Purpose: The purpose of this study was to evaluate the bacterial adherence to high--tensile strength suture materials using a bioluminescent in vitro model.
Methods: Eleven strands each of No. 2 MaxBraid (Arthrotek [Biomet], Warsaw, IN), FiberWire (Arthrex, Naples, FL), Ethibond (Ethicon, Somerville, NJ), Orthocord (DePuy Mitek, Raynham, MA), and silk (Ethicon) sutures were immersed in a broth of bioluminescent Staphylococcus aureus, which is genetically engineered to emit photons. After 12 hours in the broth, the suture strands were individually irrigated with 10 mL of low-pressure normal saline solution and imaged with a photon-capturing camera system that yields a total photon count that correlates directly with residual bacterial counts.
Results: MaxBraid had the greatest adherence, followed by FiberWire, Ethibond, Orthocord, and silk. Orthocord had only 25% of the bacterial adherence of MaxBraid (P < .001). Ethibond and FiberWire had 53% (P < .001) and 75% (P = .003) of the adherence of MaxBraid, respectively. Differences between each suture were also statistically significant, with Ethibond and Orthocord having 71% (P = .007) and 33% (P < .001) of the adherence of FiberWire, respectively, and Orthocord having 47% (P < .001) of the adherence of Ethibond. The adherence to silk was statistically lower than all of the high-tensile strength sutures.
Conclusions: Among high--tensile strength sutures, Orthocord has significantly less bacterial adherence than MaxBraid and FiberWire. Although infections in arthroscopic shoulder surgery are rare, the physical properties of surgical implants should be known by surgeons. In addition, bacterial adherence may contribute to suture selection in a patient prone to infection or to the use of suture in other body areas at greater risk for contamination.
Clinical Relevance: Bacterial adherence to high--tensile strength sutures may be a useful factor in implant selection in a patient with predisposition for contamination or infection.

Ultrasound is a key diagnostic tool in modern medicine due to its ability to provide real-time, high-resolution images of the internal structures of the human body. Despite its undeniable advantages, there are challenges related to the contamination of ultrasound probes, with the risk of healthcare-associated infections. The aim of this review was to identify the most effective disinfectants for disinfecting ultrasound probes to prevent the transmission of pathogens between patients.

Despite MCT oil's potential antimicrobial benefits for gastrointestinal health, its effects on disrupting cariogenic pathogens on oral mucosal surfaces remain underexplored. This study evaluated the impact of MCT oil on the adhesion and invasion of and using planktonic and mucosal models. First, a planktonic model was used to assess the impact of various concentrations of MCT on the growth of and .

Bacterial attachment and biofilm formation are associated with the contamination and fouling at several locations in a washing machine, which is a particularly complex environment made from a range of metal, polymer, and rubber components. Microorganisms also adhere to different types of clothing fibres during the laundering process as well as a range of sweat, skin particles, and other components. This can result in fouling of both washing machine surfaces and clothes and the production of malodours.

Background: Wound infections significantly impact morbidity, mortality, and healthcare costs globally. The Kashmir Valley's unique geographical and climatic conditions, coupled with resource constraints and antibiotic misuse, complicate managing these infections effectively. This study aimed to identify predominant bacterial pathogens in wound infections at a tertiary care hospital in Kashmir, determine their antibiotic susceptibility profiles, and estimate the prevalence of multidrug-resistant (MDR) strains.
