Administration of antibiotics to ewes at the beginning of the dry- period
(2014)The objective of the present paper is to review the significance of administration of antibiotics at the end of a lactation period/beginning of the dry-period in ewes. During the stage of active involution, there is an ... -
Administration of Vaccines in Dairy Sheep and Goat Farms: Patterns of Vaccination, Associations with Health and Production Parameters, Predictors
(2022)This paper reports findings regarding patterns of vaccine usage in sheep and goat farms, in 325 sheep flocks and 119 goat herds throughout Greece. The objectives of the study were (a) to describe the patterns of vaccine ... -
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 ... -
Association of staphylococcal populations on teatcups of milking parlours with vaccination against staphylococcal mastitis in sheep and goat farms
(2021)There is a paucity of information regarding staphylococcal populations on teatcups of milking parlours in sheep and goat farms. The objectives were to describe the populations of staphylococci on teatcups in milking parlours ... -
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. ... -
Bacterial flora and risk of infection of the ovine teat duct and mammary gland throughout lactation
(2007)We collected samples of teat duct material and mammary secretion from ewes in three farms (flock A, polyparous n = 7; flock B, polyparous n = 6, primiparous n = 4; flock C, polyparous n = 4): 14 samples immediately after ... -
Comparison of the Efficacy of Intramammary or Injectable Antibiotic Administration against Staphylococcal Mastitis in Ewes
(2022)The objectives of the work were (a) to compare the efficacy of two routes for antibiotic administration in the treatment of mastitis in ewes and (b) to assess the potential importance of the timing of the initiation of the ... -
Description and validation of a novel technique to study the bacterial flora of the teat duct of ewes
(2006)We describe a new technique that may be used for studying the bacterial flora of the teat duct in live ewes, and we present evidence regarding its accuracy, safety and repeatability. A sterile, plastic, 20 G catheter is ... -
Detection of cathelicidin-1 in the milk as an early indicator of mastitis in ewes
(2019)The objective of the study was the investigation of the behaviour of cathelicidin-1 in the milk after experimental infection with two prominent bacterial pathogens (experiment 1: Mannheimia haemolytica, experiment 2: M. ... -
Differences in susceptibility to Mannheimia haemolytica-associated mastitis between two breeds of dairy sheep
(2007)We used a Mannheimia haemolytica isolate to study differences in susceptibility to experimental mastitis between two breeds of dairy sheep. The isolate was deposited into the teat duct of Karagouniko (K, n=8) or Frisarta ... -
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 ... -

The effect of experimentally induced subclinical mastitis on the milk yield of dairy ewes
(1999)In each of the two experiments, subclinical mastitis was induced by inoculating both mammary glands of Karagouniko and of Chios-cross ewes with a Staphylococcus epidermidis. After inoculation, the somatic cell counts of ... -
Effects of experimental challenge of ewes with Mannheimia haemolytica on subsequent milk composition
(2008)The objective was to describe the physicochemical changes during the early phase of subclinical mastitis and to associate them with pathological findings. A Mannheimia haemolytica strain was deposited into one teat duct ... -
The effects of inoculation of Mannheimia haemolytica into the teat of lactating ewes
(2005)The objectives of the work described in this paper were: (i) to study the outcome of challenging ewes with Mannheimia haemolytica, at different sites of their teats, (ii) to compare the effects of two different isolates ... -
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 staphylococcal mastitis in bitches: Clinical, bacteriological, cytological, haematological and pathological features
(2007)The objectives of the work were to study the features of experimentally induced canine mastitis and to present hypotheses regarding the pathogenesis of the disease. The tight caudal abdominal mammary gland of six bitches ... -
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 ...
