Microbial endocrinology is a relatively new research area that already encompasses the anaerobes. Stress hormones, epinephrine and norepinephrine, can affect the growth of anaerobic bacteria such as Fusobacterium nucleatum, Prevotella spp., Porhyromonas spp., Tanerella forsythia and Propionibacterium acnes and can increase virulence gene expression, iron acquisition and many virulence factors of some...
This review focuses on the virulence arsenal of the most pathogenic species among Gram positive anaerobic cocci, Finegoldia magna according to recently published data from 2012 to 2016. Virulence factors like sortase dependent pili and F. magna adhesion factor (FAF) facilitate the start of the infection. Albumin binding protein (PAB) enhances F. magna survival. FAF, subtilisin-like extracellular serine...
Evolution of antibiotic resistance in the anaerobes was reviewed using recent data covering 2000–2013 as compared to previous years. All studies reported growing moxifloxacin resistance in Bacteroides/Parabacteroides spp. in Europe and USA and in Clostridium difficile in Europe. In half or more studies, the resistance rates in Bacteroides/Parabacteroides spp. to amoxicillin–clavulanate or ampicillin–sulbactam...
The aim was to evaluate the effect of 30% ethanolic extract of Bulgarian propolis on 94 clinical anaerobic strains. The strains were tested by both agar-well diffusion (wells, 7mm diameter) and disk-diffusion methods. Only 15% of Clostridium-, 3.3% of other Gram-positive- and 9.1% of Gram-negative anaerobic strains were not inhibited by 30μL propolis extract per well. Propolis extract was more active...
The aim of the study was to evaluate the incidence of anaerobic bacteria in 198 patients with pleural empyema and the susceptibility of isolates to eight antibacterial agents. Isolates were identified by the Crystal anaerobes identification system, API System rapid ID 32 A and/or routine methods. Susceptibility was tested by Sceptor MIC system for anaerobic bacteria and limited agar dilution method...
