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 ...
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 ...
Isolation of Arcanobacterium pyogenes from the scrotal skin and the prepuce of healthy rams or from rams with testicular abnormalities
(2006)
In a field study, samples were obtained from the scrotal skin and the preputial cavity of 48 rains and examined bacteriologically. Bacteria were isolated from all skin samples and from 90% of preputial cavity samples. The ...
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 ...
