Nosema ceranae, a new microsporidian parasite in honeybees in Europe

Journal of Invertebrate Pathology, 2006
Twelve samples of adult honey bees from different regions of Spain from colonies with clear signs of population depletion, positive to microsporidian spores using light microscopy (1% of total positive samples analysed), were selected for molecular diagnosis. PCR specific primers for a region of the 16S rRNA gene of Microsporidia were developed and the

How natural infection by Nosema ceranae causes honeybee colony collapse

Environmental Microbiology, 2008
Summary In recent years, honeybees ( Apis mellifera ) have been strangely disappearing from their hives, and strong colonies have suddenly become weak and died. The precise aetiology underlying the disappearance of the bees remains a mystery. However, during the same period,

Viability and infectivity of fresh and cryopreserved Nosema ceranae spores

Journal of Microbiological Methods, 2016
The microsporidium fungus Nosema ceranae is an intracellular parasite that infects the midgut of the honey bee, Apis mellifera. A major limitation of research on N. ceranae is that the fungus is non-culturable and thus studying it depends on the seasonal availability of Nosema spores.

Presence of Nosema ceranae in honeybees (Apis mellifera) in Uruguay

Journal of Invertebrate Pathology, 2009
The microsporidium Nosema ceranae is an emergent pathogen of European honeybees Apis mellifera. Using a PCR-RFLP diagnosis, 29 samples of infected honeybees obtained in 2007-2008 (N=26), 2004 (N=2) and before 1990 (N=1) were analyzed for the presence of Nosema apis and N. ceranae. Only N.

Low natural levels of Nosema ceranae in Apis mellifera queens

Journal of Invertebrate Pathology, 2012
Queens are the primary female reproductive individuals in honey bee colonies and, while they are generally free from Nosema ceranae infection, they are nevertheless susceptible. We sought to determine whether queens are naturally infected by N. ceranae, as these infections could be a factor in the rapid spread of this parasite.

Nosema ceranae an emergent pathogen of Apis mellifera in Chile

Parasitology Research, 2012
The microsporidian Nosema apis and Nosema ceranae have been associated with colony disorders of Apis mellifera and Apis cerana, respectively. N. apis is endemic in South America. Recently, N. ceranae has been detected in Brazil, Uruguay and Argentina. No report of its presence, distribution and prevalence in Chile is available.

Detection of Nosema ceranae in honey bees from Croatia

Journal of Apicultural Research, 2010
Nosema ceranae has not been detected in Croatia to date, but we have suspected in pure or mixed infections with Nosema apis, because of high procentage of Nosema infections being found during summer, and, because N. ceranae has been diagnosed in some neighbouring contries. The aim of this research was to determine the presence of N. ceranae in Croatia,

Experimental infection of Apis mellifera honeybees with Nosema ceranae (Microsporidia)

Journal of Invertebrate Pathology, 2007
In this report, an experimental infection of Apis mellifera by Nosema ceranae, a newly reported microsporidian in this host is described. Nosema free honeybees were inoculated with 125,000 N. ceranae spores, isolated from heavily infected bees. The parasite species was identified by amplification and sequencing the SSUrRNA gene of the administered ...
