Association of subclinical mastitis prevalence with sheep breeds in Greece
(2018)The objective of the research described in this Research Communication was to describe potential associations of subclinical mastitis with sheep breeds in Greece. A countrywide survey (2198 ewes in 111 farms) was performed. ... -
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 ... -
Consequences of reduced vitamin A administration on mammary health of dairy ewes
(2013)The study was carried out in Mytilene breed dairy ewes, which were allocated into two groups, 2 months before their first mating. All animals were given a diet based on dried alfalfa hay and concentrate compound feed with ... -
Differential quantitative proteomics study of experimental Mannheimia haemolytica mastitis in sheep
(2019)Objective was the differential quantitative proteomics study of ovine mastitis induced by Mannheimia haemolytica; clinical, microbiological, cytological and histopathological methods were employed for confirmation and ... -

Evaluation of efficacy of a biofilm-embedded bacteria-based vaccine against staphylococcal mastitis in sheep—A randomized, placebo-controlled field study
(2019)Our objective was to evaluate the efficacy of a vaccine against staphylococcal mastitis in 5 dairy sheep farms, with 316 ewes in the vaccinated (V) group and 307 in the control (C) group studied throughout a lactation ... -
Experimental study for evaluation of the efficacy of a biofilm-embedded bacteria-based vaccine against Staphylococcus chromogenes-associated mastitis in sheep
(2019)Although coagulase-negative staphylococci are the primary aetiological agents of subclinical mastitis in ewes, there is little information regarding vaccination against that infection. The objective of this study was to ... -
Extensive countrywide field investigation of subclinical mastitis in sheep in Greece
(2018)The objectives of this work were (1) to investigate prevalence of subclinical mastitis, (2) to identify etiological agents involved, and (3) to study factors potentially predisposing ewes to subclinical mastitis. Milk ... -
Field evidence for association between increased gastrointestinal nematode burden and subclinical mastitis in dairy sheep
(2019)The objective of the present study was to study, under field conditions, potential associations between gastrointestinal nematode parasitism and subclinical mastitis in ewes during the lactation period. Faecal and milk ... -
Gastrointestinal trichostrongylosis can predispose ewes to clinical mastitis after experimental mammary infection
(2017)Objective was to study, in an experimental model, the possible role of gastrointestinal nematode infection in predisposing ewes to mastitis during the lactation period. Twenty-four ewes (A or B [n = 12]), free from nematode ... -
The induction of lymphoid follicle-like structures in the ovine teat duct following experimental infection with Mannheimia haemolytica
(2010)The objectives of this study were to investigate the early stages of experimental infection of the ovine mammary gland with Mannheimia haemolytica and to identify the lymphocyte subsets accumulating at the teat duct. M. ... -
Interactions between parasitic infections and reproductive efficiency in sheep
(2015)This review article summarises the many reports in the literature, confirming that, in sheep, parasitic infections can adversely affect reproductive efficiency; examples, which refer to all parts of the reproductive cycle ... -
Isolation and characterization of Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) from milk of dairy goats under low-input farm management in Greece
(2020)The presence of Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) in raw milk is a challenge for veterinarians and public health professionals. In this study, we investigated the presence and clonality of ... -
Phylogenetic analysis of strains of Orf virus isolated from two outbreaks of the disease in sheep in Greece
(2012)Background: Although orf is endemic around the world, there are few descriptions of Orf virus strains and comparisons of these strains. We report the sequence and phylogenetic analysis of the partial B2L gene of Orf virus ... -
Predisposing factors for bacterial mastitis in ewes
(2019)Objective of this review paper is the appraisal of predisposing factors for bacterial mastitis in ewes. Factors that predispose ewes to mastitis can be classified into non-animal-related factors (environmental and ... -
Pregnancy toxaemia as predisposing factor for development of mastitis in sheep during the immediately post-partum period
(2015)Objective of the work was to evaluate the potential predisposing role of pregnancy toxaemia in development of mastitis in the immediately post-partum period. Ewes were allocated in subgroups A1 or A2 (with pregnancy toxaemia) ... -
Principles of Mastitis Treatment in Sheep and Goats
(2011)This article indicates the principles for treatment of mastitis in ewes/does and explains the reasons why treatment may occasionally fail. It presents the principles for administration of antimicrobial agents at drying off ... -
Role of staphylococci in mastitis in sheep
(2019)Staphylococci have been isolated from various sites of the body of healthy sheep, as well as from many infections of those animals, the main one being mastitis. The objective of this review is to appraise the importance ...
