Actinomyces spp. are located without displaying any pathogenic effect in the oral flora. However, the disruption of oral microenvironmental balance, mucosal tissue integrity, and defense system can cause microorganisms to settle on deep periodontal tissues and to induce pathologic reactions. The present case report describes erythematous and desquamative lesions with pseudomembrane limited to t...

The resident microbial flora in the oral cavity typically contains 10 bacteria (Mims et al., 2005). However, only 150 microbial species have been isolated and cultured from root canals. The endodontium is a sterile cavity and the invasion of oral microbes to establish infection is by the penetration to enamel and dentine and overcome the host responses (Bergenholtz, 1974). Although all the bact...

Even though the oral microbiome is one of the most complex sites on the body it is an excellent model for narrow-spectrum antimicrobial therapy. Current research indicates that disruption of the microbiome leads to a dysbiotic environment allowing for the overgrowth of pathogenic species and the onset of oral diseases. The gram-negative colonizer, Porphyromonas gingivalis has long been consider...

The global distribution of individual species of oral bacteria demonstrates their ability to survive among their human hosts. Such an ubiquitous existence is the result of efficient transmission of strains and their persistence in the oral environment. Genetic analysis has identified specific clones of pathogenic bacteria causing infection. Presumably, these express virulence-associated charact...

Probiotics are dietary supplements containing potentially beneficial bacteria or yeasts. They are administered in different quantities that allow for colon colonization. These products help in stimulating health by promoting flora and also suppressing the pathologic colonization and disease spread. Initially, probiotics were used for the management of intestinal tract problems. But, nowadays it...

Background: Tinea versicolor is a superficial fungal infection caused by normal skin flora and treatable by topical and oral anti-fungal medications. Objective: To evaluate the clinical and paraclinical response and to compare possible side-effects of a single oral dose of fluconazole and ketoconazole in treatment of tinea versicolor. Patients and Methods: In this clinical trial, sixty-si...

Disruption of the oral mucosal lining and the lack of normal defense mechanisms predispose bone marrow transplant (BMT) patients to life-threatening infections, often caused by oral flora. Chlorhexidine, used as an oral antiseptic, appears promising in limiting oral bacteria and fungi, and therefore, may decrease oral complications associated with BMT. The purpose of this study was to determine...

Background and Aim: The aim of this study was to conduct in vitro and in vivo studies for the evaluation of antimicrobial potential of four Nigerian indigenous chewing sticks and to compare the oral effects of the popular Nigerian chewing sticks with toothpastes and other teeth-cleansing agents on a total of 21 and 17 oral bacterial strains isolated from children and adult dental caries respect...

Patients with a short small bowel (SSB) suffer continuously from abdominal pain, flatulence and diarrhoea. Their faeces contains a very characteristic flora, that normally consists of /70% (sometimes even up to 99%) of lactobacilli. In this study, we intended to prove that the mentioned inconveniences are mainly caused by fermentative activity of the massively present heterolactic lactobacilli....
