Neutrophils polarize their cytoskeleton to form a leading edge (lamellipodia or pseudopod) towards the signal of origin and a trailing uropod in the posterior of the cell.
Each female was branded by the ablation and cuts on the uropods for identification.
Twenty-four hours later, these animals were clearly infected, showing fragile antennas and soft cuticle as well as chromatophore expansion along the whole surface of the body, particularly at the tail fan (telson and uropods).
It differs from other isopods in New Mexico by being aquatic and having two pairs of oar-like appendages (uropods) attached to the abdomen.
Mussels colonized virtually all areas of the crayfish bodies but the chelae, telson and uropods and thorax were most heavily colonized.
Gammarus fossarum Koch is one of the four species of gammarids of the pulex group (Karaman and Pinkster 1977a, b, 1987), recognizable by the setation of the second antennae and the morphology of uropods and pleopods (Roux 1963, Goedsmakers 1981b).
