some results of the application of streptococcus agalactiae (cornell 48 strain) to the bovine teat canal by means of the hadley-wisconsin swab technique. 195313067637
risk factors associated with short-term post-treatment outcomes of clinical mastitis.the objectives of this study were to characterize 60-d outcomes after treatment of mild (abnormal milk) and moderate (abnormal milk and abnormal udder) cases of clinical mastitis (cm) occurring in a single quarter of cows on wisconsin farms (n=4) and to determine risk factors associated with those outcomes. duplicate milk samples were collected from the affected quarter of each cow for microbiological analysis at the onset of cm (pre) and 21 d later (post). cows were treated only in the affected ...201121700025
results of milk samples submitted for microbiological examination in wisconsin from 1994 to 2001.the objective of this study was to examine the characteristics of milk samples submitted for microbiological examination at the wisconsin veterinary diagnostic laboratory between 1994 and 2001. results (n = 83,650) of microbiological testing of milk samples (n = 77,172) submitted to the wisconsin veterinary diagnostic laboratory from january 1994 until june 2001 were analyzed. submissions included milk samples obtained from cases of clinical and subclinical mastitis as well as samples obtained f ...200314672176
field validation of a milk line sampling device for monitoring milk quality and udder health.the objective of this study was to investigate the ability of a milk line sampling device to obtain a representative sample by comparing scc and bacterial culture results between milk line and bulk tank samples for milk harvested from the same group of cows at the same milking. a total of 42 paired milk line and bulk tank samples were collected at separate milking events from 21 different herds. concordance correlation coefficients showed a high level of agreement between the two sample types, w ...200212146478
the individual cow as a factor in streptococcus agalactiae infection artificially induced by means of the hadley-wisconsin swab technique. 195413150771
variation in wisconsin mastitis test scores of bucket milk samples and relationship to bacterial infections.sources of variation in the wisconsin mastitis test were studied in 4739 bucket milk samples from 111 cows in one herd during 103 days. quarters of cows were classified infected or uninfected through bacteriologic assays of quarter milk samples. quarters were uninfected in 70.4% of the cow-quarter-days and infected with staphylococcus aureus and streptococcus agalactiae in 1.4 and .9% of the quarter samples. scores of all cow-days averaged 8.5. wisconsin mastitis test scores of cow-days having n ...19817264013
