WebJan 1, 1984 · Publisher Summary. This chapter discusses the biochemical and serological characterization of Citrobacter. The genus Citrobacter consists of Gram-negative peritrichous rods. The genus is subdivided into two species: (1) Citrobacter freundii (includes mostly H 2 S-positive, indole-negative, and adonitol-negative cultures) and (2) … WebDOI: 10.1016/j.jiac.2016.07.003. Among the Citrobacter genus, the most commonly isolated bacteria from human specimens are Citrobacter freundii and Citrobacter koseri, and previous cases of infection due to Citrobacter braakii have been rarely reported. We present a case of bacteremia due to C. braakii in a 38-year-old woman with cervical cancer.
