Summary
Septic arthritis and osteomyelitis of the finger caused by Mycobacterium marinum are rare infections. Early diagnosis and appropriate treatment with antibiotics or surgery are key for successful outcomes in these joint infections.
Area of Science:
- Infectious Diseases
- Rheumatology
- Orthopedic Surgery
Background:
- Mycobacterium marinum is an atypical mycobacterium commonly found in aquatic environments.
- Joint infections, including septic arthritis and osteomyelitis, are rare but serious complications of M. marinum exposure.
Observation:
- A case of septic arthritis and osteomyelitis of the ring finger caused by Mycobacterium marinum is presented.
- Literature review reveals fewer than 40 reported cases of M. marinum joint infections.
- Patients typically have a history of contact with fish or aquatic activities and present with insidious hand or wrist arthritis.
Findings:
- Delayed diagnosis and treatment with intraarticular steroids are common pitfalls.
- Prompt diagnosis and appropriate management, including antibiotics and/or surgical debridement, lead to successful outcomes.
Implications:
- Highlights the importance of considering Mycobacterium marinum in the differential diagnosis of hand and wrist arthritis, especially in individuals with relevant exposure history.
- Emphasizes the need for timely and accurate diagnosis to avoid complications and ensure effective treatment.
- Underscores the efficacy of antibiotic therapy and surgical intervention in managing M. marinum-induced joint infections.

01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
01:25Mechanism of Antibiotic Resistance in MRSA
Antibiotic resistance in bacteria arises when microorganisms evolve the ability to withstand drugs designed to kill them or inhibit their growth, rendering once-effective treatments useless. This phenomenon, driven by genetic change and selection under antibiotic exposure, poses a profound threat to modern medicine. Mechanisms include drug-inactivating enzymes (e.g., β-lactamases), efflux pumps that eject antibiotics, mutations altering antibiotic targets, decreased drug uptake, and acquisition...
01:25Clinical Significance of Antibiotic Resistance
Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
01:26Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
