References & Citations in text (10 points) Failing to Cite your course in text and or failing to provide acceptable references with links will result in a zero as this is considered plagiarism) List all references used to gather information. These references are listed at the end of the paper on a separate reference page Reference page(s) do not count in the page requirement Proper citation is used throughout the paper (intext citations, quotes are cited correctly etc) Make a new reference for every page. This means that if you use the CDC and you click on 5 links and learn information from all 5 links you cite all 5 CDC pages individually. DO NOT cite cdc.gov this is not the actual page within the CDC that you learned your information.

Your references must take the reader to the direct page you learned the material from. This applies to all websites. IF you navigate off a page onto another one then it gets its on reference. Acceptable sources are used Ever sentence should have a citation to go along with it. The only way around this is if you knew the information prior to taking this course.

If in doubt cite your source. Format your references using the MLA format - all links provided must be working links Acceptable Sources Your textbook Centers for Disease Control and Prevention World Health Organization MicrobeWiki Any scientific journal article A news article is not a source for facts only use if you are presenting about a recent outbreak or drug development for your pathogen. DO NOT USE Wikipedia, youtube, course hero, study blue, etc. You want to use reputable reliable resources. Wikipedia is not an acceptable source!!!

You may use a source other than those listed above if it is another textbook or a reputable scientific website. You can ask me if you are unsure! Example of writing that has proper citations. This example does not include any quotes. Note that every sentence is cited.

If in doubt cite your source. Rosalind Franklin was female scientist who specialized in physical chemistry and X-Ray Crystallography in the 1950’s (1,2). She is now well known for her work on DNA however she also worked on viruses that impacted crops, polio, and other research was used in the production of gas masks (1,2). Dr. Franklin’s work would lead to cancer which eventually took her life at the age of 37 (2).

Although Watson and Crick are credited with the discovery of the structure of DNA without Franklin’s photo 51 they would not have been able to publish their findings and receive Nobel prizes (1). Franklin used x-ray crystallography to image DNA showing its double helix structure in 1952 in the same issue of Nature as Watson and Crick without knowing her unpublished work had led to their discovery (1,2). The images that Dr. Franklin took over the course of her research are invaluable to the advancements in biotechnology as biotechnology is rooted in our structural understanding of DNA (3). Our understanding of DNA and how Adenine binds to Thymine and Cytosine binds to Guanine with hydrogen bonds to create the double helix model has led to advancements such as insulin production using microorganisms (3).

Example of what you could NOT say: Hantavirus pulmonary syndrome can be found in the Western Hemisphere, including here in the U.S.(1) This example is plagiarism. why?

It is not quoted. I used 5 or more words in a row that match the source. See the underlined portions and how they match. Example of what you could say: Hantavirus pulmonary syndrome is knows to be found in the United States. It can also be found in other Western hemisphere countries as well (1).

This example is not plagiarism. It is paraphrased. The same information is being shared but in a different mix of words. If you MUST quote something be sure you use quotation marks. There may be occasions where a quote is necessary but they should be few and far between.

You should have no more than 5 sentences that are quoted in the entire paper. Example with a quote. The CDC states "Hantaviruses found in the Western Hemisphere, including here in the U.S., can cause hantavirus pulmonary syndrome (HPS)" (1).

Paper for above instructions

This paper explores Candida albicans, a common fungal pathogen responsible for various human infections. Candida albicans is clinically important because it can transition from a benign commensal organism to an opportunistic pathogen, particularly in individuals with compromised immune systems (CDC, 2024a). The organism inhabits mucosal surfaces and is normally harmless, but disruptions to the host’s normal microbiota enable uncontrolled proliferation (Mayer et al., 2013). Understanding its biology, pathogenicity, transmission, and treatment options allows healthcare professionals to diagnose and manage infections effectively (WHO, 2023).

Organism Basics and Cell Structure

Candida albicans is a fungus belonging to the kingdom Fungi and phylum Ascomycota (CDC, 2024b). Its scientific name is Candida albicans, and while it has no widely used common name, it is often simply referred to as "Candida" in clinical settings (Pfaller & Diekema, 2007). The organism is unicellular but can shift into multicellular structures such as pseudohyphae, giving it morphological flexibility (Mayer et al., 2013). This dual nature allows it to adapt to different host environments (CDC, 2024b).

Candida albicans cells contain a nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and a thick cell wall composed primarily of glucan, chitin, and mannoproteins (Nobile & Johnson, 2015). The fungal cell wall differs from bacterial and human cell structures, making it an important antifungal drug target (CDC, 2024b). A unique feature of this organism is its ability to switch between yeast and hyphal forms, known as dimorphism (Mayer et al., 2013). This transition helps it penetrate tissues and escape immune defenses (WHO, 2023). The organism also produces adhesins, biofilms, and hydrolytic enzymes that contribute to pathogenicity (Nobile & Johnson, 2015).

Pathogen Life Cycle

The life cycle of Candida albicans involves growth as budding yeast cells and transitions into filamentous forms under certain conditions (Mayer et al., 2013). Replication occurs primarily through asexual budding, where daughter cells form and separate from the parent (Pfaller & Diekema, 2007). Environmental cues such as temperature, pH, nutrient availability, and serum exposure trigger morphological changes (CDC, 2024a). In the host environment, this dimorphic shift enhances its virulence, enabling deeper invasion of tissues and evasion of immune responses (WHO, 2023). The organism can also form resilient biofilms on medical devices, creating persistent infections that are difficult to eradicate (Nobile & Johnson, 2015).

Disease, Symptoms, and Epidemiology

Candida albicans is responsible for various diseases including oral thrush, vaginal candidiasis, cutaneous candidiasis, and systemic bloodstream infections known as candidemia (CDC, 2024c). Transmission typically occurs endogenously from an individual’s own microbiota, although hospital environments and contaminated devices may also contribute (Pfaller & Diekema, 2007). Populations at risk include immunocompromised individuals, diabetics, the elderly, newborns, and patients using broad-spectrum antibiotics (WHO, 2023).

The reservoir of Candida albicans is primarily the human gut, skin, and mucosal membranes (CDC, 2024c). The organism is globally endemic and is one of the most common fungal pathogens affecting humans (WHO, 2023). Symptoms depend on the infection site. Oral candidiasis may cause white patches, soreness, and difficulty swallowing, whereas vaginal candidiasis is characterized by itching, burning, and discharge (CDC, 2024c). Systemic infections may produce fever, chills, and organ dysfunction, often progressing rapidly and carrying high mortality (Pfaller & Diekema, 2007).

The progression of infection begins with overgrowth at a mucosal surface, followed by tissue invasion if left untreated (WHO, 2023). Complications include systemic dissemination, organ failure, and septic shock, particularly in hospitalized patients (CDC, 2024d). Mortality rates for systemic candidiasis can reach up to 40% despite available treatments (Pfaller & Diekema, 2007).

Diagnosis, Treatment, and Prevention

Diagnosis varies depending on the infection type. Oral and cutaneous infections are typically diagnosed based on clinical appearance, while laboratory tests such as cultures, PCR, and antigen detection are used for systemic infections (CDC, 2024d). Blood cultures remain the gold standard for diagnosing candidemia, although they may take days to return results (WHO, 2023).

Treatment includes antifungal medications such as azoles (fluconazole), echinocandins (caspofungin), and polyenes (amphotericin B) (CDC, 2024d). The choice of therapy depends on infection severity and patient characteristics (Pfaller & Diekema, 2007). Topical antifungals may be used for superficial infections, while systemic antifungals are necessary for severe or recurrent disease (WHO, 2023).

Prevention strategies include maintaining good hygiene, controlling underlying medical conditions such as diabetes, and reducing unnecessary antibiotic use (CDC, 2024e). In hospital settings, proper sterilization of medical devices, hand hygiene, and antimicrobial stewardship play critical roles (WHO, 2023). Immunocompromised patients require close monitoring to prevent systemic infections (Pfaller & Diekema, 2007).
