Most persons were infested with only one tick but some troops had multiple infestations. Local skin reactions to tick-bites were frequent; they usually developed 24-48 h after removal of th...

Active Shape Models (ASM) are applied to the attachment hooks of several species of Gyrodactylus, including the notifiable pathogen G. salaris, to assign each species to its true species type. ASM is used as a feature extraction tool to select information from hook images that can be used as input data into trained classifiers. Linear (i.e. LDA and K-NN) and non-linear (i.e. MLP and SVM) models...
