“…Alternative antimicrobial agents were cotrimoxazole, beta lactams, and tetracyclines [ 9 ]. Morganella morganii is usually susceptible to quinolones such as ciprofloxacin, aminoglycosides, such as gentamicin, amikacin, tobramycin, chloramphenicol, cotrimoxazole, aztreonam, and other carbapenems [ 10 ]. Morganella morganii are resistant to penicillins and many cephalosporins through the formation of ESBL and Amp C-beta lactamase production [ 11 ].…”

Case Reports in Transplantation

Bacterial infection is a common complication after Hematopoietic Stem Cell Transplantation (HSCT). Morganella morganii is ubiquitous Gram-negative facultative anaerobe, which may cause many kinds of opportunistic infection. Herein we report a case of a 55-year-old man who presented with frequent urination, urgency, and mild pain that comes and goes low in the abdomen and around the anus. The patient had a medical history of chronic prostatitis for 4 years. He received HLA-matched sibling allo-HSCT because of angioimmunoblastic T-cell lymphoma 29 months ago. The routine examination of prostatic fluid showed increased leukocytes and the culture of prostatic fluid showed Morganella morganii subsp. morganii. The patient developed chills and fever 18 hours after examination. Both urine culture and blood culture showed Morganella morganii subsp. morganii. The patient was successfully treated with antibiotic therapy and septic shock management. Taken together, Morganella morganii should be considered a possible pathogen when immunocompromised patients develop prostatitis. Also, prostatic massage could be a possible trigger of septic shock induced by Morganella morganii subsp. morganii in a posttransplantation patient.

“…Proteus species are non-lactose fermenting, facultatively anaerobic, gram-negative motile rods that belong to the order Enterobacterales and commonly exist as normal inhabitants of the gastrointestinal tract [ 1 ]. These are easily identified by their classic “swarming” appearance on culture media (associated with the conversion of short swimmer cells into highly elongated hyper-flagellated swarmer cells) and distinct “chocolate cake” or “burnt chocolate” smell; the genus has four named species known to cause human clinical infections, such as Proteus mirabilis , Proteus vulgaris , Proteus penneri , and Proteus hauseri [ 1 , 2 ]. P. mirabilis is the most frequently encountered species responsible for 80%-90% of all Proteus infections in man [ 2 ].…”

The presence of Proteus species in the pleural space is an uncommonly reported entity and is rarely seen even in patients with compromised immune status. We report a case of pleural empyema due to Proteus species in an adult oral cancer patient receiving chemotherapy for academic interest and for generating awareness regarding an expanded pathogenic spectrum of the organism. A 44-year-old salesman, nonsmoker and non-alcoholic, presented with sudden-onset shortness of breath, left-sided chest pain, and lowgrade fever of one-day duration. He had been recently diagnosed with adenocarcinoma of the tongue and had received two cycles of chemotherapy. After clinical and radiographic evaluation, the patient was diagnosed with left-sided empyema. Following thoracocentesis, the aspirated pus sent for bacterial culture yielded pure growth of Proteus mirabilis. Appropriately modified antibiotic therapy with parenteral piperacillin-tazobactam followed by cefixime, tube drainage, and other supportive therapy resulted in a favorable outcome. After three weeks of hospitalization, the patient was discharged for further planned management of his underlying condition. Though uncommon, the possibility of Proteus species should be kept in mind as a causative agent of thoracic empyema in adults, especially in immunocompromised patients with cancer, diabetes, and renal diseases. The so-called common microorganisms of empyema appear to have altered over time, influenced by anticancer therapy and underlying host immune status. Rapid diagnosis and appropriate antimicrobial therapy usually result in a favorable outcome.

Background: Diabetic foot infections are one of the most feared complications of diabetes. This study was undertaken to determine the common aetiological agents of diabetic foot infections and their in vitro antibiotic susceptibility. Methods: A prospective study was performed over a period of one year in a tertiary care hospital. The aerobic bacterial agents were isolated and their antibiotic susceptibility pattern was determined. Members of Enterobacteriaceae were tested for extended spectrum β-lactamase (ESBL) production by combination disc method and staphylococcal isolates were tested for susceptibility to oxacillin by screen agar method. Results: Klebsiella pneumoniae (20.5%), Pseudomonas aeruginosa (17%), Staphylococcus aureus (17%) and Escherichia coli (14.6%) were the most common aetiological agents. Polymicrobial infection was observed in 52% patients. The members of Enterobacteriaceae as well as Pseudomonas spp. and Acinetobacter spp. were found to be susceptible mainly to amikacin, piperacillin-tazobactam and imipenem. Staphylococcus aureus and Enterococcus spp. were susceptible mostly to vancomycin, with varying susceptibility to tetracycline. 56% of the isolates belonging to Enterobacteriaceae were producing ESBL and 65.5% of Staphylococcus aureus were methicillin-resistant. Conclusion: High prevalence of multi-drug resistant pathogens was observed. Amikacin, piperacillintazobactam, imipenem were active against gram-negative bacilli, while vancomycin was found to be active against gram-positive bacteria.
