Background: The aim of this study was to assess associations of Citrobacter freundii foodborne outbreaks with environmental factors in various regions of Yazd Province, Iran, 2012–2016. Methods: The public health surveillance data were used for one period of five years reported foodborne disease outbreaks in various regions of the Province. Multilevel regression statistical method was used to analyze associations of climatic and demographic variables with outbreaks. Significant associations were tested using likelihood ratio tests. Results: Results showed a significant association between C. freundii outbreaks and air dust conditions, age groups and various regional cities. Conclusion: The current study revealed necessity of etiologic agent identification for use in foodborne disease outbreak guidance in future outbreaks. Systemic surveillance schemes can help prevent and control similar scenarios using reports of environmental effects on foodborne disease outbreaks.

“…1 Nevertheless, with the general increase of antimicrobial resistance, it has been reported that multiresistant C. freundii has been responsible for severe infections in neonates and in immunocompromised patients with therapeutic impasses. 23,24 In our study, we report the detection in the hospital environment of a multiresistant C. freundii coharboring two MBL genes: bla NDM-1 and bla VIM-48 . To the best of our knowledge, this is the first report in Tunisia of the coexistence of two MBL genes in C. freundii.…”

Citrobacter freundii has acquired resistance to several antimicrobial drugs, including last-resort antibiotics affecting, therefore, clinical efficacy and causing high rates of mortality. In this study, we investigate the whole genome sequence of a carbapenem-resistant C. freundii strain isolated from the hospital environment in Tunisia. A total of 210 samples were taken using sterile swabs, from inanimate surfaces, medical devices, and care staff, during the period extended between March and April 2019. After the microbiological analysis of samples and antimicrobial susceptibility testing, only one strain identified as C. freundii showing resistance to carbapenems was selected for the whole genome sequencing. The genome analysis revealed a high-level resistance to most antibiotics. Interestingly, we have noted the coexistence of bla NDM-1 and bla VIM-48 metallo-b-lactamase (MBL) encoding genes conferring resistance to carbapenems. Other b-lactamases encoding genes have also been detected, including bla TEM-1 , bla CMY-48 , and bla OXA-1 . Moreover, genes conferring resistance to aminoglycoside [aac(3)-IId, ant(3 †)-Ia, aadA, aac(6¢)-Ib], macrolide [mph(A)], sulfonamide (sul1), trimethoprim (dfrA1), tetracycline [tet(D)], chloramphenicol [cat(B3)], rifamycin (arr-3), and quinolone (qnrB) have been revealed. The multi-locus sequence typing analysis showed that this isolate could not be assigned to an existing sequence type (ST), but it is almost identical to ST22. The plasmid investigation revealed the presence of five plasmids belonging to diverse incompatibility groups (IncFII, IncHI1A, IncHI1B, IncN, and IncX3). To the best of our knowledge, our findings report the first detection of NDM-1 and VIM-48 coproducing C. freundii in Tunisia and the second detection in the world of the bla VIM-48 .
