The opening video on a course on antibiotics, focusing on how morphology, gram stain, and other tests of bacteria can be used to create a clinically useful classification scheme.

A guide to classes of antibiotics, how antibiotics work against bacteria and mechanisms of bacterial resistance.  

This is a chart including testing information to differentiate between different bacteria causing STDs and UTIs. It also includes urine dipstick testing. Pink is gram negative bacteria and blue is gram positive. The document is in word format so it can be changed and updated as needed.  

This article describes adult respiratory tract infection. For more information, please see paediatric respiratory infections   Pneumonia is a common lower respiratory tract infection, characterised by inflammation of the lung tissue. It is almost always an acute infection, and almost always caused by bacteria. Diagnosis is typically confirmed via chest x-ray.  

THE most common cause of pathological vaginal discharge. Can be caused by an overgrowth of many types of bacteria, usually anaerobes. There is alos often a decrease in the number of lactobacilli. Not sexually transmitted   Epidemiology Affects 10% of women in the UK, but most cases are asymptomatic   Presentation  

This is a condition caused by infection of the endocardium by bacteria, or rarely, fungus. It most commonly affects the heart valves (natural or prosthetic), but can occur anywhere along the lining of the heart or blood vessels. It will most commonly occur at sites of previous damage, however, particularly virulent organisms (such as staphylococcus aureus and streptococcus pneumoniae) can infect previously normal areas of tissue; for example, Staph. Aureus will commonly infect the tricuspid valve in IV drug users.

Definitions. Before discussing SIRS along with the various sepsis syndromes, it is important to understand some basic definitions. Infection: This is the inflammatory response initiated by the presence of a micro-organisms in normally sterile tissue. Bacteraemia: The presence of live bacteria in the blood stream. This can occur in a healthy individual and present with no symptoms. Common causes include surgery, dental procedures and even tooth brushing.
