Antibacterial action of the irrigants against Enterococcus faecalis in the root canal The overall percentage reduction of E. faecalis inside the root canal after biomechanical procedures was presented in table1. All the irrigants significantly reduced bacteria in comparison with positive control group (P< 0.01). The average reduction of bacteria in the presence of E.galbie did not have any significant difference with 2.5% NaOCl‚ CHX 2%‚ CHX 0.2% and M.communis L. (P > 0.05). The average reduction

then flooded the plate with Iodine and were able to observe and record starch Hydrolysis. (Table 1) * In order to test carbohydrate catabolism under anaerobic conditions we tested cultures of Pseudomonas aerugenosa‚ Escherichia coli‚ and Alcaligenes faecalis in tubes containing a glucose medium. After inoculating each tube with each of the bacteria 5mm of mineral oil was poured into one of the tubes containing bacteria to observe anaerobic respiration and while one remained without mineral oil

negative organisms were positive for glucose except for two. Since our organism tested negative for glucose it helped narrow it down to only those two organisms‚ Alcaligenes faecalis and Pseudomonas aeruginosa. The other tests that we performed on our unknown were not really helpful when it came to determining if it was Alcaligenes faecalis or Pseudomonas aeruginosa because they both had all the same characteristics when it came to the lactose‚ mannitol‚ motility‚ indole‚ citrate‚ H2S‚ urease‚ methyl

Microbiology Laboratory Report Identification of Unknown Bacteria 03/10/05- 04/01/05 Authors: Richard Hendricks‚ Jessica Prebish; NMU Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques

Screening and identification of rhizobacteria isolated from heavy metal contaminated soils INTRODUCTION As a result of human activities such as mining‚ agriculture and industrial activity‚ heavy metal pollution has become one of the most serious environmental problems today. Elevated levels of heavy metals not only decrease soil microbial activity and crop production‚ but also threaten human health through the food chain. Soil microorganisms can degrade organic contaminants‚ while metals need

acidophiles (acid-loving)‚ neutrophiles (neutral ph range)‚ or alkaliphiles (alkali-loving). The one that causes disease in humans would be the neutrophiles‚ which have an ideal pH range of 5.4 to 8.0. There are exceptions‚ however‚ like Alcaligenes faecalis and Vibrio choleae‚ which are both alkaliphiles and can infect humans. Bacteria can also be classified as to the temperature range in which it grows best. Psychrophiles are cold-loving and can live in temperatures from 0 20 C. Mesophiles

Pure Culture Techniques In this first lab‚ you will be learning some very fundamental and important techniques. As is the case with most things‚ shorts cuts usually get you in trouble. This is especially true in Microbiology. The techniques you will be learning tonight‚ if mastered correctly‚ will make your life and learning experience in Microbiology much easier‚ if you don’t pay attention and practice these techniques incorrectly‚ well then……? Today you will be learning the following techniques:

physicochemical test readings showed significant fluctuations in different points indicating radically heterogeneous conditions throughout the distribution system. The total count varied from 1.2x102 to 6.3x103 cfu/ml. Different bacterial genera including Alcaligenes spp.‚ Bacillus spp.‚ Corynebacterium spp.‚ Escherichia spp.‚ Micrococcus spp.‚ Pseudomonas spp.‚ Shigella spp.‚ Staphylococcus spp. and Streptococcus spp. were isolated from the collected samples. The bacterial community was found to be diversified
