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) ... -
Detection of cathelicidin-1 in the milk as an early indicator of mastitis in ewes
(2019)The objective of the study was the investigation of the behaviour of cathelicidin-1 in the milk after experimental infection with two prominent bacterial pathogens (experiment 1: Mannheimia haemolytica, experiment 2: 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 ... -
Differential quantitative proteomics study of experimental Mannheimia haemolytica mastitis in sheep
(2019)Objective was the differential quantitative proteomics study of ovine mastitis induced by Mannheimia haemolytica; clinical, microbiological, cytological and histopathological methods were employed for confirmation and ... -
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 ... -
Gastrointestinal trichostrongylosis can predispose ewes to clinical mastitis after experimental mammary infection
(2017)Objective was to study, in an experimental model, the possible role of gastrointestinal nematode infection in predisposing ewes to mastitis during the lactation period. Twenty-four ewes (A or B [n = 12]), free from nematode ... -
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. ... -
Mastitis in sheep - The last 10 years and the future of research
(2015)Bacterial mastitis is a significant welfare and financial problem in sheep flocks. This paper reviews the recently published literature, including publications that highlight the significance and virulence factors of the ... -
Pregnancy toxaemia as predisposing factor for development of mastitis in sheep during the immediately post-partum period
(2015)Objective of the work was to evaluate the potential predisposing role of pregnancy toxaemia in development of mastitis in the immediately post-partum period. Ewes were allocated in subgroups A1 or A2 (with pregnancy toxaemia) ... -
Presence of cathelicidin-1 in milk as an indicator of the severity of mammary infection in ewes
(2021)Aims: The importance of cathelicidin-1 as an indicator of the severity of mammary infection in ewes. Background. Mastitis is an important disease of sheep, affecting their health and welfare. Objective: The association of ... -
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 proteomics in the study of mastitis in ewes
(2019)The objective of this review is to describe the usage and applicability of proteomics technologies in the study of mastitis in ewes. In ewes, proteomics technologies have been employed for furthering knowledge in mastitis ...
