Advancements in MRSA treatment: the role of berberine in enhancing antibiotic therapy.
BMC Microbiol
December 2024
Department of Clinical Laboratory, Shanghai Eighth People's Hospital, No.8 Caobao Road, Xuhui District, Shanghai, 200235, P.R. China.
Background: Methicillin-resistant Staphylococcus aureus (MRSA) is a significant public health problem. This study investigated the antimicrobial properties and mechanisms of berberine (BBR), a plant alkaloid, against MRSA, evaluating its potential to enhance antibiotic therapy.
Results: Berberine only demonstrated variable but significant inhibitory effects on 50 clinical MRSA strains.

Wound healing is a complex process involving a sequence of factors that can be disrupted, negatively impacting the quality of life for patients and overburdening healthcare systems. Advanced dressings obtained by electrospinning are highlighted by the optimization of this process, allowing air exchange and protection against microorganisms. Aiming to develop bioactive dressings, this study investigated the physicochemical, mechanical, microbiological, and in vitro biological properties of membranes containing 25 %, 50 %, 75 %, and 90 % copaiba oil (CO) co-electrospun with poly(L-co-D,L-lactic acid) (PLDLA) and natural rubber latex (NR).

Antibiotic resistance by methicillin-resistant Staphylococcus aureus (MRSA) is an urgent threat to human health. The biofilm and persister cells formation ability of MRSA and Staphylococcus epidermidis often companied with extremely high antimicrobial resistance. Pinaverium bromide (PVB) is an antispasmodic compound mainly used for irritable bowel syndrome.

Background: The SARS-CoV-2 pandemic and accompanying public health measures disrupted the normal transmission of respiratory viral pathogens. Less is known about the effects on bacterial pathogens.
Aims: To assess the impact of public health restrictions on common respiratory pathogens (influenza viruses, respiratory syncytial virus (RSV) and the following bacterial pathogens: Streptococcus pneumoniae (S.
Magnolol as an Antibacterial Agent Against Drug-resistant Bacteria Targeting Filamentous Temperature-sensitive Mutant Z.
Chem Biodivers
December 2024
State Key Laboratory of Chemical Biology and Drug Discovery, and Department of Applied Biology and Chemical Technology, The Hong Kong Polytechnic University, Hong Kong, P. R. China.
The emergence of multiple drug-resistant bacteria poses critical health threats worldwide. It is urgently needed to develop potent and safe antibacterial agents with novel bactericidal mechanisms to treat these infections. In this study, magnolol was identified as a potential bacterial cell division inhibitor by a cell-based screening approach.
