    Abstract Mycoremediation uses mushroom forming fungi for remediation of sites contaminated with biotic and abiotic contaminants. The root-like hyphae of many fungi, the mycelia, have been used to remediate soil and water. In this study mushroom mycelia biofilters were evaluated for remediation efficacy of wetland water polluted with crow feces containing antibiotic resistant (AMR) bacteria. Three strains of fungi,

    Abstract AIM: The study examined the hypothesis that crow‐borne Campylobacter can function as environmental reservoirs and indicators of antibiotic resistance (AR) determinants circulating in a human population. METHODS AND RESULTS: Two species of crows from Washington (WA), United States, and Kolkata, India, respectively, were examined for their ability to carry antibiotic resistant Campylobacter. Campylobacter jejuni was the only species isolated by selective agar plating from crow faecal samples. Disk diffusion method used to compare the AR profile of the isolates showed tetracycline (TET) resistance to be the most prevalent (27%) among WA isolates, followed by ciprofloxacin (CIP; 24%). Among Kolkata isolates, nalidixic acid resistance was most common (36%), followed by CIP (27%). The AR profile demonstrated by crow isolates of WA reflects those reported by the US National Antimicrobial Resistance Monitoring System for human isolates (2007–2011), where resistance to TET was most prevalent (≈45%), followed by quinolones (≈24%). The Kolkata crow isolates reflected the AR profile of human clinical isolates from India, where 97% resistance was shown to quinolones, followed by TET (18%). Multilocus sequence typing of 37 isolates, including 11 water isolates from the crow roost area, showed 24 different sequence types (STs). Seventeen of these were previously found in wild birds, 2 in human diarrhoea, 4 in poultry and 8 in environmental water. One isolate was found in both water and faeces, though from different sites within WA. CONCLUSIONS: The results indicate that crows most likely acquire the AR from anthropogenic sources. Although they are colonized by specific STs, rarely isolated from humans, they can facilitate the spread of AR. SIGNIFICANCE AND IMPACT OF THE STUDY: By studying two areas in different continents, this research demonstrates that Campylobacter borne by crows can function as environmental reservoirs and indicators of AR determinants that circulate in a human population. This information will be of importance to scientists from the medical and poultry industries.

    Abstract The study examines whether crows are carriers of extraintestinal pathogenic E. coli (ExPEC) and avian pathogenic E. coli (APEC)-like strains, and if wetland roost areas contribute to their spread. A total of 10 crow feces (n = 71) and 15 water E. coli isolates (n = 134) from a wetland area could be characterized as potentially ExPEC based on the presence of ≥2 of the five cardinal genes iutA, kpsMT2, papEF, pap A/C, papG, sfa/foc, and afa/dra, while six fecal and 14 water isolates could be characterized as potentially APEC-like based on the presence of plasmid associated genes: iutA, episomal iss, ompT, hlyF and iroN. A total of 32 fecal and 27 water isolates tested carried plasmids based on incompatibility typing. Plasmids from 34 of 38 isolates tested could be transferred to another E. coli strain by conjugation with the antibiotic resistance (AR) profile being transferred, indicating their potential to be transferred to indigenous and non-pathogenic strains in the wetland. APEC-like plasmids could be transferred in six of eight isolates tested. Pathogenic E. coli of importance to the medical community and poultry industry may be detected in high levels in surface water due to corvid activity. Regardless of their role in health or disease, water in wetlands and streams can serve as a media for the dissemination of AR and virulence traits of bacteria, with corvids acting as potential vectors for farther dissemination.
