A Rare Case ofRaoultella planticolaUrinary Tract Infection in a Patient With Immunoglobulin A Nephropathy

Abstract

Raoultella planticola is a gram-negative, aerobic, nonmotile mostly found in environments with high prevalence in soil and water. This organism is a very rare human pathogen as only 29 cases of Raoultella planticola–related infections have been reported until 2017, with only 7 cases in the United States. Only 3 cases of urinary tract infection secondary to R planticola have been reported, 1 in a pediatric patient and 2 in adults. In this article, we present a case of R planticola urinary tract infection in a 65-year-old male with immunoglobulin A nephropathy. On investigation, the patient was found to be septic and empirical antibiotic was started for gram-negative coverage. The patient showed remarkable improvement and discharged on oral antibiotic for 7 days. R planticola rarely cause infection in humans, with overall good prognosis.

A rare case of Raoultella planticola urinary tract infection. A case report with literature review

“…Urine culture showed the presence of R. planticola bacteria, which were sensitive to all major antibiotics, including ceftriaxone, ciprofloxacin, nitrofurantoin, cefazolin, gentamicin and trimetoprim-sulfamethoxazole. As a result of antibiotic therapy, the patient was cured without complications [16].…”

Case Report and Review of Raoultella Planticola Urinary Tract Infection

“…Other cases include reports of pneumonia, wound infection, cholangitis, bacteremia and conjunctivitis (Serkan et al, 2018). In this case, we present a patient with a confirmed case of Raoultella planticola urinary tract infection (Mehmood et al, 2018;Serkan et al, 2018).…”

“…It is a histamine-producing bacterium generally found in aquatic environments, in fish and in soil (Lam and Salit, 2017). It is not generally thought to be pathogenic, but recent cases of human infection are emerging, most commonly in fragile, frequently hospitalized patients with multiple comorbidities and in the pediatric population (Kalaria et al, 2017;Mehmood et al, 2018;Serkan et al, 2018;Skelton et al, 2017;Xu et al, 2016). There is one concerning case report of carbapenem resistance with R. planticola infection (Skelton et al, 2017).…”

“…planticola is closely related to Klebsiella and was originally classified as Klebsiella trevisanii after its discovery in 1984 and reclassified in 2001. (Mehmood et al, 2018) There have been 31 documented case reports of Raoultella planticola, four of which were cases of urinary tract infection. Other cases include reports of pneumonia, wound infection, cholangitis, bacteremia and conjunctivitis (Serkan et al, 2018).…”

Recurrent urinary tract infections caused by Raoultella planticola after kidney transplant

“…One retrospective study found that 56% of the patients with a UTI due to R planticola were immunodeficient; 28% of these being solid organ transplant recipients . Additionally, most case reports describe R planticola as pan‐sensitive to most antimicrobial options including penicillins and cephalosporins, with the reports of resistance describing non‐susceptibility to ampicillin and piperacillin . These case reports of UTI due to R planticola describe successful treatment with agents such as ceftriaxone, ciprofloxacin, cephalexin, and ampicillin/sulbactam.…”
