| nosema neumanni n. sp. (microsporidia, nosematidae), a new microsporidian parasite of honeybees, apis mellifera in uganda. | the microsporidium nosema neumanni n. sp., a new parasite of the honeybee apis mellifera is described based on its ultra-structural and molecular characteristics. structures resembling microsporidian spores were found by microscopic examination of honeybees from uganda. molecular confirmation failed when pcr primers specific for nosema apis and nosema ceranae were used, but was successful with primers covering the whole family of nosematidae. we performed transmission electron microscopy and fou ... | 2017 | 28826077 |
| seasonal prevalence of pathogens and parasites in the savannah honeybee (apis mellifera scutellata). | 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 parasites) have been held responsible. work in the americas on honeybees originating mainly from south africa indicates that africanised honeybees are less affected by the interplay of pathogens and parasites. however, little is known about the health status of south ... | 2013 | 23702244 |
| nosema ceranae has been present in brazil for more than three decades infecting africanized honey bees. | until the mid-1990s, the only microsporidium known to infect bees of the genus apis was nosema apis. a second species, nosema ceranae, was first identified in 1996 from asian honey bees; it is postulated that this parasite was transmitted from the asian honey bee, apis cerana, to the european honey bee, apis mellifera. currently, n. ceranae is found on all continents and has often been associated with honey bee colony collapse and other reports of high bee losses. samples of africanized drones c ... | 2013 | 24025844 |
