Abstract
The aim of this preliminary study was to identify microorganisms with antimicrobial resistance profile and biofilm producers in oropharynx of Rupornis magnirostris and Caracara plancus. Six R. magnirostris and six C. plancus maintained in Triage Center for Wild Animals (CETAS) facilities were studied. Coagulase-positive staphylococci (CoPS), enterobacteria, and yeasts were identified by the biochemical analysis or MALDI-TOF mass spectrometry. The resistance profile of the microorganisms was analyzed according to CLSI. The biofilm production was evaluated by Congo red and violet crystal staining methods. Among the 12 birds, 10 presented strains of CoPS and/or enterobacteria with resistance profile, such as methicillin-resistant CoPS (MR-CoPS), vancomycin-resistant CoPS (VR-CoPS), extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL), and Klebsiella pneumoniae carbapenemase- (KPC-) producing bacteria. Regards the fungal analysis, Candida spp., Cryptococcus spp., Rhodotorula mucilaginosa, R. glutinis, and Trichosporon coremiiforme were identified. All the Trichosporon coremiiforme strains were resistant to amphotericin B, as well as all the Rhodotorula mucilaginosa exhibited resistance to fluconazole. Related to the biofilm production, among the 8 CoPS, 27 enterobacteria, and 10 yeasts isolates, 3, 16, and 7 strains were biofilm producers, respectively. Thus, the presence of these microorganisms in birds of prey is worrisome, highlighting its possible influence in the spread of infections in urban centers.

Regarding the antimicrobial resistance profiles analyzed, the concomitant profile MRand vancomycin-resistant CoPS (VR-CoPS) were identified in 50% of the samples; only the profile methicillin-resistant CoPS (MR-CoPS) was present in 12.5%, and 37.5% of the CoPS isolated from the oropharynx of the birds was antibiotic-sensitive

Academic Editor: Francesca Mancianti e aim of this preliminary study was to identify microorganisms with antimicrobial resistance profile and biofilm producers in oropharynx of Rupornis magnirostris and Caracara plancus. 1. Introduction e hawk-carijo (Rupornis magnirostris) and the carcara (Caracara plancus) belong to the orders Falconiformes and Accipitriformes, respectively. Introduction e hawk-carijo (Rupornis magnirostris) and the carcara (Caracara plancus) belong to the orders Falconiformes and Accipitriformes, respectively Both species are widely distributed throughout the Americas, mainly in South America, and are well distributed in the Brazilian territory [1]. Our research group has identified Enterobacteriaceae with resistance profile in rectal swabs present in gavião-carijo (Rupornis magnirostris), among them, E. coli, K. pneumoniae, and Salmonella spp. are resistant to ciprofloxacin and lots of beta-lactams [8]. Our research group has identified Enterobacteriaceae with resistance profile in rectal swabs present in gavião-carijo (Rupornis magnirostris), among them, E. coli, K. pneumoniae, and Salmonella spp. are resistant to ciprofloxacin and lots of beta-lactams [8]. ese animals, besides being affected by infections caused by these microorganisms, can become reservoirs and potential disseminators of these agents owing to their migratory capacity [6,7,8,9]
