    Description: Hi! My name is Caulobacter crescentus. I am a single celled, Gram-, rod-like, prokaryotic cell. I can be flagellated in a polar structure or i can have a stalk. I use oxygen as my final electron acceptor therefore I go through aerobic respiration. If you want to visit me you can find me in low-nutrient aquatic environments, such as lakes. I have a virulence factor called MviN. I, Caulobacter crescentus, am also positively effective with the process of bioremediation, which is \\\"the branch of biotechnology that uses biological process to overcome environmental problems.\\\" I am helpful in the removal of cadmium, a heavy metal from water. This fact makes me non-pathogenic, so you should feel safe around me. Studies also suggest that I may be a safe, bacterial immunomodulator for the treatment of tumors. Isn\\\'t that great?! I don\\\'t mean to sound like a narcissist but I\\\'m sort of like a Super Hero...or should I say MICRO-HERO!!! <br /> <br /> DOMAIN BACTERIA <br /> -Proteobacteria <br /> CLASS<br /> -Alphaproteobacteria<br /> ORDER<br /> -Caulobacterales <br /> GENERA<br /> -Caulobacter <br /> SPECIAL FEATURE<br /> -Stalked <br /> <br /> Wanna see a cool picture of me?

    Description: My name is Streptococcus agalactiae. I am a gram positive bacteria. My cell wall is made of a thick peptidoglycan layer. Because of the thick peptidoglycan layer of my cell wall, I can’t be stained using a simple stain method; I have to be stained using the gram stain method. During the gram stain reaction I stain purple and my shape is cocci and I arrange myself as a chainlike structure. My family members are Streptococcus pneumonia, Streptococcus mutans, and Streptococcus pyogenes. I have many different factors. Some of them include respiration, metabolism, and virulence factors. These are the factors that help me to survive. In addition, I am a pathogen that causes several different diseases. <br /> The type of metabolism that I carry out is aerobic metabolism or anaerobic metabolism. I am a facultative anaerobic organism. This means that I am capable of using oxygen or not using oxygen depending on my surrounding environment to generate ATP. The type of respiration that I carry out is aerobic respiration. I am a pathogen that causes diseases in neonates. I usually live in intestine and vagina in about 10-30% of pregnant women. As a result of that, I become too friendly and cause infection in newborns by passing through the birth canal during birth; this could be very harmful. The infection that I cause could create diseases such as meningitis, osteomyelitis, and bacteremia. I also cause infection in the mammary glands of mammals such as cows and sheep. As a result of that, mammals lose their reproductive capacity due to blocked milk channels through inflammation. I possess two main virulence factors that accounts for my pathogenicity; they are pore forming toxins and a sialic acidic rich, antiphagocytic capsular polysaccharide. The capsular polysaccharide helps the bacterium to cause more infections by preventing it from being opsonized and phagocytosed. My pore forming toxins disrupt target cell membrane structures, leading to cell lysis and red blood cell damage. I am not really famous in the news, but further study is currently in process to identify the exact target to control my pathogenesis. <br /> <br /> Kingdom: Bacteria<br /> Phylum: Firmicutes<br /> Class: Bacilli<br /> Order: Lactobacillales<br /> Family: Streptococcaceae<br /> Genus: Streptococcus<br /> Species: Streptococcus agalactiae<br /> <br /> References<br /> http://microbewiki.kenyon.edu/index.php/Streptococcus_agalactiae<br /> http://www.bacteriainphotos.com/bacteria%20under%20microscope/streptococcus%20agalactiae%20microscopy.html#<br /> http://www.vetbact.org/vetbact/?artid=16#<br /> http://www.ncbi.nlm.nih.gov/pmc/articles/PMC251888/<br /> http://en.citizendium.org/wiki/streptococcus_agalactiae<br /> http://www.livestrong.com/article/71135-b-strep-symptoms/<br /> http://www.emedicinehealth.com/group_b_strep_infection/page2_em.htm<br /> <br /> <br />

    Description: Hi my name is Bacillus thuringiensis and I'm a natural pesticide.<br /> <br /> I was first discovered in 1901 by a Japanese Biologist named Shigetane Ishiwatari, while researching sudden collapse disease that killed silkworms. I was forgotten until 1911 when I was rediscovered by Ernst Berliner. You might be saying enough about my history already but wait this is important. Well, where was I...oh yeah in 1911 awww fond memories, I wiped out a large population of moths in the German town of Thuringia and Ta- Da thats where my name came from.<br /> <br /> My name is Bacillus thuringiensis aka Bt. I'm a gram positive, soil dwelling, spore forming, rod shape bacteria. I'm also in the stomach of some caterpillars. I have two relatives B. anthracis who is a toxic bacteria called anthrax and B. cereus who is notorious for causing food poisoning. Lets make it clear... we are only similar in structure because I am much less toxic. In fact I'm safe to people, pets and wildlife. You don't need a protective suit, gloves or gas mask like other pesticides because I'm organic. And I go for specific pest not all so no worries I do more good than harm. Farmers use me on food crops where pesticides would be harmful. My only downfall is I'm susceptible to degradation by sunlight hmmm what does this mean? well, simple the sun deactivates me so I strongly encourage farmers to spray me on at night. I' m aerobic and happy. You must be wondering how my magic unfold well this is how... Like I said before I'm a spore forming bacteria that produces crystal proteins. These proteins are eaten by the susceptible insects. The crystal binds to receptors in the insects intestine. This paralyzed their digestive system and the infected insect stop feeding within hours. This effect cause insect to die of starvation within several days. So there you have it... I am famous and fabulous. I'm everywhere. The next time you bite into your salad you can thank me...
