Summary
Infections around craniofacial implants involve various microbes like Staphylococcus aureus, Gram-negative bacilli, and yeasts. Identifying these pathogens through culture and sensitivity testing is crucial for effective treatment.
Area of Science:
- Oral and Maxillofacial Surgery
- Infectious Diseases
- Microbiology
Background:
- Soft tissue infections around extra-oral craniofacial endosseous implants present a significant clinical challenge.
- Understanding the microbial landscape associated with these infections is essential for appropriate management.
Purpose of the Study:
- To analyze the microflora associated with peri-implant soft tissues in both healthy and infected states.
- To identify potential pathogens contributing to infections around craniofacial implants.
Main Methods:
- Microbiological samples were collected from peri-abutment soft tissues of 18 patients with 49 implants.
- Specimens were cultured on blood agar and selective agars for staphylococci and yeasts.
- Isolates were identified, and antibiotic susceptibility testing was performed.
Main Results:
- No single predominant organism was identified as the cause of peri-abutment skin infections.
- Staphylococcus aureus, Gram-negative bacilli, and yeasts were identified as potential pathogens.
- Microbial findings varied between healthy and diseased implant sites.
Conclusions:
- The microflora associated with craniofacial implant infections is diverse.
- Culture and sensitivity results are critical for guiding the treatment of these infections.
- Targeted antimicrobial therapy based on microbiological data is recommended.

01:27The Skin Microbiota
The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...
01:27The Oral Microbiota
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
01:29Microbiota of the Respiratory Tract
The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
