“…aureus strain was isolated from the oral cavity of a racing pigeon with lesions typical for pigeon pox virus infection [ 7 ]. MRSA were present in the air in pigeons exhibitions in Denmark in January 2020 [ 50 ]. It is interesting to note that the prevalence of methicillin resistance is greater among staphylococci from dogs and cats, and this observation probably partly relies on the frequent antibiotic administration and the close contact dogs and cats with humans.…”

Staphylococci are a natural component of the skin microbiota of many organisms, including humans and birds. As opportunistic pathogens, they can cause a variety of infections in humans. The close contact between domestic pigeons and their owners provide an opportunity for exchange of skin-associated bacteria. In this study, 41 healthy racing pigeons were tested. Staphylococci were detected on the skin of each bird (41/41, 100%). Isolates were identified at the species level using matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS). The diversity of the Staphylococcus species was relatively high and coagulase-negative staphylococci (CoNS) were predominantly isolated. In total, ten different staphylococcal species were identified. S. lentus (19/41, 46.3%) was noted most frequently. The pigeon skin was also inhabited by S. xylosus (6/41, 14.6%), S. equorum (4/41, 9.8%), S. hyicus (3/41, 7.3%), S. intermedius (2/41, 4.9%), S. sciuri (2/41, 4.9%), S. vitulinus (2/41, 4.9%), S. lugdunensis (1/41, 2.4%), S. hominis (1/41, 2.4%), and S. auricularis (1/41, 2.4%). Our results indicate that domestic pigeons may carry pathogens with zoonotic potential. All strains were susceptible to 12 antibiotics (ciprofloxacin, clindamycin chloramphenicol, erythromycin, fosfomycin, gentamicin, levofloxacin, norfloxacin, rifampicin, tobramycin, trimethoprim/sulfamethoxazole, vancomycin) representing 8 different classes. None isolate displayed a multidrug-resistant phenotype. Resistance to tetracycline (6/41, 14.6%) and to penicillin (4/41, 9.7%) was shown. The mecA gene was not detected in the examined strains and no methicillin-resistant staphylococci were found on the skin of the healthy pigeons.

“…When it comes to filamentous fungi, the most common descriptions are in broilers (Sugiharto 2019, Hamza & Gunyar 2022 in domestic birds, such as pigeons (Madsen et al 2023), and captive birds (Talbot et al 2018). However, in free-living birds, this interaction remains poorly studied.…”

In Brazil, the Atlantic Forest has been suffering from deforestation, which has had impacts on its flora, fauna, and microbiota. However, the fungal diversity present in these environments is little known and studied. In this study, a total of 90 samples of 45 wild birds (45 feathers and 45 feces) were collected in Ilha da Marambaia, southeastern Brazil. Filamentous fungi isolated from these samples were identified through macroscopic and microscopic characteristics. Some isolates were identified by molecular biology using the PCR technique. Acremonium, Alternaria, Aspergillus, Cunninghamella, Curvularia, Eurotium, Fusarium, Geotrichum, Neosartorya, Pestalotia, Paecilomyces, Penicillium, Rhizopus, Mucor and Syncephalastrum were identified. These results indicate the presence of saprophytic fungi species in the feathers and feces of wild birds of the capture site. Further studies should be conducted to elucidate if the mycobiota profile modifies with anthropization and if it interferes with bird health and environmental recovery.
