Unlabelled: The evolution of multidrug resistance remains an alarming topic due to selection pressure related to the inappropriate use of antibiotics.
Objectives: Our work is in this perspective and focuses on the evolution of the consumption of antibiotics active on gram-negative bacilli, and the evolution of bacterial resistance.
Materials And Methods: International indicator of antibiotic consumption was based on the method of Defined Daily Dose reported to the number of days of hospitalization. The search for a correlation between bacterial resistance and antibiotic consumption was conducted by the Spearman test.
Results: A statistically significant correlation was identified between the rates of enterobacteriaceae resistant to 3(rd) generation cephalosporin, particularly those secreting beta-lactamases with extended spectrum, and consumption of 3(rd) generation cephalosporin (p= 0.002) and imipenem (p= 0.04). Also, a statistically significant relationship between the multi-resistant bacteria and the rate of consumption of colistin (p= 0.041) and fluoroquinolones (p= 0.002) was also reported in this study.
Conclusion: Monitoring of both evolution of multidrug resistance and the use of antibiotics helps us to better understand the situation and establish more efficient antibiotic protocols.

Antimicrobial resistance (AMR) is an escalating global health concern that results in approximately 700,000 deaths annually owing to drug-resistant infections. It compromises the effectiveness of conventional antibiotics, as well as fundamental medical procedures, such as surgery and cancer treatment. Phytochemicals, natural plant constituents, and biogenic nanoparticles synthesized through biological processes are pharmacological alternatives for supplementing or replacing traditional antibiotics.

Helicobacter pylori (H. pylori) is the primary etiological agent of gastric adenocarcinoma, which affects over 60% of the global population, with a significant prevalence in Latin America. Given its impact on the affected population, it is crucial to understand the diagnostic tools available for detecting this infection.

Tuberculosis (TB) continues to be a major cause of death worldwide despite having an effective combinatorial therapeutic regimen and vaccine. Being one of the most successful human pathogens, retains the ability to adapt to diverse intracellular and extracellular environments encountered by it during infection, persistence, and transmission. Designing and developing new therapeutic strategies to counter the emergence of multidrug-resistant and extensively drug-resistant TB remains a major task.

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.

Antimicrobial-resistant bacteria are particularly prevalent in Southeast Asia, mainly due to inadequate infection prevention and control (IPC) and the widespread and uncontrolled use of antibiotics. Pakistan is the third largest low-middle-income country (LMIC) user of antibiotics. Antibiotic consumption increased by 65%, from 800 million to 1.
