Mwambete found that the plant may be useful for combating Escherichia coli‚ the common yeast Candida albicans‚ Salmonella typhi and Staphylococcus aureus. It may be useful against Klebsiella pneumoniae as well‚ Mwambete notes. Klebsiella pneumoniae is frequently a hospital-acquired pathogen. It causes pneumonia‚ urinary tract infections and intraabdominal infections‚ according to the Centers

The point of this report is to further explore the identification of my unknown bacteria by revealing the results of the experiments and comparing them to the other six known bacteria: Micrococcus luteus‚ Staphylococcus aureus‚ Staphylococcus epidermidis‚ Alcaligenes faecalis‚ Escherichia coli‚ and Proteus vulgaris that were used in the lab‚ as well as comparing and contrasting the actual and factual results.

This lab was conducted in order to understand basic differences among differential and selective media‚ while recognizing how each media is used to isolate and identify microorganisms (Wistreich‚ 2003). The first microorganism analyzed was Staphylococcus epidermidis. This organism is gram-positive‚ single celled‚ arranged in grape-like clusters‚ and cocci in shape (Bukhari‚ 2004). S. epidermidis is approximately 0.5 to 1.5 micrometers in diameter‚ it is a facultative anaerobe but grows best

Several species of Staphylococcus are found on the skin‚ intestines‚ nasal passages‚ etc. of warm-blooded animals. Some species of Staphylococcus‚ particularly Staphylococcus aureus can be pathogenic are capable of causing illness. Pseudomonas aeruginosa is widely distributed in soil‚ water and plants. It

Other problems associated with regulatory pressures are also demonstrated by the fact that Medicare is planning to no longer reimburse for hospital-acquired infections– particularly Methicillin Resistant Staphylococcus aureus (MRSA).

Contracting may occur through coughing or sneezing with airborne illness (known as “droplet spread”)‚ or through

This principle later lead to medicines that could kill certain types of disease-causing bacteria inside the body. At

Mutation rates are usually very low but there are factors that can increase the mutation rates. These factors are referred to as mutagens and conclude a range of physic-chemical agents. UV light is a mutagen that affects all living things and has an adverse effect on the

As discussed earlier‚ the extraction of the turmeric powder was done using various solvents at different temperatures. Different solvents provided extracts with different colour values at varying temperatures. At 50⁰C‚ the maximum colour value was found to be in the extract obtained using ethanol as the solvent.

In our experiment‚ we concluded that Bacillus cereus from soil can hydrolyze starch in order to use these starches as a carbon source and use it. But Staphylococcus cannot.
