Insights

Diagnosing prosthetic joint infections (PJI) from unusual microbes requires high suspicion and specialized tests. Management is complex, often needing infectious disease specialist collaboration for effective treatment.

Area of Science:

  • Orthopaedic Surgery
  • Infectious Diseases
  • Microbiology

Background:

  • Prosthetic joint infection (PJI) diagnosis and management guidelines often exclude rare causative agents.
  • Zoonotic microorganisms, fungi, and mycobacteria present unique challenges in PJI cases.
  • A comprehensive resource for managing these unusual PJI pathogens is lacking.

Purpose of the Study:

  • To provide a clinical guide for orthopaedic surgeons managing PJI caused by unusual microorganisms.
  • To consolidate information on the presentation and treatment of rare PJI etiologies.
  • To enhance decision-making for complex prosthetic joint infection cases.

Main Methods:

  • Systematic literature review of case reports on PJI.
  • Medline database search for relevant publications.
  • Analysis of diagnostic and management strategies for PJI caused by unusual pathogens.

Main Results:

  • Diagnosis of PJI from unusual microbes frequently requires specialized laboratory tests.
  • Early identification of the causative agent through appropriate testing at débridement is critical.
  • Management strategies are complex and may involve unfamiliar antimicrobial agents.

Conclusions:

  • A high index of suspicion is essential for diagnosing PJI due to zoonotic, fungal, or mycobacterial pathogens.
  • Collaboration with infectious disease specialists is highly recommended for optimal patient outcomes.
  • This review serves as a crucial resource for managing challenging prosthetic joint infections.

Fungal Group Zygomycota

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...
Bacterial Phylum Actinobacteria01:30

Bacterial Phylum Actinobacteria

Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Bacterial Phylum Spirochaetes

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased by a...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
