Meuffels, Janine; Bertschinger, Hendrik Jan; Tindall, Brendan; Pohlin, Friederike; Luther-Binoir, Ilse; Trivedi, Shweta; Boshoff, Christiaan R.; Lueders, Imke (Frontiers Media S.A., 2022-04-27)With the rapid loss of individuals in the wild, semen cryopreservation has gained importance to safeguard the genetic diversity of white rhinoceroses (Ceratotherium simum). For semen collection via electro-ejaculation, ...

Lueders, Imke; Stremme, Christopher (Thieme Gruppe, 2022-04)OBJECTIVE : Here we tested the application of a full mouth speculum to sedated elephants in human care to gain access to the oral cavity, the trachea (bronchi) and esophagus (stomach) and therefore improve diagnostic and ...

Callealta, Isabel; Ganswindt, Andre; Goncalves, Sara; Mathew, Abraham; Lueders, Imke (Wiley, 2018-12)Reports of the vaginal flora of wild cats such as lions or leopards are scarce. The micro‐organisms most commonly found in the vagina of clinically healthy cats are aerobic bacteria such as coagulase‐negative Staphylococcus, ...
