Abstract
Background: Birds harbor Enterococcus faecium and Enterococcus faecalis as gut commensals but could acquire and transmit high-priority strains.
Methods: Following the PRISMA guidelines, eligible studies that reported the antimicrobial resistance (AMR) profiles of E. faecium and E. faecalis from gut samples of food-producing (FPBs) and wild birds (WBs) published from 2005 to 2024 were screened from major bibliographic databases. Random-effect models were used to determine the pooled prevalences (PPs) of vancomycin (VANR), ampicillin (AMPR), and linezolid (LZDR) resistant E. faecium and E. faecalis from non-duplicated gut samples of food-producing (FPBs) and wild birds (WBs).
Results: Of the 36 eligible studies, the overall PP of VANR-E. faecium and VANR-E. faecalis were 1.8% and 0.7%, respectively. AMPR-E. faecium and AMPR-E. faecalis were 1.6% and 0.6%, respectively. LZDR-E. faecium and LZDR-E. faecalis were 1% and 0.8%, respectively. Subgroup analyses revealed significant temporal variations in the PPs of VANR-E. faecium (p < 0.05). FPBs had significantly higher PPs of VANR, AMPR and LZDRE. faecium and E. faecalis than WBs (p < 0.05). Healthcare-associated vanA-carrying E. faecium lineages from WBs (ST16, ST17, ST18, and ST412) and optrA-carrying E. faecalis lineages (ST32, ST59, ST330) from FPBs were identified. In FPBs, Egypt had the highest PP of VANR-E. faecium (11.9%) and LZDR-E. faecalis (2.8%). Conversely, the USA had the highest PP of VANR-E. faecium in WBs (2.4%).
Conclusions: A higher frequency of vancomycin- than linezolid-resistant strains exists, and VANR-E. faecium are disproportionately distributed based on bird species, years of study, and countries, indicating varied selection pressure. Significantly higher prevalence of VANR-E. faecium than VANR-E. faecalis was found, highlighting the higher capacity of E. faecium to acquire ampicillin and vancomycin resistance in birds.
期刊介绍:
Avian Pathology is the official journal of the World Veterinary Poultry Association and, since its first publication in 1972, has been a leading international journal for poultry disease scientists. It publishes material relevant to the entire field of infectious and non-infectious diseases of poultry and other birds. Accepted manuscripts will contribute novel data of interest to an international readership and will add significantly to knowledge and understanding of diseases, old or new. Subject areas include pathology, diagnosis, detection and characterisation of pathogens, infections of possible zoonotic importance, epidemiology, innate and immune responses, vaccines, gene sequences, genetics in relation to disease and physiological and biochemical changes in response to disease. First and subsequent reports of well-recognized diseases within a country are not acceptable unless they also include substantial new information about the disease or pathogen. Manuscripts on wild or pet birds should describe disease or pathogens in a significant number of birds, recognizing/suggesting serious potential impact on that species or that the disease or pathogen is of demonstrable relevance to poultry. Manuscripts on food-borne microorganisms acquired during or after processing, and those that catalogue the occurrence or properties of microorganisms, are unlikely to be considered for publication in the absence of data linking them to avian disease.
