Causes and Spread of Infectious Diseases

Causes of Infectious Diseases Differences between bacteria, viruses, fungi and parasites Bacteria, fungi and parasites are all considered as ‘living’ things,. Bacteria are single celled microorganisms that can only been seen through a microscope, they collect their nutrition from their surrounding and unlike viruses, they do not need a living host to reproduce. Viruses are difficult to destroy because they are enclosed in a protein coating. Viruses are disease-producing agents, far smaller than bacteria. Viruses are not considered as living because they are unable to reproduce. Fungi are placed…...

Infectious Diseases of Urinary Tract Caused by Ecoli

Abstract: E.coli was reported as the most predominant uro-pathogen, which may be difficult to treat as they exhibit multidrug resistance and sometimes grow in biofilms. Because honey exhibits antimicrobial activities against a wide range of bacteria, this study was undertaken to study resistance pattern and biofilm formation among uropathogenic E.coli, and evaluate the use of Egyptian honey as an antibacterial agent. Uropathogenic E.coli strains were collected and susceptibility test by commercial antibiotic was performed. Extended-spectrum beta-lactamase (ESBL) detection was assessed…...

Dengue Fever Basic Points and Symptoms

What is dengue Dengue is a viral infection transmitted by the bite of an infected female Aedes mosquito. Estimated 100 million cases of dengue fever occurring throughout the world annually.

Infection control and universal precautions

The principle of infection control is something that is becoming increasingly important in hospitals and healthcare settings. This is primarily because of the hardship and suffering it causes to the patient who acquires an infection whilst in hospital and also because of the cost it brings to our already under funded hospitals from increased stays and healthcare workers falling ill. The author will discuss the principal of infection control and by demonstrating the effectiveness of techniques such as hand washing…...

The Study of Germs

For as long as humans have actually been on this planet, the microscopic life kinds that we call germs, or pathogens, have been here too. For all this time they have been increasing in the soil, in the water, and in our bodies. They remain in the mouth, on the skin, and even in crucial organs. However that is not always a bad thing, since human beings might not live without germs. Some germs, or "microbes" help absorb food, while…...

Spread of Infection by Microorganisms

The majority of bacteria’s are harmless and beneficial to the human body but some can cause infectious diseases.

Emerging Infectious Diseases

Emerging infectious diseases are diseases that are new or changing, and are increasing, or have the potential to increase in incidence in the near future. (Pearson, Microbiology) Some important contributing factors to the development of EIDs are evolutionary changes in existing organisms, the movement of previously identified diseases to new geographic locations and populations by modern transportation, and increased human exposure to previously undocumented, uncommon infectious agents in areas of ecological growth or change. This includes previously uninhabited areas that…...

The Pandemic Virus

The virologists determined the identity of the virus causing the disease by taking blood samples from the people who were sick or who were getting sick, the n they put them under the microscope and studied them. They tracked the epidemic down by following where people were getting sick; the virologists finally followed the virus back to the ship that was carrying all the animals and the monkey. They conquered the virus by taking the serum from the host after…...

Travelling and Health

People traveling to high altitudes for work or pleasure are increasing day by day. The rewards of such travel are generally at the risk of developing of one of several forms of acute altitude illnesses and/or worsening of underlying medical problems.
