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.

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.

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.

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

Nosema ceranae disease treatment with Nozevit

2010
Nosema ceranae disease is a microsporidian parasitic disease that affects adult honeybees. There is a big problem in controlling nosemosis, especially caused with N. ceranae because of its asymptomatic duration and profibited use of antibiotics and Fumagillin in the treatment of apian diseases in Croatia, as well as in Eu regulations. Therefore, use of

Infections of Nosema ceranae in four different honeybee species

Journal of Invertebrate Pathology, 2010
The microsporidium Nosema ceranae is detected in honeybees in Thailand for the first time. This endoparasite has recently been reported to infect most Apis mellifera honeybee colonies in Europe, the US, and parts of Asia, and is suspected to have displaced the endemic endoparasite species, Nosema apis, from the western A. mellifera.
