Does Nosema ceranae Wipe Out Nosema apis in Turkey?
BACKGROUND The aim of this study was to determine the prevalence of the Nosema ceranae and Nosema apis among apiaries using both spore counts and multiplex PCR and the replacement of N. apis by N. ceranae in some regions of Turkey. METHODS A hundred honey bee samples were collected from 99 apiaries in 11 different locations in 2011-2012 in Turkey. Nosema infection degree from collected sample...
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 کاملEffects of Nosema apis, N. ceranae, and coinfections on honey bee (Apis mellifera) learning and memory
Western honey bees (Apis mellifera) face an increasing number of challenges that in recent years have led to significant economic effects on apiculture, with attendant consequences for agriculture. Nosemosis is a fungal infection of honey bees caused by either Nosema apis or N. ceranae. The putative greater virulence of N. ceranae has spurred interest in understanding how it differs from N. api...
متن کاملIndividual 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 کاملImmune suppression in the honey bee (Apis mellifera) following infection by Nosema ceranae (Microsporidia).
Two microsporidia species have been shown to infect Apis mellifera, Nosema apis and Nosema ceranae. This work presents evidence that N. ceranae infection significantly suppresses the honey bee immune response, although this effect was not observed following infection with N. apis. Immune suppression would also increase susceptibility to other bee pathogens and senescence. Despite the importance...
