Think like a bacterium

چکیده
Introduction We must, albeit reluctantly, dismiss the naive but comforting myth of the bacterial cell as a simple loner: a self-contained bag of uncompartmentalized enzymes, so exquisitely uncomplicated as to be understood outright and considered passé in this new millennium—a biological beaker for examining the more complicated eukaryotic versions of life. The recent EURESCO Conference on Bacterial Neural Networks heralded broadly the inescapable truth that bacteria cooperate in both uniform and mixed societies, sabotage the relatively mammoth creatures that they colonize, modify their own living spaces, and anticipate predictable changes in their surroundings. They achieve these feats with a clear sense of time and place, both within and outside their small but wellorganized bodies, and send and receive messages across comparatively vast space. Major themes of the meeting were the interconnected phenomena of signalling, behaviour and development, with just enough emphasis on technological advancements to presage how much more bacterial complexity is yet to be discovered as the tools improve. Overall, the conference was characterized by rigorous science that was professionally delivered by an overwhelmingly European cast of speakers and other participants (plus a few privileged interlopers such as myself). A small sampling of the diverse topics that were covered during a stimulating four-day meeting is featured here, emphasizing those presentations that best highlight aspects of the neural network theme.

Detection of a Brucella-like (Alphaproteobacteria) Bacterium in Boophilus spp. (Acari: Ixodidae) from Iran
Ticks harbor many pathogenic, as well as endosymbiotic and non-pathogenic agents. They are host of a variety of as yet unidentified microbes that continue to be described. In the present study, a Brucella-like bacterium was detected in a Boophilus tick by PCR amplification of a partial fragment of 16S rRNA locus followed sequencing. Our results show that the members of the genus Boophilus may a...

Viruses are dominant entities in the biosphere and parasitize all cellular life forms. The relative abundances of different classes of viruses are dramatically different between prokaryotes and eukaryotes. In marine, soil and animal-associated environments, virus particles consistently outnumber cells by one to two orders of magnitude. It is estimated that 10 quintillion (1030) viral particles ...

متن کاملSpeech-like Pragmatic Markers in Argumentative Essays Written by Iranian EFL Students and Native English Speaking Students
In this study, the use of speech-like pragmatic markers in Iranian EFL students’ academic writing was investigated. Speech-like pragmatic markers, such as I think, well, I guess, actually, anyway, anyhow, etc. are linguistic components that are more specific to conversation than writing, and writers may wrongly include them in their academic writing. To examine the students’ use of speech-like ...
