Polymicrobial Peritonitis Including Pantoea Agglomerans From Teething on a Catheter

Pantoea agglomerans: A rare infectious outbreak affecting maintenance hemodialysis patients in a tertiary care hospital

BACKGROUND

Pantoea agglomerans is an environmental pathogen known to cause infection in immunocompromised individuals, particularly after thorn injuries. However, previous data showed few cases of human disease caused by contaminated medical products such as parenteral nutrition, anesthetic agents, blood, and peritoneal dialysis solutions. Infection in hemodialysis patients is rare. In this study, we presented a detailed account of several hemodialysis patients infected with this contagious pathogen and compared them with noninfected dialysis patients.

METHODS

We retrospectively reviewed the hospital records of 105 hemodialysis patients. Seventeen of 105 patients were diagnosed with P. agglomerans infection. We carefully analyzed their entire in-hospital course.

RESULTS

Among infected patients, 52.9% were male with a median age of 49 (IQR: 32-66) years. Compared to the noninfected patients, age below 50 years, prior kidney transplantation, prior immunosuppression and antibiotics use, and dialysis via a tunneled vascular catheter were the significant epidemiological features. Despite negative microbiological investigations, we suspect the possible infectious spread via infected central venous catheter was the likely infectious source. Most importantly, all patients responded well to intravenous antibiotics. Only two patients required the removal of the tunneled catheter. Their mortality rate was 0%.

CONCLUSION

P. agglomerans infection, although considered rare, is becoming increasingly prevalent among dialysis patients. Its occurrence must be appraised as an infectious outbreak rather than mere contamination. Prompt treatment, source identification, and early implementation of preventive strategies should always be the goal to curtail this infection at an early stage.

Pantoea abscess mimicking sarcoma in a HTLV-1-infected Indigenous Australian man: Case report and literature review

Gram-negative bacteria of the genus Pantoea are emerging bacterial causes of diverse sporadic and outbreak-linked infections. Chronic Pantoea abscesses are unusual and may give rise to a differential diagnosis of malignancy. Foreign body retention and host immune defects may be risk factors for such chronic infections.

Pantoea in Peritoneal Dialysis: A Rare Cause of Peritonitis

Peritonitis is the most common complication of peritoneal dialysis (PD) and an important cause of PD failure. There are numerous etiological agents, mostly bacteria. Pantoea spp is a rare cause of peritonitis.

We describe three cases of Pantoea peritonitis in three PD patients. Previous reports have identified risk factors such as close contact with plants and animals. We review the typical clinical presentation and prognosis. It is fulcral to teach patients about the risks regarding proximity to plants and animals to prevent this type of infection.

Unusual causes of peritonitis in a peritoneal dialysis patient: Alcaligenes faecalis and Pantoea agglomerans

An 87 -year-old female who was undergoing peritoneal dialysis presented with peritonitis caused by Alcaligenes faecalis and Pantoea agglomerans in consecutive years. With the following report we discuss the importance of these unusual microorganisms in peritoneal dialysis patients.

Pantoea agglomerans, a plant pathogen causing human disease

We present 53 pediatric cases of Pantoea agglomerans infections cultured from normally sterile sites in patients seen at a children's hospital over 6 years. Isolates included 23 from the bloodstream, 14 from abscesses, 10 from joints/bones, 4 from the urinary tract, and 1 each from the peritoneum and the thorax. P. agglomerans was most associated with penetrating trauma by vegetative material and catheter-related bacteremia.
