The structure of a cow’s placenta means that antibodies cannot cross from her bloodstream to that of her calf. If you consider antibodies as an army (like this Bastille day parade from a previous post), there is a specific troop that is always on the lookout to fight just the one bacteria or virus. There are also specific antibodies for specific diseases. Ig G, for example is found in the blood, while Ig A is found inside the intestines. If they find any, they hold onto them until the body’s white blood cells come along and eat them up.Īntibodies are also known as immunoglobulins (Ig), and there are different types of Ig for different areas of the body.
