Bacillus anthracis

1. Non-pathogen name: Bacillus subtilis 2. Description of non-pathogen: B. subtilis is a mesophilic, gram-positive bacillus that is commonly found in soil, although it can also survive in plants (1). B. subtilis are facultative aerobes, using butanediol fermentation or nitrated ammonification when oxygen is unavailable (1). The bacillus is motile by using a single flagellum and commonly forms biofilms which contain several B. subtilis all traveling in the same direction (1). It has a circular…

Anthrax is a disease caused by the microorganism Bacillus anthracis. This primary pathogen is a zoonotic, aerobic, spore-producing bacillus which is gram positive when tested under a microscope1-4. It is particularly dangerous because of its hardy spores which can survive despite exposure to higher temperatures, light, and multiple disinfectants3. Once the bacteria are picked up by grazing herbivores, the spores begin to germinate and become virulent. As the bacteria continue to develop in the…

was able to gather results that revealed that the environmental isolate is a Gram-negative bacillus that grows best at 37 °C. Additionally, it is a non-motile obligate aerobe that produces endospores, possesses a capsule, and is a non-hemolytic microorganism. Through these experiments along with other significant tests one was able to determine the species as Bacillus anthracis. The species Bacillus anthracis can live in the soil where the microbe traveled from onto the statue. Introduction:…

key differences in the composition of their cell walls. These differences often have a direct influence on what the bacteria does, with some Gram-negative bacteria being pathogenic in nature. Gram positive bacilli Sopre foming bacillus cereus- food poisoning, bacillus anthracis, anthrax, clostridium tetani-tetanus; clostridium botulinum- botulism; Clostridium perfringens- gangrene; Clostridium difficile- colonitis Non sporing: listeria monocytogenes- food poisoning; corynebecterium diphtheria…

Here in the United States anthrax is not common, however it can be possible to contract due to rare outbreaks that occurs with in the wild livestock. Some examples of animals that can carry Bacillus anthracis cattle, deer and sheep. There are different ways to contract anthrax, these ways are called; Inhalation anthrax, cutaneous, gastrointestinal anthrax, and newest findings called injection anthrax. The most dangerous way to contract anthrax…

Did you know about fifty-one percent of people die of anthrax a year? Anthrax is a serious infectious illness caused by a microbe called Bacillus anthracis that lives in soil. The good thing about anthrax that it is hard to get in the United States. Anthrax history has been widely more common in 2001. It was first discovered from ancient origins in 1250 BC. Anthrax is known as one of the worst biological attacks in the country. So far anthrax has attacked resulted in five deaths and 17 illness…

Every day we hear on the news about how many health problems we have as humans. When we find a cure for one health problem there are three more health issues that pop up. People have become ignorant about politics and what is happening around them. Worst of all people have become ignorant about what is in the food they are putting in their bodies. I have been looking at the pros and cons to using pesticides and what I have found in my research surprised me. Now the bad side of pesticides…

done by Streptococcus mutans using extracellular enzyme glucosyltransferase in the oral cavity. Individuals infected with capsulated bacteria like Streptococcus pneumonia, Klebsiella pneumonia, Neisseria meningitides, Haemophilus influenza, Bacillus anthracis, Yersinia pestis and others show anti-capsular antibodies in their serum. Capsule is impermeable to biological dyes routinely used, therefore they cannot be stained. Negative staining which colours the background is employed to demonstrate…

1. A 39 year old US postal worker notices an area of redness and swelling on his left lateral forearm. Six days later he notices that the rash, which is painless, now appears black and swollen. He becomes concerned and goes to the emergency department, where he is subsequently diagnosed with cutaneous anthrax. Which of the following mechanisms is most likely associated with the swelling that surrounds the black rash? A. SNARE protein cleavage B. Overactivation of adenylate cyclase by disabling…

In the 1940s, antibiotics were widely introduced as a cure for common types of diseases. However, some microbes were able to resist the impacts of these drugs, in other words, the pathogen remained alive. In order to help resolve the crisis, antibiotics were found through screenings of soil microorganisms. However, soil microorganism’s antibiotics were depleted by the 1960s and their antibiotic effects were unable to be replicated through synthesis. In this experiment, the researchers developed…
