There would be an increased strain on local governmental finances as many more families would require assistance. Many charitable groups would find an increase request for assistance.

viruses share some similarities. For instance‚ both bacterial and viral infections are caused by a microbe. Bacterial or viral infections occur when microbes enter a body and reproduce. Once the microbes reproduce they can cause mild‚ moderate‚ or severe disease. They can cause acute infections which are very brief‚ chronic infections which can last anywhere from a week to a lifetime‚ or latent infections‚ which may not have symptoms at first‚ but symptoms can arise over a period

Anthrax Pathogen Info: • Rod-shaped‚ spore-forming bacteria with square ends • Spores are inactive until they enter a live host; can survive for decades prior to infection. • Pathogenicity: • Forms a protective protein capsule to avoid phagocytosis • Anthrax toxin (all from RCSB source‚ Anthrax toxin.‚ other journals that are bookmarked) • Three parts (EF and LF attack signaling parts of cell) • Edema factor (EF) is an adenyl cyclase enzyme. It attacks ATP‚ turns it into cyclic AMP‚ and creates

Introduction Throughout this assignment I am going to be looking into the health and social topic of communicable and non-communicable diseases. I will be investigating into various aspects of two specific diseases. A high level of knowledge will be demonstrated with a detailed description of both communicable and non-communicable diseases as well as an understanding of epidemiology. I will then find a communicable and non-communicable disease example and describe the biological basis of each disease

respiratory infection of horses caused by an orthomyxovirus of the genus Influenza A. Influenza A viruses can be divided into sub-types on the basis of the antigenic reactivity of the surface glycoproteins‚ the haemagglutinin (H1-H16) and the neuraminidase (N1-N9) molecules (Fouchier et al.‚ 2005). Equine influenza (EI) is caused by two subtypes H7N7 and H3N8. Outbreaks due to H7N7 are limited as the isolation of the virus has not been reported since last two decades. Recent infection in India (2008-2009)

(2 pts) Why are patients with cystic fibrosis prone to infections with Pseudomonas aeruginosa? Pseudomonas aeruginosa is an opportunistic infection that usually does not affect healthy patients‚ but is particularly detrimental in patients with cystic fibrosis. This is because they are antibiotic resistant to a certain extent. Paired with this‚ patients with cystic fibrosis have a decreased ability to produce mucous membranes‚ making it easier for biofilms associated with P. aeruginosa (Lyczak et

Gangrene: Gangrene is when there is dead tissue in an area of the body. This occurs when there is not any blood circulating to a part of the body. A person is at high risk of obtaining gangrene if they are a diabetic‚ had a serious injury‚ or a bad infection. The most common sites of gangrene are the toes‚ fingers‚ hand‚ and/or feet. There are two main types of gangrene: Dry Gangrene and Wet/Moist Gangrene. Dry gangrene is caused by the reduction of blood flowing to the arteries. It appears gradually
