Asymmetrical coexistence of Nosema ceranae and Nosema apis in honey bees.
Globalization has provided opportunities for parasites/pathogens to cross geographic boundaries and expand to new hosts. Recent studies showed that Nosema ceranae, originally considered a microsporidian parasite of Eastern honey bees, Apis cerana, is a disease agent of nosemosis in European honey bees, Apis mellifera, along with the resident species, Nosema apis. Further studies indicated that ...
متن کاملInfectivity and virulence of Nosema ceranae and Nosema apis in commercially available North American honey bees.
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. apis in commercially available lineages of honey bees in studies conduc...
متن کاملDoes 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 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...
