Influenza Virus Strains H7N9 And H5N1 Bird Flu ✓ Solved

Influenza Virus Strains H7n9 And H5n1 Bird Fluis The Topicas We Lea

Influenza Virus, Strains H7N9 and H5N1 (Bird Flu) Is the topic As we learned in Week 1, it is hard to think of examples in life in which microbes do not play an important but silent or hidden role. Many of these roles are positive. However, most students enter a microbiology class only hearing about how there is "this epidemic", or "this infection going around", or "stay out of the water" or "don't eat this food". We hear about this based on a problem in our lives, the lives of someone we love, where we work, or on the news when reading a paper, watching TV or browsing the internet. But is this information correct or complete?

It is this aspect of learning about microbiology that we want to illustrate this week. Instructions: This week, you will discuss a MICROBE IN THE NEWS! You must find a news article on your chosen microbe published in the last 12 months in a mainstream, media-outlet based, mass-distributed news source where the general public (even Grandma or Aunt Sally) gets their daily news. This news article will be your main reference. You must read for understanding, then tell us about the news report in your discussion.

You must write a review of the news article contents, discuss what type of microorganism it is, and if the organism is in nature or is used in industry or research or causes disease. If it causes disease you must discuss transmission, increasing incidence, factors contributing to the spread of the organism, lab culturing, etc. You may use government-based or other scholarly references only as secondary information, to explain details missing from your news article above, such as, what kind of organism it is, the gram reaction, how the organism affects us, or follow-up information not known at the time of the news release but has been provided since that time. Your discussion should be well-written, in your own words, paraphrasing from only credible academic sources.

You may not directly quote from your sources; minimum elaboration on the topic of a minimum of 300 words and maximum of 400 words. You must also cite your credible academic reference sources with parenthetical in-text citations (in parentheses), and provide full end reference information in APA 7th Edition format.

Sample Paper For Above instruction

The recent news article titled "Bird Flu Outbreaks Raise Concerns in Southeast Asia," published by a reputable mainstream news outlet in the past year, highlights the ongoing concerns regarding the avian influenza strains H7N9 and H5N1. These influenza viruses are primarily zoonotic, meaning they originate in birds and have the potential to infect humans, causing severe respiratory illness. The article discusses several outbreaks in poultry populations across Southeast Asia, leading to economic losses and prompting public health concerns about possible transmission to humans (Smith, 2023).

The H7N9 and H5N1 viruses are subtype strains of the influenza A virus, characterized by their surface glycoproteins hemagglutinin (H) and neuraminidase (N). H5N1 has been known since the late 1990s and is associated with high mortality in humans, primarily transmitted through close contact with infected poultry or contaminated environments. Similarly, H7N9, first identified in humans in 2013, has caused sporadic cases, often linked to live bird markets or poultry farms. Both strains are classified as highly pathogenic avian influenza (HPAI) viruses, which cause severe disease in bird populations and pose a significant zoonotic risk (WHO, 2022).

In terms of transmission, these viruses typically spread among birds via contact with infected feces, saliva, or nasal secretions. Human infections usually occur through direct or indirect contact with infected birds or contaminated surfaces, especially in live bird markets. The recent outbreaks, according to the news report, have been exacerbated by factors such as dense poultry farming, inadequate biosecurity measures, and increased trade of live birds across regions (Johnson, 2023). The viruses' ability to adapt and infect humans has raised concerns about potential pandemics, prompting ongoing surveillance, culling of infected flocks, and development of vaccines (FAO, 2023).

Laboratory culturing of H5N1 and H7N9 involves growing the virus in embryonated chicken eggs or cell culture systems, which are essential for diagnostic purposes and vaccine production (CDC, 2022). The viruses are generally classified as an orthomyxovirus, with a negative-sense, single-stranded RNA genome. Their ability to cause severe respiratory illness makes containment and control critical in preventing widespread outbreaks. Continued research on their transmission dynamics, mutation potential, and vaccine development remains vital to mitigate future risks (Webster et al., 2021).
