Enterococcus

in pairs, short chains, and chains. Some are facultative aerobes, and some are anaerobic. Some species also are hemolytic, and others are non-hemolytic. Many species cause disease in humans. Streptococcus faecalis, a penicillin-resistant group D Enterococcus and normal inhabitant of the GI tract may cause infection of the urinary tract or endocardium. Streptococcus pneumoniae, formerly Diplococcus pneumoniae, causes a majority of the cases of bacterial pneumonia in the United States.…

Lactobacillus is the most commonly used bacterial species (Swyers et al. 2008). A study conducted by Al Jassim et al. recorded that several species of Lactobacillus were located throughout the equine gastrointestinal tract. This concludes that these microbes have the ability to adapt to pH changes and survive in different environments. L. mucosae and L. salivarius were found to be the most abundant. L. salivarius, specifically, was cultured from the stomach, colon, and rectum, suggesting its…

Maximum bully dog food reviews. Maximum Bully Dog Food has a special formula that is planned to help these dogs, both a Boston terrier and an American pit bull terrier, acquire best nutrition for their unique needs. Bully breed are special dog breed that was originally trained for blood sports, such as dog fighting and bull baiting. These dogs are famous for their extremely energetic and aggressive behavior, a giant brick-like head, wide jaws, and a medium-sized, muscular appearance. Example of…

present. Lastly I did the catalase test, this time not because of its simplicity, but because it would verify what bacteria was present. This time the catalase test was negative. It did not produce any bubbles. This confirmed that bacteria two was enterococcus faecalis, as it was the only negative catalase bacteria on our…

Bacteria are one-celled organisms. When looked at under a microscope, they appear to be balls, rods, or spirals. Contrary to popular belief, most bacteria are actually good for other organisms. Under 1% of bacteria on Earth cause disease, and the bacteria that do can usually be treated with antibiotics (“Bacterial Infections: Medline Plus,” par 1). The common image of bacteria is that they are all horrific organisms that cause disease. While people should most definitely wash their hands to…

The purpose of the research was to potentially find a new bacteria that is capable of producing an antibiotic against one or more of the six ESKAPE pathogens (a group of pathogens that are resistant to most if not all current antibiotics). All research protocol was based on the Yale Small World Initiative and the third edition of Microbiology Laboratory Theory & Application. One bacteria from a sample of soil collected (colony #18) was tested for its ability to produce antibiotics against two of…

Introduction The Gram stain is a valuable tool to microbiologists in identifying the cell well composition of prokaryotic species. The underlying process revolves around a series of chemical dyes, and their propensity to bind to peptidoglycan polymers in the cell wall. The results allow scientists to infer properties about the outer coating of an organism and is often the first step in identifying an unknown species. For the purpose of our experiment, the results of the Gram stain will be as…

Bacterial identification is crucial to the healthcare setting in that it helps prevent or reduce disease. Multiple tests were conducted in attempt to identify the unknown microorganism that was swabbed from a cheek, and their materials, methods and results were described. The goal of the unknown lab experiment was achieved by identifying the genus and possible species through interpretation of the results found. Microbiology is the study of microscopic organisms. These organisms are virtually…

of one’s mind, the level of widespread panic, promoted by people who side with heavier regulation, is a huge overreaction. The FDA has stated that “NARMs data indicates that first line treatments for all four bacteria that we track—Salmonella, Enterococcus, E. coli, and Campylobactor—are still effective” (“Fighting”, 2013). This is proof that the way antibiotics are being handled today is satisfactory. Of course, it is completely fine for people to consider how resistance may eventually affect…

The purpose of the unknown experiment is to understand and identify a gram positive and a gram negative. Bacteria can be very helpful in clinical uses and many pharmaceutical drugs are based on the organism. Knowing how a bacterium works and how it is structured can be crucial to determine how it affects each individual. Several biochemical tests were performing to separate and determine the identities of the microorganisms. Broth tube number 31 containing unknown microorganisms. One of the…
