Scanning Behavior in the Medicinal Leech Hirudo verbana
While moving through their environment, medicinal leeches stop periodically and wave their head or body back and forth. This activity has been previously described as two separate behaviors: one called 'head movement' and another called 'body waving'. Here, we report that these behaviors exist on a continuum, and provide a detailed description of what we now call 'scanning'. Scanning-related be...
متن کاملSerotonin modulates muscle function in the medicinal leech Hirudo verbana.
The body wall muscles of sanguivorous leeches power mechanically diverse behaviours: suction feeding, crawling and swimming. These require longitudinal muscle to exert force over an extremely large length range, from 145 to 46 per cent of the mean segmental swimming length. Previous data, however, suggest that leech body wall muscle has limited capacity for force production when elongated. Sero...
متن کاملIdentification of Aeromonas veronii genes required for colonization of the medicinal leech, Hirudo verbana.
Most digestive tracts contain a complex consortium of beneficial microorganisms, making it challenging to tease apart the molecular interactions between symbiont and host. The digestive tract of Hirudo verbana, the medicinal leech, is an ideal model system because it harbors a simple microbial community in the crop, comprising the genetically amenable Aeromonas veronii and a Rikenella-like bact...
متن کاملNiabella hirudinis and Niabella drilacis sp. nov., isolated from the medicinal leech Hirudo verbana.
Two Gram-negative, rod-shaped bacteria, strains E96(T) and E90(T), were isolated from medicinal leeches (Hirudo verbana) and characterized by a polyphasic taxonomic approach. Phylogenetic analysis based on the nearly full-length 16S rRNA gene sequence showed that the two strains shared 98.1% sequence similarity and were affiliated with the genus Niabella within the phylum Bacteroidetes, with 94...
متن کاملBuilding exploration with leeches Hirudo verbana
Safe evacuation of people from building and outdoor environments, and search and rescue operations, always will remain actual in course of all socio-technological developments. Modern facilities offer a range of automated systems to guide residents towards emergency exists. The systems are assumed to be infallible. But what if they fail? How occupants not familiar with a building layout will be...
