REVIEW OF RELATED LITERATURE This investigatory project aims to make use of rambutan peeling extracts that is high in phenolic compounds such as tannin and saponin that exhibits antioxidant activity and antibacterial activity against pathogenic bacteria. Although the seeds contain such compounds the peeling exhibit greater amount of the said compounds. Rambutan is a very popular fruit cultivated in the Philippines and it is eaten in large amounts. The rambutans rind is quickly discarded and

Whooping Cough A. Name the bacteria that cause this childhood disease. What is its morphology? bacillus bordetella pertussis. B. pertussis is an extremely small‚ strictly aerobic‚ Gram negative‚ cocobacillus short rod. What does “Wooping Cough” mean? Pertussis is a highly contagious bacterial disease that causes uncontrollable‚ violent coughing. The coughing can make it hard to breathe. A deep "whooping" sound is often heard when the patient tries to take a breath. Describe in detail the

Bartonella henselae is the bacterium that causes cat scratch disease Bartonella henselae is a small gram negative- bacillus. It is an aerobic organism ~1µm in length and ~ 0.5 µm in diameter‚ that occasionally takes a slightly curved shape. It makes small jerking movements in the fresh state‚ but has no whips.1 Optimal growing conditions are blood (5%)‚ moist atmosphere

It is a common cause of antibiotic-associated diarrhea (AAD). It accounts for 15-25% of all episodes of AAD.” [1] The two toxins produced by C. diff are toxin A and toxin B. “Toxin A is

This study intends to examine: The bacteria population of samples obtained from several site across south east coast of England. Identify species of Gram Negative (-) & (+) of each sample. identify any faecal coliform bacteria which might suggest water contamination. These indicator organisms are used for indication of water contaminant by human and other warm-blooded animals (APHA 1992). Several

Way‚ Tehran‚ Iran Correspondence: * rasooli@shahed.ac.ir ABSTRACT Preservative agents are required to ensure that manufactured foods remain safe and unspoiled. Antimicrobial properties of essential oils (EOs) reveal that Gram-positive bacteria are more vulnerable than Gram-negative bacteria. A number of EO components have been identified as effective antibacterials‚ e.g. carvacrol‚ thymol‚ eugenol‚ cinnamaldehyde and cinnamic acid‚ having minimum inhibitory concentrations (MICs) at higher dilutions

appearance was observed and recorded. There was growth that appeared pinkish in color. The first test we did was basic stain using a heat fixed emulsion which kills the bacteria and allows them to adhere to the slide and thickens their protein for better staining. I then covered the heat fixed emulsion with crystal violet for one minute. The stain was then rinsed with distilled water. The stain was then pat dry with bibulous paper then observed under oil immersion to determine morphology. Upon completion
