Bacteremia due to Cupriavidus pauculus (formerly CDC Group IVc-2) in a hemodialysis patient

A case of newborn with community acquired pneumonia caused by Cupriavidus pauculus

“…It may occur as an opportunistic pathogen both in the hospital and in the environment, causing to outbreaks especially in the intensive care units. Hydrotherapy pools, nebulization solutions, tap water, and even bottled mineral water have been recognized as potential sources of contamination (1,2). Although there have been many case reports of airway infection, blood stream infection, peritonitis, abscess, and tenosynovitis in adults, a few cases have been reported in children (1)(2)(3)(4)(5).…”

Cupriavius pauculus causing a respiratory tract infection in a post-kidney-transplant patient: A firstly described rare clinical case

“…In this particular case, medical devices such as hemodialysis circuit equipment and the patient's ventilator (sources previously reported in literature) could represent the origin of contamination. 6,12 However, all equipment samples collected did not grow any organism in this case, suggesting that no environmental contamination was involved. Concerning the treatment approach, isolation of C. pauculus from a clinical specimen is generally treated with high index of suspicion and usually regarded as contamination unless proven otherwise.…”

“…1 Widely distributed in nature, specially in water and soil, isolation has occurred in environmental samples of pool water, groundwater, tap and bottled mineral water when suspected to be a potential source of contamination in the clinical setting. [2][3][4][5][6][7][8] The genus Cupriavidus contains 13 species, being C. pauculus historically implicated in the majority of the, nevertheless rare, infections. Both immunocompromised patients (with underlying comorbidities such as Chronic Kidney Disease (CKD), hematologic malignancies and Acquired Immunodeficiency Syndrome) and immunocompetent patients have been reported with infection, either in community or nosocomial setting.…”

Implantable Cardiac Defibrillator Pocket Infection Due to a Previously Undescribed Cupriavidus Species

“…The bacteria have also been isolated from pool water, ground water, and bottled mineral water (14). C. respiraculi, C. pauculus, C. gilardii, C. metallidurans, C. basilensis, and a novel Cupriavidus species have been found in clinical isolates from cystic fibrosis patients (5,6,16). C. gilardii has also been described in a fatal disseminated infection in a child with aplastic anemia (7).…”

“…A 29-year-old woman with congenital heart disease and a left-sided implantable cardiac defibrillator (ICD) placed on 16 September 2008 for complete heart block underwent a lead revision due to atrial lead dislodgement on 17 February 2009. She subsequently developed pain, erythema, and swelling at the pocket site and was admitted on March 22.…”
