Summary
A rare multifocal pyomyositis caused by non-haemolytic streptococci occurred in a woman with a history of Staphylococcus aureus pyomyositis. Successful treatment involved surgical drainage and antibiotics.
Area of Science:
- Infectious Diseases
- Microbiology
- Musculoskeletal Infections
Background:
- Pyomyositis is a bacterial infection of muscle, typically Staphylococcus aureus.
- Non-tropical pyomyositis is less common and can be caused by various bacteria.
- Previous infections and inflammatory conditions may predispose individuals to recurrent or multifocal infections.
Observation:
- A 36-year-old woman presented with multifocal pyomyositis.
- The initial infection site was contused muscle in the left anterior thigh.
- The infection spread to the contralateral femoral and gluteal muscles.
Findings:
- Cultures identified non-haemolytic streptococci as the causative agent.
- The patient had a history of Staphylococcus aureus pyomyositis and ulcerative colitis.
- The multifocal nature of the infection was unusual for streptococcal pyomyositis.
Implications:
- This case highlights non-haemolytic streptococci as a potential cause of multifocal pyomyositis.
- It underscores the importance of considering diverse pathogens in recurrent or multifocal pyomyositis.
- Prompt surgical intervention and appropriate antibiotic therapy are crucial for successful management.

01:30Bacterial 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...
01:30Bacterial 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...
01:24Bacterial Phylum Tenericutes
The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...
01:27Streptococcal Pharyngitis
Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
01:28Diphtheria
Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
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...
