Parasitism, the diversity of life, and paleoparasitology
Memorias do Instituto Oswaldo Cruz, 2003 The parasite-host-environment system is dynamic, with several points of equilibrium. This makes it difficult to trace the thresholds between benefit and damage, and therefore, the definitions of commensalism, mutualism, and symbiosis become worthless ...

Microbiology Spectrum, 2016 ABSTRACT Parasites are an important cause of human disease worldwide. The clinical severity and outcome of parasitic disease is often dependent on the immune status of the host. Specific parasitic diseases discussed in this chapter are amebiasis, giardiasis, cryptosporidiosis, cyclosporiasis, cystoisosporiasis, microsporidosis, granulomatous ...

Effects of Aluminum Foil Mulch on Parasitism and Fecundity of Apterous \u3ci\u3eMyzus Persicae\u3c/i\u3e (Homoptera: Aphididae) [PDF]
, 2017 Chinese cabbage plants grown in flats containing either aluminum foil mulch or no mulch cover were uniformly infested with a single apterous adult Myzus persicae (Sulzer) and exposed in a greenhouse to a free-flying population of the parasite Aphidius ...

British Medical Bulletin, 2000 Ill health related to food-borne infection transcends all geographical, political and cultural boundaries. The incidence of food-borne diseases continues to adversely affect the health and productivity of populations in most countries, especially non-industrialised ones.

Apparent competition drives community-wide parasitism rates and changes in host abundance across ecosystem boundaries [PDF]
, 2016 Species have strong indirect effects on others, and predicting these effects is a central challenge in ecology. Prey species sharing an enemy (predator or parasitoid) can be linked by apparent competition, but it is unknown whether this process is strong

European Journal of Entomology, 2006 The horse chestnut leaf miner, Cameraria ohridella Deschka & Dimić, is a species of unknown origin that recently invaded most of Europe, causing serious damage to horse chestnut trees, Aesculus hippocastanum. Parasitism was studied over a period of three
