Resource quality differentially impacts Daphnia interactions with two parasites

Ecosphere, Volume 16, Issue 3, March 2025.
Abstract Resource quality can have conflicting effects on host–parasite interactions; for example, higher resource quality might increase host investment in immune function, or conversely, might permit greater parasite reproduction. Thus, anticipating the impact of changing resource quality on host–parasite interactions is challenging, especially ...

Transfer and Development of Pasteuria penetrans.

Journal of nematology, 2012
Pasteuria penetrans isolate P-20 has been attributed as the cause of soil suppressiveness to peanut root-knot nematode in Florida. In this study, P. penetrans was transferred from a suppressive site to a new site and established by growing susceptible hosts to the peanut root-knot nematode during both summer and winter seasons. When two soil fumigants,

Acclimation temperature and parasite infection drive metabolic changes in a freshwater fish at different biological scales

Functional Ecology, Volume 39, Issue 2, Page 350-361, February 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Environmental stressors such as elevated temperature and parasite infection can impact individual energy metabolism. However, organismal responses to co‐occurring stressors and their effects across biological scales remain unexplored despite the importance of ...

A common multi-host parasite shows genetic structuring at the host species and population levels

Parasitology
Although individual parasite species commonly infect many populations across physical space as well as multiple host species, the extent to which parasites traverse physical and phylogenetic distances is unclear.

Occurrence of Pasteuria spp. in Florida.

Journal of nematology, 2011
Two years of data collected from the Florida Nematode Assay Laboratory of the Florida Cooperative Extension Service and 4 years of data from the Florida Department of Agriculture and Consumer Services, Division of Plant Industry, were compiled to find out the distribution of Pasteuria spp. on nematodes in Florida soils.

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 21: Suitability of taxonomic units notified to EFSA until September 2024

EFSA Journal, Volume 23, Issue 1, January 2025.
Abstract The qualified presumption of safety (QPS) process was developed to provide a safety assessment approach for microorganisms intended for use in food or feed chains. In the period covered by this Statement, no new information was found that would change the status of previously recommended QPS taxonomic units (TUs).

Minimal Growth Temperature of Pasteuria penetrans.

Journal of nematology, 2011
Pasteuria penetrans is an obligate, mycelial, and endospore-forming bacterial parasite of Meloidogyne spp. with promise for the management of root-knot nematodes. Our objective was to use regression analysis of developmental time (days) to various temperatures to determine the minimal temperature for growth and development of P.

Parasite transmission stage abundance varies in lakes over time and space

Limnology and Oceanography, Volume 69, Issue 9, Page 2167-2179, September 2024.
Abstract Environmentally transmitted parasites produce transmission stages that can remain viable and infective for extended periods of time in the environment where susceptible hosts may encounter them. Although many parasites have this mode of transmission, the abundance and distribution of environmental transmission stages have largely been ...

Interactions between microsporidia and other members of the microbiome

Journal of Eukaryotic Microbiology, Volume 71, Issue 5, September/October 2024.
Abstract The microbiome is the collection of microbes that are associated with a host. Microsporidia are intracellular eukaryotic parasites that can infect most types of animals. In the last decade, there has been much progress to define the relationship between microsporidia and the microbiome.
