One afternoon I was walking home from my friend’s house along the railroad tracks barefoot and suddenly I felt a sharp prickly pain shooting up my leg‚ I look down and realized I had stepped on a broken piece of glass. When I got home my mother told me I should go get a tetanus immunization in case I had contracted tetanus. I did not know what tetanus is‚ so then I decided to do some research. Tetanus‚ also more commonly known as Lockjaw‚ is caused by Clostridium tetani. Lockjaw can occur as a bacterial

Abstract In an environment isolation procedure‚ experiments under categories‚ such as‚ morphology‚ physiology‚ antibacterial susceptibility‚ selective media‚ and biochemical provide results. Both the unknown isolate and members of the Micrococcus genus were shown to be obligate aerobes. By using staining methods‚ this proved that the organism is gram positive. Morphology‚ such as‚ orange pigmentation and coccus shape provide similarities to the Micrococcus genus. Physiological tests were shown to

cytochrome oxidase test on both organisms; again‚ organism A was oxidase positive while organism B was oxidase negative. Then I decided I would run the biochemical tests on organism B. I observed that organism B was non-motile and did not produce endospores. With these results‚ I narrowed down the possible species to Enterococcus faecalis‚ Enterococcus faecium‚ Lactococcus lactis‚ Leuconostoc mesenteroides‚ Pediococcus parvulus‚ and Streptococcus mitis.

Primarily‚ the Archaea were once believed to be just another rare group of bacteria‚ because like bacteria‚ they are single-celled microscopic prokaryotic organisms with no membrane bound nucleus (http://www.fossilmuseum.net/Evolution/archaeaevolution.htm). Despite the similarities in the cell structure of Eubacteria and Achaea‚ molecular research by Dr Carl Woese and his co-workers indicated that they differ significantly on the molecular level (Bacteria in Biology‚ Biotechnology and medicine‚ Paul

Kingdom Monera Nerissa Mae F. Dadores MONERANS * Oldest and most abundant organisms. * Unicellular organisms without a nucleus. * Prokaryotes are single-celled organisms. They are the smallest‚ simplest organisms. * Microscopic & Undergoes Asexual reproduction. HISTORY The taxon Monera was first proposed as a phylum by Ernst Haeckel in 1866. Subsequently‚ the taxon was raised to the rank of kingdom in 1925 by Édouard Chatton. The last commonly accepted mega-classification

HOW DO THEY AFFECT HUMANS AND WHY DO WE CARE? Chlamydia is the most common sexually transmitted disease in the world. It is estimated that there were 92‚000‚000 new cases reported in 2009. The 3 strains of c. Trachamotis are trachoma which affects the eyes‚ urethritis which affects the urethra and cervix

The spot inoculation method was followed for antifungal activity of bacterial strain Paenibacillus elgii TS33 25. The nutrient agar medium was prepared‚ sterilized at 121ºC‚ poured into the sterilized peteriplates and allowed to solidify under aseptic conditions. After solidification bacterial strain Paenibacillus elgii TS33 was spot inoculated on nutrient agar medium and incubated at 37ºC for 48 hours. After incubation the molten potato dextrose agar medium containing the spores of test fungus‚
