Bacterial and fungal flora in faecal samples from rooks u Zagrebu, Hrvatska

The objective of this study was to determine the occurrence of bacteria and fungi in populations of urban rooks. We investigated the prevalence of bacteria and fungi in the faeces of rooks (Corvus frugilegus) in the City of Zagreb, during their breeding period in 2006. Microbiological examination of fresh faecal samples revealed the occurrence of Escherichia coli. Bacillus spp., Staphylococcus spp., Streptococcus spp., Agrobacterium radiobacter, and Acinetobacter spp. One rook was positive for Campylobacter jejuni, as confirmed by polymerase chain reaction (PCR). The fungal species Mucor spp., Cladosporium spp., Rhodotorula rubra, Aspergillus (A.) fumigatus and A.flavus, Alternaria sp., Candida spp., and Penicillium spp. were also isolated. Key words: rook, Corvus frugilegus, bacteria, fungi Cilj rada bio je odrediti pojavnost bakterija i gljivica u izmetu vrana gacaca u gradskoj sredini. Istrazivana je pojavnost bakterija i gljivica u svjezem izmetu vrana gacaca (Corvus frugilegus) na podrucju grada Zagreba tijekom razdoblja njihova gnijezdenja u 2006. godini. Mikrobioloskim pretragama, u skladu sa standardnim metodama, iz pretrazenih izmeta izdvojene su bakterije sljedecih rodova: Escherichia coli. Bacillus spp. i Staphylococcus spp., nadalje Streptococcus spp., Agrobacterium radiobacter i Acinetobacter spp. U izmetu jednog gacca postupkom lancane reakcije polimerazom (PCR) dokazana je bakterija Campylobacter jejuni. Iz prikupljenih uzoraka izmeta takoder su izdvojene i gljivice: Mucor spp., Cladosporium spp., Rhodotorula rubra, Aspergillus (A.) fumigatus i A. favus, Alternaria sp., Candida spp. i Penicillium spp. Kljucne rijeci: gacac, Corvus frugilegus, bakterije, gljivice
