Nosema bombi, a microsporidian pathogen of the bumble bee Bombus terrestris (L.)

New Zealand Journal of Zoology, 1995
Abstract 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

Molecular characterization ofNosema bombi(Microsporidia: Nosematidae) and a note on its sites of infection inBombus terrestris(Hymenoptera: Apoidea)

Journal of Apicultural Research, 2001
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.

PCR reveals high prevalence of non/low sporulating Nosema bombi (microsporidia) infections in bumble bees (Bombus) in Northern Arizona

Journal of Invertebrate Pathology, 2014
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.

Identification of Nosema bombi Fantham and Porter 1914 (Microsporidia) in Bombus impatiens and Bombus sandersoni from Great Smoky Mountains National Park (USA)

Journal of Invertebrate Pathology, 2010
Ninety three bumble bees belonging to the genus Bombus, subgenus Pyrobombus (three Bombus vagans, seven Bombus bimaculatus, 17 B. sandersoni and 68 B. impatiens) from Great Smoky Mountains National Park were examined for microsporidia. Light microscopy of calcoflour and trichrome-stained smears, and PCR revealed infection with N.

The Status ofBombus occidentalisandB. moderatusin Alaska with Special Focus onNosema bombiIncidence

Northwest Science, 2012
Abstract 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

Complete rRNA Gene Sequences Reveal that the Microsporidium Nosema bombi Infects Diverse Bumblebee (Bombus spp.) Hosts and Contains Multiple Polymorphic Sites

Journal of Eukaryotic Microbiology, 2005
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.

Cross infectivity of Nosema bombi, transmission and impact on bumble bee colonies (Bombus terrestris)

2005
The project "Biodiversity, impact and control of microsporidia in bumble bee (bombus spp.) pollinators" (acronim "Pollinator parasites") within Key Action 5 of the Fifth framework R&D Programme Quality of LIfe and Management of Living Resources was initiated January 1, 2003 and terminates December 31, 2005.
