Abstract:
Active population-based surveillance determined clinical factors, susceptibility patterns, incidence rates (IR), and genomics among Enterobacter cloacae complex (n = 154) causing blood stream infections in a centralized Canadian region (2015-2017). The annual population IR was 1.2/100,000 (95% CI 0.9-16) in 2015, 1.4/100,000 (95% CI 1.1-1.9) in 2016, and 1.5/100,000 (95% CI 1.2-2.0) in 2017, affecting mainly elderly males with underlying comorbid conditions in the hospital setting. E. cloacae complex was dominated by polyclonal subspecies (i.e., E. hormaechei subsp. steigerwaltii, subsp. hoffmanni and subsp. xiangfangesis). Antimicrobial resistant determinants were rare. This study provided novel information about Enterobacter genomics in a well-defined human population.
