The results suggest that N. ceranae is widely distributed in Argentina and that the genetic variation observed between the different isolates could be related with the difference in the symptomatology found previously by this work group.
Nosema ceranae development in Apis mellifera: influence of diet and infective inoculum

The results indicate that this parasite multiplies successfully regardless of the inoculum given or the nutritional status of its host, demonstrating a parasite development that depends on host-condition.

Examination of individual midgut homogenates on day 19 post-infection indicated that 1% concentration of L. nobilis extract significantly inhibited N. ceranae development, and ten percent concentrations showed high toxicity on infected bees, but also a significant activity diminishing parasitosis development in short periods.

One of the surfactins is herein postulated as a molecule capable of reducing N. ceranae development, acting either by direct exposure to purified spores or incorporated into the digestive tract of the bee.

Laurel leaf extracts for honeybee pest and disease management: antimicrobial, microsporicidal, and acaricidal activity

The absence of topical and oral toxicity of the ethanol extract on bees and the strong antimicrobial, microsporicidal, and miticidal effects registered in this study place this laurel extract as a promising integrated treatment of bee diseases and stimulates the search for other bioactive phytochemicals from plants.
Sublethal effects of acaricides and Nosema ceranae infection on immune related gene expression in honeybees

Honeybee survival was not affected by any of the treatments, and parasite development was not altered by acaricide treatments, while coumaphos exposure decreased lysozyme expression and N. ceranae reduced levels of vitellogenin transcripts independently of the presence of acaricides.
Synergistic effect of surfactin from Bacillus subtilis C4 and Achyrocline satureioides extracts on the viability of Paenibacillus larvae

The in vitro effect of the mixture between the lipopeptide surfactin and the most active vegetal extract from Achyrocline satureioides on local strains of Paenibacillus larvae, the agent of American Foulbrood in honeybees, revealed a synergistic action on P. larvae.
Parasitic interactions between nosema spp. and varroa destructor in apis mellifera colonies

The European honey bee Apis mellifera is affected by many parasites and pathogens that modify its immune system being the most destructive ectoparasitc mite Varroa destructor, and abundance of Nosema abundance is explained by the time and by the interaction between the month and the V. destructor infestation.
Lactobacillus kunkeei strains decreased the infection by honey bee pathogens Paenibacillus larvae and Nosema ceranae.

A mixture of four Lactobacillus kunkeei strains isolated from the gut microbial community of bees, and evaluated its potential beneficial effect on larvae and adult bees suggested that this beneficial microorganism's mixture may be an attractive strategy to improve bee health.
