The domestic animal, known as a main reservoir of Coxiella burnetii, is susceptible to the occurrence of coxiellosis, which can lead to abortions in domestic animals, causing significant economic damage and posing risks to human health. Therefore, the purpose of this study is to investigate C. burnetii as the causative agent of Q fever in abortion samples of small ruminants in southeastern Iran. This study was conducted between 2020 and 2021 in Zarand city, located in Kerman province (southeast Iran). In this study, 50 abomasum swab samples of aborted sheep and goat fetuses were collected and analyzed using molecular methods to identify C. burnetii. The results revealed that 26% (n: 13) of the collected abortion samples were infected with C. burnetii. Among the positive samples, two (50%) belonged to goat abortion samples while 11 (23.9%) belonged to sheep abortion samples. This study demonstrates that C. burnetii is one of the causes of abortion in small ruminants in southeastern Iran. It is recommended to pay more attention to C. burnetii in domestic animals due to its significant economic impact on livestock and its potential implication for human health in Iran.

Introduction: Abortion and euthanasia are still one of the greatest bioethical challenges. Previous studies have shown that there are differences in attitudes towards these issues depending on socio-demographic characteristics and socio-cultural environment (country of residence). As part of the scientific research project EuroBioMed, we compared the attitudes of students from three Mediterranean countries towards abortion and euthanasia and examined them from the perspective of Mediterranean bioethics.
