The first report of the prevalence of Nosema ceranae in Bulgaria [PDF]
PeerJ, 2018 Nosema apis and Nosema ceranae are the two main microsporidian parasites causing nosematosis in the honey bee Apis mellifera. The aim of the present study is to investigate the presence of Nosema apis and Nosema ceranae in the area of Bulgaria.

So near and yet so far: Harmonic radar reveals reduced homing ability of nosema infected honeybees [PDF]
, 2014 Pathogens may gain a fitness advantage through manipulation of the behaviour of their hosts. Likewise, host behavioural changes can be a defence mechanism, counteracting the impact of pathogens on host fitness.

Nosemosis in Honeybees: A Review Guide on Biology and Diagnostic Methods
Applied Sciences, 2022 Nosema apis and Nosema ceranae are dangerous parasites of the honey bee (Apis mellifera). N. ceranae is more pathogenic and, nowadays, more widespread than N. apis. There are also cases of mixed infections or infections of only N. apis. Both N.

Molecular and phylogenetic characterization of honey bee viruses, Nosema microsporidia, protozoan parasites, and parasitic mites in China [PDF]
, 2008 China has the largest number of managed honey bee colonies, which produce the highest quantity of honey and royal jelly in the world; however, the presence of honey bee pathogens and parasites has never been rigorously identified in Chinese apiaries.

Stress indicator gene expression profiles, colony dynamics and tissue development of honey bees exposed to sub-lethal doses of imidacloprid in laboratory and field experiments [PDF]
, 2017 In this study, different context-dependent effects of imidacloprid exposure on the honey bee response were studied. Honey bees were exposed to different concentrations of imidacloprid during a time period of 40 days. Next to these variables, a laboratory-

Infection and transmission of Nosema bombi in Bombus terrestris colonies and its effect on hibernation, mating and colony founding [PDF]
, 2008 The impact of the microsporidium Nosema bombi on Bombus terrestris was studied by recording mating, hibernation success, protein titre in haemolymph, weight change during hibernation, and colony founding of queens that were inoculated with N.
