Bumblebees are of profound ecological importance because of the pollination services they provide in natural and agricultural ecosystems. Any decline of these pollinators is therefore of great concern for ecosystem functioning. Increased parasite pressures have been discussed as a major factor for the loss of pollinators.

A field experiment on the effect of Nosema bombi in colonies of the bumblebee Bombus terrestris
Ecological Entomology, 2008Abstract 1. Nosema bombi is a microsporidian parasite of bumblebees that is of potentially great ecological and economic importance. Nosema bombi has been shown to have detrimental fitness effects on the bumblebee

Nosema bombi, a microsporidian pathogen of the bumble bee Bombus terrestris (L.)
New Zealand Journal of Zoology, 1995Abstract The developmental cycle and morphology of a microsporidian pathogen Nosema bombi Fantham & Porter 1914, of the bumble bee, Bombus terrestris, are described. In experimentally infected bees, spherical meronts were the first

About 20% of bumble bee species are in decline in North America, and the microsporidian pathogen, Nosema bombi, has been correlated with these declines. We conducted a comprehensive survey of N. bombi infections in the bumble bee communities throughout the flight season along an elevation gradient in Northern Arizona.

SUMMARYInvestigations of queen, worker and male bumble bees (Bombus terrestris) showed that all individuals became infected with Nosema bombi. Infections were found in Malpighian tubules, thorax muscles, fat body tissue and nerve tissue, including the brain.

The Status ofBombus occidentalisandB. moderatusin Alaska with Special Focus onNosema bombiIncidence
Northwest Science, 2012Abstract Four North American bumble bee species in the subgenus Bombus sensu stricto, including Bombus occidentalis (Hymenoptera: Apidae), are experiencing dramatic declines in population abundance, geographic range and genetic diversity. The prevailing hypothesis concerning their decline is the transmission of the intracellular fungal pathogen. Nosema

Abstract. Characterisation of microsporidian species and differentiation among genetic variants of the same species has typically relied on ribosomal RNA (rRNA) gene sequences. We characterised the entire rRNA gene of a microsporidium from 11 isolates representing eight different European bumblebee (Bombus) species.
