Early and massive tissue necrosis is a specific feature of C. koseri brain infection. The early stage of the disease predominates in the white matter, causing cerebritis; the later stage is marked with necrotic cavities in multiple locations. The cavities are initially square in shape and not tense, but when pus forms and collects in these cavities, they tend to become more rounded in shape; a persisting cavity leads to septated ventriculitis that may result in multicyctic hydrocephalus.

WebThe 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) Citrobacter diversus (composed of H 2 S-negative, indole-positive, and adonitol-positive cultures). WebCitrobacter can cause septicemia in patients that display a number of predisposing factors. Citrobacter have also been found to cause meningitis, septicemia, and pulmonary infections in neonates and young children, and some of these cases have been linked to contaminated batches of PIF.
