Summary
Cutibacterium acnes typically causes shoulder infections after surgery. This study reports rare cases of clavicular osteomyelitis caused by C. acnes without implants.
Area of Science:
- Infectious Diseases
- Orthopedic Surgery
- Microbiology
Background:
- Cutibacterium acnes (formerly Propionibacterium acnes) is a common skin flora.
- C. acnes infections are frequently associated with shoulder arthroplasty, often requiring revision surgery.
- Clavicular osteomyelitis is uncommon and typically caused by Staphylococcus aureus.
Observation:
- This report details two rare cases of clavicular osteomyelitis.
- Both cases were caused by C. acnes.
- Neither case was associated with prosthetic implants.
Findings:
- C. acnes can cause clavicular osteomyelitis independently of prosthetic joint infections.
- This finding expands the known spectrum of C. acnes-related bone infections.
- The cases highlight the need to consider C. acnes in non-implant-associated clavicular osteomyelitis.
Implications:
- Clinicians should consider C. acnes in the differential diagnosis of clavicular osteomyelitis, even in the absence of implants.
- Further research may elucidate non-implant-related C. acnes osteomyelitis pathogenesis.
- This expands understanding of C. acnes as a pathogen in orthopedic infections.

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

65.2K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

01:26Defense Mechanism Against Infection
9.7K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

01:26Factors Affecting the Risk of Infection
13.5K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
