Antimicrobial resistance among Clostnridium perfringens isolated from feces of humans and pigs, food and other environmental sources was examined by testing of 201 PCR-confirmed strains for resistance to 7 antimicrobial agents. The minimal inhibitory concentrations (MICs) were determined by the agar dilution method. Overall, C. perfringens showed the highest resistance to tetracycline (56.2%), ...

Waterbird feces (mainly mallard Anas platyrhynchos and coot Fulica atra) were collected from four wetlands in Southern Spain in the field or during capture (n = 558 and n = 59, respectively) to study lead (Pb) shot ingestion. Lead and aluminum (Al) concentrations along with Pb isotope signatures were used to identify sources of Pb exposure. The profile and concentrations of porphyrins and biliv...

The purpose of this study was to investigate the presence of the anaerobic intestinal spirochetes Brachyspira aalborgi and Brachyspira pilosicoli in the feces of captive nonhuman primates (n = 35) from 19 species housed at the Zoological Gardens, Perth, Western Australia. Both spirochete species are known to infect human beings. DNA was extracted from freshly collected feces with a commercially...

The effect of 2 different blends of essential oils on Clostridium perfringens (Cp) in the intestine and feces of broiler chickens was tested in 6 field trials for each blend. One hundred parts per million of the blends were mixed in a commercial corn-based diet throughout the entire growing period for experimental flocks. Samples from the jejunum, cecum, cloaca, and feces were taken on d 14, 21...

The present study shows that feces samples of 14 human volunteers and isolated gut segments of mice (small intestine, cecum, and large intestine) are able to transform metals and metalloids into volatile derivatives ex situ during anaerobic incubation at 37 degrees C and neutral pH. Human feces and the gut of mice exhibit highly productive mechanisms for the formation of the toxic volatile deri...

This study monitored fecal cortisol and corticosterone levels in 14 black rhinoceroses (Diceros bicornis) and in seven white rhinoceroses (Certotherium simum) under various conditions of captivity, including translocation. Free cortisol and free corticosterone were measured in methylene chloride extracts of feces, using high-performance liquid chromatography (HPLC). The extraction-assay method ...

The pattern of metabolites produced by the gut microbiome comprises a phenotype indicative of the means by which that microbiome affects the gut. We characterized that phenotype in mice by conducting metabolomic analyses of the colonic-cecal contents, comparing that to the metabolite patterns of feces in order to determine the suitability of fecal specimens as proxies for assessing the metaboli...

Biogas is a type of gaseous fuel obtained through the anaerobic fermentation process organic matter into methane gas, one ingredients for making biogas cow dung vegetable waste. The purpose this study was to determine variation mixture col waste with feces on efficiency and calorific value biogas. research method used an experimental scale 20 liters digester volume. results five variations mixe...

Almost 50 years ago, Munk and Rosenstein (1) reported the feeding of cetyl palmitate, as spermaceti, to a patient suffering from a chronic chyle fistula. Whereas they could recover a good portion of the palmitic acid, as tripahnitin, from the chyle, they were unable to demonstrate the presence of any cetyl alcohol in this material. It has since been shown by Mancke (2) that, even when large amo...

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 infe...
