The comparison of rDNA spacer regions of Nosema ceranae isolates from different hosts and locations

Dominance of Nosema ceranae in honey bees in the Balkan countries in the absence of symptoms of colony collapse disorder

“…In addition, the recent reports of causative association between the presence of N. ceranae, bee losses ) and the sudden colony collapse of western honey bees due to N. ceranae (Higes et al, 2008(Higes et al, , 2009b . Although most honey bee colonies and individual bees may be co-infected with both microsporidian species, N. apis and N. ceranae Paxton et al, 2007), no co-infections were found in our study, similarly to the findings of Huang et al (2008) in Taiwan and Martinique. Such results question whether or not N. apis was ever prevalent in Balkan countries.…”

Screening of natural compounds for the control of nosema disease in honeybees (Apis mellifera)

“…Nosema disease in European honeybees (Apis mellifera L.) is caused by the microsporidian Nosema apis Zander, although recent studies have shown that the microsporidian Nosema ceranae (Fries et al, 1996), first isolated from the Asian honeybee (Apis cerana Fabricius), can infect A. mellifera (Higes et al, 2006;Huang et al, 2007Huang et al, , 2008 and may be responsible for the increase of the incidence of the disease observed in some European countries (Martín et al, 2005). Nosema apis is an obligate parasite of the gut tissue of Corresponding author: Lara Maistrello, lara.maistrello@unimore.it * Manuscript editor: Marla Spivak adult bees (de Graaf et al, 1994); transmission of the disease occurs via trophallaxis (Webster, 1993) and ingestion of infected comb (Bailey and Ball, 1991) and water sources (L'Arrivee, 1965), as the spores expelled in large quantities with the faeces of diseased individuals remain viable for more than a year (Fries, 1993).…”

Detection of a Microsporidium, Nosema ceranae, from Field Population of the Bumblebee, Bombus terrestris, via Quantitative Real-Time PCR

“…노제마감염은 미포자충이 성충을 감염시켜 기생하여 발생하는 내부기생충성 전염병으로, 노제마병 감염으로 인해 수명단축, 여왕벌교체, 소화장애, 벌꿀수확량감소, 작물수확량 감소 등이 보고되었다 (Fries et al, 1984;Anderson and Giacon, 1992;Malon et al, 1995 (Fries et al, 1996)가 있었고, 두 종간의 낮은 SSU rRNA 상동성에 관한 연구 (Huang et al, 2008) (Huang et al, 2004;Tsai et al, 2005;Ku et al, 2007 …”

“…위에 언급된 3종의 Nosema는 형태적, 유전적, 병리적 특 징이 잘 연구되어 있다 (Fries et al, 2001;Chen et al, 2009 (Hamiduzzaman et al, 2010). Nosema spp.에 속 하는 종들을 구별하기 위해 PCR 후 염기서열검정 Chen et al, 2008) …”
