Comparative virulence of Nosema ceranae and Nosema apis in individual European honey bees
Veterinary Parasitology, 2010Nosema 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.

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.

Nosema ceranae in drone honey bees (Apis mellifera)
Journal of Invertebrate Pathology, 2011Nosema 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.

Nosema ceranae is a relatively new and widespread parasite of the western honeybee Apis mellifera that provokes a new form of nosemosis. In comparison to Nosema apis, which has been infecting the honeybee for much longer, N. ceranae seems to have co-evolved less with this host, causing a more virulent disease. Given that N. apis and N.

Nosema ceranae in European honey bees (Apis mellifera)
Journal of Invertebrate Pathology, 2010Nosema 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.

The secondary structure of Nosema apis large subunit ribosomal RNA
Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression, 1998The microsporidia are a group of obligate intracellular eukaryotic parasites, that lack mitochondria. Their ribosomes show several prokaryote-like features. This paper presents the secondary structure of the large subunit ribosomal RNA (LSU rRNA) of the microsporidium Nosema apis. With its 2481 bases, it is the shortest known non-mitochondrial LSU rRNA.

Nosema ceranae infection is ubiquitous in western honey bees, Apis mellifera, in the United States and the pathogen has apparently replaced Nosema apis in colonies nationwide. Displacement of N. apis suggests that N. ceranae has competitive advantages but N. ceranae was significantly less infective and less virulent than N.

Influence of carbon dioxide on Nosema apis infection of honeybees (Apis mellifera)
Journal of Invertebrate Pathology, 2007Young workers of the honeybee Apis mellifera carnica were individually inoculated with Nosema apis spores subjected to carbon dioxide (CO(2)) treatment. The spores were kept in a CO(2) atmosphere for 30, 35 and 40 h. The course of the infection was evaluated on the basis of the survival rate of bee workers and the number of N.
