Replacement AUP-3 plates for the Mastaplex system. Pack of 10. One plate is used for each sample of milk. Quantity discounts for bulk orders. If the milk sample contains mastitis causing bacteria then Mastatest delivers critical information to guide antibiotic treatment choice. Mastatest relates the antibiotic sensitivity of the mastitis causative organism to three widely used antibiotic groups. From this information, an appropriate antibiotic can be selected for the treatment of mastitis. The test identifies any of the four main types of mastitis causing organisms: Streptococcus uberis, Staphylococcus aureus, coagulase negative Staphylococcus and Coliform (gram negative) bacteria (such as E. Coli, Klebsiella). If you wish to order multiple units of this product – as you select 2, 3, 4 etc – you are ordering 20, 30, 40 plates respectively.
