Figure 1:

Root-knot nematodes (Meloidogyne naasi Franklin, 1965) extracted from soil and root samples collected from a football field in Portugal. A: turfgrass root showing galling by root-knot nematodes and excised M. naasi female (arrow); B: perineal pattern; C-G: second-stage juveniles: C: worm-star aggregation; D: whole body; E: pharyngeal region; F: tail; G: Pasteuria penetrans (ex Thorne, 1940) Sayre and Starr, 1985 endospores (arrows) attached to cuticle. Bars = 2000 µm (A); 125 µm (C); 25 µm (B, D-G).
