Does eating camel meat invalidate the prayer if one forgot to perform ablution before it?

Eating camel meat nullifies ablution (Wudu'). Therefore, every prayer performed after eating camel meat without performing Wudu' is invalid, based on the Prophet's (peace be upon him) saying: "Allah does not accept the prayer of anyone of you if he passes wind, until he performs Wudu'." Those prayers must be made up.
