Among 204 strains isolated from infected burn wounds of 188 patients in the years 1987-1989 resistance to methicillin and oxacillin was found in 116 Staphylococcus aureus strains (group A). They accounted for 56.6% of the isolates. These data were compared with those of 1815 strains isolated from surgical cases in which 901 were MORSA strains (group B). In both groups MORSA were tested for their sensitivity to 9 various antibiotics. They were most sensitive to vancomycin and cefamandole.

Anti-inflammatory coupled anti-angiogenic airway stent effectively suppresses tracheal in-stents restenosis.

J Nanobiotechnology

Excessive vascularization during tracheal in-stent restenosis (TISR) is a significant but frequently overlooked issue. We developed an anti-inflammatory coupled anti-angiogenic airway stent (PAGL) incorporating anlotinib hydrochloride and silver nanoparticles using advanced electrospinning technology. PAGL exhibited hydrophobic surface properties, exceptional mechanical strength, and appropriate drug-release kinetics.

Department of Respiratory Medicine, Anting Hospital of Jiading District, 1060 Hejing Road, Anting Town, Jiading District, Shanghai, 201805, China.

Background: Respiratory tract infections (RTIs) are one of the leading causes of morbidity and mortality worldwide. The increase in antimicrobial resistance in respiratory pathogens poses a major challenge to the effective management of these infections.

Objective: To investigate the distribution of major pathogens of RTIs and their antimicrobial resistance patterns in a tertiary care hospital and to develop a mathematical model to explore the relationship between pathogen distribution and antimicrobial resistance.

Background: The excessive use of antibiotics is a major contributor to the global issue of antimicrobial resistance (AMR), a significant threat to human and animal health. Hence, assessing new strategies for managing Multi-Drug Resistant (MDR) microorganisms is vital. In this study, the use of mechanically isolated mature adipose cells (MIMACs) and their lysate (Adipolysate) as a new sustainable antimicrobial agent was assessed against Methicillin-resistant Staphylococcus aureus (MRSA).

The current study was designed to evaluate the antibacterial, antibiofilm, and biofilm inhibitory potential of six medicinal plants, including Trachyspermum ammi, Trigonella foenum-graecum, Nigella sativa, Thymus vulgaris, Terminalia arjuna, and Ipomoea carneaid against catheter-associated bacteria (CAB). Eighteen CAB were identified up to species level using 16S rRNA gene sequencing, viz., Klebsiella pneumoniae, Staphylococcus aureus, and Pseudomonas aeruginosa.
