Trematode infections in pregnant ewes can predispose to mastitis during the subsequent lactation period

Mavrogianni, V. S.; Papadopoulos, E.; Spanos, S. A.; Mitsoura, A.; Ptochos, S.; Gougoulis, D. A.; Barbagianni, M. S.; Kyriazakis, I.; Fthenakis, G. C. (2014)

Objective was to investigate if trematode infections predispose ewes to mastitis and/or metritis. We used 80 trematode-infected ewes: primigravidae in group P-A and multigravidae in M-A remained untreated, primigravidae ...

Subclinical mastitis changes the patterns of maternal-offspring behaviour in dairy sheep

Gougoulis, D. A.; Kyriazakis, I.; Papaioannou, N.; Papadopoulos, E.; Taitzoglou, I. A.; Fthenakis, G. C. (2008)

Subclinical mastitis was induced by inoculating one mammary gland in dairy ewes (n = 8) with a Staphylococcus simulans isolate; control ewes (n = 4) were included. The milk yield of inoculated glands decreased (P < 0.001), ...

Diagnostic significance of behaviour changes of sheep: A selected review

Gougoulis, D. A.; Kyriazakis, I.; Fthenakis, G. C. (2010)

Sheep welfare is the combination of subjective and objective (qualitative and quantitative) aspects of the conditions of life of animals, including health and disease, behaviour. husbandry and management; thus, it is a ...

Patterns of maternal-offspring behaviour of dairy sheep and potential association with mammary health

Gougoulis, D. A.; Kyriazakis, I.; Mavrogianni, V. S.; Fragkou, I. A.; Skoufos, J.; Tzora, A.; Taitzoglou, I. A.; Kokoli, A. N.; Fthenakis, G. C. (2007)

Behaviour during lactation and its relationship with mammary health was investigated in 12 dairy ewes (six with single lambs and six with twins) for 42 d after lambing. Behavioural recordings were made. Samples of teat ...

Effects of lamb sucking on the bacterial flora of teat duct and mammary gland of ewes

Gougoulis, D. A.; Kyriazakis, I.; Tzora, A.; Taitzoglou, I. A.; Skoufos, J.; Fthenakis, G. C. (2008)

We aimed (i) to determine differences in bacterial flora of teat duct and mammary gland of ewes before and after suckling, (ii) to evaluate factors potentially affecting those. We collected samples of teat duct material ...

The induction of lymphoid follicle-like structures in the ovine teat duct following experimental infection with Mannheimia haemolytica

Fragkou, I. A.; Dagleish, M. P.; Papaioannou, N.; Cripps, P. J.; Boscos, C. M.; Ververidis, H. N.; Orfanou, D. C.; Solomakos, N.; Finlayson, J.; Govaris, A.; Kyriazakis, I.; Fthenakis, G. C. (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. ...

Differences in susceptibility to Mannheimia haemolytica-associated mastitis between two breeds of dairy sheep

Fragkou, I. A.; Skoufos, J.; Cripps, P. J.; Kyriazakis, I.; Papaioannou, N.; Boscos, C. M.; Tzora, A.; Fthenakis, G. C. (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 ...

Effects of experimental challenge of ewes with Mannheimia haemolytica on subsequent milk composition

Fragkou, I. A.; Solomakos, N.; Dagleish, M. P.; Cripps, P. J.; Papaioannou, N.; Boscos, C. M.; Ververidis, H. N.; Billinis, C.; Orfanou, D. C.; Govaris, A.; Kyriazakis, I.; Fthenakis, G. C. (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 ...
