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) ...
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 ...
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 ...
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 ...
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 ...
Presence of subepithelial lymphoid nodules in the teat of ewes
(2007)
A total of 87 clinically healthy ovine teats were examined bacteriologically (by scraping the mucosa) and histologically. Teats examined were those of lactating mammary glands with no bacteria isolated (n = 23); of mammary ...
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 ...
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 ...
