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.

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 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

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

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.

Nosema ceranae in drone honey bees (Apis mellifera)

Journal of Invertebrate Pathology, 2011
Nosema ceranae is a microsporidian intracellular parasite of honey bees, Apis mellifera. Previously Nosema apis was thought to be the only cause of nosemosis, but it has recently been proposed that N. ceranae is displacing N. apis. The rapid spread of N. ceranae could be due to additional transmission mechanisms, as well as higher infectivity.

First molecular detection of Nosema ceranae in Azerbaijan

Journal of Apicultural Research, 2019
Nosemosis is an important adult honey bee disease and causes economic losses worldwide. The aim of this study was to determine the Nosema species in honey bees (Apis mellifera) of Azerbaijan.

Nosema ceranae infection intensity highly correlates with temperature

Journal of Invertebrate Pathology, 2012
Nosema ceranae, a microsporidian entomopathogen, was first reported from honey bees, Apis mellifera, in 2005 in Taiwan (Huang et al., 2007) and has become a major concern in apiculture worldwide. In Taiwan, we found one infection peak for N. ceranae during the winter months, compared to two peaks in spring and fall reported in 1980 for Nosema apis.

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.
