“…This situation suggests that in addition to abortions due to a single etiological agent, multiple etiological abortions may be more common than estimated. The introduction mentions that abortion cases in which different etiological agents are detected together have been reported in recent years (De Angelis et al 2022;Ramo et al 2022;Şevik et al 2017a;Şevik et al 2017b;Deniz and Oruc 2023)…”

In this case, multi-etiologic abortion due to Campylobacter spp. and Chlamydia abortus was determined in an aborted sheep fetus sent to Konya Veterinary Control Institute (KVKE) from a sheep farm operating in Aksaray province in 2020. The presence of Campylobacter spp. was determined by the bacterial isolation method. C.abortus was identified by qPCR and immunohistochemistry (IHC) methods. This study should be published in order to emphasize that in the fight against sheep abortions, multi-etiologic abortions involving multiple agents should be taken into consideration in addition to a single etiologic agent, and a multidisciplinary approach should be used in the diagnosis to identify the abortion agents.

Summary Zoonotic diseases, such as brucellosis, Q fever and Rift Valley fever (RVF) caused by Brucella spp., Coxiella burnetii and RVF virus, respectively, can have devastating effects on human, livestock, and wildlife health and cause economic hardship due to morbidity and mortality in livestock. Coinfection with multiple pathogens can lead to more severe disease outcomes and altered transmission dynamics. These three pathogens can alter host immune responses likely leading to increased morbidity, mortality and pathogen transmission during coinfection. Developing countries, such as those commonly afflicted by outbreaks of brucellosis, Q fever and RVF, have high disease burden and thus common coinfections. A literature survey provided information on case reports and studies investigating coinfections involving the three focal diseases. Fifty five studies were collected demonstrating coinfections of Brucella spp., C. burnetii or RVFV with 50 different pathogens, of which 64% were zoonotic. While the literature search criteria involved ‘coinfection’, only 24/55 studies showed coinfections with direct pathogen detection methods (microbiology, PCR and antigen test), while the rest only reported detection of antibodies against multiple pathogens, which only indicate a history of co‐exposure, not concurrent infection. These studies lack the ability to test whether coinfection leads to changes in morbidity, mortality or transmission dynamics. We describe considerations and methods for identifying ongoing coinfections to address this critical blind spot in disease risk management.

In this case, multietiological abortion due to Brucella melitensis (B. melitensis) and Chlamydophila abortus (C. abortus) agents was defined in a sheep abortion. An aborted sheep fetus submitted to Konya Veterinary Control Institute (KVCI) from a sheep farm in Nigde province in Brucella spp. presence was determined by bacterial isolation method and confirmed by slide agglutination test with monospecific A and M sera. C. abortus was detected by real time PCR and immunohistochemistry (IHC) methods. In histopathological examinations, in the lung; hyperemia, hemorrhage and bronchopneumonia, In the heart; in the placenta with degeneration and necrosis of heart muscle cells; hyperemia, hemorrhage, edema, necrosis and mononuclear cell infiltrations were observed. In this study, it was emphasized that in the fight against sheep abortions, multi-etiological abortions involving more than one factor should be taken into consideration, as well as an etiological agent, and it would be appropriate to use multidisciplinary diagnostic methods to determine the abortion factors, thus contributing to the prevention of abortions, which is still an important problem in sheep breeding.
