Evaluation of the in vitro and in vivo antimicrobial activity of alkaloids prepared from Chelidonium majus L. using MRSA- infected C. elegans as a model host
This study aimed to extract alkaloids from C. majus L. (total alkaloids) and evaluate their antibacterial activity both in vitro and in vivo. Reflux extraction was carried out on C. majus L., and the extract was purified with HPD-600 macroporous resin and 732 cation exchange resin exchange columns. Infection modeling of Caenorhabditis elegans (C. elegans) was established to investigate the impact of Methicillin-resistant Staphylococcus aureus (MRSA) and Methicillin-sensitive Staphylococcus aureus (MSSA) on the motility, longevity, and reactive oxygen species (ROS) levels of wild-type worms (N2 strain). The effects of total...

Discovery of a novel class of rosmarinic acid derivatives as antibacterial agents: Synthesis, structure-activity relationship and mechanism of action
Bioorg Chem. 2024 Mar 28;146:107318. doi: 10.1016/j.bioorg.2024.107318. Online ahead of print.ABSTRACTTwenty-seven rosmarinic acid derivatives were synthesized, among which compound RA-N8 exhibited the most potent antibacterial ability. The minimum inhibition concentration of RA-N8 against both S. aureus (ATCC 29213) and MRSA (ATCC BAA41 and ATCC 43300) was found to be 6 μg/mL, and RA-N8 killed E. coli (ATCC 25922) at 3 μg/mL in the presence of polymyxin B nonapeptide (PMBN) which increased the permeability of E. coli. RA-N8 exhibited a weak hemolytic effect at the minimum inhibitory concentration. SYTOX Green assay, SEM...

IL-10 Counteracts IFN- γ to Alleviate Acute Lung Injury in a Viral-Bacterial Superinfection Model
Am J Respir Cell Mol Biol. 2024 Apr 4. doi: 10.1165/rcmb.2023-0437OC. Online ahead of print.ABSTRACTImmune activation is essential for lung control of viral and bacterial infection, but an overwhelming inflammatory response often leads to the onset of acute respiratory distress syndrome (ARDS). Interleukin-10 (IL-10) plays a crucial role in regulating the balance between antimicrobial immunity and immunopathology. In the current study, we have investigated the role of IL-10 in acute lung injury (ALI) induced by influenza A virus (IAV) and methicillin-resistant Staphylococcus aureus (MRSA) coinfection.

CXCR2 perturbation promotes < em > Staphylococcus aureus < /em > implant-associated infection
Conclusion. Our results demonstrate that CXCR2 plays an essential role in regulating the severity of S. aureus implant-associated infections. Interestingly, however, perturbation of CXCR2 expression or signalling both resulted in enhanced Cxcr2 transcription and elevated implant-associated bacterial burdens. Thus, CXCR2 appears finely tuned to efficiently recruit effector cells and mediate control of S. aureus biofilm-mediated infection.PMID:38567642 | DOI:10.1099/jmm.0.001821 (Source: Journal of Medical Microbiology)
