Biological values of the infant, juvenile, and adult agouti (Dasyprocta sp) with emphasis on microbial flora.

Normal values for intestinal flora were determined on four adult, two juvenile, and four infant agoutis (Dasyprocta sp) maintained at our institution. Serologic, hematologic, biochemical, and histologic observations were also made on these same agoutis, and serologic, microbiologic, and endoparasitic tests were made on serum and fecal samples from agoutis maintained at other institutions. Streptococci, lactobacilli and nonenteropathogenic Escherichia coli were isolated from cecal contents of all age groups. Gaffkya tetragena and Bacillus sp were recovered from infant agoutis, Proteus mirabilis from juvenile agoutis, and Proteus mirabilis and Micrococcus sp from adult agoutis. Infant agoutis showed marginal antibody titers to reovirus type 3 and Toolan's H-1 viruses, and Theiler's GDVII antibodies were detected in juvenile agoutis, but no antibody titers to murine viruses were found in the adult agoutis maintained at our institution. Hematologic, biochemical, and histologic data for these agoutis were comparable to those of other hystricomorph rodents. Serologic tests of the agoutis maintained at other institutions disclosed antibodies for GDVII virus in all of 17 animals tested, while marginal titers were found for Sendai virus in four and for reovirus type 3 in eight of the 17 animals. Only low incidences of pathogenic bacteria (Salmonella, Pseudomonas, and Citrobacter) were isolated from the agoutis maintained elsewhere. The endoparasites found in these agoutis were Ascaris, Toxascaris, Strongyloides, Trichuris, and Trichomonas.
