Article Synopsis
- The study focused on mapping dengue vectors in Ouro Preto and Ouro Branco, Brazil, by using ovitraps in 32 public schools over an 18-month period.
- A total of 1,945 eggs were collected, with the Ovitrap Positivity Index ranging from 0 to 28.13% and the Eggs Density Index from 0 to 59.9%, indicating variable mosquito presence.
- The predominant species identified was Aedes aegypti, comprising 84.9% of the larvae, and dengue virus was detected in four out of 54 pools, suggesting the potential for vertical transmission.
A rapid method for the detection and quantification of the adulteration of milk powder by the addition of whey was assessed by measuring glycomacropeptide protein using mid-infrared spectroscopy (MIR). Fluid milk samples were dried and then spiked with different concentrations of GMP and whey. Calibration models were developed using multivariate techniques, from spectral data.
