First Isolation of a Giant Virus from Wild Hirudo medicinalis Leech: Mimiviridae isolation in Hirudo medicinalis
Giant viruses and amoebae are common in freshwater, where they can coexist with other living multicellular organisms. We screened leeches from the species Hirudo medicinalis for giant viruses. We analyzed five H. medicinalis obtained from Tunisia (3) and France (2). The leeches were decontaminated and then dissected to remove internal parts for co-culture with Acanthamoeba polyphaga. The genome...
متن کاملSpontaneous Electrical Activity and Behavior in the Leech Hirudo Medicinalis
In the absence of external stimuli, animals explore the environment by performing irregular movements, but the neuronal mechanisms underlying this arrhythmic motion are largely unknown. In this paper, we studied the relationship between the spontaneous neuronal activity in the leech (Hirudo medicinalis) and its behavior. We analyzed the electrical activity of isolated ganglia, chains of two con...
متن کاملCholinergic action on the heart of the leech, Hirudo medicinalis.
Experiments were performed to determine the role of acetylcholine (ACh) in neuromuscular transmission in the heart of the leech Hirudo medicinalis. Superfused or iontophoretically applied ACh rapidly depolarized both isolated heart muscle cells and muscle cells in isolated hearts in a dose-dependent manner. the depolarization was associated with a conductance increase of the muscle membrane tha...
متن کاملA Study of Fibrogenesis in the Leech, Hirudo medicinalis
The fibrocytes and the fibres of Hirudo medicinalis have been studied with the electron microscope. The fibrocyte can be shown by other methods to contain triglyceride droplets, phospholipid droplets, and mitochondria, all of which can be recognized in the electron micrographs. In addition, a 'vesicular' component has been observed just below the cell surface. The collagenous 'cortex' of the fi...
متن کاملAssociative learning modifies two behaviors in the leech, Hirudo medicinalis.
We report that 2 behaviors, stepping and shortening, are modified by associative learning in the leech, Hirudo medicinalis. Experiment 1 explored conditioning of the "stepping" response. Paired presentations of touch to the medial dorsal surface of the leech and shock to the tail of the leech resulted in the development of stepping to the touch. Leeches in control groups experiencing the CS alo...
