From a Machine Saw to a Case of Mycobacterium Fortuitum Pyomyositis

Abstract

Pyomyositis is a bacterial infection occurring mainly in skeletal muscles. It is most commonly caused by Staphylococcus aureus with initial symptoms including muscle pain, swelling, and site tenderness. When available, the most accurate technique to determine the extent and the specific location of disease is the magnetic resonance imaging. Successful management includes early recognition, timely surgical debridement or drainage, and appropriate antibiotic therapy. This case report describes a case of Mycobacterium fortuitum pyomyositis in an elderly male associated with challenges of successful diagnosis.

Achromobacter xylosoxidans as emerging pathogen in healthcare settings: A mini review

“…The MRI revealed features consistent with muscle inflammation and abscess formation, which were confirmed by culture and subsequent identification of A. xylosoxidans as the causative agent [31,34]. However, MRI is not typically used as a routine diagnostic tool for A. xylosoxidans infections and is usually reserved for cases with suspected complications or unusual presentations [24].…”

“…It is worth noting that the microorganism has the ability to produce biofilms, enable it to attach on surfaces such as prostheses. This characteristic is a key factor in their pathogenic capacity [17,24].…”

“…Interestingly, hyponatraemia was among the associated comorbidity [30]. The origin of the samples used for diagnosis varied across the studies, such as sputum [30], ear and/or lung swabs [15,22], lung tissue [15,29], and wounds [24]. The diagnostic tools used in the studies were culture-based methods [22,24,29], mass spectrometry [6], and molecular techniques such as polymerase chain reaction (PCR) and genome sequencing [21].…”

The infection can be treated successfully with antibiotics [6,15,17]; however, in others, the outcome may be fatal [16,30].…”

“…The diagnosis of A. xylosoxidans infection typically involves the isolation of the bacterium from a clinical sample, such as blood, sputum, or wound fluid, followed by identification through biochemical tests or molecular methods [22,24,29]. Magnetic resonance imaging (MRI) can be used in some cases to detect the presence of infection in certain areas of the body, such as the brain or soft tissues [31].…”
