Rm. Pinto et al., Worm burdens in outbred and inbred laboratory rats with morphometric data on Syphacia muris (Yamaguti, 1935) Yamaguti, 1941 (Nematoda, Oxyuroidea), MEM I OSW C, 96(1), 2001, pp. 133-136
Syphacia muris worm burdens were evaluated in the rat Rattus norvegicus of
the strains Wistar (outbred), Low/M and AM/2/Torr (inbred), maintained conv
entionally in institutional animal houses in Brazil. Morphometrics and illu
stration data for S. muris recovered from Brazilian laboratory rats are pro
vided for the first time since its proposition in 1935.
