KATZ, M. L., AND E. N. BERGMAN. Simultaneous measurements of hepatic and portal venous blood ji’ow in the sheep and dog. Am. J. Physiol. 216(4) : 946-952. 1969.-An indicator-dilution method was developed which allowed simultaneous measurement of both portal and hepatic venous blood flow and which consisted of a constant infusion of para-aminohippuric acid (PAH) into a mesenteric vein. The hepat...

In view of the medical, veterinary and economic importance of hydatid disease in India, our study aimed to determine the prevalence and genotypes of Echinococcus present in domestic livestock in India. Out of 21,861 animals examined, cattle were found with the highest prevalence of hydatid cysts (5.10%) followed by buffaloes (3.81%), pigs (0.87%) and sheep (0.075%). Phylogenetic analysis of the...

Abstract Farm diversification is mainly driven by risk mitigation effects and economic gains related to complementarities between production activities. By combining these two aspects, we investigate economies in a sample of French mixed sheep farming systems rank using stochastic dominance criteria. Partially diversified (Sheep-Grass, Sheep-Crop, Sheep-Landless) fully (Sheep-Grass-Crop-Landles...

■ 42. Amend § 558.195 as follows: ■ a. In the table in paragraph (e)(1)(i), in the ‘‘Limitations’’ column, remove ‘‘Do not feed to laying chickens.’’ and in its place add ‘‘Do not feed to laying hens producing eggs for human consumption.’’; ■ b. In the table in paragraph (e)(2)(i), in the ‘‘Limitations’’ column, remove ‘‘Do not feed to cows producing milk for food.’’ and in its place add ‘‘Do n...

A cross-sectional study was carried out to determine the prevalence, species characterization and associated risk factors with Eimeria (E.) in sheep of district Toba Tek Singh from April, 2009 to March, 2010. Of the total 486 faecal samples examined for Eimeria, 209 (43%) were found infected with five species of Eimeria. Amongst the identified species of Eimeria, E. ovinoidalis was the commones...

Enterohaemorrhagic Escherichia coli O157:H7 was first implicated in human disease in the early 1980s, with ruminants cited as the primary reservoirs. Preliminary studies indicated cattle to be the sole source of E. coli O157:H7 outbreaks in humans; however, further epidemiological studies soon demonstrated that E. coli O157:H7 was widespread in other food sources and that a number of transmissi...

The aim of this study was to identify and determine the prevalence of Eimeria species affecting sheep raised extensively in a semiarid region of Brazil. Fecal samples of native sheep were collected during the rainy and dry seasons. The degree of infection was determined by counting oocysts per gram (OPG) of feces, and the morphometric method was used for species identification. Oocysts were fou...

The spontaneous sheep erythrocyte (E) rosette test was used on 340 occasions to measure T cell levels in 28 renal allograft recipients. The E rosette counts were reduced by high-dose steroids but usually returned towards normal under maintenance treatment with azathioprine and low-dose prednisone. Unexpectedly, rejection crises were more often associated with a decrease in E rosettes before ste...

The efficacy of four separate methods of human bone marrow T lymphocyte depletion was assessed, and the effect of T cells and monocytes on in vitro growth of marrow (CFU-GEMM, BFU-E, and CFU-GM) and peripheral blood (BFU-E) hematopoietic progenitors was determined. Extent of T cell depletion was assessed by multiparameter fluorescent cell sorter (FACS) analysis and by functional studies. Cells ...

In sheep, small ruminant lentiviruses cause an incurable, progressive, lymphoproliferative disease that affects millions of animals worldwide. Known as ovine progressive pneumonia virus (OPPV) in the U.S., and Visna/Maedi virus (VMV) elsewhere, these viruses reduce an animal's health, productivity, and lifespan. Genetic variation in the ovine transmembrane protein 154 gene (TMEM154) has been pr...
