Research Report 1: What are the differences between bacterial‚ viral fungal and parasitic infections? How is each treated? A bacteria is a living cell organism that can survive inside our body and other non living objects as well. There are both good and bad bacterias and the good bacteria is known to helps fight against the bad bacteria that makes it’s way into our bodies. According to a www.righthealth.com‚ less then 1% of bacteria is actually harmful to us. In fact‚ we couldn’t survive

Investigation of the probiotic properties of bacterial strains from two probiotic drinks and their survivability in artificial gastric juice ABSTRACT: Two probiotic drinks were investigated in vitro to test their ability to survive acidic conditions and their probiotic factors. Both the products: Actimel and Yakult contain gram-positive bacteria‚ but Actimel also has a gram-negative bacteria. The ability to survive was investigated by adding artificial gastric juice to the products and incubating

Abstract In vitro studies show that tea tree oil can be used as a topical methicillin-resistant Staphylococcus aureus (MRSA) eradication regimen in a laboratory setting. This report has been researched using a wide range of journals and internet sources to find out whether tea tree oil can be used as an alternative to Mupirocin for those suffering from MRSA colonisation. The journals that were searched contained useful information about tea tree oil as an antiseptic‚ however‚ many of the studies

1. Introduction Since the discovery of plasmid‚ various methods have been developed to isolate plasmid DNA. All the methods have one common and important target of isolating plasmid DNA of high quality and quantity in less time. These methods are not completely safe because of use of toxic chemicals compounds. The developed protocol for plasmid extraction is based on the alkaline lysis method of plasmid preparation (extraction at pH 8.0) with slight modifications. Cell lysis reagent sodium dodecyl

bacteria and archaea are enclosed in cell membranes. Archaea have a single cell membrane that absences a peptidoglycan wall and also their genetic transcription and translation‚ the two main processes in molecular biology do not show the typical bacterial features‚ but are quite similar to those of eukaryotes. Archaea are more related to eukaryotes‚ even though eubacteria and archaea are prokaryotic groups. Bacteria were the first forms of life that appeared on earth. Bacteria and archaea dominated

lineage. The earliest eukaryotes and the bacterial ancestors from which they arose are assumed to have lacked sex. For instance‚ some bacteria use conjugation to transfer genetic material between cells; and while not the same as sexual reproduction‚ this also results in the mixture of genetic traits. The reason that bacterial conjugation is not the same as sexual reproduction is that the numerous genes necessary for conjugation are not located on the bacterial chromosome‚ but on small circular DNA self-replicating

Transformation occurs naturally in some species of bacteria‚ but it can also be affected by artificial means in other cells. Conjugation: The process whereby two ciliates come together in a temporary fusion to exchange micro nuclear material‚ then separate‚ each being a fertilized cell. Explain how the F plasmid controls conjugation in bacteria. In bacterial conjugation the host bacterium attaches to another bacterium via pili. The plasmid region contains its own origin of replication in other
