Lorin, Daniela; Teusdea, Valer; Mitranescu, Elena; Danes, Mihai; Stef, Lavinia ; Mosneang, Crina Laura; Cristina, Romeo Teodor. The mycobiota composition in eight Romanian representative poultry and swine farms. Romanian Biotechnological Letters, 22(5), pp. 12961-1297, 2017.

Abstract: Although significant studies have been conducted, only few reported comparatively in one study, the fungal structure on poultry and swine units. The investigation describes the fungal species relative abundance in a longitudinal up dated survey, in four poultry and four swine units. The aim of the study was to characterize the mycobiota and those strains with known pathogenic importance to animal and human health, presented comparatively in 250 samples of feed, air, water, bedding, floor and surface. Results revealed a diverse mycoflora, the isolation describing a filamentous fungi and yeast mosaic: Aspergillus, Penicillium, Mucor, Absidia, Rhizopus, Alternaria, Ulocladium, Cladosporium, Fusarium and respectively Rhodotorula and Candida. From a total of 544 fungi strains, 231 (42.5%) were represented by Aspergillus spp, 158 (29.1%) and Candida spp, 72 (13.4%), fact that permitted to ascertain that these fungi were the most frequently and possible involved in the animal pathologies in units. Concluding, the study suggests that contamination of animals breeding environment isn't due to a single source, confirming high diversity of environmental fungal isolates. The isolation and identification methodology presented could be, from our perspective, a helpful tool to understand and imagine the most appropriate and coherent steps in future antifungal strategies.
