Nosema ceranae in European honey bees (Apis mellifera)

Journal of Invertebrate Pathology, 2010
Nosema ceranae is a microsporidian parasite described from the Asian honey bee, Apis cerana. The parasite is cross-infective with the European honey bee, Apis mellifera. It is not known when or where N. ceranae first infected European bees, but N. ceranae has probably been infecting European bees for at least two decades. N.

Improving molecular discrimination of Nosema apis and Nosema ceranae

Journal of Invertebrate Pathology, 2013
Nosema apis and Nosema ceranae are the causative agents of nosemosis, a contagious honeybee disease that weakens bee colonies. The species are discriminated through several PCR-based methods including a multiplex PCR recommended by the World Organization for Animal Health (OIE).

Comparative development and tissue tropism of Nosema apis and Nosema ceranae

Journal of Invertebrate Pathology, 2013
The two etiological agents of nosema disease in honey bees, Nosema apis and Nosema ceranae (Microsporidia: Nosematidae), reproduce in the midgut tissues of the host. N. apis is tissue specific but the development and tissue tropism of N. ceranae is not well understood.

Asymmetrical coexistence of Nosema ceranae and Nosema apis in honey bees

Journal of Invertebrate Pathology, 2009
Globalization has provided opportunities for parasites/pathogens to cross geographic boundaries and expand to new hosts. Recent studies showed that Nosema ceranae, originally considered a microsporidian parasite of Eastern honey bees, Apis cerana, is a disease agent of nosemosis in European honey bees, Apis mellifera, along with the resident species ...

Comparative virulence and competition between Nosema apis and Nosema ceranae in honey bees (Apis mellifera)

Journal of Invertebrate Pathology, 2015
Honey bees (Apis mellifera) are infected by two species of microsporidia: Nosema apis and Nosemaceranae. Epidemiological evidence indicates that N. ceranae may be replacing N. apis globally in A. mellifera populations, suggesting a potential competitive advantage of N. ceranae.

The microsporidian parasites Nosema ceranae and Nosema apis are widespread in honeybee (Apis mellifera) colonies across Scotland

Parasitology Research, 2012
Nosema ceranae is spreading into areas where Nosema apis already exists. N. ceranae has been reported to cause an asymptomatic infection that may lead, ultimately, to colony collapse. It is thought that there may be a temperature barrier to its infiltration into countries in colder climates.

Comparative virulence of Nosema ceranae and Nosema apis in individual European honey bees

Veterinary Parasitology, 2010
Nosema apis and Nosema ceranae are intracellular microsporidian parasites infecting the midgut epithelial cells of adult honey bees. N. ceranae was considered to be restricted to the Asian honey bee, Apis cerana, but is nowadays a parasite found also in the European honey bee (Apis mellifera) across most of the world.

Microsporidia infecting Apis mellifera : coexistence or competition. Is Nosema ceranae replacing Nosema apis ?

Environmental Microbiology, 2011
Summary Nosema ceranae has been suggested to be replacing Nosema apis in some populations of Apis mellifera honeybees.

Molecular Identification of Nosema ceranae and Nosema apis in Native Bulgarian Honey Bee (Apis mellifera rodopica)

Journal of Veterinary Science & Medical Diagnosis, 2015
Molecular Identification of Nosema ceranae and Nosema apis in Native Bulgarian Honey Bee (Apis mellifera rodopica) The aim of current study is to investigate the presence of two main microsporidian parasites N. apis and N. ceranae in Bulgarian local honey bee. The discrimination among two Nosema species was carried out on 18 individual samples.

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.
