Enterobacter

such as Haemophilus influenzae, Neisseria, in addition to Actinomycetes and Fusobacteria. Resistance to bacitracin is extremely uncommon. Meanwhile, neomycin acts on both gram-positive and gram-negative pathogens including staphylococci, Proteus, Enterobacter aerogenes, Klebsiella pneumoniae, Salmonellae, shigallae, Haemophilus influenza, Pasteuerella, Neisseria meningitides, Vibro cholera, Bordetella pertussis, Bacillus anthracis, Corynebacterium diptheriae, Streptococcus faecalis, Listeria…

bacterial isolates and their frequency of isolation from dumpsites were Escherichia coli (33.3%), Klebsiella spp.(16.7%) ,Pseudomonas spp. (13.3%), Proteus spp.(10%), Streptococcus spp. (8.3%), Salmonella spp. (6.7%), Staphylococcus aureus (6.7%) and Enterobacter spp. (5.0%). The high presence of pathogenic bacteria from dumpsites is of serious public health concern and highly significant. Antibiotic susceptibility testing using the disc diffusion…

In order to determine the identity of two unknown bacteria, I performed a series of experiments over several days. To begin this process I created a dichotomous key that I utilized as a guide to perform a series of inoculations, while using both selective, and differential media. The series of inoculations eliminated bacterium based on test results until the correct bacteria were both positively identified. On day one of this process I received two bacteria, one labeled 7A and the other…

Surjawidjaja et al. (2003) showed that Zn-sulfate at concentrations between 1.2 and 1.8 mg/ml inhibited the growth in enteric pathogens commonly associated with diarrheal disease (Salmonella typhi, Salmonella groups A, B, C, D and E, Escherichia coli, Enterobacter, Shigella and Vibrio cholera). Our results seem to indicate that Giardia is more sensitive to Zn than these enteric…

RESULTS AND DISCUSSION Particle size analysis The diameters of the curcumin, honey and curcumin+WPI+MH complex measured using Mastersizer were 3.480 µm, 1.349 µm and 20.911 µm respectively. The size of WPI measured with Zetasizer was 250 nm. Quantitative particle size and shape analysis provides information that has either a direct effect or correlation to issues such as bioavailability, solubility, formulation stability, and quality control. Scanning Electron Microscopy SEM micrographs of…

that to the unknown bacteria data table it showed that both the shapes and arrangements match. That helped me to narrow it down drastically since it was the only one that was shaped like the way it was. My biochemical tests matched perfectly with Enterobacter aerogenes. One huge experimental error I made was not doing the gram staining correct the first time but I tried to fix it. I had to redo my nutrient agar plates twice because the first time it seemed like there was only one microbe. It was…

Following Gram staining and microscopic examination, Unknown 15 was identified to be a Gram positive coccoid. Based on these results, all of the Gram negative genera were eliminated including: Enterobacter, Citrobacter, Klebsiella, Escherichia, Pseudomonas, Serratia, Alcaligenes, Neisseria, Proteus, Salmonella, Shigella, Erwinia, Veillonella, and Flavobacterium (5). Bacillus, Lactobacillus, Listeria, Kurthia, and Arthrobacter were eliminated because they did not match the coccoid shape of…

Sara Parks Unknown Report Introduction One of the many reasons to study microbiology is to gain a better understanding of microorganisms and the huge part they play in the world. It is imperative to know the differences between microorganisms. This knowledge is useful in many cases; for instance, a patient with an unidentified infection could be administered effective treatment if one possessed the knowledge to correctly define the microorganism. Furthermore, the purpose of this unknown…

The purpose of performing physiological tests is to figure out certain characteristics of microorganisms or to reach a conclusion on what an unknown microorganism is. It can be also used to determine what is needed for bacteria to be cultured in or on certain media. Culture media can either be liquid or solid, and they can be used to identify certain characteristics of different bacterial species. This is indicated by the growth or lack of growth in or on certain media. Solid media can also be…

An unknown sample #18 was obtained on November 6, 2017. The sample came in a glass test tube with a cotton swab that contain the unknown sample. To find the identity of the unknown sample, we had to conduct several biochemical tests to eliminate and narrow down possible organisms that fit the biochemical description to accurately identify our unknown organism of interest. These biochemical tests provided insight on the physical color retention of our unknown sample, and through’s the unknown…
