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.

Gram-negative infections are a rising concern faced by the medical community. Approximately 30% of nosocomial bloodstream infections in intensive care units in the United States are caused by these gram-negative species. Emergence of multidrug-resistant organisms further complicate this issue. In this article, we report a case of an 84-year-old Caucasian male who was diagnosed with Shewanella pneumonia treated with cefepime with minimal to no improvement in his symptoms. To the best of our knowledge, this is the third reported case of Shewanella putrefaciens nosocomial pneumonia and first case of bacteremia secondary to pneumonia by Shewanella putrefaciens.

Complicated nontyphoidal Salmonella infections and its recurrences have been reported infrequently in transplant patients. As such, there is no standard consensus regarding treatment options and prevention of recurrences in this population. We present a renal transplant patient who developed recurrent urinary tract infections with Salmonella enteritidis, complicated by bacteremia and endocarditis, and discuss our management for this challenging case.

In the absence of coexisting immunocompromised state and lack of specific symptoms a reactivation of treated mycobacterial tuberculosis (MTB) infection is generally not considered in the differential diagnosis of leg pain. We present a unique case of disseminated tuberculosis presenting as an infected Baker's cyst in a 73-year-old immunocompetent male.
