Introduction: is a Gram-negative opportunistic human pathogen, which has aroused considerable medical interest for being involved in cases of urinary tract infection.
Aim: Characterize the isolated both in the hospital and in the community.
Methodology: A total of 200 isolated in urine samples from hospital and community were evaluated in biofilm formation assay and hydrophobicity MATS method. Antimicrobial susceptibility was performed through agar-diffusion technique. Virulence and ESBL production genes were observed through the polymerase chain reaction amplification of , and The phylogenetic classification was based on the pattern and and the region TspE4.C2 by PCR Multiplex.
Results: A higher frequency of non-adherent or poorly adherent isolates was observed in the community group. Approximately 85% of the community isolates were distributed in the highest hydrophilicity group (p<0.05). The level of resistant microorganisms was present at the same level in both source (p>0.05). About 14% of the hospital isolates were positive in the ESBL phenotypic detection test (p>0.05). Among the samples, 95% presented ESBL-encoding genes. The predominant phylogenetic group was B2 (78%). Community isolates showed a higher prevalence of virulence genes , and when compared to hospital samples.
Conclusion: These data confirm the worldwide trend that isolates in the community present sometimes higher levels of virulence and antimicrobial resistance.

Improper use of antibiotics has led to the development of antimicrobial resistance, or "superbugs," outpacing the discovery of new antibiotics. The lack of rapid, high-throughput screening methods is a major bottleneck in discovery novel antibiotics. Traditional methods consume significant amounts of samples, making it challenging to discover new antibiotics from limited natural product extracts.

Chemotherapy is essential for treating tumors, including head and neck cancer (HNC). However, the toxic side effects of chemotherapeutic drugs limit their widespread use. Therefore, a targeted delivery system that can transport the drug to the pathological site while minimizing damage to healthy tissues is urgently needed.

Glycogen is a polymer used by bacteria to store excess glucose, playing a crucial role in bacterial growth, stress resistance, biofilm formation, and virulence. In bacteria, the glycoside hydrolase family 13 protein are involved in the synthesis and metabolism of glycogen, respectively. The absence of these enzymes leads to changes in bacterial glycogen content, thereby affecting the growth metabolism of the strain.

Introduction: The mechanism of tannic acid (TA) intervention on methicillin-resistant (MRSA, USA 300) biofilm formation was explored using proteomics.
Methods: The minimum inhibitory concentration (MIC) of TA against the MRSA standard strain USA 300 was determined by two-fold serial dilution of the microbroth. The effects of TA were studied using crystal violet staining.

Introduction And Objective: Elimination irrigation therapy has been proposed as a potential treatment for upper respiratory tract infections, particularly after the COVID-19 pandemic, due to its antiviral properties and mechanical cleansing effects. Additionally, a combination of mineral water with antibiotic therapy has shownto be effective in improving the course clinical infection and positively impact the immune system, potentially enhancing the normal state of microbiota state. The aim of the study is to investigate the influence of elimination-irrigation therapy using a combination of mineral water and ciprofloxacin on the interaction form of individual microbiota species of the upper respiratory tract mucous membrane.
