“…First, differences in dietary practices play a significant role, as food can act as a carrier of antibiotic‐resistant bacteria, making it crucial to analyse the potential impact of diet on resistance patterns (Barragán‐Fonseca et al., 2022 ; Tubón et al., 2022 ). Second, the diverse origins of the zoo animals, which come from various places with different veterinary practices and histories of human and animal contact, make it challenging to trace the sources of resistant bacteria they may carry (Furlan et al., 2024 ). Third, vectors such as flies and birds, as well as zoo personnel, could contribute to the transmission of antibiotic‐resistant bacteria within the zoo (Yin et al., 2022 ).…”

BackgroundThis study focuses on the AMR profiles in E. coli isolated from captive mammals at EcoZoo San Martín, Baños de Agua Santa, Ecuador, highlighting the role of wildlife as reservoirs of resistant bacteria.AimsThe aim of this research is to investigate the antimicrobial resistance profiles of E. coli strains isolated from various species of captive mammals, emphasizing the potential zoonotic risks and the necessity for integrated AMR management strategies.Materials & MethodsA total of 189 fecal samples were collected from 70 mammals across 27 species. These samples were screened for E. coli, resulting in 90 identified strains. The resistance profiles of these strains to 16 antibiotics, including 10 β‐lactams and 6 non‐β‐lactams, were determined using the disk diffusion method. Additionally, the presence of Extended‐Spectrum Beta‐Lactamase (ESBL) genes and other resistance genes was analyzed using PCR.ResultsSignificant resistance was observed, with 52.22% of isolates resistant to ampicillin, 42.22% to ceftriaxone and cefuroxime, and 27.78% identified as ESBL‐producing E. coli. Multiresistance (resistance to more than three antibiotic groups) was found in 35.56% of isolates. Carnivorous and omnivorous animals, particularly those with prior antibiotic treatments, were more likely to harbor resistant strains.DiscussionThese findings underscore the role of captive mammals as indicators of environmental AMR. The high prevalence of resistant E. coli in these animals suggests that zoos could be significant reservoirs for the spread of antibiotic‐resistant bacteria. The results align with other studies showing that diet and antibiotic treatment history influence resistance profiles.ConclusionThe study highlights the need for an integrated approach involving veterinary care, habitat management, and public awareness to prevent captive wildlife from becoming reservoirs of antibiotic‐resistant bacteria. Improved waste management practices and responsible antibiotic use are crucial to mitigate the risks of AMR in zoo environments and reduce zoonotic threats.

“…Here, they demonstrate that environmental variations and host sex can influence the structure of interaction networks formed between bats and their ectoparasitic flies. Furlan et al (2024) investigated and characterized multidrug-resistant (MDR) gram-negative bacterial strains infecting or colonizing mammals, reptiles, amphibians, and birds from the largest zoo in Latin America. They identified different bacterial species, but only Escherichia coli and Klebsiella pneumoniae presented MDR profiles.…”

The International Society of Zoological Sciences has developed a Wildlife Diseases Research Network (WDRN) in the world, with the collaboration of its partners such as the Working Group on Zoonotic Disease of the International Union of Biological Sciences (IUBS) (https://iubs.org/). WDRN is composed of a steering committee, a scientific committee, a research expert network, and collaborative partners. WDRN will hold annual symposia, workshops, and training courses and publish an annual report on wildlife diseases. With support from the WDRN's expert teams and its partners, WDRN aims to build a database and information center to facilitate the research, monitoring, prevention, and control of wildlife diseases around the world. WDRN is devoted to working with IUBS, WHO, WOAH (OIE), FAO, and other organizations to promote the prevention and control of zoonotic diseases in the world.In 2023, WDRN held two symposiums. The 1st WDRN symposium was held in Haikou, Hainan province, China from the 26th to 28th of June 2023. It consisted of 8 plenary reports, 12 thematic seminars and 3 thematic discussions. During the meeting, participants had a lively discussion and provided valuable suggestions for the construction of a comprehensive health research and international wildlife disease research network. The 2nd WDRN symposium was held in Beijing, China, on December 5-7, 2023. There were 29 oral presentations and 3 thematic discussions in this meeting. More than 100 people from 14 countries attended this symposium.
