Antibacterial activity of allopathic medicine versus phytomedicine against Enterococcus faecalis: An in-vitro study. Abstract Background: A successful endodontic treatment depends on appropriate instrumentation‚ irrigation‚ decontamination and obturation. Decontamination of root canal plays a crucial role in the success of endodontic treatment. Therefore‚ a suitable medicament is essential which can effectively eliminate bacterial contamination. Aim and objectives: To investigate and compare the

Live in both fresh water and marine habitats. Some are found in soil‚ and many have adapted to parasitic life on the body of marine animals or internal organs of both aquatic and terrestrial animals. Amoeba reproduces asexually by binary and multiple fissions. They eat algae‚ bacteria‚ other

sociological groups by employing interpretive and naturalistic approaches. It is both observational and narrative in nature and relies less on the experimental elements normally associated with scientific research (reliability‚ validity and generalizability). Agar (1980) suggests that qualitative inquiry relies more on appearance‚ verisimilitude and transferability. On the other hand‚ Bosk (2001) emphasizes the importance of credibility‚ transferability‚ dependability and conformability in qualitative studies

Obtain agar plates from your instructor and label them as in the figure 1 provided below. 2. Using a sterile pipet‚ remove 130µL mixed bacterial suspension from the tube “C “‚ remove the lid from the control plate and dispense the bacteria unto the agar. Use a cell spreader to spread the bacteria evenly onto the agar surface. Use of the cell spreader; Dip the cell spreader into ethanol. Pass the spreader

Floyd and Dr. Kennedy (1) unless otherwise noted. The first step that was used was a three streak method‚ described in Lab 4‚ on a Blood Heart Infused/Trypticase Soy Agar plate to isolate the two unknown bacteria. Once the two bacteria were incubated‚ grown‚ and isolated they were each individually streaked on a Trypticase Soy Agar plate to isolate individual colonies to be studied‚ tested and identified. After incubation of the individual TSA plates‚ the morphologies were viewed and noted and

quantitative Ames test is similar to the spot-overlay Ames test‚ except that the mutant Salmonella tymphimuium (which cannot composite histidine) is treated with various concentrations of the mutagen Diet Coke to view which sections of the Davis Minimal Agar Plate form colonies (Bjeldanes‚ et al. 1982). Mutagenicity has been known to be carcinogenic and that can cause a toxicological effect that presents a potential health risk for humans ( Resende‚ et al. 2012).

Secondly‚ the second slant will become a stock culture to prevent the shortage of slants during performing the series of tests. Kliger’s Iron Agar tests can be used to determine multiple characteristics of unknown microorganism #17. Kliger’s Iron Agar slants also contains a pH indicator‚ phenol red‚ which can be used to test the presence of fermentation. If there is a

Went’s experiment but the agar block was placed on one side of the plant and not in the middle. This caused the plant to grow curved. This is because the auxin went all to one side causing it to grow. One side growing faster then another causes the plant to bend. Gravity can cause an unequal amount of auxin. When a tip of a coleoptile is put on an agar block evenly both side of the block will get equal amounts of auxin but if you were to tip the 90 degrees one side of the agar block would receive more

The unusual members of NFGNB represent a challenge for the routine clinical microbiological laboratories‚ owing to their complex identification along with their unpredictable antimicrobial susceptibility patterns 14. The isolation rate of NFGNB (18.7%) recorded in our study comes in agreement with a previous Indian study carried out in a tertiary care hospital‚ where it was 16.18% 15. Whereas‚ it comes higher the result recorded in another Indian tertiary care hospital where it was 9.32% 16. The
