Individual Variability of Nosema ceranae Infections in Apis mellifera Colonies
Since 2006, beekeepers have reported increased losses of Apis mellifera colonies, and one factor that has been potentially implicated in these losses is the microsporidian Nosema ceranae. Since N. ceranae is a fairly recently discovered parasite, there is little knowledge of the variation in infection levels among individual workers within a colony. In this study we examined the levels of infec...
متن کاملFirst Detection of Nosema ceranae, a Microsporidian Protozoa of European Honeybees (Apis mellifera) In Iran
BACKGROUND Nosemosis of European honey bee (Apis mellifera) is present in bee colonies worldwide. Until recently, Nosema apis had been regarded as the causative agent of the disease, that causes heavy economic losses in apicultures. Nosema ceranae is an emerging microsporidian parasite of European honeybees, A. mellifera, but its distribution is not well known. Previously, nosemosis in honeybee...
متن کاملPhysiological and Behavioral Changes in Honey Bees (Apis mellifera) Induced by Nosema ceranae Infection
Persistent exposure to mite pests, poor nutrition, pesticides, and pathogens threaten honey bee survival. In healthy colonies, the interaction of the yolk precursor protein, vitellogenin (Vg), and endocrine factor, juvenile hormone (JH), functions as a pacemaker driving the sequence of behaviors that workers perform throughout their lives. Young bees perform nursing duties within the hive and h...
متن کاملPopulation Genetics of Nosema apis and Nosema ceranae: One Host (Apis mellifera) and Two Different Histories
Two microsporidians are known to infect honey bees: Nosema apis and Nosema ceranae. Whereas population genetics data for the latter have been released in the last few years, such information is still missing for N. apis. Here we analyze the patterns of nucleotide polymorphism at three single-copy loci (PTP2, PTP3 and RPB1) in a collection of Apis mellifera isolates from all over the world, natu...
متن کاملColony Level Prevalence and Intensity of Nosema ceranae in Honey Bees (Apis mellifera L.)
Nosema ceranae is a widely prevalent microsporidian parasite in the western honey bee. There is considerable uncertainty regarding infection dynamics of this important pathogen in honey bee colonies. Understanding the infection dynamics at the colony level may aid in development of a reliable sampling protocol for N. ceranae diagnosis, and provide insights into efficient treatment strategies. T...
