In this controlled before-after study, wound swabs were only processed for culture, identification, and susceptibility testing if a quality metric, determined by the Q score, was met. Rejection of low-quality wound swabs resulted in a modest decrease in reflexive antibiotic initiation while reducing laboratory workload and generating few clinician requests.

was first described in humans in 1954, known to infect fish species and contaminate water and fish products. Inoculation to humans occurs through injured skin resulting in the formation of a solitary nodule known as "fish tank granuloma." Disseminated infections have been reported in the immunocompromised and can present with extracutaneous manifestations such as arthritis and osteomyelitis.

While screening the rectal site and urine may be appropriate for detection of carbapenemase-producing Enterobacterales, respiratory samples, throat and wound swabs may increase the sensitivity of screening protocols when aiming to detect colonization with carbapenemase-producing non-fermenting bacteria. Our results support the need for tailoring screening recommendations according to the bacterial species targeted.

Objective: Staphylococcus aureus (SA), including methicillin-resistant strains (MRSAs), is a major cause of skin and soft tissue infections (SSTIs) in military populations. This study investigated SSTI incidence and SA carriage in a military training site over 16 weeks using a prospective observational cohort design.

Methods: Two training cohorts provided pre- and post-training self-collected swabs for bacterial carriage, and environmental swabs from accommodations, personal items, and training facilities.

Background: During this study, six isolates of multiple antibiotic resistant Staphylococcus aureus bacteria were obtained from different clinical specimens (burn swabs, urinary tract infections, wound swabs): three isolates from burns, two isolates from urinary tract infections, and one isolate from wound swabs. They were obtained from private laboratories in Baghdad from 1/1/2023 to 3/15/2023.

Method: The diagnosis of these isolates was confirmed using the Vitek2 device.

An ambulance used by an emergency medical service team is the workplace of specialised medical personnel, providing daily transportation for patients in life-threatening conditions, from all walks of life, with numerous diseases and injuries. MRSA (methicillin-resistant ) strains are classified as Gram-positive cocci, characterised primarily by their multidrug resistance. Infections caused by have a low treatment success rate and are associated with persistent carrier state.
