Purposes: The aim of our study was to determine the prevalence of multiresistant germs with nosocomial potential and their main resistance phenotype and genotype patterns in surgical departments.
Methods: Identification of germs was performed by the API system (BioMerieux France) and susceptibility tests by disk-diffusion tests, (CLSI standards) with automatic reading methods (Osiris-Bio Rad Laboratories). ESBL producing E. coli and Klebsiella pneumoniae strains have been also genotyped.
Results: From 190 samples (urines, wound secretions, blood, etc.); we isolated 106 microbial strains with nosocomial potential. 56 (52.83%) from these strains were represented by enterobacteria, 26 (24.52%) by Gram negative non-fermentative rods, and 24 (22.64%) by Gram positive cocci.
Conclusions: We noticed a high prevalence of multidrug resistant germs (ESBL, MRSA, etc). The majority of them were involved in nosocomial surgical site and urinary tract infections.

Background: Nosocomial pneumonia is common in trauma patients and associated with an adverse prognosis. We recently externally validated and recalibrated an existing formula to predict nosocomial pneumonia risk. Identifying more potential predictors could aid in a more accurate prediction of nosocomial pneumonia risk in level-1 trauma patients.

Unlabelled: , an opportunistic and notorious nosocomial pathogen, is responsible for many infections affecting soft tissues, skin, lungs, bloodstream, and urinary tract, accounting for more than 722,000 cases annually. Despite the numerous advancements in therapeutic options, no approved vaccine is currently available for this particular bacterium. Consequently, this study focused on creating a rational vaccine design using bioinformatics tools.

Sepsis is characterized by a concomitant early pro-inflammatory response by immune cells to an infection, and an opposing anti-inflammatory response that results in protracted immunosuppression. The primary pathological event in sepsis is widespread programmed cell death, or cellular self-sacrifice, of innate and adaptive immune cells, leading to profound immunological suppression. This severe immune dysfunction hampers effective primary pathogen clearance, thereby increasing the risk of secondary opportunistic infections, latent viral reactivation, multiple organ dysfunction, and elevated mortality.

Objectives: KLUC β-lactamase is a minor extended-spectrum β-lactamase (ESBL) derived from chromosome-encoded cefotaximase in Kluyvera cryocrescens. This study aimed to characterize the genetic context of KLUC-3-producing Escherichia coli and bla-harboring plasmids and assess nosocomial transmission.
Methods: In a national genomic surveillance conducted in 2019 and 2020, KLUC-3-producing E.

Department of Infectious Diseases, Tianjin, P.R. China.
Objective: This study aims to estimate the overall incidence of surgical site infections (SSIs) after cesarean section (CS) and the influencing factors in the Chinese population.
Materials And Methods: The study searched all relevant literature in English and Chinese search databases (English search bases: PubMed, Embase, Cochrane Library, Web of Science; Chinese search bases: China National Knowledge Infrastructure, Wanfang, and China Science and Technology Journal Database) up to March 19, 2024, according to the search strategy. A random/fixed effects model was decided on the basis of the I statistic assessing the magnitude of study heterogeneity, and publication bias was assessed using the Begg's test.
