Periparturient relaxation of immunity (PPRI) to parasites in mammals results in higher worm burden and worm egg excretion and may have a nutritional basis.Nippostrongylus brasiliensisre-infected lactating rats fed low-crude protein (CP) diets show an

Parasite vaccines – recent progress and problems associated with their development

Autor: D. L. Redmond, D. P. Knox

Publikováno v: Parasitology. 133:S1-S8

The treatment and prevention of parasitism in both humans and livestock continues to rely almost exclusively on the use of antiparasitic drugs – an approach which has limitations, particularly as reinfection, which occurs rapidly in endemic regions

Further protection studies using recombinant forms of Haemonchus contortus cysteine proteinases

Autor: D. L. Redmond, D. P. Knox

Publikováno v: Parasite Immunology. 28:213-219

Significant levels of protection against Haemonchus contortus have been achieved in sheep by vaccination with a cysteine proteinase-enriched fraction (TSBP) isolated from the gut of adult parasites. Protection is associated with three cathepsin B-lik

Proteins and proteinases in the in vitro released products (IVRP) of the tissue-invasive and lung-dwelling larvae of the pentastomid Porocephalus crotali

Autor: D. P. Knox, J. Riley, A. C. Buckle

Publikováno v: Parasitology. 124:391-399

Pentastomids are arthropod-like parasites which inhabit the respiratory tract of tetrapods and, despite being haematophagous, cause little or no visible pathology. Nymphs (or larvae), belonging to the advanced genus Porocephalus, encyst in the tissue

Development of vaccines against gastrointestinal nematodes

Autor: D. P. Knox

Publikováno v: Parasitology. 120:43-61

Vaccination against complex metazoan parasites has become a reality with the development and registration of recombinant protein-based vaccines against the cattle tick Boophilus microplus and the sheep cestode Taenia ovis. Progress towards the develo

Further immunization and biochemical studies with a protective antigen complex from the microvillar membrane of the intestine of Haemonchus contortus

Autor: S K, Smith, D, Pettit, G F, Newlands, D L, Redmond, P J, Skuce, D P, Knox, W D, Smith

Publikováno v: Parasite Immunology. 21:187-199

Immunization of sheep with a protective antigen complex from the intestinal cells of Haemonchus contortus in Freund's adjuvant stimulated individually variable antibody responses but still conferred significant protection against parasite infection.

Leucine and methionine deficiency impairs immunity to gastrointestinal parasites during lactation

British Journal of Nutrition 109 (2013) 2

Lactating rats reinfected with Nippostrongylus brasiliensis fed low-crude protein (CP) foods show reduced lactational performance and less resistance to parasites compared with their high-CP counterparts. Here, we hypothesised that feeding high-CP fo

Amelioration of the periparturient relaxation of immunity to parasites through a reduction in mammalian reproductive effort

Autor: Jos G. M. Houdijk, Ilias Kyriazakis, P. Sakkas, L. A. Jones, D. P. Knox

Publikováno v: International journal for parasitology. 42(13-14)

The degree of periparturient relaxation of immunity to gastrointestinal parasites has a nutritional basis, as overcoming protein scarcity through increased protein supply improves lactational performance, enhances local immune responses and reduces w
