| Abstract | ||
| Background: In Egypt and around the world, oral infections continue to be a major public health concern. The difficulties in accurately identifying the causative bacteria frequently make it difficult to manage these illnesses effectively. Objective: The study aimed to isolate and identify the prevalent microorganisms associated with oral cavity infections in patients admitted to a specific dental clinic and an educational hospital in Egypt. Clinical materials from patients with symptoms of oral cavity infections in both genders and age groups at a particular dental clinic in Beni Suef, Egypt, and Qasr Al Aini Hospital in Cairo were obtained. Methodology: A total of 100 microbial isolates were recovered from 100 clinical specimens. A variety of techniques for identifying the isolated microorganisms were used, including, traditional biochemical approaches (example: culture characterization), and Vitek 2 systems bioMérieux methods. Results: Microbes were more prevalent in male patients (63%) than in female patients (37%). Six Gram-positive bacteria (Streptococcus mutants, n = 35%), Staphylococcus aureus, n = 17%), Enterococcus faecalis, n = 8%, Kocuria rosea, n = 1%, Granulicatella elegans, n = 1%, and Alicyclobacillus acidocaldarius, n = 1%), two Gram-negative bacteria (Klebsiella pneumoniae, n = 15%) and Pseudomonas aeruginosa (n = 2%), one yeast (Candida albicans, n = 15%), and five filamentous fungi were isolated from patients with oral cavity infections. Conclusion: Consequently, the most common bacteria identified from the clinical materials taken from patients exhibiting signs of oral cavity infections were Streptococcus mutants, Staphylococcus aureus, Klebsiella pneumoniae, and Candida albicans. | ||
