BACKGROUND Periodontitis is inflammation of the periodontium and causes destruction of the connective tissue attachment of the teeth and alveolar bone. Porphyromonas gingivalis is the primary pathogen for the destructive periodontal diseases. The aim of the study is to evaluate the efficacy of probiotic on P. gingivalis. MATERIALS AND METHODS An in vitro study was done to analyze the effectiv...

The antimicrobial property of volatile aromatic oils from medicinal as well as other edible plants has been recognized since antiquity. Candida species are an important cause of opportunistic infections in the oral cavity of immunocompromised patients and vaginal candidiasis. The antifungal activity of the essential oil of Cinnamomum cassia (cassia oil) was investigated against 75 clinical isol...

Inoculum size and incubation time were varied during broth microdilution testing of the susceptibilities of 35 strains of lactic acid bacteria to six antibiotics. An increase in either parameter resulted in elevated MICs for all species. An inoculum of 3 x 10(5) CFU/ml is recommended to assess the antibiotic susceptibilities of these bacteria by using broth microdilution.

With the increase in invasive fungal infections due to Candida species and resistance to antifungal therapy, in vitro antifungal susceptibility testing is becoming an important part of clinical microbiology laboratories. Along with broth microdilution and disk diffusion method, various commercial methods are being increasingly used for antifungal susceptibility testing, especially in the develo...

The in vitro susceptibilities of 90 clinical isolates of gram-positive and gram-negative aerobic bacteria to six cationic peptides, buforin II, cecropin P1, indolicidin, magainin II, nisin, and ranalexin, were evaluated by two broth microdilution methods. The first method was performed according to the procedures outlined by the National Committee for Clinical Laboratory Standards for bacteria ...

In our study, it was aimed to investigate the antimicrobial effect of 6 plant extracts obtained with methanol by using maceration and soxlet methods from 3 species Nigellla sativa (Black seed), Cuminum cuminum (cumin) Pimpinella anisum (anise) grown in Kırıkkale province liquid microdilution method against Staphylococcus aureus (ATCC 25923) Escherichia coli 25922). All (black cumin), (Cuminum) ...

Laboratory assessment of antimicrobial susceptibility is a prerequisite for adequate management of infections. The aim of this research was to evaluate the performance of the novel FASTinov® kit for antimicrobial susceptibility testing (AST) of Gram negative bacilli directly on positive blood cultures. One hundred and two positive blood cultures from patients of a Portuguese University Hospital...
