Article Synopsis
- Assisted reproductive technologies are being used to help save endangered rhinoceros species, including the Southern and Northern white rhinoceroses.
- Researchers successfully generated in vitro blastocysts from these species, with 22 blastocysts from the Northern white and 19 from the Southern white rhinoceros.
- This innovative approach aims to address the urgent need for reproductive strategies as rhinoceros populations decline, especially since the Northern white rhino is functionally extinct.
Article Synopsis
- ARTs, initially used for domestic and lab animals, are now being applied in wildlife conservation to enhance genetic management and increase population numbers.
- The use of ARTs in wildlife raises ethical concerns that haven't been thoroughly examined yet.
- This study introduces an ethical analysis framework based on the Ethical Matrix (EM) and uses ovum pick-up (OPU) procedures for the northern white rhinoceros as a case study to guide similar assessments for other endangered species.
Article Synopsis
- Peste des petits ruminants (PPR) is a viral disease affecting goats and sheep, significantly impacting livelihoods and livestock trade in Africa, the Middle East, and Asia; wild artiodactyls are also susceptible to the PPR virus (PPRV), posing risks to endangered species.
- A study conducted in Kenya and Tanzania from 2015-2016 found 19.7% of sampled wild artiodactyls were seropositive for PPRV, with African buffalo and Grant's gazelle populations showing seroprevalence rates of 12.0% and 1.1%, respectively, in 2018-2019.
- Findings indicate that PPRV infection
Zoonotic pathogens are among the most important causes of ill health all over the world. The presence of these pathogens in free ranging baboons may have significant implications for humans. In Kenya, the encroachment of wildlife habitats has led to increased interaction between humans and wildlife especially non-human primates.

Assisted reproductive technologies (ARTs) can make a difference in biodiversity conservation. Their application, however, can create risks and raise ethical issues that need addressing. Unfortunately, there is a lack of attention to the topic in the scientific literature and, to our knowledge, there is no tool for the ethical assessment of ARTs in the context of conservation that has been described.

We assessed the knowledge, practices and attitudes towards spotted fever group rickettsioses (SFGR) and Q fever amongst local residents in Laikipia and Maasai Mara in Kenya. A semi-structured questionnaire was administered to a total of 101 respondents including 51 pastoralists, 17 human health providers, 28 wildlife sector personnel and 5 veterinarians.

The diseases are widely reported amongst international travellers returning from most sub-Saharan Africa with fever, yet their importance in local populations largely remains unknown. Although this has started to change and recently there have been increasing reports of the diseases in livestock, ticks and humans in Kenya, they have not been investigated in wildlife.
