Photomicrograph of Caenorhabditis briggsae hermaphrodite isolated from Lissachatina fulica from Bukidnon, Philippines.

Phylogenetic tree as inferred from the Bayesian inference analysis between four Caenorhabditis briggsae strains and other closely related strains are provided based on the D2-D3 fragment of 28S rDNA region. Bayesian phylogenetic analysis was carried out using the GTR + I + G nucleotide substitution model; analyses were run under 1 × 106 generations (4 runs).
