The dissemination of C10 cysteine protease genes in Bacteroides fragilis by mobile genetic elements

Thornton, Roibeard F; Kagawa, Todd F; O'Toole, Paul W; Cooney, Jakki C (BioMed Central, 2010)

Background: The C10 family of cysteine proteases includes enzymes that contribute to the virulence of bacterial pathogens, such as SpeB in Streptococcus pyogenes. The presence of homologues of cysteine protease genes in ...
The diversity of fungi in four Irish forest types

O'Hanlon, Richard (University of Limerick, 2011)

Sampling of the macrofungal sporocarps, ectomycorrhizal morphotypes and vascular plants was carried out in 28 plots from four forest types (ash, oak, Scot’s pine, Sitka spruce) between the years 2007 and 2009. A total ...
Effect of breed, plane of nutrition and age on growth, scrotal development, metabolite concentrations and on systemic gonadotropin and testosterone concentrations following a GnRH challenge in young dairy bulls

Byrne, C.J; Fair, Seán; English, A.M; Urh, C; Sauerwein, H; Crowe, M.A; Lonergan, Patrick; Kenny, D.A (Elsevier, 2017)

The onset of puberty in the bull is regulated by the timing of early GnRH pulsatility release from the hypothalamus, which has been demonstrated to be affected by plane of nutrition during calf-hood. The aim of this study ...
Effect of calcium reduction on the properties of half-fat Cheddar-stylecheeses with full salt or half-salt

McCarthy, Catherine M; Wilkinson, Martin G.; Guniee, Timothy P (Elsevier, 2017)

Standard-calcium (SCa) and reduced-calcium (RCa) half-fat (16%) Cheddar-style cheeses with full-salt (1.9%) or half-salt (0.9%) were made in triplicate, ripened for 270 d, and analysed for composition and changes in lactose ...
The effect of dietary n-3 polyunsaturated fatty acids supplementation of rams on semen quality and subsequent quality of liquid stored semen

Fair, Seán; Doyle, D.N; Diskin, M.G; Hennessy, A.A; Kenny, D.A (Elsevier, 2014)

The objective of this study was to examine the effect of dietary n-3 polyunsaturated fatty acid (PUFA) supplementation of rams on semen quality and subsequent sperm function of liquid stored semen. Mature rams of proven ...
The effect of dietary supplementation of algae rich in docosahexaenoic acid on boar fertility

Background: Bacteroides fragilis and Bacteroides thetaiotaomicron are members of the normal human intestinal microbiota. However, both organisms are capable of causing opportunistic infections, during which the environmental ...
Effect of exposing rams to a female stimulus before semen collection on ram libido and semen quality

Fahey, A.G; Duffy, P; Fair, Seán (American Society of Animal Science, 2012)
