“…But myxobacteria on dung collected on thick layers of snow suggest that they may pass through the digestive track of the animal (Rückert, 1975a; personal observation). This has indeed been shown by pipette feeding fruiting bodies of Chondromyces to white mice in the laboratory and demonstrating the organism, certainly absent in that environment, on the faeces of the animals (Kühlwein, 1950). Myxobacteria have also been isolated regularly from the gut content of carp, and it has been concluded that they pass through rather than inhabit the fish (Till, 1982).…”

What are myxobacteria?Myxobacteria are Gram-negative eubacteria with relatively large (0.6-1.2 by 3-15 m) rod-shaped cells. They live in soil and related habitats and are famous for three capabilities: (i) they move by gliding and their colonies are therefore thin, film-like swarms that spread gradually over the culture plate; (ii) they have sophisticated intercellular communication systems and a highly developed social life; and (iii) they show a remarkable morphogenetic potential, which is expressed on two levels. In a co-operative morphogenesis involving 10 5 -10 6 cells, induced by starvation conditions, they may produce a fruiting body. Within the maturing fruiting body, a cellular morphogenesis takes place, during which the vegetative cells convert into desiccation-resistant myxospores. It might also be mentioned that myxobacteria have the largest genomes of all bacteria (9500-10 000 kbp) and a DNA with a G þ C content of 66-72 mol%. Details can be found in several reviews (Reichenbach and

“…This was spectacular, because until such time, C. crocatus had been considered a slime mold for more than 20 years [ 14 ]. Studies by Bauer [ 21 ], Kofler [ 20 ], Jahn [ 22 , 23 ], and Kühlwein [ 24 ] followed in the early 20th century. Myxobacteria have always fascinated scientists due to their social behavior, including cooperative swarming, group predation, and multicellular fruiting body formation.…”

The discovery of new antibiotics is mandatory with regard to the increasing number of resistant pathogens. One approach is the search for new antibiotic producers in nature. Among actinomycetes, Bacillus species, and fungi, myxobacteria have been a rich source for bioactive secondary metabolites for decades. To date, about 600 substances could be described, many of them with antibacterial, antifungal, or cytostatic activity. But, recent cultivation-independent studies on marine, terrestrial, or uncommon habitats unequivocally demonstrate that the number of uncultured myxobacteria is much higher than would be expected from the number of cultivated strains. Although several highly promising myxobacterial taxa have been identified recently, this so-called Great Plate Count Anomaly must be overcome to get broader access to new secondary metabolite producers. In the last years it turned out that especially new species, genera, and families of myxobacteria are promising sources for new bioactive metabolites. Therefore, the cultivation of the hitherto uncultivable ones is our biggest challenge.
