Última Measuring of Mycobacterium tuberculosis growth: a correlation of the optical measurements with colony forming units BJM Peñuelas-Urquides,Katia; Villarreal-Treviño,Licet; Silva-Ramírez,Beatriz; Rivadeneyra-Espinoza,Liliana; Said-Fernández,Salvador; León,Mario Bermúdez de. The quantification of colony forming units (cfu), turbidity, and optical density at 600 nm (OD600) measurements were used to evaluate Mycobacterium tuberculosis growth. Turbidity and OD600 measurements displayed similar growth curves, while cfu quantification showed a continuous growth curve. We determined the cfu equivalents to McFarland and OD600 units.

Production information of 29 milk producers in the southern region of Chile was studied with the objective of characterizing and classifying different dairy production systems, evaluating various associations between quantitative and qualitative studied variables and analyzing the effect of the production system and the quality of bovine milk according to the month of the year that it was processed. The classification of production groups was based on the implementation of the exploratory multivariate technique, main components analysis and conglomerates or cluster analysis. The applied statistical model was: y ijk = µ + Mi + SPj + MSPij + e ijk, where y ijk=dependent variables (fat, protein, count of somatic cells and colony forming units); µ=general...
