Intracellular stages in the life cycle of the microsporidian Nosema apis

Journal of Invertebrate Pathology, 1969
Abstract The intracellular stages of the microsporidian Nosema apis are described, and photomicrographs are presented as an aid for the identification of this parasite of the honey bee, Apis mellifera.

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 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.

Influence of carbon dioxide on Nosema apis infection of honeybees (Apis mellifera)

Journal of Invertebrate Pathology, 2007
Young 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.

Fine structure of the developing spore of Nosema apis zander

Zeitschrift f�r Zellforschung und mikroskopische Anatomie, 1973
The mature spore possesses a thick spore coat and a particle-bearing spore membrane. The highly laminated polaroplast membranes are located at the anterior pole of the spore. Close to its base, the polar filament is surrounded by the polaroplast membrane. The polar filament runs spirally towards the posterior pole of the spore.
