JIS L Determination of antibacterial activity of antibacterial finished
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. Ecotoxicology – Test with algae, Daphnia magnaCrustaceans Palaemon spp. 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.
The choice of one or the other of the indicated inoculation methods depends on the properties of the surface of the textile product under test. All tests should include the test product with the antibacterial treatment, as well as a control tissue without antibacterial treatment supplied by the manufacturer.
This standard proposes three methods for inoculating the samples: For the counting of the bacteria in the test 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.
Type of bacteria used: Clinical Microbiology Rabies Laboratory authorized by the European Union HIV genotypic is to antiretrovirals Biocidal activities and toxicology with disinfectants 59 accredited tests Toxicology – Biological evaluation of medical devices; MPCA products 19 accredited tests Cosmetic Microbiology Laboratory of control authorized by AEMPS 8 accredited tests Neutralizing antibodies in human immunoglobulins 3 accredited tests News on viruses: The standard is applicable to all textile products, including cloth, wadding, thread and material for clothing, home furnishing and miscellaneous goods regardless of the type of antimicrobial agent used.

Staphylococcus aureus and Klebsiella pneumoniae. 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 If you not change browser settings, you agree to it.
For the method of inoculation by absorption, 0. This Standard specifies quantitative test methods for evaluating the antibacterial activity of bacteria on antibacterial finished textile products io nonwovens.

These methods should be applied at times 0 and after incubation from 18 to 24 hours. Facebook Linkedin Instagram Twitter Google. In order to improve the quality of life, some textile products are being treated with antimicrobials to prevent and protect against bacteria.
For the method of transfer inoculation, the same number of pieces of 3. 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.
Determination of antibacterial activity of textile products. Initially, the ISO standard was introduced for the qualitative evaluation of antibacterial activity, for which quantitative methods such as those included in uso standard had to be developed.

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