Article Abstract
Objective: To explore the presence of bacterial biofilms (BF) in patients with CRS and the effect of BF on clinical symptoms and postoperative outcomes.
Methods: Seventy-two patients with chronic sinusitis were enrolled in this study. The control group included 15 patients with deviation of the nasal septum and 10 patients had a fracture of the nasal bone. Mucosa of the uncinate process or ethmoid near the ostium of the maxillary sinus was obtained during endoscopic sinus surgery. The specimens were subjected to scanning electron microscopy. Patients were followed for 1 year and observed by the Lund-Kennedy endoscopy, and the Haikou standard classification (ESS-1997). Statistical analysis was performed by t-test or chi-square test.
Results: Three patients were lost to follow-up. The scanning electron microscopy analysis showed bacterial biofilms in 49 of the 69 patients with chronic sinusitis. A marked destruction of the epithelium and cilia was observed in samples positive for bacterial biofilms. No bacterial biofilms were detected in the control group, and scanning electron microscopy showed normal epithelium and cilia in those specimens. There was no significant difference in gender, classification or duration of disease between the BF(-) and BF(+) groups. At six months and one year postoperative, the Lund-Kennedy endoscopy scores for CRS patients with BF (4.78 +/- 1.67; 4.55 +/- 1.61) were significantly higher than those without BF (3.65 +/- 1.39; 3.65 +/- 1.18) (t = -2.654, P < 0.01; t = -2.264, P < 0.05). Based on the Haikou standard classification, there was a significantly difference between patients with BF and those without BF (chi2 = 18.014, 22.063, P < 0.001, respectively).
Conclusions: Different life stages of bacterial biofilms were demonstrated to be present in CRS. Gender, classification or duration of disease did not affect the presence of bacterial biofilms in patients with CRS. There is a correlation between bacterial biofilms and an unfavorable outcome in patients with CRS after ESS.

Gut mucosal immunity of teleost is mainly governed by mucosa-associated lymphoid tissues (MALT) and indigenous microbiota on mucosal surfaces of gut tract, which can confer protection against pathogenic invasion. However, the probiotic features of bacterial isolates from gut tract of triploid cyprinid fish (TCF) were largely unclear. In this study, Lysinibacillus and Enterobacter strains were isolated for probiotic identification.

MRSA's resistance poses a global health challenge. This study investigates lysine succinylation in MRSA using proteomics and bioinformatics approaches to uncover metabolic and virulence mechanisms, with the goal of identifying novel therapeutic targets. Mass spectrometry and bioinformatics analyses mapped the MRSA succinylome, identifying 8 048 succinylation sites on 1 210 proteins.

N-acyl l-homoserine lactones are signaling molecules used by numerous bacteria in quorum sensing. Some bacteria encode lactonases, which can inactivate these signals. Lactonases were reported to inhibit quorum sensing-dependent phenotypes, including virulence and biofilm.

Clavibacter michiganensis (Cmm), designated as an A2 quarantine pest by the European and Mediterranean Plant Protection Organization (EPPO), incites bacterial canker of tomato, which presently eludes rapid and effective control methodologies. Dense biofilms formed by Cmm shield internal bacteria from host immune defenses and obstruct the ingress of agrochemicals. Even when agrochemicals disintegrate biofilms, splashing and bouncing during application disperse active ingredients away from target sites.

Pseudomonas aeruginosa is a Gram-negative bacterium that is notorious for airway infections in cystic fibrosis (CF) subjects. Bacterial quorum sensing (QS) coordinates virulence factor expression and biofilm formation at population level. Better understanding of QS in the bacterium-host interaction is required.
