Two cases of osteomyelitis due to group G streptococcus
1Division of Infectious Diseases and Epidemiology, Department of Medicine, The Milton S Hershey Medical Center, University Hospital, The Pennsylvania State University, Hershey, Pennsylvania, USA.
Summary
Group G streptococcal osteomyelitis is rare in adults, even in healthy individuals. Successful treatment was achieved using parenteral penicillin G, highlighting its efficacy against this infection.
Area of Science:
- Infectious Diseases
- Bacteriology
- Orthopedics
Background:
- Osteomyelitis, a bone infection, is typically caused by Staphylococcus aureus.
- Group G Streptococcus is an uncommon pathogen for osteomyelitis, with limited prior reports.
- Previous cases of Group G streptococcal osteomyelitis have primarily involved specific risk groups, such as intravenous drug users.
Purpose of the Study:
- To report two new cases of group G streptococcal osteomyelitis in adult patients.
- To highlight the successful treatment outcomes for these cases.
- To contribute to the limited existing literature on this rare condition.
Main Methods:
- Case report presentation of two adult patients diagnosed with group G streptococcal osteomyelitis.
- Description of the clinical presentation and diagnostic findings for each case.
- Documentation of the treatment regimen, focusing on parenteral aqueous penicillin G administration.
Main Results:
- Two adult patients with group G streptococcal osteomyelitis were identified.
- One patient was otherwise healthy, expanding the known demographic profile for this infection.
- Both patients demonstrated successful treatment outcomes with parenteral aqueous penicillin G.
Conclusions:
- Group G streptococcal osteomyelitis can occur in healthy adults.
- Parenteral aqueous penicillin G is an effective treatment for group G streptococcal osteomyelitis.
- Further research and case reporting are warranted to better understand this rare infection.

01:25Endocarditis I: Introduction
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
01:29Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
01:26Healthcare 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. Common...

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...
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...
01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
