To better understand the potential environmental health risk presented by West Nile virus (WNV)-contaminated feces, we quantified the amount of WNV present in the feces of experimentally infected American crows (Corvus brachyrhynchos) and fish crows (Corvus ossifragus). Peak fecal titers ranged from 10(3.5) to 10(8.8) plaque-forming units (PFU)/g for 10 American crows and from 10(2.3) to 10(6.4...

No urobilinogens are present in the feces or urine of germfree rats. After contamination of germfree animals with feces from conventional animals the exgermfree rats produced urobilins to the same extent as conventional animals on the same diet. The negative urobilin test turned positive in germfree animals infected with a single Clostridium-like microorganism isolated from the intestinal conte...

Two 16S rRNA-targeted probes were developed: one for the Coriobacterium group and the other for the Atopobium cluster (which comprises most of the Coriobacteriaceae species, including the Coriobacterium group). The new probes were based on sequences of three new Coriobacteriaceae strains isolated from human feces and clinical material and sequences from databases. Application of the probes to f...

Bartonella henselae (Rhizobiales: Bartonellaceae) is a Gram-negative fastidious bacterium of veterinary and zoonotic importance. The cat flea Ctenocephalides felis (Siphonaptera: Pulicidae) is the main recognized vector of B. henselae, and transmission among cats and humans occurs mainly through infected flea feces. The present study documents the use of a quantitative molecular approach to fol...

The feed and feces of a continuously fed sheep were analyzed for carbon, hydrogen, and nitrogen, with oxygen as the remainder. The daily feed-feces weight difference was used as the reactant in an equation representing the rumen fermentation. The measured products were the daily production of volatile fatty acids (VFA), CH4, CO2, and ammonia. The carbon unaccounted for was assumed to be in the ...

Digestion of green plants in the gastrointestinal (GI) tract produces degradation products from chlorophyll that cause ingesta and feces to be highly fluorescent. This property was exploited for development and construction of instruments to noninvasively detect minute quantities of feces on meat samples in real time. The presence of feces on meat products is a primary source of foodborne patho...

Ostriches are frequently infected with viral, fungal, and bacterial diseases. This disease does not require airborne transmission involve the respiratory system. Objective: To determine antimicrobial activity of Moringa oleifera tea leaves seed against bacteria in Ostrich feces. Methods: Fecal samples were collected from captive ostriches at W.A Apparel factory. E. coli was isolated after inocu...
