“…In this series of investigations, we observed five strains of L-forms which we induced and had the impression that there were many strains with different modes of reproduction as well as various kinds of structures in the staphylococcal L-forms. In our experiments, many forms of binary-like fission or filamentous forms which have been described by many investigators (9,12) were also observed in the other L-form strains. We will describe these elsewhere in detail.…”

“…Dienes et al (5,6,7,8) proposed that small bodies were the minimal reproducible unit using a membrane filtration technique. On the other hand, other investigators (9,12) suggested that these small bodies were not able to reproduce and L-forms reproduce by binary fission.…”

“…Mollicutes are polymorphic microorganisms (spheroid, filamentous, ramified, helicoïdal) characterized by an absence of a cell wall, and therefore poorly resistant to extreme environments. Usually, Mollicutes have a reduced genome and depend on host nutrients (Maniloff & Morowitz, 1972;Razin, 1978Razin, , 1998Clark, 1984;Regassa & Gasparich, 2006). The midgut of R. exoculata does not moult and is relatively independent of environmental conditions, suggesting that it could be a sufficiently stable habitat to harbour Mollicutes.…”

Rimicaris exoculata dominates the megafauna of several Mid-Atlantic Ridge hydrothermal sites. Its gut is full of sulphides and iron-oxide particles and harbours microbial communities. Although a trophic symbiosis has been suggested, their role remains unclear. In vivo starvation experiments in pressurized vessels were performed on shrimps from Rainbow and Trans-Atlantic Geotraverse sites in order to expel the transient gut contents. Microbial communities associated with the gut of starved and reference shrimps were compared using 16S rRNA gene libraries and microscopic observations (light, transmission and scanning electron microscopy and FISH analyses). We show that the gut microbiota of shrimps from both sites included mainly Deferribacteres, Mollicutes, Epsilon- and Gammaproteobacteria. For the first time, we have observed filamentous bacteria, inserted between microvilli of gut epithelial cells. They remained after starvation periods in empty guts, suggesting the occurrence of a resident microbial community. The bacterial community composition was the same regardless of the site, except for Gammaproteobacteria retrieved only in Rainbow specimens. We observed a shift in the composition of the microbiota of long-starved specimens, from the dominance of Deferribacteres to the dominance of Gammaproteobacteria. These results reinforce the hypothesis of a symbiotic relationship between R. exoculata and its gut epibionts.

“…It merits particular attention, since similar viruses have been reported in Acholeplasma laidlawii. 26 In cases where the virus-like particles cannot be proved to cause a plant disease but are closely associated with MLOs in plant tissue, it may be that the particles are a "phagelike" virus of the MLO. The possibility that some of the virus-like particles observed to be associated with the MLO are simply latent plant viruses cannot be dismissed, either.…”
