The SBA booklets have been written by teams of subject specialists to assist teachers to adapt teaching and learning methods to improve learner performance and the quality and management of SBA. Assessment of and for learning is an ongoing process that develops from the interaction of teaching, learning and assessment. To improve learner performance, assessment needs to support and drive focused, effective teaching.

Several bacterial pathogens that infect cows, including Mycoplasma bovis and Salmonella enterica ssp. Milk acidification lowers the milk pH so that it is unsuitable for bacterial growth and survival. The objectives of this study were to 1 determine the growth of M.

For the first objective, 3 treatments and a positive control were prepared in 10 mL of milk and broth, respectively, and inoculated with M. Aliquots were taken at 4, 8, 24, 28, 32, 48, 52, and 56 h after inoculation and transferred onto agar medium in triplicate following a fold dilution series in sterile phosphate-buffered saline.

All plates were incubated and colonies counted. For the second objective, 4 treatments and a positive control were prepared with mL of milk and inoculated with M.

With the use of Salstop, treatments were adjusted to an approximate pH of 6, 5, 4, or 3. The positive control was left untreated.

At 1, 2, 4, 6, 8, and 24 h after treatment, triplicate aliquots were taken, the pH measured, and then the aliquots were transferred onto agar medium and into broth for enrichment. Following incubation, agar colonies were counted, while broths were plated and incubated prior to colonies being counted.

All trials were repeated. Mycoplasma bovis did not grow in milk, but Salmonella Dublin proliferated. The pH of all acidification treatments remained stable for 24 h.

Following 24 h of exposure to pH 6 M. No viable Salmonella Dublin organisms were detected at 2 and 6 h of exposure to pH 3.

Salmonella Dublin remained viable following 24 h of exposure to pH 5 and 6. These results demonstrate that milk acidification using Salstop is effective at eliminating viable M. Previous article in issue.Congressional Research Service Reports.
