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 ... -
Effects of lamb sucking on the bacterial flora of teat duct and mammary gland of ewes
(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
(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. ... -
Teat disorders predispose ewes to clinical mastitis after challenge with Mannheimia haemolytica
(2006)In order to study the effects of sheep teat disorders on the protection of the mammary gland, we used a Mannheimia haemolytica isolate, which did not cause clinical mastitis when deposited into intact teats. In the first ... -
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 ... -
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 ... -
Use of lincomycin to control respiratory infections in lambs: Effects on health and production
(2006)The efficacy of lincomycin to control respiratory infections in lambs was assessed in two trials. In trial 1, 72 lambs with active mycoplasmal pneumonia were allocated as follows: lambs in group T2 were treated with ...
