Abstract The purpose of this experiment was to study the transfer of genetic information on plasmid Fâlac by using Escherichia coli. Plasmid transfer was measured by using two different methods. The first one was by using selection and contraselection with three antibiotics: streptomycin(which was replaced by naladixic acid for the second part of the experiment), […]
Analysis & Discussion The primary objective of this investigation was to test ultraviolet radiation as an alternative disinfectant for Acanthamoeba in its more resistant cyst form. A previous study had already shown that multipurpose solutions were ineffective compared to hydrogen peroxide based systems at eliminating Acanthamoeba trophozoite contaminations. 5 This was a follow-up to that […]
The HIV/AIDS Epidemic In South Africa Acquired Immune Deficiency Syndrome (AIDS) caused by the Human Immunodeficiency Virus (HIV) is one of many infectious diseases that plague the world today.

The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases – enzymes which break down agarose into oligosaccharides. This physiological class branches through genii, regardless of Gram Stain status or […]

Antigen recognition allows the immune system to recognize each antigen with tremendous specificity in order to avoid an immune response to host tissues. One way in which the immune system accomplishes this is through the production of antibodies by the B-cell. Each antibody must be able to bind specifically to one part of an antigen; […]
In 1884, Arthur Nicolaier isolated the strychnine-like toxin of tetanus from free-living, anaerobic soil bacteria. The etiology of the disease was further elucidated in 1884 by Antonio Carle and Giorgio Rattone, who demonstrated the transmissibility of tetanus for the first time. They produced tetanus in rabbits by injecting their sciatic nerve with pus from a […]
