    BACKGROUND: This study aimed to evaluate the effects of selenium nanoparticles (SeNPs) and/or vitamin E (VE) on the growth, body composition, metabolic parameters, histopathology, and resistance of Nile tilapia to Aspergillus flavus.

    RESULTS: Monosex Nile tilapia fingerlings were sourced from the Bazina farm and hatchery in Ismailia Governorate, Egypt, where the experiment was also conducted. The fish were acclimatized for 15 days before the trial. A total of 240 fingerlings (average weight 46 ± 3.0 g/fish) were divided equally across 12 concrete tanks (1 × 1 × 1.2 m, 1 m³ capacity), with 20 fish per tank. The fish were fed a control diet (T0), which was a basal diet with no supplementation, or one of three experimental diets for 60 days: T1 (1 mg SeNPs/kg), T2 (100 mg VE/kg), and T3 (1 mg SeNPs + 100 mg VE/kg). The experiment followed a completely randomized design (CRD) with three replicates per treatment. The combination of SeNPs and VE (T3) resulted in the best feed conversion ratio. A slight but significant increase (P

    Spontaneous fatal aspergillosis occurred in several species of parrots imported from Latin America, Australia, Malaya and Ghana for studies on the control of psittacosis. Over a period of 4 years, 655 parrots were imported for use in these studies. All birds that died during these investigations were necropsied, and the internal organs of 45 were found to have macroscopic lesions suggestive of aspergillosis. Of these 45 suspected cases, 32 were confirmed as aspergillosis by both histopathology and culture, and three others by histopathology alone. There was no evidence that the remaining 10 had this disease. Of the 32 culturally confirmed cases, 13 were found to be caused by Aspergillus fumigatus, 16 by A. oryzae, and three by both fungi. In this series, three sets of circumstances appear to have been associated with the development of fatal aspergillosis. Their capture and transport to the United States, the administration of chlortetracycline used in the control of psittacosis, and the administration of cortisone acetate in an attempt to activate existent latent psittacosis infections. The possible causal relationship of these factors are discussed.
