Biv - Describe the procedure to follow if you wanted to raise a grievance at work. You may describe this in writing or produce a flow chart or diagram.

Fever, swelling around initial infection site, parasites in blood, sometimes asymptomatic, rarely debilitating or life threatening problems can occur.

Next I performed a KOH test to further confirm that my organism was a Gram-negative species. For the KOH test, I added 3 drops of 10% potassium hydroxide (KOH) to a small drop of distilled water onto a clean microscope slide, transferred a visible clump of organism to the KOH solution using my inoculating loop. I than mixed the cells into the solution using small, circular motions for 60 seconds and then lifted up the loop to look for what appears to be a “stringing” affect which means it’s confirmed that it is gram- negative species. Next, I created a streak plate using nutrient agar so that I could see pure culture of my organism. I aseptically obtained a loop full of my organism and gently inoculated one quarter of the nutrient agar plate by running the loop back and forth across the surface. I then flame sterilized the inoculating loop, allowing it to cool for 10 seconds, and then streaked the organism from quadrant I into quadrant II using a zigzag motion technique. I repeated those steps streaking from quadrant II to quadrant III and then streaking from quadrant III to quadrant IV. Once completed, I put the streak plate in the incubator at 37° for 24-48 hours. 48 hours later, I check my streak plate and it had a lot of growth on it. I was able to determine that the organism was definitely an off white color, opaque. The IV quadrant was the quadrant that best

Once anyone gets a bite from a mosquito the side effects and symptoms won´t start showing up until 3-15 days after the initial bite, that is only if the mosquito was infected. Some cases are a lot worse than others (Centers). The mild or less severe case would be a headache and a fever. The more severe case would be headache, fever, body ache, swollen lymph glands, and in the worst possible scenario, death. No one can help weather you get a really bad case of

Table 3 shows Gram stain results that indicated C. Freundii as a gram negative bacterium in rod shapes scattered in singles and some in pairs. Each gram stain produced the same results. The Bartholomew and Mittwer method of endospore staining indicated that C. Freundii tested negative for endospore formation. Table 4 shows the biochemical test results of the unknown and the official test results for comparison.

C.  See a healthcare provider if nausea, vomiting, and joint pain occur after a tick bite.

by Yersinia pestis. Several species of rodents host this bacterium, usually contracted from flea bites. There

This experiment was given to us to utilized previous knowledge learned throughout the semester to identify a gram negative unknown bacterium. We had to first learn the difference between a gram negative and a gram positive organism. We started off with doing gram stains to determine whether it was positive or negative. Based on the gram stains, a gram positive stains purple and a gram negative stains pink. A gram positive stains purple because the cell walls is made of a thick peptidoglycan layer and doesn’t

The incubation periods ranges from 3-30 days, the first symptoms usually appears in 7-14 days after the bite. Whereas this disorder can be asymptomatic, typical symptoms include fever, migratory polyarthralgia, headache, myalgia, fatigue and a characterized isolated skin called lesion that progress with its multiplication. If left untreated, the disease can affect the joints, the heart, and nervous system, that may exhibit neurological findings including meningitis and other neuropathies(Goolsby, Grubbs, & Goolsby, 2014)("Lyme Disease| Lyme Disease | CDC,"

Its venom destroys the walls of blood vessels near the site of the bite, sometimes causing a large skin ulcer.

Unknown lab report# 24 Introduction Microbiology is a study of organisms that surrounds us every day. It requires an educational understanding to identify organisms, and the ability to distinguish different bacteria’s. In applying the learning process of the different bacteria’s, unknown bacteria samples are given to be studied and identified.

The purpose of this study is to identify four unknown organisms. The unknown organisms have been assigned randomly to six-research groups by Professor Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi, or protozoans. All living organisms are organized into one of three domains of life, Bacteria, Archaea, and Eukarya.

The bases of this experiment was to discover the identify of the unknown from three possible specimens: Klebsiella pneumonia, Escherichia coli, and Enterobacter aerogenes. Utilizaing the T streak technique, the bacteria was isolated into pure colonies for further study. The Gram Stain method was used to identity the morhphology of the bacteria such as the shape and whether the bacteria was Gram positive or Gram negative. Biochemical test were also used to help identify the unknown bacteria. The biochemical test used was the Triple Sugar Iron Agar, Sulfur Indole Motility test, Methyl Red test, Voges-Proskauer test, Citrate test, Urease test, and the Gelatin test. After observing the morphology of the bacteria using the Gram Stain method and utilizing all the possible biochemical test, the bacteria was identified to be Enterobacter aerogenes.

​The origin of the disease has been described at the end of the movie where we find out that a bat with a virus known as paramyxovirus that infects a pig. The pigs that are for human consumption were located near a forest that was being cut down. The pig in turn infects human beings of the earth through a chef. The agent which is very infectious is known as MEV-1 and its potential spread is estimated at 6-7 which suggests that the virus is highly transmissible from one person to the next. The virus has been compared to that of a smallpox virus with a mortality rate of up to 30%.

A number of studies have supported the theory that the virus had originally occurred in animals previous to human infections.5 The MERs-CoV virus is a type of coronavirus that has been known for infecting both birds and many species of mammals. These types of infections are commonly referred to as zoonotic diseases because the pathogens are able to be transferred from animals to humans. Zoonosis can happen with or without a vector in order to spread the infection. Although the exact origin of the MERs-CoV infections is unknown, there has been convincing research performed that has found related types of coronaviruses in bats and camels. According to the Center for Disease Control and Prevention, the coronavirus is found in multiple species and can cause respiratory illness and gastrointestinal upset.
