Interactions between pesticides and parasites are believed to be responsible for increased mortality of honey bee (Apis mellifera) colonies in the northern hemisphere. Previous efforts have employed experimental approaches using small... more
Host-parasite interactions are often characterized by changes in the host behaviour, which are beneficial to either the parasite or the host, or are a non-adaptive byproduct of parasitism. These interactions are further complicated in... more
La octava edición de Ciencias de la tierra: una introducción a la geología física, como sus predecesoras, es un texto universitario para estudiantes que cursan su primer año de Geología. Además de ser informativo y estar actualizado, uno... more
The loss of Apis mellifera L. colonies in recent years has, in many regions of the world, been alarmingly high. No single cause has been identified for these losses, but the interactions between several factors (mostly pathogens and... more
DNA metabarcoding offers new perspectives, especially with regard to the high‐throughput identification and diagnostics of pathogens. Microsporidia are an example of widely distributed, opportunistic and pathogenic microorganisms in which... more
Nosema ceranae and Nosema apis are two fungal pathogens belonging to the phylum Microsporidia and infecting the European honeybee, Apis mellifera. Recent studies have suggested that N. ceranae is more virulent than N. apis both at the... more
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... more
Spores of the microsporidian gut pathogens of honey bees Nosema apis and Nosema ceranae, the causative agents of nosemosis, are difficult to distinguish using the light microscope. This study aimed to find methods which could help to... more
Nosema ceranae is a new and emerging microsporidian parasite of European honey bees, Apis mellifera that has been implicated in colony losses worldwide. RNA interference (RNAi), a post-transcriptional gene silencing mechanism, has emerged... more
Nosema ceranae, a microsporidian parasite originally described in the Asian honey bee Apis cerana, has recently been found to be cross-infective and to also parasitize the European honey bee Apis mellifera. Since this discovery, many... more
Nosema apis and Nosema ceranae are intracellular microsporidian parasites infecting the midgut epithelial cells of adult honey bees. N. ceranae was considered to be restricted to the Asian honey bee, Apis cerana, but is nowadays a... more
