Decolonisation of patients colonised with meticillin-resistant Staphylococcus aureus (MRSA) is one of the recommended methods for controlling MRSA in hospitals but there is a limited choice of agents that can be used. Octenidine dihydrochloride is a relatively new antiseptic that has been used for MRSA decolonisation in some countries. On reviewing available literature on its use for MRSA decolonisation, only four observational studies were found. All of these were small studies, which differed in study design. MRSA decolonisation rates of 6-75% have been reported. Patients with wound colonisation were included in these studies but it was not clear if the hair was treated in two of these. Octenidine appears to be as effective as chlorhexidine for MRSA decolonisation with fewer adverse effects, but large randomised trials incorporating octenidine as a skin disinfectant for MRSA decolonisation need to be undertaken to confirm its usefulness in clinical settings.

Background: Patients undergoing cardiac surgery are identified as high risk for infection, including MRSA. An outbreak of MRSA was identified when two patients experienced MRSA infection concurrently in a cardiothoracic high dependency unit with uncommon detection of MRSA previously and an established screening programme.
Methods: An outbreak control team was convened and interventions applied including refresher training in hand and environmental hygiene, review of practice with regard to aseptic access of medical devices and consideration of antibiotic use in the unit.

Methods: This retrospective population-based cohort study included MRSA throat carriers between July, 2018 and June, 2019, in the Capital Region of Denmark.
Recurrent skin and soft tissue infections (SSTIs) in three family members caused by methicillin-resistant (MRSA) with Panton-Valentine leukocidin (PVL) exotoxin.

Article Synopsis
- Three family members experienced repeated skin and soft tissue infections (SSTIs) over a span of three months, including conditions like paronychia and abscesses that needed surgical drainage.
- A definitive diagnosis of methicillin-resistant Staphylococcus aureus (MRSA) carrying the Panton-Valentine leukocidin (PVL) exotoxin was only made after two family members were hospitalized simultaneously with severe abscesses.
- After implementing MRSA decolonisation therapy with mupirocin and octenidine, only one family member had a subsequent recurrence, emphasizing the importance of considering MRSA in families with similar SSTI issues and ensuring proper treatment to prevent further cases.

Methicillin-resistant (MRSA) causes a variety of healthcare-associated and community-acquired infections. Due to limited availability of effective antimicrobials for treating MRSA infections, there is a growing need to explore alternative therapeutic approaches. Here, the antimicrobial activities of 19 oils, popularly used for their medicinal properties, were tested against MRSA USA300.
