Wound botulism is caused by toxin produced from a wound infected with Clostridium botulinum. Infant botulism is caused by consuming the spores of the botulinum bacteria, which then grow in the intestines and release toxin. Adult intestinal toxemia (adult intestinal colonization) botulism is a very rare kind of botulism that occurs among adults by the same route as infant botulism. Lastly, iatrogenic botulism can occur from accidental overdose of botulinum toxin. All forms of botulism can be fatal and are considered medical emergencies.
The causative agent of the Bubonic Plague is a gram-negative coccobacilli shaped bacteria, Yersinia pestis. Yersinia pestis belongs to the family of enterobacteria and is a facultative anaerobe. Metabolism of Yersinia pestis is fermentative, and produces a thick capsule, which prevents the ability of white blood cells to ward of the infection of Yersinia pestis. There are three known diseases that are caused by Yersinia pestis; Bubonic, Septemic, and Pneumonic Plague. Bubonic plague is an infectious disease that is transmitted from small rodents and their fleas to
Parasites survive by feeding from its host. 1.2 Bacteria, common illnesses caused by bacteria are MRSA, Salmonella, Legionnaires disease, food poisoning, Pneumonia and Bronchitis. Viruses, common viruses are A common cold, measles, chicken pox and HIV. Fungi, common fungi are, Athletes foot, Ringworm and yeast infection. Parasites, common parasites are, Malaria and worms.
If the urea is broken down by H. pylori in the biopsy, there is a change in color around the biopsy on the slide. This means that there is an infection with H. pylori in the stomach. Biopsies also may be cultured in the bacteriology laboratory for the presence of H. pylori; however, this is done infrequently since other simpler tests are available. A recently-developed test for H. pylori is a test in which the presence of the bacterium can be diagnosed with a sample of stool. The test uses an antibody to H. pylori to determine if H. pylori is present in the stool.
What kinds of clinical specimens may yield a mixed flora in bacterial cultures? Oral, Skin, or GI specimens 5. When more than one colony type appears in pure culture, what are the most likely sources of extraneous contamination? Individual colonies can be picked up on the inoculating loop, or straight wire and inoculated in to the fresh agar or brother media References Cowan, M. K. (2012). MICROBIOLOGY: A SYSTEMS APPROACH, THIRD EDITION.
E.g. of antibiotic is Vancomycin. Inhibit nucleic acid metabolism: blocks the recycling of the lipid carrier molecule needed to transport the peptidoglycans in the bacteria. E.g. of antibiotic Bacitracin (Reference for all the answers to question 3 = and ) 4.
Viruses: A virus needs a host cell to replicate. Viruses are immune to antibiotics and are spread in the air or by direct contact, which mean they probably are more commonly caught from each other. They can lead to serious or sometimes deadly diseases such as aids. Virus can also cause chickenpox, common cold and influenza. Parasites: A parasite is an organism that lives in another organism.
Unknown Lab Report: Enterobacter cloacae Jessica Sainvil Professor Cupido Bio 253L1 Thu 9:30-12:30 Due Date: 12/6/12 Unknown#103 Introduction The bacterium Enterobacter cloacae isolated from the given #103 was a Gram-negative Rod. The purpose of this lab was to isolate and identify the genus and species of an unknown bacterium. It is important to identify an unknown microorganism because knowing how the bacteria work and how it is structured means knowing how it can affect humans. Unknown bacteria may also be used clinically many pharmaceutical drugs are based on products made by organisms (Katzung, B.G.2004). In order to identify the unknown organism a series of tests were performed.
Running head: Giardia Giardia Carla Linder University of Phoenix Abstract In the follow document you will learn how to identify the causes, view a list of the symptoms, and observe the treatment, diagnosis, and prevention associated with the parasite giardia also known as amoeba parasites. Giardiasis is the most frequently diagnosed intestinal parasitic disease in the United States. Giardia lamblia is a protozoa (an amoebic parasite) and it lives in the water, food, and soil. Giardia or amoeba parasites The infectious agent or pathogen that causes this infectious disease is a microscopic parasite called Giardia lamblia. Giardia lamblia is a single celled organism that causes a diarrheal infection of the small intestines and is one of the most common parasites in the United States.
P1: Explain how infections are caused by different pathogens: * Bacteria * Fungi * Protozoa * Parasites * Viruses Bacteria: Pathogens are microorganisms such as viruses or bacteria and these cause diseases in the body. Bacteria is a pathogen and are microscopic living cells that multiply at a rapid speed, once inside the body they spread toxins making the individual ill. Bacteria can cause diseases such as; * food poisoning * cholera * typhoid * whooping cough * gonorrhoea - a sexually transmitted disease Bacteria can travel in many things such as food, water or even through the air. For example if an individual is sitting next to someone that keeps on sneezing, the individual will eventually
