Pathogenesis of feline enteric coronavirus infection. [PDF]
, 2008 Fifty-one specific pathogen-free (SPF) cats 10 weeks to 13 years of age were infected with a cat-to-cat fecal-oral passed strain of feline enteric coronavirus (FECV). Clinical signs ranged from unapparent to a mild and self-limiting diarrhea. Twenty-nine

Does host contact structure reduce pathogen diversity? [PDF]
arXiv, 2005 We investigate the dynamics of a simple epidemiological model for the invasion by a pathogen strain of a population where another strain circulates. We assume that reinfection by the same strain is possible but occurs at a reduced rate due to acquired immunity.

Maintenance of diversity in a hierarchical host-parasite model with balancing selection and reinfection [PDF]
arXiv, 2018 Inspired by DNA data of the human cytomegalovirus we propose a model of a two-type parasite population distributed over its hosts. The parasite is capable to persist in its host till the host dies, and to reinfect other hosts. To maintain type diversity within a host, balancing selection is assumed. For a suitable parameter regime we show that in the

A two-patch epidemic model with nonlinear reinfection [PDF]
arXiv, 2019 The propagation of infectious diseases and its impact on individuals play a major role in disease dynamics, and it is important to incorporate population heterogeneity into efforts to study diseases. As a simplistic but illustrative example, we examine interactions between urban and rural populations in the dynamics of disease spreading.

Limited asymptomatic carriage of Pneumocystis jiroveci in human immunodeficiency virus-infected patients [PDF]
, 2003 Forty-seven bronchoalveolar lavage fluid samples from 16 human immunodeficiency virus (HIV)-infected patients were used to test the latency model of Pneumocystis infection in the human host.

The Second Phase Transition of the Contact Process on a Random Regular Graph [PDF]
arXivThe regular tree corresponds to the random regular graph as its local limit. For this reason the famous double phase transition of the contact process on regular tree has been seen to correspond to a phase transition on the large random regular graph, at least at the first critical value. In this article, we find a phase transition on that large finite

A Bayesian Framework for Parameter Estimation in Dynamical Models with Applications to Forecasting [PDF]
, 2009 Mathematical models in Biology are powerful tools for the study and exploration of complex dynamics. Nevertheless, bringing theoretical results to an agreement with experimental observations involves acknowledging a great deal of uncertainty intrinsic to

Role of Mobility and Health Disparities on the Transmission Dynamics of Tuberculosis [PDF]
arXiv, 2016 The transmission dynamics of Tuberculosis (TB) involve complex epidemiological and socio-economical interactions between individuals living in highly distinct regional conditions. The level of exogenous reinfection and first time infection rates within high-incidence settings may influence the impact of control programs on TB prevalence.

The Role of Reinfection and Partner Notification in the Efficacy of Chlamydia Screening Programs [PDF]
, 2017 Repeated Chlamydia trachomatis infections after treatment are common. One reason is reinfection from untreated partners in ongoing sexual partnerships. Mathematical models that are used to predict the impact of screening on reducing chlamydia prevalence ...

Optimal protection and vaccination against epidemics with reinfection risk [PDF]
arXivWe consider the problem of the optimal allocation of vaccination and protection measures for the Susceptible-Infected-Recovered-Infected (SIRI) epidemiological model, which generalizes the classical Susceptible-Infected-Recovered (SIR) and Susceptible-Infected-Susceptible (SIS) epidemiological models by allowing for reinfection.
