Association between physical properties of cervical mucus and ovulation rate in superovulated cows
(2011)Possible associations between certain physical properties of cervical mucus (CM) and ovulation rate were studied in 21 superovulated Holstein cows. In CM samples collected at the beginning of estrus (0 h) and in 4 h intervals ... -
Bacteriological and epidemiological findings during examination of the uterine content of ewes with retention of fetal membranes
(2002)We included 92 pairs of ewes with or without retention of fetal membranes in a cohort study of 25 flocks in Southern Greece. We obtained two uterine content samples under aseptic conditions, by introducing a swab into the ... -
Changes in feeding behavior as possible indicators for the automatic monitoring of health disorders in dairy cows
(2008)Changes in short-term feeding behavior of dairy cows that occur with the onset of the health disorders ketosis, acute locomotory problems, and chronic lameness were investigated using data collected during previous ... -
Clinical, bacteriological, cytological and pathological features of teat disorders in ewes
(2007)We describe the features of 13 cases of teat disorders in ewes, as follows: lengthy teats (one case), papilloma infection (two), staphylococcal dermatitis (one), nodules and abscesses (two), teat bites (three), stenosis ... -
Comparison of fluorescence polarization assay, indirect ELISA and competitive ELISA methods for diagnosis of Brucella melitensis-infection in small ruminants
(2004)Three serological tests, the fluorescence-polarization assay (FPA), the indirect ELISA (iELISA) and the competitive ELISA (cELISA), were compared in detecting Brucella melitensis antibodies in 454 serum samples from sheep ... -
Experimentally induced teat stenosis in dairy ewes: Clinical, pathological and ultrasonographic features
(2004)A strain of Staphylococcus chromogenes was introduced into the teat cistern of five ewes, teat inflammation and stenosis being the primary consequences. Initially, the inoculated teats were swollen and warm; later, a hard ... -
Flock-level factors associated with the risk of Mycobacterium avium subsp paratuberculosis (MAP) infection in Greek dairy goat flocks
(2014)In this cross-sectional study we identified flock-level risk factors for Mycobacterium avium subsp. paratuberculosis (MAP) infection, in Greek dairy goat flocks. We collected 1599 milk samples from does that were at the ... -
Isolation of Mycobacterium avium subspecies paratuberculosis from non-ruminant wildlife living in the sheds and on the pastures of Greek sheep and goats
(2008)This study aimed to: (1) investigate whether non-ruminant wildlife interfacing with dairy sheep and goats of four Greek flocks endemically infected with Mycobaclerium avium subspecies paratuberculosis (MAP) harboured MAP ... -
Isolation of Mycoplasma bovis from bovine clinical mastitis cases in Northern Greece
(2007)Mycoplasnia bovis was detected in 18/219 (8.2%) quarter milk samples collected from cases of bovine clinical mastitis in Northern Greece between November 1997 and March 1999. The cases occurred in 2/37 (5.4%) of the herds ... -
A novel flexible method to split feeding behaviour into bouts
(2009)Before meal patterns can be analysed properly, a biologically relevant meal criterion must be determined in order to group short-term feeding behaviour into meals. Existing methodologies are based on modelling of the ... -
Occurrence, virulence genes and antibiotic resistance of Escherichia coli O157 isolated from raw bovine, caprine and ovine milk in Greece
(2009)The examination of 2005 raw bovine (n = 950), caprine (n = 460) and ovine (n = 595) bulk milk samples collected throughout several regions in Greece for the presence of Escherichia coli serogroup O157 resulted in the ... -
OCCURRENCE, VIRULENCE GENES AND ANTIMICROBIAL RESISTANCE OF ESCHERICHIA COLI O157 IN BOVINE, CAPRINE, OVINE AND PORCINE CARCASSES IN GREECE
(2011)One thousand and two hundred carcasses (620 bovine, 130 caprine, 230 ovine and 220 porcine) from several slaughterhouses throughout Greece were examined for the presence of Escherichia coli O157 after evisceration and ... -
Persistent efficacy of long-acting moxidectin for control of trichostrongylid infections of sheep
(2009)The objective was to evaluate long-acting moxidectin (Cydectin (R) 2% LA for sheep) against trichostrongylids in sheep. We performed a blocked, parallel, controlled clinical trial. We included 45 ewe-lambs, allocated into ... -
Prevalence of Coxiella burnetii antibodies in bulk milk and blood serum and associations with reproductive indices in cow dairy herds of Central Northern Greece
(2011)For the first time in Greece, we investigated the prevalence of Coxiella burnetii antibodies in milk and sera from dairy cattle herds located at central and northern parts of the country. Eighty herds were initially voluntary ... -
Prevalence of Leptospira species among farmed and domestic animals in Greece
(2003)A total of 1527 serum samples from pigs, goats, sheep, cattle and dogs in Greece were examined by the microscopic agglutination test and 11.8 per cent of them had antibodies against one or more Leptospira serovars at titres ... -
Reproductive efficiency of three estrus synchronization schemes comprising fixed-time insemination in dairy cows
(2000)The objective of this field trial was to compare the odds of pregnancy at 25 days (P25) and at 60 days (P60), of embryonic death (ED) between 25 and 60 days, and of non-pregnant cows returning to heat 20-25 days after ... -
Shiga toxin-producing Escherichia coli in Central Greece: prevalence and virulence genes of O157:H7 and non-O157 in animal feces, vegetables, and humans
(2013)In Greece, Shiga toxin-producing Escherichia coli (STEC) have only been sporadically reported. The objective of this study was to estimate the prevalence of STEC and Escherichia coli O157:H7 in farm animals, vegetables, ... -
Toll Like Receptor 9 (TLR9) Polymorphism G520R in Sheep Is Associated with Seropositivity for Small Ruminant Lentivirus
(2013)Infectious diseases of sheep are of major economic importance causing direct and indirect losses. Among the major sheep infectious agents are Small Ruminant Lentivirus, Chlamydophila abortus and Mycobacterium avium subsp. ... -
