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) ...
Teat lesions predispose to invasion of the ovine mammary gland by Mannheimia haemolytica
(2007)
Teat lesions, produced in ewes by an experimental chapping procedure, were found to facilitate experimental infection with Mannheimia haemolytica, as assessed by observations on infection of the teat skin, teat duct and ...
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. ...
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 ...
Transmission of Mannheimia haemolytica from the tonsils of lambs to the teat of ewes during sucking
(2011)
Objective of the work was to study whether Mannheimia haemolytica may be transmitted from the mouth of the lambs into the teat of the dam during sucking. We compared bacterial populations within the teat duct and milk 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 ...
Presence of sub-epithelial lymphoid tissues in the teat of ewe-lambs and adult ewes
(2007)
In the first part of the study, 24 clinically healthy teats from non-lactating ewe-lambs were examined bacteriologically and histologically. No bacteria were isolated from any of these teats; lymphocytes were observed in ...
