Reptiles were found the be the host of the parasites of the genera Schellackia and Lankesterella, as these parasites undergo their entire life cycle in the reptilian body, with an intermediate stage of dormancy ...
متن کاملInitial Cellular Interactions Between Thielaviopsis basicola and Tobacco Root Hairs.
ABSTRACT Cellular events that occur during the initial interactions between Thielaviopsis basicola and root hairs of tobacco (Nicotiana tabacum) were examined microscopically. Time-course documentation of the infection process indicated a dynamic interaction between T. basicola and the living host cell. Upon root hair contact and recognition, the vegetative apex of T. basicola rapidly different...
متن کاملSpecific composition and morphological peculiarities of endemic monogenean parasites of freshwater fishes of Iran
Result obtained during ten years research work (1990-2000) on distribution of monogenean fauna Iranian fishes indicates that its composition of monogenean fauna of Iranian fishes depends on their habit and since Iran includes three different zoogeographical zones with highly endemic fish hosts, its monogenean parasites have specific composition. The Caspian fauna is characterized by relatively ...
متن کاملPersian Phone Recognition Using Acoustic Landmarks and Neural Network-based variability compensation methods
Speech recognition is a subfield of artificial intelligence that develops technologies to convert speech utterance into transcription. So far, various methods such as hidden Markov models and artificial neural networks have been used to develop speech recognition systems. In most of these systems, the speech signal frames are processed uniformly, while the information is not evenly distributed ...
متن کاملThe Effects of Psychological Stress and Other Environmental Factors on Incidence of Diseases
The main purpose of this paper has been to discuss the effects of psychological stress and other environmental factors on incidence of diseases. We were specifically concerned with stress that increased susceptibility of uninfected hosts when exposed to infection. If such stresses also reduced resources, fecundity and/or survivorship, there was a reduction in the host carrying capacity. In addi...
