Acrobeloides bodenheimeri
photomicrographs by Howard Ferris and Sam Woo, UC Davis |
Lip region with projecting, rounded probolae. Stoma wall often appears distinctly separated into thickened component regions called rhabdions. Cheilostom wide, by a funnel-shaped or narrow posterior part.

Like other bacterivore nematodes, A. bodenheimeri spreads bacteria to new resources. At low nematode population levels, the beneficial effect of this "bacterial farming" on the bacterial population may exceed the negative effect of consumption of bacteria by the nematodes. "Bacterial farming" is the product of surface contamination of nematodes by bacteria and up to 40% survival of passage through the digestive tract by bacteria. One might argue that the phenomenon is mutually beneficial to both the bacteria (increased access to resources) and the nematodes (increased availability of food). If it were not mutually beneficial, there might be selection for more efficient digestion of bacteria by the nematodes.

Petri dishes were seeded with a bacterial colony in the center and with 0, 5 or 10 individuals of Acrobeloides bodenheimeri. Bacterial colony development was photographed after 48 hours. Photograph by Shenglei Fu. |
