The purpose of this lab was to determine the identity of an unknown bacteria slant culture using a series of differential tests. The tests used to identify the unknown bacterial culture included: Gram stain, mannitol salt agar, coagulase tube test, and an antimicrobial susceptibility test. The tests selected were based on the results of a gram stain.…
The streak for isolation was chosen to see the formation of the different colonies and to see if the bacteria would cause growth on the plate. After observing the plate, it could be seen that the unknown had growth and formation of colonies. The Gram stain was chosen next to determine if the unknown was gram-negative or gram-positive. After looking at the gram stain under the microscope with the oil immersion it could be determined that the unknown was gram-negative due to the fact that the bacteria was pink in color and rod shaped. After determining the unknown was gram-negative, other bacteria’s were able to be eliminated from the options. The Triple Sugar Iron Test was chosen next because the unknown could be tested for glucose fermentation, lactose fermentation, sucrose fermentation and sulfur reduction. If the organism is able to ferment glucose and lactose and/or sucrose it will turn the medium yellow throughout (Leboffe & Burton 329). When the Triple Sugar Iron Test was complete, it showed a yellow butt, yellow slant and gas production. This determined that the unknown ferments glucose and one or both of the other sugars. The gas was produced by fermentation. The color change in the agar brought the unknown down to two options of unknowns, Escherichia coli or Hafnia alvei. The SIM medium test was chosen next to see sulfur reduction, indole production from tryptophan…

Also known as Valley fever is an infection that is caused by the fungi Coccidioides. The fungus grows in soil found in the southwestern part of the United States as well as Mexico and Central/South America. Those living in these designated areas can contract this disease by inhaling the fungal spores in the air. This is considered a self limiting respiratory infection so most individuals that are infected present with mild to no symptoms at all. A patient with this disease can present with the following signs and symptoms anywhere from 1-3 weeks after breathing in the fungal spores due to its incubation period of 10-16 days. The symptoms consist of, fatigue, cough, SOB, fever, chills, HA, night sweats, muscle aches/joint pain, rash on the upper body or legs (erythema nodosum). These symptoms can last 7-30 days or up to several months depending on the severity. In regards to patient history, it is important to get a travel history especially if they went to an endemic area to determine their risk of exposure. Some exam findings could be respiratory manifestations such as rales, rhonchi, bronchial breath sounds, or decreased breath sounds. Skin findings could consist of diffuse, maculopapular rashes or urticaria that may progress to erythema nodosum or erythema multiforme after 3-21 days. Abscess formation can also be found on PE and unifocal bone or joint lesions if MS involvement. It can involve several organs such as the spleen, liver, lymph nodes, and the CNS can be involved resulting in meningitis.…

The objective of this report was to identify an unknown microorganism through several differential media tests. Over the course of a couple weeks, ten tests were performed. First, a gram stain was performed, indicating the bacterium was gram negative. An aerotolerance test determined that the bacterium was a facultative anaerobe. Next, a negative result in the methyl red test indicated that no mixed acid fermentation occurred. The DNase test was performed and yielded a positive result. The SIM test provided two outcomes, that the bacterium did not reduce sulfur nor produce indole from tryptophan. Afterwards, the bacterium was determined to be positive for lysine decarboxylation and citrate. The purple broth and triple sugar iron tests both indicated gas production. The purple broth test was positive for fermentation, and the triple sugar iron test indicated that the bacterium fermented glucose and sucrose. Finally, the bacterium was urease negative.…
The causes of Nf1 are a mutation on the 17 chromosome at q11.2. The mutation mainly affects the development of nerve cells and tissues. The changes in nerve tissues cause tumors or other abnormalities. The tumors can be harmless, in some situations. Nf1 is dominant and autosomal; meaning it will affect males and females equally. Nf2 is a slightly different. Nf2 is characterized by a mutation on the 22q12.2 chromosome. Nf2 is also autosomal dominant. The mutations has significant physical causes consisting of meningiomas and other symptoms consisting of a lot of big words that not even spell check understands. The main idea of the symptoms is that they’ll grow deformities, usually…

Invasive aspergillosis is an infection caused by the fungus of the genus Aspergillus. The fungus immunocompromised individuals due to weakness in defense mechanisms. While it has been largely accepted that Aspergillus species is recognized by cellular receptors and attacked by neutrophils, the radiological and macroscopic findings linking infection with neutropenia remain unconfirmed. However, the fungus survive these attacks and germinate causing the disease. Histopathological changes occurring at the site of infection and altered tissue structures generally result from an extensively complicated interaction between the causative microbes and tissue responses. Methods for diagnosing invasive aspergillosis include serological, imaging and…
Background: A meta-analysis indicates that the use of foot orthoses seems to improve foot disability and reduced pain related to chronic plantar fasciitis. Preliminary evidence suggests that plantar fascia thickness greater than 4mm appears related to foot disability in individuals with chronic plantar fasciitis. However, it seems contradictory that inserting more plantar thickness, via foot orthosis or taping, to the already thickened plantar fascia, may be linked to reduced pain and disability. An alternate rationale could be that wearing foot orthosis may augment the sensory perception of these individuals resulting in enhanced outcomes. Sensory perception (i.e. tactile acuity) is robustly linked with cortical processing of tactile stimuli in the primary somatosensory cortex. However, there is a paucity of research that has concurrently described the persistent pain, plantar fascia thickness, range of motion (ROM) and tactile acuity of the involved versus the uninvolved foot.…
