A basic and extensively conserved bacterial communication mechanism, quorum sensing (QS) allows for precise gene expression coordinating in response to cell population density. The creation, release, accumulation, and detection of particular signaling molecules called autoinducers mediate this control. Once a threshold concentration is achieved, these molecules cause behavioral changes in the entire population. Here, we provide a thorough evolutionary analysis of QS systems in a wide range of bacterial taxa, including archaeal, Gram-positive, and Gram-negative lineages.We clarify the evolutionary origins, diversification paths, and adaptive adaptations that have molded QS networks by an integrated approach that combines comparative genomic research, phylogenetic reconstruction, and functional characterization. With significant heterogeneity in gene content, signaling circuits, and autoinducer usage among strains, the results show that both vertical inheritance and horizontal gene transfer are important factors in the distribution of QS genes. These changes are a result of ecological adaptation to various settings that are impacted by QSinhibitory chemicals, temperature, pH, nutrition availability, and interspecies interactions.The evolutionary dynamics and structural and functional variety of QS systems are demonstrated by in-depth case studies of Vibrio harveyi, Staphylococcus aureus, and Pseudomonas aeruginosa. Clinical evidence supports QS's potential as a target for next-generation antiinfective treatments by demonstrating that it regulates virulence, biofilm formation, and antibiotic resistance. Furthermore, QS modulation has promising biotechnological uses in microbial engineering, synthetic biology, food safety, and agriculture. All things considered, this work gives an evolutionary framework for comprehending bacterial QS systems and insights into how to use them for both industrial advancements and medicinal interventions

Due to its therapeutic and preventive uses, especially in the treatment of chronic illnesses and during pregnancy, high-dose folic acid supplementation has drawn attention from all over the world. Despite being widely regarded as safe, high folic acid consumption has sparked growing concerns about possible impacts upon the usual bacteria in the stomach. Because it aids in immunological regulation, food metabolism, and pathogen defense, the gut microbiota is vital to human health. The research that is now available, however, indicates that this balance might be upset by supraphysiological folic acid intake. High doses of folic acid have been shown in both clinical and experimental investigations to suppress beneficial bacterial species like Lactobacillus and Bifidobacterium, decrease microbial diversity, and increase dysbiosis. Intestinal barrier function, host-microbe interactions, and disease susceptibility may all be affected by such changes. However, high-dose supplementation may be beneficial for some pathological diseases, such as cardiovascular illnesses, pregnancy-related difficulties, and folate insufficiency. This duality emphasizes how folic acid interacts with the gut microbiota to shape host health in a complicated way. Given how common fortified foods and supplements are, more research is desperately needed to understand dose-dependent effects, determine safe supplementation limits, and investigate the long-term impacts of changes in the gut microbiota.

The precise and quick identification of pathogenic microorganisms remains a critical component of efficient clinical diagnostics and antimicrobial stewardship. Traditional culture-based approaches, while reliable, are time-consuming and may not discover fastidious or slow-growing organisms. In this study, we investigated the diagnostic synergy between 16S rRNA gene sequencing, the molecular gold standard for bacterial identification, and the novel vitek-2 technology, a fast, culture-independent platform based on metabolic profiling. Our goal was to determine the combined performance of these techniques in recognizing both pure isolates and complicated clinical specimens, such as sputum samples. Studies showed that combining the sequencing of 16S rRNA with vitek-2 dramatically shortened diagnostic turnaround time, with bacterial identification completed in 30-72 hours, compared to the typical delays of standard methods. Vitek-2 high sensitivity, automation, and ease of use enhanced the genotypic precision of 16S rRNA analysis, particularly in detecting polymicrobial illnesses and distinguishing between closely connected species. Furthermore, the combination treatment was effective in a variety of clinical settings, including cases of subacute endocarditis and pneumonia with negative cultures. This study demonstrates the potential of a hybrid diagnostic strategy that combines high-throughput sequencing with quick metabolic detection to increase diagnostic accuracy and timeliness in microbiology laboratories. Future plans include expanding this platform to cover fungal and viral targets, improving automation, and testing the system across a larger patient population. The 16S- vitek-2 synergy is a promising improvement in next-generation diagnostics, capable of guiding more targeted therapeutics and improving patient outcomes.

Antibacterial activity of the aqueous and oily extracts of some plant against strains of staphylococcus spp. and pseudomonas aerginosa from chalazion

Aims: Aqueous and oil extracts for cloves, lemon peels, garlic and rosemary are examined for antimicrobial activity against many pathogenic bacteria isolated from chalazion. Methodology and results: Different plant extracts were used starting from 0.020-0.66 g/mL with minimum inhibitory concentration. Notably, all plant extracts have been purified via the Soxhlet unit technique. Also, the active ingredients were identified by highinerformance liquid chromatography (HPLC), which determined three different effective compounds: eugenol, gallic acid and dimethoxyphenol at clove oil extract, while at water extract was apigenin only. The results indicated that the extracts exhibited an inhibition zone has 15 mm at a concentration of 0.165 mg/mL for all pathogenic bacteria isolates. Conclusion, significance and impact of study: The extract is considered an effective treatment for various bacterial infections of chalazion because many causative agents have been identified as resistant to antibiotics.

Chalazion is a common infection of the meibomian gland in all ages' eyelids. The current study sought to isolate and identify bacteria linked with chalazion in patients hospitalized to Mosul hospitals between 10/1/2021 and 1/3/2022. Samples were obtained using swabs soaked in the transport media (amies), and bacteria were identified using traditional methods with API20E. Vitek-2 and molecular approaches based on the 16 S rRNA gene verified the species-level diagnosis. Using BLAST software, the nitrogen base sequences were determined and compared to those of the NCBI. The results showed that Staphylococcus aureus was isolated by 52.2% and 62.5% among women, notably in the age (21-40) years, and by 27.8% for females and 19.2% for the same age group in males, and upper eyelid infection predominated. The infection rate in people with oily skin was 50.9% in females and 34.6% in men, with the presence of the agr A, agrC, and agrD genes in isolates that exhibited a positive result in the Congo red medium and microtiter plate.
