Ovine chlamydiosis, also known as enzootic abortion of ewes (EAE) or ovine enzootic abortion (OEA), is caused by the bacterium Chlamydophila abortus. Chlamydial abortion typically occurs in the last 2–3 weeks of pregnancy with the appearance of stillborn lambs and inflamed placentas. However, infection can also result in the delivery of full-term stillborn lambs or weak lambs that do not surviv...
In this study, we tried explant method and a combination of explant-enzymatic method for the extraction of Mesenchymal Stem Cells from ovine umbilical cord tissue wharton’s jelly. The isolated and culture expanded cells expressed strong alkaline phosphatase activity and they were shown to form colonies. The Mesenchymal Stem Cells showed positive for CD44 and negative for CD34 surface markers by...
1. The effect of infusion of ovine prolactin was studied in anaesthetized dogs pretreated with bromocryptine to reduce the release of endogenous prolactin. 2. Prolactin, injected intravenously and also directly into one kidney, resulted in a 12--18% increase in glomerular filtration rate (GFR) by both kidneys. 3. This increased GFR was not associated with any demonstrable changes in whole-kidne...
Long-term ovine fibroblast cultures contain replicative-competent lentiviruses in a latent form. This in vitro phenomenon, never described previously for lentiviruses, was clearly demonstrated by activating the expression of latent viruses with various inducing cell treatments, some of which were efficient in inducing endogenous retroviruses or latent herpesviruses. Activated lentiviruses were ...
The transmission, control and the relationship between Dicrocoelium dendriticum and its definitive (sheep and cattle) and intermediate (molluscs and ants) hosts under natural and experimental conditions are described. Eleven species of molluscs and four of ants were found infected with larval D. dendriticum in León province, north-west Spain. Infected ants were observed between April and Novemb...
background the genus-listeria has two pathogenic species namely, listeria monocytogenes and listeria ivanovii. of these, l. monocytogenes is a well-known cause of abortion, encephalitis and septicaemia in man and animals. listeria ivanovii is an animal pathogen and in rare cases causes human infection. contamination of ovine carcasses during the slaughter and processing is a major risk for food...
the growth hormone (gh) gene is a candidate for growth trait in farm animals and plays an important role in growth metabolism. growth hormone can contribute in growth metabolism when it's receptor (ghr) are on cells target. the single nucleotide polymorphism was occurred in gh and ghr genes and that associated with carcass traits in lori-bakhtiari sheep breed with using pcr-sscp. in this r...
to determine the protein polymorphism of ovine transferrin association with carcass economic traits in makoei, blood samples of 576 (male and female) lambs with two types of venoject (edta anticoagulant containing and non-anticoagulant containing). plasma and serum were then separated and kept in the central laboratory of animal science depaartment in karaj at -20°c. the research was conducted ...
