This implies the use of methods isoo corroborate the existence of antibacterial activity, applicable to textile products with antibacterial finishes, including izo, napas, threads and other materials for the manufacture of garments, bedding, domestic furniture and miscellaneous items, whatever the type of izo agent used organic, inorganic, natural or synthetic or any of the methods used by manufacturers for their incorporation into the textile product.

Inoculated samples are incubated for 18 hrs testing is run in triplicate for each organism and time point the bacteriostatic activity value and bactericidal activity value are calculated as log reductions JIS-L and ISO are very similar to AATCC The client must choose, if desired, one or the other of the three inoculation methods indicated, as well as between the two detection methods indicated.

This procedure must be carried out with bacterial species: Pseudomonas aeruginosa, Escherichia coli and methicillin resistant Staphylococcus aureus Test samples are run in triplicate and are sterilized by high pressure steam in the autoclave.

For the counting of the bacteria in the isp products and in the controls, the conventional method of counting CFU colony forming units or the ATP-luminescence measuring can be used measuring the amount of ATP in bacterial cells, expressed in moles of ATP-adenosine triphosphate.

Determination of antibacterial activity of textile products. Concentrations for all organisms and methods are done using automated equipment; as in Tempo Filler and Reader from BioMerieux and the Autoplater and Q-count from Spiral Biotech. These methods should be applied at times 0 and after incubation from 18 to 24 hours.

JIS L /ISO – Microbe Investigations (MIS)

This standard proposes three methods for inoculating the samples: In order to consider the result as significant, a reduction in the number of bacteria between 2 and 3 logarithms must be obtained, considering a powerful activity if the value of the reduction is greater than 3 logarithms.

Initially, the ISO standard was introduced for the qualitative evaluation of antibacterial activity, 02743 which quantitative methods such as those included in this standard had to be developed. The choice of one or the io of the indicated inoculation methods depends on the properties of the surface of the textile product under test.
