What is immunology?

Immunology has its origins in the study of how the body protects itself against infectious diseases caused by microorganisms, such as bacteria, viruses, protozoa, and fungi, and also parasitic organisms, such as helminth worms.

Gut Microbiota and Obesity

Between 1,000 and 1,150 bacterial species have potential to colonise the human gastro-intestinal (GI) tract, with each individual harbouring around 160 different species (1). The composition of the gut microbiota has received attention as an etiological factor in the development of obesity. It is sensitive to dietary changes and able to alter composition within hours in both animals and humans (2-5). Independently of diet, the gut microbiota is able to influence host inflammatory responses.
