Parasitological and molecular study of nosemosis in migratory apiaries in Hormozgan Province, southern Iran [PDF]

نامه انجمن حشره‌شناسی ایران, 2023
Nosemosis is a microsporidian disease caused by Nosema ceranae and N. apis and transmitted via oral-fecal and oral-oral routes. It is globally distributed among adult bees in honeybee colonies. Considering the health importance of nosemosis in honeybees,

Nosema apis and Nosema ceranae Tissue Tropism in Worker Honey Bees (Apis mellifera) [PDF]

Veterinary Pathology, 2019
The microsporidia Nosema apis and Nosema ceranae are major honey bee pathogens that possess different characteristics in terms of the signs they produce, as well as disease development and transmission. Although the ventricular epithelium is generally considered the target tissue, indirect observations led to speculation that N.

First Identification of Nosema Ceranae (Microsporidia) Infecting Apis Mellifera in Venezuela

Journal of Apicultural Science, 2017
Nosema ceranae is a pathogen of Apis mellifera, which seems to have jumped from its original host Asiatic honey bee Apis ceranae. Nosemosis which affects the honey bee Apis mellifera is caused by two parasitic fungi described as etiologic agents of the ...

Association between the Microsatellite Ap243, AC117 and SV185 Polymorphisms and Nosema Disease in the Dark Forest Bee Apis mellifera mellifera

Veterinary Sciences, 2020
The microsporidian Nosema parasites, primarily Nosema ceranae, remain critical threats to the health of the honey bee Apis mellifera. One promising intervention approach is the breeding of Nosema-resistant honey bee colonies using molecular technologies,

The cost of promiscuity: sexual transmission of Nosema microsporidian parasites in polyandrous honey bees [PDF]

, 2015
Multiple mating (and insemination) by females with different males, polyandry, is widespread across animals, due to material and/or genetic benefits for females.
