The inflammation is caused most often by an infection from certain viruses or less often by bacteria‚ their toxins‚ parasites‚ or an adverse reaction to something in the diet or medication.

Understand the causes of Infection 1.1 Identify the differences between bacteria‚ viruses‚ fungi and parasites Bacteria come in 3 main shapes; spherical which are known as cocci‚ rod shaped which are known as bacilli or vibrio‚ spiral which is known as spirilla or spirochetes. Bacteria is found in everything for e.g. soil‚ water‚ animals‚ plants‚ radioactive waste. The only place they aren’t found is where humans have sterilised. They can cause illnesses like tuberculosis‚ tonsillitis‚ and

What Are STDs? STDs are sexually transmitted diseases. This means they are most often -- but not exclusively -- spread by sexual intercourse. HIV‚ chlamydia‚ genital herpes‚ genital warts‚ gonorrhea‚ some forms of hepatitis‚ syphilis‚ and trichomoniasis are STDs. STDs used to be called venereal diseases or VD. They are among the most common contagious diseases. More than 65 million Americans have an incurable STD. Each year‚ 15.3 million new cases are reported; half of these infections are lifelong

THERE ARE FOUR (4) MAIN TYPES OF DISEASES: * PATHOGENIC * DEFICIENCY * HEREDITY * PHYSIOLOGICAL Pathogenic diseases are caused by organisms (parasites). E.g. micro-organisms causing STDs‚ malaria‚ smut; macro-organisms: head louse‚ blood fluke. Pathogenic diseases can be caused by bacteria‚ viruses‚ fungi etc. Here is a short list of pathogenic diseases due to pathogenic bacteria that infect human: * ATHLETE’S FOOT * CHOLERA * TUBERCULOSIS * TETANUS

Bernot wrote it so hopefully it is useful • Describe the structure of DNA and discuss how it facilitates the ability of DNA to act as genetic material • Compare and contrast prokaryotic and eukaryotic chromosomes • Describe the process of DNA replication as a semi-conservative process. Compare and contrast the synthesis of the leading and lagging strands in DNA replication. • Explain

types are caused by many different types of bacteria. Infections are caused by micro-organisms which are known as pathogens‚ there are three sources of pathogens; • Within a person’s body- called endogenous • From other people through touching‚ coughs or sneezes called exogenous • From contaminated equipment or elements such as dust or water known as environmental. Viral infections are different than bacterial because they are caused by viruses which are smaller than a bacterium or fungus

Unit 265 Outcome 1 1.1 A: Bacteria: Bacteria exist everywhere‚ inside and on our bodies. Most of them are completely harmless and some of them are very useful. But some bacteria can cause diseases‚ either because they end up in the wrong place in the body or simply because they are ’designed’ to invade us. Bacteria can infect humans‚ plants or animals. B: Viruses: A virus is a small infectious agent‚ too small to be seen by the naked eye. They can’t multiply on their own‚ only inside the cells of
