Antigen-specific CD4+ and CD8+ T-cell responses in PBMC from pony mares immunized with either native or recombinant zona pellucida vaccines

Joone, C.J. (Carolynne); Schulman, M.L. (Martin); Fosgate, Geoffrey Theodore; Plagis, T.A.; Crafford, Jan Ernst; Gupta, Satish K.; Bertschinger, Hendrik Jan (Elsevier, 2019-03)

Few studies have investigated the cell mediated immune response during zona pellucida-based immunocontraception, despite hypothesized cytotoxic T-cell involvement in ovarian dysfunction associated with these vaccines. This ...
Efficacy and safety of native and recombinant zona pellucida immunocontraceptive vaccines in donkeys

French, Hilari; Peterson, Erik; Schulman, M.L. (Martin); Roth, Robyn; Crampton, Michael; Conan, Anne; Marchi, Silvia; Knobel, Darryn Leslie; Bertschinger, Hendrik Jan (Elsevier, 2020-09)

Feral and semi-feral donkeys are recognised as a problem in some world regions. The main problem associated with uncontrolled donkey populations is habitat degradation and competition for feed resources, especially in arid ...
Fertility suppression of some wildlife species in southern Africa a review

Bertschinger, Hendrik Jan; Caldwell, Peter (Wiley, 2016-09-01)

Generally speaking, southern Africa's wildlife populations in small-to-medium-sized protected game reserves (10,000 65,000 ha) reproduce at rapid rates which often lead overpopulation of certain species. Most commonly these ...
Lack of spatial and behavioral responses to immunocontraception application in African elephants (Loxodonta Africana)

Delsink, Audrey K.; Kirkpatrick, Jay F.; Van Altena, J.J.; Bertschinger, Hendrik Jan; Ferreira, Sam M.; Slotow, Robert (American Association of Zoo Veterinarians, 2013-12)

Opinions are divided as to whether human intervention to control elephant (Loxodonta africana) population growth is desirable, partly because of elephant welfare concerns. Female contraception through immunization with ...
Non-lethal elephant population control methods : summary of the first workshop of the Elephant Specialist Advisory Group of South Africa

Garaï, Marion E.; Bates, Lucy A.; Bertschinger, Hendrik Jan; Delsink, Audrey; Pretorius, Yolanda; Selier, Jeanetta; Zitzer, Heike R. (AOSIS Open Journals, 2018-09-27)

Management interventions are necessary to control elephant numbers within fenced wildlife reserves in South Africa. Use of non-lethal control methods is increasing, but information about their suitability and effects are ...
Ovarian function following immunocontraceptive vaccination of mares using native porcine and recombinant zona pellucida vaccines formulated with a non-Freund's adjuvant and anti-GnRH vaccines

Nolan, Margaret Bethaline; Bertschinger, Hendrik Jan; Roth, Robyn; Crampton, Michael; Martins, I.S. (Isabela); Fosgate, Geoffrey Theodore; Stout, T.A.E. (Tom); Schulman, M.L. (Martin) (Elsevier, 2018-10-15)

An important determinant in the selection of any contraceptive agent is the impact on ovarian function, both in the short and longer term. In this study, ovarian activity was monitored in mares immunised with one of the ...
Porcine zona pellucida vaccine immunocontraception of African elephant (Loxodonta africana) cows : a review of 22 years of research

Bertschinger, Hendrik Jan; Delsink, Audrey; Van Altena, J.J.; Kirkpatrick, Jay F. (AOSIS Open Journals, 2018-07-31)

BACKGROUND : The native porcine zona pellucida (pZP) vaccine has been successfully used for immunocontraception of wild horses, white-tailed deer and approximately 90 zoo species for more than 25 years. OBJECTIVES : To ...
Researching immunocontraceptive vaccines with mares (Equus caballus) as both a target and model for African elephant (Loxodonta africana) cows : a review

Joonè, Carolynne J.; Nolan, Margaret Bethaline; Bertschinger, Hendrik Jan; Schulman, M.L. (Martin) (Elsevier, 2019-08)

A sequence of studies is reviewed that reported the domestic horse (Equus caballus) mare as an appropriate and accessible research platform for recording clinical and laboratory data post-immunisation with anti- GnRH and ...
Serum antibody immunoreactivity and safety of native porcine and recombinant zona pellucida vaccines formulated with a non-Freund’s adjuvant in horses

Nolan, Margaret Bethaline; Schulman, M.L. (Martin); Botha, A.E. (Alma); Human, Anne-Marie; Roth, Robyn; Crampton, Michael C.; Bertschinger, Hendrik Jan (Elsevier, 2019-02)

Commercial and regulatory limitations associated with native porcine zona pellucida (pZP) vaccines formulated with Freund’s adjuvants may be overcome by developing effective recombinant ZP vaccines (reZP) and identifying ...
Use of gonadotropin releasing hormone (GnRH) vaccines for behavioural and reproductive control in managed Asian elephant Elephas maximus and African elephant Loxodonta africana populations

Lueders, Imke; Oerke, A.-K.; Knauf-Witzens, T.; Young, D.; Bertschinger, Hendrik Jan (Wiley, 2019-07)

Because of their size and reproductive anatomy, surgical castration is not a practical option in adult elephants. However, similar to other species in human care, the effects of gonadectomy are desired in specific situations. ...
