Nosema notabilis (Microsporidia), its ultrastructure and effect on the myxosporean host Ortholinea polymorpha.
Nosema notabilis Kudo, 1939 produces chain-forming meronts with a dense cell coat in direct contact with the host cell cytoplasm. Cytoplasmic microtubules and membranaceous whorls could be observed in meront cytoplasm. Sporonts differ in that they have a thicker cell wall and more conspicuous endoplasmic reticulum (ER) cisternae. Sporoblasts have an externally ridged cell wall. Spores have an a...
متن کاملan investigation of the impact of self monitoring on langauge teachers motivational practice and its effect on learners motivation
the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
the effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولCophylogeny of Nosema (Microsporidia: Nosematidae) and bees (Hymenoptera: Apidae) suggests both cospeciation and a host-switch.
Some microsporidian parasites belonging to the genus Nosema infect bees. Previous phylogenies of these parasites have produced alternative, conflicting relationships. We analyzed separately, and in combination, large and small subunit ribosomal DNA sequences of Nosema species infecting bees under neighbor-joining, maximum parsimony, maximum likelihood, and Bayesian frameworks. We observed a sis...
متن کاملEasy labeling of proliferative phase and sporogonic phase of microsporidia Nosema bombycis in host cells
Microsporidia are eukaryotic, unicellular parasites that have been studied for more than 150 years. These organisms are extraordinary in their ability to invade a wide range of hosts including vertebrates and invertebrates, such as human and commercially important animals. A lack of appropriate labeling methods has limited the research of the cell cycle and protein locations in intracellular st...
