Equine EPCs are effectively labeled with QD, and QD concentrations up to 20 nM do not affect cell growth or function. The use of QD labeling with equine EPCs may help track engraftment of EPCs in clinical applications. Coagulase negative staphylococci (CNS) are the most prevalent pathogens isolated from intramammary infection in goats, with more than 15 different species being identified in goat milk. Unlike cows, the relationship between CNS infection, somatic cell count and milk loss in goats is less clear. The conflicting results between studies on CNS mastitis in goats may be explained by the variation between studies in regard to distribution of CNS species, varying pathogenicity between species, the presence of confounding factors affecting outcome measures, and variation between studies in regard to speciation methods. Phenotypic speciation was used in most studies; however genotyping is considered more reliable than phenotyping for identification of CNS species in goats. The objective of this study was to estimate the prevalence of species-specific CNS intramammary infections in a large dairy goat herd in Missouri.
