INTEGUMENTARY CASE STUDY PART B 1. The results of the LRINEC score with 11 total points lead to the decision that Mr. Olfa has the diagnosis of the Necrotizing fasciitis. The combined test results of wound culture, MRI scan, and bloodwork verified the diagnosis, the wound culture indicated a Streptococcus and Staphylococcus infection was found in the wound site, and Mr. Olfa is diabetic therefore his immune system is weakened. Streptococcus and Staphylococcus microbes are found in small…

S. Pneumoniae bacteria are encapsulated gram-positive coccus. They are an elongated shaped cell that is arranged in pairs and in short chains and are non- motile and non –sporing organisms. S. pneumonia is cultivated in the anaerobic condition in blood or chocolate agar in thirty-seven degrees celsius and is incubated for twenty-four hours; this increases the bacteria growth by five to ten percent. The characteristic of the culture of S. pneumonia is a small smooth colony with alpha hemolysis.…

positive bacteria, spore-forming rod that produces a potent neurotoxin. Clostridium botulinum is prevalent in soil and marine sediments worldwide, most commonly as spores. These spores are found everywhere, but while the spores are generally harmless, the danger can occur once the spores begin to grow out into active bacteria and produce neurotoxins. The spores are heat-resistant and can survive in foods that are incorrectly or minimally processed.. Clostridium botulinum are rod-shaped…

An infection happens when a foreign organism attacks a human body. There are different types of organisms that can cause us harm, for example; Viruses, Bacteria and Fungi. Not all infections are the same; some are mild while some can end up being life threatening. Also, infections can be contagious; they can be transmitted by a variety of ways, for example; skin contact, airborne particles, touching an object that an infected person has touched. One of the very common and effective ways to…

have a great effect on microorganisms. In the most general sense, bacteria can grow at any temperature between freezing point of water (32°C) and the point where proteins coagulate. Between these two high and low temperatures, each bacteria type has an optimum growth temperature. An optimal growth temperature is the point at which an organism grows best, with optimal cell metabolism. If temperatures creep past the maximum, bacteria are killed. If the temperature drops below the minimum,…

hopes it will successfully reproduce in the invasive bacteria to spread throughout the body. This characteristic of phages makes it so the results are not determinate and too much of it relies on chances (Nilsson, 2014). Although there are some limitations to phage therapy, there lies many advantages in utilizing phages to fight bacteria. Arguably, one of the biggest advantages in phage therapy is the fact that they only target harmful bacteria and therefore have less side effects than…

the mixed unknown bacteria was then passed over the flame. The inoculating loop was then inserted into the broth and then carefully streak on quadrant one of the plate. Afterwards, the loop was sterilized by the flame and was allow to cool for thirty seconds so the next streak can be applied. The same concept was then applied for the different metabolic test. It is important to practice aseptic techniques to prevent contamination of results (3). A broth of mixed unknown bacteria was given and…

These include species such as Penicillium notatum and Penicillium cephalosporium. These are effective against gram-positive bacteria by inhibiting peptidoglycan synthesis (Todar,2012). There are a few types of Streptomyces including clavuligerus, cattleya, and griseus. These all work against both gram-positive and gram-negative bacteria. Another type of organism responsible for creating antimicrobial agents is Bacillus subtilis which inhibits wall synthesis and Bacillus polymyxa…

three types of media (LB, Nutrient agar and Mannitol salt) to see which type of plate would allow for better growth of the bacteria. Figure 3 shows a master plate with the bacteria that were isolated from the initial test plate. Master plates were also made for LB and Mannitol salt plates (data not shown), but only LB was as effective as nutrient agar at growing the bacteria, most likely because these are nutrient rich and complex media plates. The fact that the organism grew better in rich and…

An infectious disease is pathogenic microorganisms, like bacteria, viruses, parasites or fungi that cause diseases by spread, directly or indirectly, from one person to another. One infectious disease is Clostridium difficile, a nasty bacterium that affects the digestive system, specifically the colon. A disease that can start of pretty mild and lead to life-threatening inflammation of the colon. Clostridium difficile is a bacterial infection in the digestive system which has the same symptoms…
