In Brazil, the Atlantic Forest has suffered from deforestation, which has caused impacts on its flora, fauna, and microbiota. This biome is considered one of the main tourist and birdwatching destinations due to the large number of species, especially Passeriformes. However, the fungal diversity present in these environments is little known and studied. In this work, a total of 148 samples from 74 wild birds (74 feathers and 74 feces) and 16 samples of litter were collected in Itatiaia National Park, southeastern Brazil. Filamentous fungi isolated from these samples were identified using macroscopic and microscopic characteristics. Among birds, Aspergillus spp., Mucor spp., Cladosporium spp., Fusarium spp., Penicillium spp. and Syncephalastrum spp. were identified in higher abundance. In litter, Aspergillus spp., Fusarium spp. and Penicillium spp. were identified. These results indicate the presence of saprophytic fungi species in the feathers and feces of wild birds and in the litter of the capture site. Further studies should be conducted in order to elucidate if the mycobiota profile modifies with anthropization and if it interferes with bird health and environmental recovery.

“…A total of 66 freshly dropped wet fecal samples from migratory birds were collected from the ground and tree leaves. Based on the procedure of Akter et al [ 55 ], samples were collected using sterilized cotton buds and were transferred to separate sterilized zip lock bags with particular tag numbers followed by transferring to the laboratory while maintaining cold chain throughout. Each sample was added to 5 mL nutrient broth (HiMedia, India) in a sterilized test tube.…”

Migratory birds are carriers of multidrug resistant pathogenic Escherichia coli. However, their roles in the dissemination of these resistant pathogens are still being neglected in Bangladesh. The present study was therefore carried out to detect multidrug resistant E. coli. In addition, these isolates were also screened for the presence of avian pathogenic E. coli (APEC)-associated virulence genes. A total of 66 fecal matter samples of migratory birds were screened. E. coli were isolated and identified by culturing and biochemical tests followed by polymerase chain reaction (PCR). APEC-associated virulence genes were detected by PCR. Disk diffusion assays were employed to investigate antibiogram profiles. Bivariate analysis was performed to assess correlations in resistance patterns between antimicrobials and to assess associations between virulence genes of E. coli. Among the 66 samples assessed by PCR, 55 (83.33%) were found positive for E. coli. Of these 55 isolates, the APEC-associated virulence gene fimC was detected in 67.27% of the isolates, which was significantly higher than in the cases of iucD (29.09%) and papC (5.45%) genes. In addition, three isolates were found positive for all three virulence genes, while 23 and 12 isolates were positive for one and two virulence genes respectively. In the bivariate analysis, significant associations were detected between fimC and iucD virulence genes. Using the antibiogram, all E. coli isolates were found to be multidrug resistant (MDR). The isolates exhibited 100% resistance against ampicillin and erythromycin in addition to varying percentages of resistance against streptomycin, tetracycline, ciprofloxacin, and chloramphenicol. Highly positive correlations between tetracycline and ciprofloxacin, chloramphenicol and ciprofloxacin, chloramphenicol and tetracycline were observed by bivariate analysis. To the best of our knowledge, this is the first study that reports APEC-associated virulence genes of MDR E. coli from migratory birds in Bangladesh. Results indicate that migratory birds are reservoirs of MDR E. coli isolates carrying APEC-associated virulence genes, which can seriously contribute to the development of human and animal diseases.

“…A total of 66 fecal materials of migratory birds were collected from Baojani Baor, Mohammadpur Upazila (23.4056° N, 89.5686° E) in Magura district of Bangladesh during November 2019 and November 2020. The samples were collected by following the previously described procedure ( Akter et al, 2020 ). In brief, each sample, collected by whirling a sterilized cotton bud into migratory bird’s dropping, was shifted to a separate sterilized zip lock bag with a particular tag number and directly transferred to the laboratory maintaining a cool chain.…”

Antimicrobial resistance (AMR) is a major health crisis globally. Migratory birds could be a potential source for antibiotic resistant (ABR) bacteria. Not much is known about their role in the transmission of ABR in Bangladesh. In this study, a total of 66 freshly dropped fecal materials of migratory birds were analyzed. Bacterial isolation and identification were based on cultural properties, biochemical tests, and polymerase chain reaction (PCR). The disk diffusion method was employed to evaluate antibiogram profiles. By PCR, out of 66 samples, the detection rate of Enterococcus spp. (60.61%; 95% confidence interval: 48.55–71.50%) was found significantly higher than Salmonella spp. (21.21%; 95% CI: 13.08–32.51%) and Vibrio spp. (39.40%; 95% CI: 28.50–51.45%). Enterococcus isolates were frequently found resistant (100–40%) to ampicillin, streptomycin, meropenem, erythromycin, and gentamicin; Salmonella isolates were frequently resistant (72–43%) to chloramphenicol, tetracycline, ampicillin, streptomycin, and erythromycin; and Vibrio spp. isolates were frequently resistant (77–31%) to vancomycin, ampicillin, erythromycin, tetracycline, and streptomycin. In addition, 60% (95% CI: 44.60–73.65%) Enterococcus spp., 85.71% (95% CI: 60.06–97.46%) Salmonella spp., and 76.92% (95% CI: 57.95–88.97%) Vibrio spp. isolates were multi-drug resistant (MDR) in nature. Three isolates (one from each bacterium) were found resistant against six classes of antibiotics. The bivariate analysis revealed strong associations (both positive and negative) between several antibiotic pairs which were resistant to isolated organisms. To the best of our knowledge, this is the first study in detecting MDR Enterococcus spp., Salmonella spp., and Vibrio spp. from migratory birds travelling to Bangladesh. Frequent detection of MDR bacteria from migratory birds travelling to Bangladesh suggests that these birds have the potential to carry and spread ABR bacteria and could implicate potential risks to public health. We recommend that these birds should be kept under an AMR surveillance program to minimize the potential risk of contamination of the environment with ABR as well as to reduce their hazardous impacts on health.
