Introduction Leclercia adecarboxylata is a ubiquitous aerobic, motile, gram-negative bacilli. The human gastro-intestinal tract is known to harbor this rarely opportunistic microorganism. We describe a rare case of invasive infection with a gastrointestinal starting point due to L. adecarboxylata in a patient with Hirschsprung disease. Case report It is about a newborn female who was admitted on the 3rd day of life to the neonatal intensive care unit for intestinal obstruction. On the 9th day of life, while managing the neonatal obstruction, the patient developed febrile peaks. Cytobacteriological examination of cerebrospinal fluid, blood cultures and culture of umbilical vein catheter allowed the exclusive isolation of Leclercia adecarboxylata . It was producing extended spectrum beta-lactamase and was treated with intravenous imipenem . After favourable evolution, the patient was transferred to the pediatric surgery department. There, she was diagnosed with Hirschsprung disease. Discussion Knowledge of the route of transmission of L. adecarboxylata is limited and the possible source of the infection is unclear. However, the authors describe three hypotheses of contamination of our propositus. In our patient, one or more of these routes of contamination would be possible. Indeed, bacteremia could occur as a result of a bacterial translocation across the mucosal barrier of the colon altered by Hirschsprung disease, antibiotic use and feeding practices. Conclusion Infection with L. adecarboxylata revealed a wide range of infection. It has only recently been acknowledged as an emerging pathogen. Further studies of the pathogenesis and risk factors are required.
The objectives of our work were to establish the epidemiological and bacteriological profile of female urinary tract infection at the Mohammed VI University Hospital of Oujda (Morocco), and then to study the drug resistance of the bacterial strains isolated. This is a retrospective study over 36 months including urine samples from patients hospitalized or consulting at the CHU Mohamed VI of Oujda (Morocco). Urines were processed according to the recommendations of the Medical Microbiology Reference (REMIC) and the EUCAST (European Committee on Antimicrobial Susceptibility Testing). We collected 12556 requests for CBEU from different departments. At the top of the list was the emergency department with a rate of 37% (n= 4666) followed by outpatient clinics (33.1%; n=4226). 5% (n=630) of the CBEU were positive. Escherichia coli (E. coli ) dominated the epidemiological profile with a rate of 72.50% (n=482). E. coli was resistant to penicillins in 69.50% (n=299) of cases, protected penicillins in 34.80% (n=149), third generation cephalosporins (C3G) in 9% (n=38), fluoroquinolones in 17.5% (n=73), Trimethoprim-Sulfamethoxazole in 46% (n=196) of cases and gentamicin in 12% (n=51) of cases. None of the strains were resistant to carbapenems. Awareness-raising on the proper use of antibiotics, issuing national recommendations for the treatment of urinary tract infections in order to standardize therapeutic regimens. Effective control of these infections requires a global prevention strategy that implies close collaboration between epidemiologists, clinicians, bacteriologists, hygienists and the health care team.
Background: Due to its incidence, clinical polymorphism and severity, urinary tract infection is an important problem in elderly. The objectives of the authors’ work were to establish the bacteriological profile of urinary tract infection and/or colonization in the elderly and then to study drug resistance of bacterial strains isolated. Materials and methods: This is a 36 months retrospective study from 22 March 2016 to 11 May 2019. The study included urinary specimens of persons aged 65 years or over, hospitalized or consulting at the authors’ hospital. Urines were processed according to the recommendations of the medical microbiology reference system and European Committee on Antimicrobial Susceptibility Testing. Results: The authors collected 6552 requests for cytobacteriological examination of urine. Most of the specimens was collected in the middle stream (n=5503; 84%). Cultures were sterile in 49.77% of cases. Positive in 50.22% of cases. Among positive samples we had 53.41% polymorphic cultures, 32.75% urinary tract infection, and 13.82% urinary tract colonization. Gender distribution showed a sex ratio at 0.62. Gram-negative bacilli, with Escherichia coli as the main species, dominated the isolated bacteria. Resistance rates of E. coli strains that we isolated were 70% for amoxicillin, 36.31% for amoxicillin-clavulanate and 25% for ciprofloxacin. A high resistance rate was seen for third generation cephalosporins. Least resistance recorded to nitrofurantoin. Conclusion: ITU in the elderly is diverse and significantly different from that of younger patients, through its high contamination rate, difficulty in acquiring clinical information, high rate of asymptomatic bacteriuria, and high proportion of multidrug resistant bacteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
