Nosemosis bal arılarında (Epis mellifera) sıkça görülen küresel bir hastalıktır. Hastalığın etkeni fungal mikroorganizmalar olan Nosema apis ve ceranae’dir. Bu çalışmada Siirt Şanlıurfa’da verimi düşük zayıf (popülasyonu düşük) arı kolonilerinde spp. sporlarının varlığının mikroskobik olarak muayene edilmesi pozitif bulunan örneklerden, multipleks PCR (Polimeraz zincir reaksiyonu) ile etkenin t...

nosema apis is an obligate intracellular parasite belonging to phylum microsporidia. this para site is known as main causative agent of nosemosis in honeybees especially in the european honeybee (apis mellifera). nosemosis can cause queen supersedure, reduction of honey yield and dwindling the population of honeybees. a total number of 54 apiaries were randomly sampled from april to july 2011 a...

In this study, two halophilic bacterial strains isolated from saline habitats in Argentina grew in the presence of gas oil. They were identified as Halomonas spp. and Nesterenkonia sp. by 16S ribosomal RNA sequencing. Chemotaxis towards gas oil was observed in Halomonas spp. by using swimming assays.

Objectives: Royal jelly (RJ), a secretion of both the hypopharyngeal and mandibular glands of nurse workers, is believed to play a central role in honeybee queen development. Important component of royal jelly are proteins which form about 50% of the dry mass of RJ. Major royal jelly proteins (MRJPs) are the dominant proteinaceous component of royal jelly and constitute about 82-90% of total pr...

Mexico is a major honey producer, but not much information exists about the health status of bees (Apis mellifera L.) in country. This study was conducted to determine sanitary adult Mexico’s five beekeeping regions. Samples from 369 apiaries were diagnosed identify pathogens such as Varroa destructor, which quantified, Acarapis woodi, Nosema spp., and viruses. Colonies also inspected for prese...

Parasites and pathogens are apparent key factors for the detrimental health of managed European honey bee subspecies, Apis mellifera. Apicultural trade is arguably the main factor for the almost global distribution of most honey bee diseases, thereby increasing chances for multiple infestations/infections of regions, apiaries, colonies and even individual bees. This imposes difficulties to eval...
