Honey bee samples collected between 1995 and 2007 from 12 states were examined for the presence of Nosema infections. Our results showed that Nosema ceranae is a wide-spread infection of the European honey bee, Apis mellifera in the United States. The discovery of N. ceranae in bees collected a decade ago indicates that N. ceranae was transferred from its original host, Apis cerana to A. mellif...

‎Nosemosis is one of the most prevalent bee diseases in the world causing significant ‎economic losses in the global bee-keeping industry. This cross-sectional study was conducted during April-September, 2016 to investigate the prevalence of nosemosis in different climatic regions of Iran. A total of 183 ‎apiaries were selected based on cluster sampling and the climate of apiar...

Lamerin microspridia (Lbms) isolated from Lamerin breed of the silkworm, Bombyx mori, L. and the standard strain Nosema bombycis, were induced to germinate artificially by two-step procedure. Fresh percoll purified spores were activated by incubating them in potassium hydroxide solution (KOH) (pH 11.00) and germinated artificially by using phosphate buffer saline (PBS), (pH 7.00). Germinated sp...

Nosemosis is one of the most dangerous infectious diseases honeybees in Azerbaijan and World. Nosema ceranae dominant species detected Azerbaijan, this study aimed to detect prevalence infection country. For purpose, an average 100 honeybee samples were collected from 64 hives, 24 three regions north 40 five areas south. In lab, abdomens 50 bees each group dissected crushed a container, adding ...

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...

Simultaneous and sequential per os inoculations of gypsy moth larvae with the Lymantria dispar nuclear polyhedrosis virus (LdNPV) and a Nosema sp. from Portugal demonstrated that the interaction of two pathogens during coinfection was variable, ranging from synergistic to antagonistic. Susceptibility of gypsy moth larvae to viral infection was unaffected by simultaneous and subsequent microspor...

The honeybee pathogens Nosema ceranae and deformed wing virus (DWV) cause the collapse of honeybee colonies. Therefore, it is plausible that these two pathogens act synergistically to increase colony losses, since N.ceranae causes damage to the mid-gut epithelial ventricular cells and actively suppresses the honeybees' immune response, either of which could increase the virulence of viral patho...

Nosemosis caused by the microsporidia Nosema apis and Nosema ceranae are among the most common pathologies affecting adult honey bees. N. apis infection has been associated with a reduced lifespan of infected bees and increased winter mortality, and its negative impact on colony strength and productivity has been described in several studies. By contrast, when the effects of nosemosis type C, c...
