A antibody-sensitized latex for use in the determination of a bacterium belonging to the genus Nitrospira, the latex comprising a latex particle having a specific gravity of about 1.5 g/ml and an average particle size of 1.0 to 1.5 mum and an antibody adsorbed onto the latex particle which is specific to a bacterium belonging to the genus Nitrospira and has a nitrite-oxidizing activity. The antibody-sensitized latex is mixed with a sample to be tested, allowed to stand for a predetermined period of time, and then confirmed on the presence or absence of the generation of an aggregation image that indicates the presence of aggregation of the latex particles. Thus, the antibody-sensitized latex can be used in the biological nitrogen removing process for active sludge or the like or used for detecting/determining the presence of a bacterium belonging to the genus Nitrospira in water, soil or the like readily in a simple manner.
