materials and methods stool specimens from a random population sample were examined with light microscope, using direct fecal smear, formalin-ether concentration, and nutrient agar plate culture. results the prevalence of s. stercoralis in this study was 0.07%. the statistical random sample in this study was 2839 people whose stool specimens were collected and examined using nutrient agar plate...

high performance liquid chromatography (hplc) with diode array detection (dad) and electrospray ionization tandem mass spectrometry (esi/ms/ms) was used to analyze the main components in the methanol extract of fructus aurantii (fa) and the metabolites in rat biological samples after oral administration of the methanol extract of fa. there were 31 constituents identified in the extract of fa in...

background and objectives: tannins are toxic polyphenols that either bind and precipitate or condense proteins. the high tannin content of some plants is the preliminary limitation of using them as a ruminant feed. so, the aim of this study was the isolation and characterization of tannic acid degrading bacterial strains from goat feces before and after feeding on pis- tachio-soft hulls as tann...

to clarify fermentative alterations in the large intestine (hindgut) during grazing, fecal alcohol and volatile fatty acids (vfas) concentrations were evaluated in 30 dairy heifers. the heifers were kept in pasture growing mixed grass herbage from spring (mid may) until october, and their rectal feces were collected periodically. concentrations of ethanol, methanol and isopropanol were increase...

Nucleotide sequences of cytochrome b/tRNA/D-loop region on mitochondrial DNA of mustelids feces were compared to identify species. PCR amplification of target sequence for 47 (24.9%) feces and species identification of five feces (2.6%) out of 189 feces, collected at several study sites in Hokkaido, were successful. Species of three feces were Martes zibellina and those of other two feces were ...

background: the study was targeted to report the appearance of coproantigens in feces and circulating antibodies in the serum of fasciola gigantica  experimentally infected rabbits. methods: copro hyper immune serum (his) and excretory-secretory hyper immune serum (es his) antigens were used in a sandwich elisa for the detection of f. gigantica antigens in feces of 12 rabbits experimentally inf...

The attraction response of Stomoxys calcitrans (L.) to its own feces was evaluated in a triple cage olfactometer. Both time- and concentration-response relationships were obtained for female S. calcitrans exposed to cellulose sponges impregnated with fresh fly feces or filter papers treated with chloroform:methanol extracts of fresh fly feces in 6-min tests. Attraction to feces collected on cel...
