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 ...

Effect of oxalic acid on Nosema ceranae infection

Research in Veterinary Science, 2015
Nosema ceranae is a honey bee pathogen parasitizing the ventricular epithelium and potentially causing colony death. The effect of 0.25 M oxalic acid solution administered to the bees in the form of sugar syrup was determined in laboratory and field trials.

Nosema ceranae, a new parasite in Thai honeybees

Journal of Invertebrate Pathology, 2011
Adult workers of Apis cerana, Apis florea and Apis mellifera from colonies heavily infected with Nosema ceranae were selected for molecular analyses of the parasite. PCR-specific 16S rRNA primers were designed, cloned, sequenced and compared to GenBank entries. The sequenced products corresponded to N. ceranae. We then infected A.

Dicer regulates Nosema ceranae proliferation in honeybees

Insect Molecular Biology, 2018
Abstract Nosema ceranae is a microsporidian parasite that infects the honeybee midgut epithelium. The protein‐coding gene Dicer is lost in most microsporidian genomes but is present in N. ceranae .

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.

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.

Kontroversen über Nosema ceranae (Mikrosporidien)

2022
Honey bees are likely to be the best-known bees, but they represent only a fraction of the world's existing bee species. The vast majority of bees is not kept by humans but considered as wildlife species. For these wild bees, according to current reports, declines in number and diversity can be observed.
