Presence of Staphylococcus spp. and Candida spp. in the human oral cavity BJM
Martins,Clélia Aparecida de Paiva; Koga-Ito,Cristiane Yumi; Jorge,Antonio Olavo Cardoso.
The presence of yeasts and staphylococci in the oral cavity is important because they can act as supplementary microbiota and in certain situations can cause oral or systemic diseases. The aim of this work was to study the prevalence of Candida spp. and Staphylococcus spp. in the human oral cavity. Oral rinses were collected from sixty-eight individuals according to the technique described by Samaranayake and MacFarlane and then cultured on Sabouraud medium supplemented with chloramphenicol and Baird-Parker agar. After the incubation period, the microorganisms were isolated and identified through biochemical tests. The data obtained were statistically analysed by ANOVA. Candida spp. were isolated from 61.76% of the examined individuals and C. albicans was...

Staphylococcus spp. in the oral cavity and periodontal pockets of chronic periodontitis patients BJM
Loberto,Jussara Cia S.; Martins,Clélia Ap. de Paiva; Santos,Silvana S. Ferreira dos; Cortelli,José Roberto; Jorge,Antonio Olavo Cardoso.
Staphylococcus spp are not usually isolated from the oral cavity, and when this occurs, they are considered to belong to the transitory microbiota. Individuals with periodontal disease represent possible reservoirs of these opportunistic bacteria in the oral cavity. The use of antibiotics for treatment of periodontal disease or other infections may predispose to the increase of the number of Staphylococcus spp. in the oral cavity. These microorganisms easily become resistant to antibiotics, and may result in superinfection. The purpose of this study was to evaluate the presence of Staphylococcus spp. in the oral cavity and in periodontal pockets of patients with chronic periodontitis, identify the isolates and verify the relationship between the presence...

Opportunistic microorganisms in patients undergoing antibiotic therapy for pulmonary tuberculosis BJM
Querido,Silvia Maria Rodrigues; Back-Brito,Graziella Nuernberg; Santos,Silvana Soléo Ferreira dos; Leão,Mariella Vieira Pereira; Koga-Ito,Cristiane Yumi; Jorge,Antonio Olavo Cardoso.
Antimicrobial therapy may cause changes in the resident oral microbiota, with the increase of opportunistic pathogens. The aim of this study was to compare the prevalence of Candida, Staphylococcus, Pseudomonas and Enterobacteriaceae in the oral cavity of fifty patients undergoing antibiotic therapy for pulmonary tuberculosis and systemically healthy controls. Oral rinsing and subgingival samples were obtained, plated in Sabouraud dextrose agar with chloramphenicol, mannitol agar and MacConkey agar, and incubated for 48 h at 37ºC. Candida spp. and coagulase-positive staphylococci were identified by phenotypic tests, C. dubliniensis, by multiplex PCR, and coagulase-negative staphylococci, Enterobacteriaceae and Pseudomonas spp., by the API systems. The...
