Fecal samples obtained from wild boar habitats are useful for the surveillance of diseases in wild boar populations; however, it is difficult to determine the species of origin of feces collected in natural habitats. In this study, a fecal IgA ELISA was evaluated as a method for identifying the porcine species from fecal samples. Both domestic pigs (Sus scrofa domestica) and wild boars (Sus scr...

Advances have been made to standardize 16S rRNA gene amplicon based studies for inter-study comparisons, yet there are many opportunities for systematic error that may render these comparisons improper and misleading. The fecal microbiome of horses has been examined previously, however, no universal horse fecal collection method and sample processing procedure has been established. This study w...

In contrast, enterotoxin was not demonstrable in fecal samples of apparently healthy individuals both at high...

background: microsporidia species are obligatory intracellular agents that can in­fect all major animal groups including mammals, birds, fishes and insects. whereas world­wide human infection reports are increasing, the cognition of sources of infec­tion particularly zoonotic transmission could be helpful. we aimed to detect zoono­tic microsporidia spore in fecal samples from some animals with ...

Samples from cattle, other domestic and wild animals, flies, feeds, and water-troughs were collected from 12 cattle farms and tested for Escherichia coli O157. E. coli O157 was isolated from bovine fecal samples on all 12 farms with a within herd prevalence ranging from 1.1% to 6.1%. E. coli O157 was also found in 1 of 90 (1.1%) equine fecal samples, 2 of 65 (3.1%) canine fecal samples, 1 of 20...

Group A rotaviruses (GARVs) cause acute diarrhea and malabsorption in new-born and young piglets, resulting in high mortality and morbidity. Evidence of this infection has been reported in various European countries. However, there is little evidence of porcine GARV infections in Romania. The aim of this study was the detection of the GARV in an outbreak of diarrhea in piglets and sows farmed i...

The objectives of this study were to investigate the effects of dietary crude protein (14.5 or 12.0%) and cellulose (8.7 or 2.5%) levels on composition of feces and manure after 8 wk of diet feeding and storage. Pigs were fed twice daily; after each feeding, urine and feces were collected and added to manure storage containers. On weeks 2 and 8 after initiation of the experiment, fresh fecal an...
