    Detection of antimicrobial-resistant Enterobacterales in insectivorous bats from Chile
    (Royal Society Publishing, 0023-11) Rojas-Sereno, Zulma Esperanza; Streicker, Daniel G; Suarez-Yana, Tania; Lineros, Michelle; Yung, Verónica; Godreuil, Sylvain; Benavides, Julio A
    Enterobacterales of clinical importance for humans and domestic animals are now commonly detected among wildlife worldwide. However, few studies have investigated their prevalence among bats, particularly in bat species living near humans. In this study, we assessed the occurrence of Extended-spectrum beta-lactamase-producing (ESBL) and carbapenemase-resistant (CR) Enterobacterales in rectal swabs of bats submitted to the Chilean national rabies surveillance program from 2021 to 2022. From the 307 swabs screened, 47 (15%) harboured cefotaxime-resistant Enterobacterales. Bats carrying these bacteria originated from 9 out of the 14 Chilean regions. Most positive samples were obtained from Tadarida brasiliensis (n = 42), but also Lasiurus varius, L. cinereus and Histiotus macrotus. No Enterobacterales were resistant to imipenem. All ESBL-Enterobacterales were confirmed as Rahnella aquatilis by MALDI-TOF. No other ESBL or CR Enterobacterales were detected. To our knowledge, this is the first screening of antibiotic-resistant bacteria in wild bats of Chile, showing the bat faecal carriage of R. aquatilis naturally resistant to cephalosporins, but also including acquired resistance to important antibiotics for public health such as amoxicillin with clavulanic acid. Our results suggest unknown selective pressures on R. aquatilis, but low or no carriage of ESBL or CR Escherichia coli and Klebsiella spp. Future studies should assess the zoonotic and environmental implications of R. aquatilis, which are likely present in the guano left by bats roosting in human infrastructures. © 2023 The Authors.

    ESBL-producing Escherichia coli prevalence and sharing across seabirds of central Chile
    (Elsevier B.V., 2025-02) Suarez-Yana, Tania; Salgado-Caxito, Marilia; Hayer, Juliette; Rojas-Sereno, Zulma Esperanza; Pino-Hurtado, Mario Sergio; Campaña-Burguet, Allelen; Caparrós, Cristina; Torres, Carmen; Benavides, Julio A.
    The authors regret that in ‘Highlights’, the first two sentences lack of a final dot, the presence/absence of abbreviations and italic text in specific words, and that in Section 3.2.3: a question mark (?) was mistakenly written. Upon reviewing the published article, we found discrepancies in the text of the Abstract, the first and fourth paragraphs in the ‘Discussion’ section, the Graphical abstract, and Fig. 6 where it indicates that the Sequence Type (ST) 617 is shared between the Franklin's gull and Peruvian pelican. The correct finding is that ST617 is shared between the Kelp gull and the Peruvian pelican. It appears that these issues are the result of a typesetting error, which regrettably went unnoticed by the authors during the proofreading phase. However, the authors clarify that these errors do not alter the principal findings, discussion and conclusions of the paper, since in other parts of the text, the information was properly presented. Therefore, the formal changes requested in the text are: • At page 1, in ‘Highlights’ add a final dot in the first two sentences, and replace “ESBL-genes” with “ESBL genes”.• At page 2, in ‘Abstract’ replace “ST10 (Ld and Pt); ST88, ST410 and ST617 (Pt and Lp)” with “ST10 and ST617 (Ld and Pt); ST88 and ST410 (Pt and Lp)”.• At page 5, in Section 3.2.1 change to italic text the word “bla” in “Some of the most prevalent AMR genes in the study included blaEC gene”.• At page 6, in Section 3.2.3 delete question mark in “The ESBL-E. coli ST617 identified in two Kelp gulls in summer 2021 and winter 2022?”, and change to non-italic text the words “CTX-15” and “OXA-1” in “one Peruvian pelican in summer 2021 harboured genes blaCTX-M-15 and blaOXA-1”.• At page 7, in ‘Discussion’ replace “whole genome sequence” with the abbreviation “WGS”, and replace “Peruvian pelicans and Franklin's gulls (ST88, ST410, and ST617), and by Kelp gulls and Peruvian pelicans (ST10)” with “Peruvian pelicans and Franklin's gulls (ST88 and ST410), and by Kelp gulls and Peruvian pelicans (ST10 and ST617)”.• At page 10, in ‘Discussion’ add the characters “l” to the word “wordwide” in “blaCMY-2, the most prevalent plasmid mediated AmpC gene wordwide” and “s” to the abbreviation “ST” in “A high diversity of ST”, and replace “ST410 and ST617 in Peruvian pelicans and Franklin's gulls” with “ST410 and ST617 in Peruvian pelicans, Franklin's gulls (ST410), and Kelp gulls (ST617)”.The corrected versions of the Graphical abstract and Fig. 6 are provided in this corrigendum as Figs. 1 and 2, respectively.
