“…The obtained results revealed that the serum phosphate levels were not significantly different between animal groups over the time of experiment. In other similar studies, long time infections with Trichostrongylus rugatus (Pullman et al 1989), T. colubriformis sole (Poppi et al 1985) or together with O. circumcincta (Bown et al 1989) led to decreased phosphate concentrations in blood serum. However, mid to heavy natural infections with Ostertagia spp.…”

Effect of experimental nematode infection on serum mineral concentrations in growing lambs

et al. 2019

The objective of the present study was to determine the possible effect of gastrointestinal nematodes upon serum mineral concentrations of lambs. Twelve male lambs were used. Lambs were randomly assigned to 2 groups (n = 6): Group 1 infected with gastrointestinal nematodes and Group 2 as controls. Lambs of Group 1 were infected with a single dose of 15,000 L 3 larvae of GI nematodes (Haemonchus, Teladorsagia, Trichostrongylus, Cooperia and Oesophagostomum-Bunostomum). Blood samples were collected from the investigated animals individually every 2 weeks. However, the differences in serum macro-minerals (Ca, Mg, P, K, and Na) among groups were not significant. Although the differences in serum macro-minerals among groups were not significant and the iron serum concentration remained unaltered, the gastrointestinal parasitism reduced significantly/substantially the serum copper levels.

“…Similar findings were observed in the present study for the experimental parasitism. Surprisingly, in an experimental infection with Trichostrongylus rugatus of lambs aged 5 months old Ca concentration increased in the infected group, without the authors to give a convincing explanation for it (Pullman et al 1989).…”
