materials and methods the subjects included 27 male and 3 female patients with advanced chronic periodontitis. the mean age of the patients was 47.6 ± 2.0 years old. p. gingivalis was isolated from the samples and identified by various diagnostic tests, including gram staining, indol test, and fluorescent test. minimum inhibitory concentration (mic) of the essential oil against isolated p. ging...

Broth microdilution tests and an antimicrobial interaction (synergy) studies using various combinations of cefoperazone and sulbactam were performed in an effort to determine the most appropriate in vitro dilution test system. The test results with cefoperazone and sulbactam were categorized as synergistic (complete or partial) for nearly 80% of the strains isolated from clinical trial patients...

Thirty isolates of the yeast form of Sporothrix schenckii were evaluated for in vitro susceptibility to itraconazole and terbinafine by the recommended NCCLS modified technique (M27-A2). The MICs of itraconazole obtained oscillated between 0.062 and 4.0 microg/ml, and those of terbinafine oscillated between 0.007 and 0.50 microg/ml; therefore, terbinafine showed greater in vitro activity.

During recent decades, antifungal susceptibility testing has become standardized and nowadays has the same role of the antibacterial susceptibility testing in microbiology laboratories. American and European standards have been developed, as well as equivalent commercial systems which are more appropriate for clinical laboratories. The detection of resistant strains by means of these systems ha...

Macrolides are currently used to treat Streptococcus pyogenes infections where allergy or resistance prevents the use of penicillin. However, growing macrolide resistance is now seen worldwide, with rates of 5%-40% being reported. In this context it is therefore important to have other therapeutic options. The aim of this study was to ascertain the potential role of moxifloxacin, a third-genera...

Pathogenic fungi are the cause of life-threatening infections in an increasing number of immunocompromised patients. The intrinsic resistance to antifungal therapy observed in some genera, along with the development of resistance during treatment in others, is becoming a major problem in the management of these diseases. We reviewed the epidemiology of the most common systemic fungal infections...

Laparoscopic gastric banding is a common bariatric procedure worldwide. Rapidly growing mycobacteria are environmental organisms increasingly seen as pathogens,often in infected prosthetic material. We report 18 cases of infection associated with laparoscopic gastric banding caused by Mycobacterium fortuitum and M. abscessus in Australia during 2005–2011. We identified cases by reviewing positi...
