Dipartimento di Matematica, Università di Trento Via Sommarive 14 38050 Povo, Italy
Adv Exp Med Biol 673:32-50. 2010..These models do not yield universal predictions for patterns of parasite distributions; an analysis of the mechanisms of interaction in each specific system is necessary for that... 
The role of host population heterogeneity in the evolution of virulenceAndrea Pugliese
Dipartimento di Matematica, Universita di Trento, Via Sommarive 14, 38123, Povo TN, Italy
J Biol Dyn 5:104-19. 2011..Finally we clarify how contrasting results present in the literature are due to different modelling assumptions...- A simple model of pathogen-immune dynamics including specific and non-specific immunityAndrea Pugliese
Department of Mathematics, University of Trento, Via Sommarive 14, Trento 38050, Italy
Math Biosci 214:73-80. 2008..The model can also mimic some features of immune response after vaccination. This model could be a basis on which to build epidemic models including immunological features... - Effect of host populations on the intensity of ticks and the prevalence of tick-borne pathogens: how to interpret the results of deer exclosure experimentsA Pugliese
Department of Mathematics, University of Trento, Povo TN, Italy
Parasitology 135:1531-44. 2008..The density of infected questing nymphs inside small exclosures can be much higher, in our numerical example almost twice as large as that outside, leading to potential TBE infection risk hotspots... - Thresholds for macroparasite infectionsAndrea Pugliese
Dipartimento di Matematica, Universita di Trento, Via Sommarive 14, 38050 Povo TN, Italy
J Math Biol 49:83-110. 2004..The stability of equilibria is established by extending an abstract linearization principle and by analysing the spectra of appropriate operators... - On the evolutionary coexistence of parasite strainsAndrea Pugliese

J Math Biol 45:419-40. 2002..Finally, it is shown that the infected distribution converges, as time goes to infinity, to a Dirac measure at the value x(*), the equilibrium of a single-patch SIS model with contact rate equal to the sum of local and global contacts... - Epidemic patch models applied to pandemic influenza: contact matrix, stochasticity, robustness of predictionsAntonella Lunelli

Department of Mathematics, University of Trento, Povo, Italy
Math Med Biol 25:359-72. 2008..This finding stresses the need for carefully defining the structure of models in order to obtain results useful for policymakers in pandemic planning... - Thresholds for disease persistence in models for tick-borne infections including non-viraemic transmission, extended feeding and tick aggregationRoberto Rosa
Centre for Alpine Ecology, Viote del Monte Bondone, 38040 Trento, Italy
J Theor Biol 224:359-76. 2003..Finally, we incorporated the effects of tick aggregation on the hosts and correlation of tick stages and found that both had an important effect on infection persistence, if non-viraemic transmission occurred... - Temporal variation of Ixodes ricinus intensity on the rodent host Apodemus flavicollis in relation to local climate and host dynamicsRoberto Rosa
