“…In this study, 17 bacteria of the Citrobacter freundii species were isolated, accounting for 53.125% of the total isolates. This finding aligns with a study conducted in Europe [12], as well as studies in Egypt [13] and Portugal [14]. However, it differs from the results of studies conducted in Italy [15] and South America [16], where the prevalence of these bacteria was lower.…”

This study aimed to isolate, identify enteric bacterial species from the migratory seagulls migrated to Libyan cost and to assess the antibiotic resistance of these bacteria. A total of 50 fecal samples were collected from slender-billed gulls in January, 2023 at Farwa Island near the city of Zwara. Bacteria were isolated by conventional culturing method, identified by using the Enterosystem 18R, and antibiotic susceptibility testing was conducted on the isolated bacteria. Only 32 of 46 bacteria were identified using biochemical tests. These identified bacteria belong to six species of Enterobacteriacae namely Citrobacter freundii, Pantoea agglomerans, E. coli, Enterobacter cloacae, Serratia liquifaciens, and Proteus mirabilis, with percentages of (17) 53.125%, (10) 31.25%, (2) 6.25%, (1) 3.125%, (1) 3.125%, and (1) 3.125%, respectively. All isolated bacterial species in this study were 100% sensitive to gentamicin and ciprofloxacin. The highest resistance rate was observed against the antibiotic cefoxitin. The results indicated that C. freundii was the most antibiotic-resistant bacterial species isolated in this study. In conclusion, slender-billed gulls carry multi-drug resistant bacteria. The study recommends implementation of a national program to survey antibiotic-resistant bacteria and expanding scientific research on migratory birds.

“…Several studies have pointed out the carriage of AMR pathogens, including salmonellae in wildlife, citing anthropogenic reasons (La Tela et al., 2021; Torres et al., 2020; Vittecoqu et al., 2023). Notably, our findings of Salmonella AST in wildlife mirror those of Bondo et al.…”

AimThis study aimed to summarize the frequency and the antimicrobial susceptibility profiles of the Salmonella serotypes identified from the specimens of companion animals, livestock, avian, wildlife and exotic species within Atlantic Canada.Materials and MethodsThe retrospective electronic laboratory data of microbiological analyses of a selected subset of samples from 03 January 2012 to 29 December 2021 submitted from various animal species were retrieved. The frequency of Salmonella serotypes identified, and their antimicrobial susceptibility results obtained using the disk diffusion or broth method were analysed. The test results were interpreted according to the Clinical and Laboratory Standards Institute standard. The Salmonella serotypes were identified by slide agglutination (Kauffman–White‐Le‐Minor Scheme) and/or the Whole Genome Sequencing for the Salmonella in silico Serovar Typing Resource–based identification.ResultsOf the cases included in this study, 4.6% (n = 154) had at least one Salmonella isolate, corresponding to 55 different serovars. Salmonella isolation was highest from exotic animal species (n = 40, 1.20%), followed by porcine (n = 26, 0.78%), and canine (n = 23, 0.69%). Salmonella subsp. enterica serovar Typhimurium was predominant among exotic mammals, porcine and caprine samples, whereas S. Enteritidis was mostly identified in bovine and canine samples. S. Typhimurium of porcine origin was frequently resistant (>70.0%) to ampicillin. In contrast, S. Typhimurium isolates from porcine and caprine samples were susceptible (>70.0%) to florfenicol. S. Oranienburg from equine samples was susceptible to chloramphenicol, but frequently resistant (>90.0%) to azithromycin. In avian samples, S. Copenhagen was susceptible (>90.0%) to florfenicol, whereas Muenchen was frequently resistant (>90.0%) to florfenicol. S. subsp. diarizonae serovar IIIb:61:k:1,5 of ovine origin was resistant (50.0% isolates) to sulfadimethoxine. No significant changes were observed in the antibiotic resistance profiles across the study years.ConclusionsThis report provides data for surveillance studies, distribution of Salmonella serotypes and their antimicrobial resistance among veterinary specimens of Atlantic Canada.

“…Antimicrobial resistance was generally lower in 2023. Gulls, as sentinels for antimicrobial resistance and carriers of Salmonella spp., may offer valuable insights into the environmental impact of measures addressing AMR in human and veterinary medicine [ 33 , 34 , 35 ]. Regulations aiming to control this serious public health problem have been in place since 2006, when the European Union prohibited the use of antibiotics as growth promoters [ 36 ].…”

Gulls act as intermediaries in the exchange of microorganisms between the environment and human settlements, including Salmonella spp. This study assessed the antimicrobial resistance and molecular profiles of Salmonella spp. isolates obtained from fecal samples of gulls in the city of Porto, Portugal, in 2008 and 2023 and from water samples in 2023. Antimicrobial susceptibility profiling revealed an improvement in the prevalence (71% to 17%) and antimicrobial resistance between the two collection dates. Two isolate collections from both 2008 and 2023 underwent serotyping and whole-genome sequencing, revealing genotypic changes, including an increased frequency in the monophasic variant of S. Typhimurium. qacE was identified in 2008 and 2023 in both water and fecal samples, with most isolates exhibiting an MDR profile. The most frequently observed plasmid types were IncF in 2008 (23%), while IncQ1 predominated in 2023 (43%). Findings suggest that Salmonella spp. circulate between humans, animals, and the environment. However, the genetic heterogeneity among the isolates from the gulls’ feces and the surface water may indicate a complex ecological and evolutionary dynamic shaped by changing conditions. The observed improvements are likely due to measures to reduce biological contamination and antimicrobial resistance. Nevertheless, additional strategies must be implemented to reduce the public health risk modeled by the dissemination of pathogens by gulls.
