“…These atypical pathogens, including Staphylococcus aureus, Pseudomonas aeruginosa and different members of the family Enterobacteriaceae, are known to possess virulence factors that could account for the accelerated tissue destruction characterizing GAP. Recent studies by our group have shown higher Staphylococcus aureus oral carriage rates in periodontitis affected patients as compared to healthy controls (8). Moreover, we showed that isolation of S. aureus from subgingival sites of GAP positively correlates with disease progression, with higher levels of inflammatory mediators and with faster periodontal breakdown (9).…”

Staphylococcus aureus is an opportunistic pathogen causing dental infection and systemic infections in human body. This organism decreases susceptibility to several types of antibiotics every day and becomes more resistant which is a growing sense of concern in this era. Considering this fact, the study was attempted to characterize the S. aureus from human dental infection and to determine the antibiogram profile of isolates. Sixty four (64) samples were collected from the patients with dental infection who visited different dental clinics and hospitals in Mymensingh, Bangladesh for treatment. Isolation and identification of S. aureus were conducted by using cultural, morphological, and biochemical characteristics. Polymerase chain reaction was performed for final confirmation of S. aureus followed by detection of methicillin resistant S. aureus (MRSA) targeting mecA and mecC genes. Antibiotic susceptibility test of isolated bacteria was tested against seven antibiotics by disk diffusion methods. Forty isolates among 64 samples were found positive for S. aureus based on cultural characteristics. Among them 30 isolates were found positive in coagulase test. Depending on the result of coagulase test, all the 30 isolates were subjected to antibiotic sensitivity test and among them 25 were 100% resistant to penicillin, ampicillin and amoxicillin. All the 25 isolates were subjected to polymerase chain reaction (PCR) to identify methicillin resistant gene mecA and mecC. Eight isolates were positive for mecA gene while no isolates were positive for mecC. The present findings conclude that S. aureus is prevalent in dental infections and contain methicillin resistant genes.

“…Among sites that are frequently colonized by S. aureus, the oral cavity (7,8) is actually receiving attention also as the reservoir for different types of infections (9). We have recently shown that patients affected by periodontal disease, host S. aureus in their mouth at higher rates than subjects who are periodontally healthy, and that S. aureus strains isolated from periodontally affected patients are more toxigenic than those isolated from healthy subjects (10). Those experiments were aimed at evaluating the effect of changing oral conditions on the status of S. aureus oral carrier and on the possibility that these conditions could promote the diffusion of severe systemic infections.…”

Isolation of Staphylococcus Aureus and Progression of Periodontal Lesions in Aggressive Periodontitis

This work evaluates whether isolation and toxicity of subgingival Staphylococcus aureus strains correlate with progression of periodontal lesions and whether isolates are characterized by a specific genomic background. The study involved 165 subjects affected by generalized aggressive periodontitis. Three sets of samples of supragingival and subgingival plaque were obtained at 45-day intervals from active and non-active sites, to detect S. aureus. Susceptibility to antibiotics, the presence of 17 genes, genomic restriction profiles and multilocus sequence typing (MLST) were performed to characterize all isolates. S. aureus was detected in 37.6% of the subjects. Subgingival colonization rates were 66.1% and 12.9% for active and non-active sites, respectively (P
