apparently serve as carriers for several Candida species or their perfect states and to a lesser extent for other opportunistic yeasts such as Rhodotorula, Trichosporon and Saccharomyces spp., which are considered part of the transient microbiota of the gastrointestinal tract. The most striking finding was the absence of Cryptococcus spp. among the isolates. The present survey confirms the role of pet birds in carrying potential zoonotic yeasts

    PDD: a possibile new therapeutical approach!

    Proventricular Dilatation Disease (PDD) is a deadly wasting syndrome that affl icts wild and domesticated birds and parrots worldwide. The symptoms of PDD are varied, and its outcome is fatal. There is currently no treatment for PDD. The Avian Bornavirus (ABV) is the fi rst candidate in the list of the aetiological agent of PDD. However, the virus was regularly found in clinically healthy birds. This implicates that additional factors for the development of PDD are likely. In our previous studies we have demonstrated that i) sera of PDD-affected parrots showed auto-antibodies to gangliosides; ii) these auto-antibodies are localized in the crop or gastrointestinal ganglia of parrots that, in some cases, are positive also for ABV PCR or P40 antibodies. In our opinion an immunomodulating therapeutical approach is request, for host’s gangliosides antigens desensitization. We report preliminary data regarding a new therapy performed in severely affected birds
