How diseases affect symbiotic communities

Mathematical Biosciences
E Venturino

Abstract

Examples of species living in symbiotic communities are well known among biologists. In this study we extend our previous analysis of predator-prey or competing models subject to a disease spreading among one of the species to populations mutually benefiting from interactions. We assume that one of the species is subject to a disease which cannot cross the species barrier and investigate the behavior of such a community. Our findings indicate that there are parameter ranges for which an interesting phenomenon occurs. Namely, the equilibrium shifts to a higher value. That is, the disease seems to have a positive effect on the environment as also field experiments show.

Botulism (ASM)

Botulism is a rare but serious paralytic illness caused by a nerve toxin that is produced by the bacterium clostridium botulinum. Discover the latest research on botulism here.

Aspergillosis

Aspergillosis is the name given to a wide variety of diseases caused by infection by fungi of the genus Aspergillus. Aspergillosis occurs in chronic or acute forms which are clinically very distinct. Most cases of acute aspergillosis occur in patients with severely compromised immune systems. Chronic colonization or infection can cause complications in people with underlying respiratory illnesses. Discover the latest research on aspergillosis here.
