A total of 61 subclinical mastitis isolates of Staphylococci were evaluated for oxacillin, erythromycin, tetracycline, nitrocefin, and cefoxitin using the Kirby-Bauer disc diffusion method. The same isolates were also subjected to the multiplex PCR technique to detect mecA, femA and ermA, ermC, tetK, and tetM genes. Of the isolates, (Staphylococcus aureus, n=34 and coagulase negative Staphylococcus (CoNS), n=27) 26, 29, and 8 were resistant to erythromycin, tetracycline, and oxacillin, respectively in phenotypical evaluation. The genotypical evaluation indicated that of the strains, 34 carried erm genes in erythromycin-resistant strains and 10 carried tet genes in tetracycline-resistant strains. Agreement rates between genotypic and phenotypic evaluation for e...

These combinations included iodine, sodium chlorite, lactic acid, and orthophosphoric acid. Visual assessments of teat skin and teat ends were made on the teats of 101 cows. Teat skin thickness, teat end thickness, and transepidermal water loss were assessed for the teats of 50 cows. The interaction of predip and postdip had no effect on teat condition. Postdip had a significant effect on transepidermal water loss, visual teat skin condition, and visual teat end condition. The 1% iodine postdip was associated with the poorest teat skin condition.
