A simple and convenient method for culturing anaerobic bacteria is described. Cultures can be grown in commercially available flasks normally used for preparation of sterile external solutions. A special disposable rubber flask closure maintains anaerobic conditions in the flask after autoclaving. Growth of a variety of anaerobic oral bacteria was comparable to that obtained after anaerobic inc...
Although the bacterial flora of the conjunctiva in children and adults has been studied, there has been no previous comparison between these two age groups of anaerobic as well as aerobic bacteria. Conjunctival cultures from 229 eyes of 144 uninfected subjects were analysed for aerobic, microaerophilic, and anaerobic bacteria. Adults showed a greater number of species per eye than did younger s...
Anaerobic bacteria have been identified in abundance in the airways of cystic fibrosis (CF) subjects. The impact their presence and abundance has on lung function and inflammation is unclear. The aim of this study was to investigate the relationship between the colony count of aerobic and anaerobic bacteria, lung clearance index (LCI), spirometry and C-Reactive Protein (CRP) in patients with CF...
Clostridium thermocellum DSM1313 is a thermophilic, anaerobic bacterium with some of the highest rates of cellulose hydrolysis reported. The complete genome sequence reveals a suite of carbohydrate-active enzymes and demonstrates a level of diversity at the species level distinguishing it from the type strain ATCC 27405.
Clinafloxacin was more active than ciprofloxacin against 4,213 aerobic and facultative anaerobic bacterial isolates from 10 medical centers, as tested by broth microdilution and disk diffusion methods. The percentage of 201 anaerobes susceptible to clinafloxacin by broth microdilution was comparable to cefoxitin. Our data support the proposed disk diffusion interpretive criteria for aerobic bac...
Anaerobic and aerobic bacteria were often found as mixed infections in 225 lethally irradiated mice. Of a total of 57 mice that were sacrificed, aerobic bacteria were recovered exclusively in 9 (27%) of the 34 culture-positive mice, anaerobic bacteria were recovered exclusively in 15 (44%), and mixed aerobic and anaerobic flora were recovered in 10 (29%). The predominant organisms were anaerobi...
AIM/BACKGROUND Thymoquinone (TQ) is the major active principle of Nigella sativa seed (black seed) and is known to control many fungi, bacteria, and some viruses. However, the activity of TQ against anaerobic bacteria is not well demonstrated. Anaerobic bacteria can cause severe infections, including diarrhea, aspiration pneumonia, and brain abscess, particularly in immunodeficient individuals....
A broth-dilution method for performing antimicrobial susceptibility tests on anaerobic bacteria has been proposed. The medium used in the test was Schaedler broth, with incubation in a glove box with an atmosphere of 5% CO(2), 10% H(2), and 85% N(2), or in the GasPak system. Minimal inhibitory concentrations for selected antibiotics were determined, under these conditions, by using a convention...
The isolation of anaerobic bacteria from routine wound swabs by three procedures was evaluated. Recovery of anaerobic organisms was doubled by immediate incubation of seeded plates, and the recovery could be further dramatically improved by the use of prereduced media, in conjunction with an anaerobic chamber. Recommendations for the treatment of swabs and cultures for anaerobic investigation a...
A bottle plate for the cultivation of methanogens or other organisms in a defined pressurized-gas atmosphere was developed. The bottle provides the convenience of an agar streak plate, solves the problem of the water exudate from agar medium, and provides a convenient way of adding or sampling a defined gas atmosphere.
