Rumen papillomas in sheep

Veterinary Microbiology, 1985
Out of a sample of 200 rumens from sheep slaughtered in Edinburgh, papillomas were found in 25. They occurred as fibro-papillomas, mostly along the pillar of muscle between the dorsal and ventral rumen, and were often multiple. No inclusion bodies were seen in the lesions or papilloma virus particles on electron microscopy.

Manipulation of fermentation in the rumen

Journal of the Science of Food and Agriculture, 1976
AbstractArtificial saliva (4 litres/day) was infused into the rumen of sheep fed a semi‐purified diet at hourly intervals. Dilution rate and the efficiency of synthesis of microbial protein in vivo were increased. The pattern of rumen fermentation was altered; the molar proportion of propionic acid decreased (32–20%) and acetic acid increased (58–66 ...

Diversity of Phytases in the Rumen

Microbial Ecology, 2006
Examples of a new class of phytase related to protein tyrosine phosphatases (PTP) were recently isolated from several anaerobic bacteria from the rumen of cattle. In this study, the diversity of PTP-like phytase gene sequences in the rumen was surveyed by using the polymerase chain reaction (PCR).

Rumen Overload and Rumenitis in White-Tailed Deer

The Journal of Wildlife Management, 1975
Rumenitis was diagnosed on the basis of histopathology in 30 of 108 white-tailed deer (Odocoileus virginianus) found dead during a severe winter in Saskatchewan. Rumenitis or rumen over- load was considered to be the cause of death of 5 of these deer, and to have contributed to the death of 4 others (8.3 percent of the deer examined).

Xylanase in the Soil and the Rumen

Nature, 1955
IN connexion with experiments on enzymatic decomposition of wheat straw xylan1, the xylanase activity in the soil has been investigated by a method very similar to that of Hofmann2. To 5 gm. of air-dry soil in 50-ml. Erlenmeyer flasks were added 2 ml. of toluene, and, after 10 min., 5 ml. phosphate buffer (pH 6.5) and 5 ml.

Serology of Rumen Bacteroides

Journal of General Microbiology, 1971
SUMMARY: The serological relationships of 26 strains of rumen Bacteroides species comprising Bacteroides ruminicola, B. amylophilus and B. succinogenes were examined using precipitation, agglutination and fluorescent antibody techniques. With precipitation techniques two types of acid-soluble thermostable antigens were detected, a strain-specific ...

Rumen Ciliate Protozoa

1980
Publisher Summary Rumen protozoa were first observed in rumen metabolism. These ciliate protozoa are present in all wild and domesticated ruminants and are of two types: the entodiniomorphid protozoa characterized by the presence of a firm pellicle and the possession of cilia on the peristome and the holotrich protozoa, which are completely covered ...
