This invention is a diagnostic plate that can be used to select antibiotic combinations with efficacy against microorganisms growing as a biofilm. The plate allows growth of biofilm on a plurality of projections, and the subsequent simultaneous challenge of biofilms on all projections of the plate to independent concentrations and combinations of anti-biofilm agents. Resistance of microorganisms to antibiotics is higher when they grow as a biofilm, as compared to when they grow in a planktonic state which is usually used to determine their level of antibiotic sensitivity. Growth of microorganisms that slough off the biofilm in the anti-biofilm agent challenge determines the Minimum Inhibitory Concentration (MIC) which relates to sensitivity of the microorganisms in a planktonic state. Growth of any surviving microorganisms from the biofilm in a subsequent recovery step determines the Minimal Biofilm Eradication Concentration (MBEC) which relates to the sensitivity of the microorganisms growing as a biofilm. Enumeration of the surviving microorganisms in the recovery step determines the Minimum Biocidal Concentration (MBC).

Although zinc pyrithione is known as an excellent antidandruff component, there is a demand for an effort to reduce the blending amount without lowering the effects from the viewpoint of environmental pollution. Also, there is a demand for developing a technique that enables combining zinc pyrithione with cuprous oxide to be used as an antifouling component for a ship-bottom paint. Moreover, also as an antiseptic and anti-mold component for polymer materials, further enhancement of the antimicrobial activity of zinc pyrithione has been demanded.It has been elucidated that a new composite of the present invention obtained by treating an aqueous suspension or an aqueous paste containing zinc pyrithione or a zinc pyrithione / zinc oxide complex compound and ultrafine zinc oxide having an average particle diameter of 0.01 to 0.15 μM at pH 8 to 12 exerts an excellent physiologic / antibiotic activity such as an anti-dandruff and hair restoration effect and an underwater antifouling, antiseptic and anti-mold effect.
