The development of a specific, sensitive homologous ovine follicle stimulating hormone (FSH) radioimmunoassay (RIA) is described. The key procedural modifications of basic RIA methods were immunoabsorpt ion of the anti-ovine FSH serum with lutenizing hormone (LH) to improve specificity and adsorption chromatography of the radioiodinated ovine FSH on hydroxyapat i te (HTP) to improve immunoreact...

The mammalian oviduct has long been recognized as an organ essential for successful reproduction. Bovine, ovine, porcine, and equine animal models have offered clear advantages for oviduct study related to gamete physiology, fertilization, and early embryonic development. Livestock species are amenable to surgical alteration of the reproductive tract, estrous cycle manipulation, gamete cryopres...

The first part of this paper presents data concerning our knowledge of uterine proteins during early pregnancy in domestic mammals; the second part gives results of in vitro biochemical studies on embryo-uterine interactions in the ewe. We have developed an in vitro technique of the co-culture of ovine uterine epithelial cells with the blastocyst or its secretory proteins. The effects of a spec...

Placental microvesicles were prepared from ovine placentae and immunoglobulins eluted with 0.5 M glycine buffer pH 2.5. The ability of eluate immunoglobulins to re-associate with isologous (self) and third party acidified microvesicles was tested by ELISA. Ovine placental immunoglobulins re-associated with isologous and third party acidified microvesicles suggesting that at least 2 types of ant...

The IS1311 polymerase chain reaction-restriction endonuclease analysis was used to detect genetic differences among 38 Mycobacterium avium subsp. paratuberculosis (Map) isolates from cattle, sheep, goats and bison from distinct regions of Spain, India and the United States of America (USA). In Spain, all eight bovine isolates, three out of six caprine isolates and one of ten ovine isolates were...

Ovine keratoconjunctivitis was successfully reproduced in lambs under 1 year of age, in four separate transmission trials, by the use of mycoplasma isolates obtained from field outbreaks of ovine infectious keratoconjunctivitis. Mycoplasma isolates used in one of these trials, were identified as M. conjunctivae by means of immunofluorescence. Mycoplasma was isolated from approximately 87% of fi...

INTRODUCTION Ovine dermatophilosis, commonly called ‘dermo’ or ‘lumpy wool’, is an acute or subacute, chronic exudative dermatitis of sheep of all age groups. It causes economic loss to producers through lowered production, lowered wool value, treatment costs, poor-quality skins, restriction of management options such as shearing and death in severe cases. It is caused by a bacterium, Dermatoph...
