MMG will have two consecutive issue covers in the Journal, Applied and Environmental Microbiology:

The first, shown above, is from a paper from Tom Schmidt's lab:  AEM, March 2008, p. 1575-1582, Vol. 74, No. 5.

Phylogenetic Characterization and Prevalence of "Spirobacillus cienkowskii," a Red-Pigmented, Spiral-Shaped Bacterial Pathogen of Freshwater Daphnia Species

Jorge L. M. Rodrigues, Meghan A. Duffy, Alan J. Tessier, Dieter Ebert, Laurence Mouton, and Thomas M. Schmidt

Spirobacillus cienkowskii

 

 

The striking visual difference between a healthy specimen of Daphnia dentifera (top panel, left) and one infected by a red-pigmented bacterium (right) results in preferential feeding on infected individuals by planktivorous fish.  Electron microscopy reveals dense growth of the pathogen and its spiral shape (bottom panel) that was initially described over 100 years ago by Elie Metchnikoff.  Molecular phylogenetic analyses identify the bacterium as a deeply divergent member of the delta Proteobacteria.

 

  The second paper is from Todd Ciche's lab. The cover is shown below.

 

Symbiont discrimination in a nematode intestine. Shown is the insect-parasitic nematode Heteorhabditis bacteriophora containing transient Escherichia coli cells (green) and a biofilm of symbiotic Photorhabdus temperata cells (red). Only cells that form a biofilm on the posterior intestine persist to later invade the rectal gland cells before being released to nematode offspring developing inside the maternal body cavity.
