Abstract: Chryseobacterium, are a group of aerobic, nonfermentative, nonmotile, catalase positive ,oxidase positive and indole positive Gram-negative bacilli, utilizes glucose oxidatively and does not grow on MacConkey agar. The organism produces a non diffusible yellow pigment (flexirubin) and, hence, was earlier called Flavobacterium indologenes. They are rare human pathogen, but widely distributed in soil, plants, food and potable water. It can cause serious infection in immunocompromised patients, but it has been increasingly isolated from patients with bacteraemia, pneumonia and long term intravascular devices such as venous catheters, intravascular implants, urinary catheters, intubation and mechanical ventilation devices. Despite their low virulence, Chryseobacteria are inherently resistant to many antimicrobial agents including Imipenem. We reported a case of pneumonia with septicaemia caused by C.Indologenes in postoperative patient of carcinoma stomach with indwelling internal jugular vein catheter.
