The activity of three glycosidases (β-Ν-acetyloglucosaminidase, α-mannosidase, and β-galactosidase) in the follicular fluid and in the maturation medium affects bovine oocyte maturation
(2016)We studied the role of follicular fluid's (FF) glycosidase (α-mannosidase [α-ΜΑΝ], β-Ν-acetyloglucosaminidase [NAGASE], β-galactosidase [β-GAL]) activity during IVM of bovine oocytes. Oocytes were allocated into two groups ... -
Antimicrobial Agent Susceptibility and Typing of Staphylococcal Isolates from Subclinical Mastitis in Ewes
(2019)Objective was to study susceptibility to antimicrobial agents of 142 staphylococcal isolates from subclinical mastitis in ewes. In total, 41.5% of these were resistant and 5.6% multidrug resistant. More coagulase-negative ... -
Bayesian estimation of the true prevalence of paratuberculosis in Hungarian dairy cattle herds
(2020)Paratuberculosis is a chronic incurable disease caused by Mycobacterium avium subsp. paratuberculosis (MAP), which leads to extensive economic losses on dairy farms, and may also pose serious public health risk to the ... -
Bayesian evaluation of three serological tests for the diagnosis of bovine brucellosis in bangladesh
(2019)We evaluated the performance of three serological tests – an immunoglobulin G indirect enzyme linked immunosorbent assay (iELISA), a Rose Bengal test and a slow agglutination test (SAT) – for the diagnosis of bovine ... -
Bluetongue in small ruminants: An opinionated review, with a brief appraisal of the 2014 outbreak of the disease in Greece and the south-east Europe
(2015)Bluetongue is an arthropod-borne viral disease of ruminants, especially of sheep, caused by Bluetongue virus, which belongs to the genus Orbivirus of the family Reoviridae and is classified into 26 antigenically distinct ... -
Bovine colostrum supplementation improves bone metabolism in an osteoporosis-induced animal model
(2021)Osteoporosis is characterized by bone loss. The present study aims to investigate the effects of bovine colostrum (BC) on bone metabolism using ovariectomized (OVX) and orchidec-tomized (ORX) rat models. Twenty-seven-week-old ... -
Clostridium perfringens foodborne outbreak during an athletic event in northern Greece, June 2019
(2019)Background: Food safety is a major public health consideration during athletic events. On 27 June 2019, the Hellenic National Public Health Organization was notified of a cluster of gastroenteritis cases among athletes of ... -
Colistin resistant mcr genes prevalence in livestock animals (Swine, bovine, poultry) from a multinational perspective. a systematic review
(2021)The objective of this review is to collect and present the results of relevant studies on an international level, on the subject of colistin resistance due to mcr genes prevalence in livestock animals. After a literature ... -
Collagen fibril diameter distribution affects permeability of ligament tissue: A computational study on healthy and injured tissues
(2020)Background and objective In a vascular or hypovascular tissues, elements required for maintaining tissue functions are recruited through diffusion, which is highly related with the permeability of the extracellular matrix ... -
Comparison of biuret and refractometry methods for the serum total proteins measurement in ruminants
(2017)Background: Determination of serum total protein concentration is commonly performed by the biuret method. Refractometric measurement is a faster and less expensive alternative but its accuracy has not been determined in ... -
Cost-benefit analysis of intervention policies for prevention and control of brucellosis in India
(2018)Background: Brucellosis is endemic in the bovine population in India and causes a loss of US$ 3·4 billion to the livestock industry besides having a significant human health impact. Methods: We developed a stochastic ... -
Dam's infection progress and within-herd prevalence as predictors of Mycobacterium avium subsp. paratuberculosis ELISA response in Danish Holstein cattle
(2016)Understanding the primary routes of transmission of Mycobacterium avium subsp. paratuberculosis (MAP) is pivotal to manage the pathogen in cattle herds. MAP is transmitted both vertically and horizontally, and both the ... -
Developmental competence of heat stressed oocytes from Holstein and Limousine cows matured in vitro
(2021)The negative effects of heat stress on dairy cattle's fertility have been extensively studied, but the relevant knowledge for beef cattle is rather limited. The aims of this study were to investigate the effects of HS ... -
Early embryo losses, progesterone and pregnancy associated glycoproteins levels during summer heat stress in dairy cows
(2021)Objectives of this study were to characterize the effects of heat stress on pregnancy associated glycoproteins (PAG) and progesterone and its involvement in embryo survival. In trial 1, blood samples collected from days ... -
Effect of chitosan coating on the shelf life of ready-to-eat bovine meatballs and the control of Listeria monocytogenes growth on their surface during refrigeration storage
(2019)Edible chitosan coating on the surface of ready-to-eat (RTE) bovine meatballs was evaluated for its effect on their shelf life and the control of Listeria monocytogenes at 5 °C. L. monocytogenes was inoculated onto the ... -
