This test may be used to evaluate the adequacy of udder prep towel laundering procedures or storage conditions. Growth of more than 5 colonies of Environmental Streps, Staph species, or Coliforms indicates a likely risk for mastitis.
Results reported: cfu/in2 Staph species, Environmental Streps, Coliforms, Non-coliform Gram-negatives, Bacillus
This test is used to screen samples for the presence of Strep agalactiae, a contagious mastitis pathogen.
Results reported: Detected / Not detected / Inconclusive due to bacterial overgrowth
This test is used to screen samples for the presence of Staph aureus, a contagious mastitis pathogen.
Results reported: Detected / Not detected / Inconclusive due to bacterial overgrowth
This test is used to quantify the total number of aerobic bacteria, as an indicator of milk quality. It may be combined with other differential bacteria counts (See Milk Bacteria Troubleshooting Panel Option 1 and 2) ) to aid in investigation of elevated bulk milk bacteria counts.
Results reported: cfu/ml
This combination of tests is most often used to monitor the adequacy of pasteurization or heat treatment, storage conditions, and feeding equipment hygiene of waste milk or colostrum fed to calves. For more information, see the two Factsheets on Calf Feeding Systems. Results reported: cfu/ml SPC and Coliforms.
This test is used to screen samples for the presence of Prototheca, an incurable mastitis pathogen.
Results reported: Detected / Not detected / Inconclusive due to bacterial overgrowth
This test is used to quantify the number of bacteria that thrive at moderate temperatures, such as when milk cooling is inadequate, as an indicator of milk quality. It may be combined with other differential bacteria counts (See Milk Bacteria Troubleshooting Panel Option 1 and 2) ) to aid in investigation of elevated bulk milk bacteria counts.
Results reported: cfu/ml. Speciation available by request.
This test is used to screen samples for the presence of Mycoplasma species, a contagious and incurable mastitis pathogen.
If requested, the lab will pool individual samples (specify 5 or 10 per pool) for Mycoplasma screening. A pooling fee of $2.08 will be applied to each pool. When samples are pooled, the original samples will be kept refrigerated until the pooled result is available. Individual samples from a positive pool are automatically tested and charged the individual fee of $5.72 per sample in the pool.
This test is used to quantify the number of bacteria that survive pasteurization temperatures, as an indicator of milk quality. It may be combined with other differential bacteria counts (See Milk Bacteria Troubleshooting Panel Option 1 and 2) ) to aid in investigation of elevated bulk milk bacteria counts.
Results reported: cfu/ml. Speciation available by request.
Isolates in good condition will be identified with the MALDI-TOF or other techniques as appropriate.
Note: For clients using the MN Easy Culture System, we may be able to help with identification from high quality pictures emailed to the lab at no charge.
