Application of a semi-dependent latent model in the Bayesian estimation of the sensitivity and specificity of two faecal culture methods for diagnosis of paratuberculosis in sub-clinically infected Greek dairy sheep and goats
(2006)In this study, we compared the frequency of isolation of Mycobacterium avium subsp. paratuberculosis (MAP) from faecal samples grown on Herrold's egg-yolk medium (HEYM) or on Lowenstein-Jensen (LJ) medium and estimated the ... -
Assessment of heavy metal(loid)s contamination risk and grain nutritional quality in organic waste-amended soil
(2020)Studies that evaluate the human health risk of heavy metal(loid)s pollution have not been widely performed for organic waste-amended soils on the Loess Plateau of China. With this respect, we conducted a 3-year field trial ... -
The bacterial flora in the teat duct of ewes can protect against and can cause mastitis
(2007)We studied the possible effects of bacterial populations within the teat duct, in the pathogenesis of ovine mastitis. In experiment I, 32 ewes were allocated into group A (ewes from which we isolated (+++ growth) ... -
Case report: High prevalence rate of ovine mastitis, caused by coagulase-negative staphylococci and predisposed by increased gossypol consumption
(2004)A case of unusually high (>94%) prevalence of mastitis in a flock of dairy sheep, which was caused by coagulase-negative staphylococci (cnS) and associated with increased gossypol consumption, is presented. The animals ... -
Comparison of Three Different Techniques for Subcutaneous Relocation of the Carotid Artery in Small Ruminants
(2001)Three surgical techniques for subcuzaneous relocation of the carotid artery in small ruminants are compared. A total of 25 sheep and seven goats were used and randomly assigned to three groups. In group A (technique A), ... -
A cross-sectional study of the seroprevalence and flock-level factors associated with ovine and caprine brucellosis in southeastern Iran
(2014)This cross-sectional study was conducted to estimate seroprevalence and to identify flock-level factors associated with seropositivity to brucellosis in small ruminants in Kerman province, southeastern Iran. In October-November ... -
An early warning indicator for monitoring infectious animal diseases and its application in the case of a sheep pox epidemic
(2017)We describe an early warning indicator for monitoring infectious diseases. The approach is illustrated with data from a major sheep pox epidemic, which occurred in the Evros prefecture of Greece, from August 2013 until the ... -
Effects of melatonin treatment on follicular development and oocyte quality in Chios ewes - Short communication
(2009)Follicular development and oocyte quality were assessed by laparoscopic observation and in vitro fertilisation, respectively, in melatonin-treated (Group M) and control (Group C) anoestrous Chios ewes (n = 10 in each group). ... -
Enhancement of the transmesothelial resistance of the parietal sheep peritoneum by epinephrine in vitro: Ussing-type chamber experiments
(2005)The peritoneal mesothelium constitutes an ion transport barrier that is taken advantage of in peritoneal dialysis. The aim of this study was to investigate the effects of epinephrine on the electrical transmesothelial ... -
Greek economic crisis and new agrarian dynamics: The example of Eastern Thessaly [Crise économique grecque et nouvelles dynamiques agraires: L’exemple de la Thessalie orientale]
(2015)Eastern Thessaly is a plain bordered by semi-mountainous landscape. The region is home to dairy sheep and goat farming systems exploiting both public and private agro-pastoral resources. The effect of decoupled payments, ... -
Illthrift in suckling lambs secondary to umbilical infections and possible implication of cryptosporidiosis as a risk factor
(2011)Illthrift was observed in 20/60 lambs aged 40-45 days in a dairy sheep flock in Greece. Cryptosporidiosis had been diagnosed and successfully treated with halofuginone lactate a month earlier. Parasitological examinations ... -
MHC class II DRB1 and DQA2 gene polymorphisms in four indigenous breeds of sheep (Ovis aries)
(2016)Major histocompatibility complex (MHC) contains highly polymorphic genes, coding receptors that participate in the immune responses. Information of MHC polymorphism from domestic animals could be used in genetic improvement ... -
A model to account for the consequences of host nutrition on the outcome of gastrointestinal parasitism in sheep: Logic and concepts
(2007)A deterministic, dynamic simulation model is developed to account for the interactions between gastrointestinal parasitism and host nutrition, and predict their consequences on performance and level of parasitism of sheep. ... -
Oocyte pick-up in juvenile lambs affects neither onset of puberty nor their future fertility
(2006)A study was designed to evaluate whether the time of onset of puberty and fertility of young ewe lambs would be affected by oocyte pick-up conducted in single or repeated sessions during the first months of lambs' live. ... -
Ovine β-lactoglobulin at atomic resolution
(2014)The crystal structure of the triclinic form of the milk protein β-lactoglobulin from sheep (Ovis aries) at 1.1Å resolution is described together with a comparison of the triclinic structures of the low-pH bovine and high-pH ... -
Phylogenetic correlation of Greek and Italian orf virus isolates based on VIR gene
(2006)Thirteen orf virus isolates obtained during the time period between 1995 and 2004 from crusted scab lesions of nine sheep and four goats from different geographical areas of Greece and Italy with suspected contagious ecthyma ... -
Potential association between trematode infections and development of pregnancy toxaemia in sheep
