The frequency and intensity of extreme heat in the environment have increased last decade. Extreme heating events (EHE) wide-ranging impacts on biological systems from molecular to community level. However, EHE been poorly studied pathogen–host systems. Here, we explore how affects interaction among insect hosts, Osmia cornifrons lignaria , a protozoan pathogen, Crithidia mellificae . We compar...

By extending a mechanistic model for the tick-borne pathogen systemic transmission with consideration of seasonal climate impacts, host movement as well co-feeding route, this paper proposes novel modeling framework describing spatial dynamics diseases. The net reproduction number tick growth and basic disease are derived, which predict global population transmission. Numerical simulations not ...

Shot hole disease of stone fruit trees, caused by Wilsonomyces carpophilus (Lév.) Adaskaveg, Ogawa & Butler(= Stigmina carpophila (Lév.) M.B. Ellis and Coryneum beijerinckii Oud.) is a serious disease of Prunus species in West Azerbaijan province. The pathogen was obtained from infected leaves, fruits and twigs of Prunus orchards during spring and summer of 2007. Samples were cultured on PDA, M...

In recent years, the spread of drug-resistant strains of Streptococcus pneumoniae, as the most common causes of bacterial respiratory infections, threatens public health. Therefore, the use of new antimicrobial medicines to inhibit this pathogen is an urgent demand. In this research project, the inhibitory effects of thirty recently synthesized compounds including thiazole, thiazolidine, imidaz...

Invasive soilborne plant pathogens cause substantial damage to crops and natural populations, but our understanding of how to prevent their epidemics or reduce their damage is limited. A key and experimentally-tested concept in the epidemiology of soilborne plant diseases is that of a threshold spacing between hosts below which epidemics (invasive spread) can occur. We extend this paradigm by e...
