HOST-PARASITE RELATIONS IN MOUSE TYPHOID [PDF]

The Journal of Experimental Medicine, 1966
The development of acquired resistance to Salmonella typhimurium has been studied in mice infected intravenously with small numbers of streptomycin-sensitive or streptomycin-resistant organisms. By the 14th day of a primary infection the mouse develops a mechanism capable of destroying completely a super infecting dose of organisms, but is unable to ...

Diversity–disease relationships in natural microscopic nematode communities [PDF]

Royal Society Open Science
Host diversity can affect parasite prevalence, a phenomenon widely studied in macroscopic organisms. However, data from microscopic communities are lacking, despite their essential role in ecosystem functioning and the unique experimental opportunities ...

Effects of Organic Xenobiotics on Tenebrio molitor Larvae and Their Parasite Gregarina polymorpha [PDF]

Biology
Environmental contamination with xenobiotics affects organisms and the symbiotic relations between them. A convenient object to study relationships between parasites and their hosts is the host–parasite system “Tenebrio molitor Linnaeus, 1758 (Coleoptera,

Weighing the predictors: host traits and coinfecting species both explain variation in parasitism of Rock Ptarmigan

Ecosphere, 2021
Testing hypotheses in ecological and evolutionary parasitology can require testing whether host traits or coinfecting parasites explain variation in parasitism by focal species.

Adaptation of the Relationship in the "Parasite–Host" System with Parasitism Paramphistomum сervi in the Small Intestine of Sheeps

Российский паразитологический журнал, 2020
The purpose of the research is studying microstructural changes in the process of adaptation of components during the formation of the “parasite–host” system by the example of Paramphistomum cervi (Zeder, 1790) parasitizing in the small intestine of ...

Diversity and host associations of Myrsidea chewing lice (Phthiraptera: Menoponidae) in the tropical rainforest of Malaysian Borneo

International Journal for Parasitology: Parasites and Wildlife, 2020
The tropical rainforests of Sundaland are a global biodiversity hotspot increasingly threatened by human activities. While parasitic insects are an important component of the ecosystem, their diversity and parasite-host relations are poorly understood in

Trematode diversity reflecting the community structure of Danish freshwater systems: molecular clues

Parasites & Vectors, 2021
Background Digenean trematodes are parasitic platyhelminths that use several hosts in their life cycles and are thereby embedded in various ecosystems affected by local environmental conditions.

Environmental temperature affects prevalence of blood parasites of birds on an elevation gradient: implications for disease in a warming climate. [PDF]

PLoS ONE, 2012
BACKGROUND: The rising global temperature is predicted to expand the distribution of vector-borne diseases both in latitude and altitude. Many host communities could be affected by increased prevalence of disease, heightening the risk of extinction for ...
