Quantifying Behavioral Changes in Territorial Animals Caused by Sudden Population Declines

Behavioral and Personality Changes Caused by Toxoplasma: Imagination or Reality

Introduction: This note addresses the scientific study of behavioral changes caused by Toxoplasma. About a third of the world's population is infected with the chronic form of the parasite, which is usually asymptomatic and causes severe symptoms only in the presence of the parasite in the eye and nervous system. The study of behavioral changes caused by this parasite has begun since the 1980s ...

Population Dynamics and Epidemiology of Territorial Animals

Population-level HIV declines and behavioral risk avoidance in Uganda.

Uganda provides the clearest example that human immunodeficiency virus (HIV) is preventable if populations are mobilized to avoid risk. Despite limited resources, Uganda has shown a 70% decline in HIV prevalence since the early 1990s, linked to a 60% reduction in casual sex. The response in Uganda appears to be distinctively associated with communication about acquired immunodeficiency syndrome...

Encounter times in overlapping domains: application to epidemic spread in a population of territorial animals.

We develop an analytical method to calculate encounter times of two random walkers in one dimension when each individual is segregated in its own spatial domain and shares with its neighbor only a fraction of the available space, finding very good agreement with numerically exact calculations. We model a population of susceptible and infected territorial individuals with this spatial arrangemen...

Quantifying changes in incidences of nosocomial bacteraemia caused by antibiotic-susceptible and antibiotic-resistant pathogens.

OBJECTIVES The aim of this study was to determine, over time, changes in annual trends of nosocomial bacteraemia (NB) and to quantify pathogen-specific changes and emergence of antibiotic resistance. METHODS A retrospective cohort study in a 997 bed tertiary care centre in the Netherlands was performed. All adult patients (> or =18 years old) admitted for >48 h between 1 January 1996 and 31 D...
