About

Geert Opsomer is an Associate Professor at Ghent University in Belgium. His research focuses on dairy cattle health and productivity, particularly in relation to neonatal development and metabolic conditions. Recent articles authored by him explore areas such as telomere length in neonatal dairy calves, the effects of gestational size on calf performance, and the relationship between insulin resistance and metabolic inflammation in transition dairy cows.

Assistant department of Internal Medicine, Reproduction and Population Medicine (30182)

Ghent University’s Faculty of Veterinary Medicine is offering an assistant position in the Department of Internal Medicine, Reproduction and Population Medicine (DI08), focused on bovine herd health. The post is centered on doctoral-level research: at least 50% of the assignment will be devoted to academic research in preparation of a doctoral dissertation on bovine herd health, alongside teaching and service duties. The successful candidate will assist with teaching in ruminant veterinary medicine and herd health, contribute to internal and external departmental services, and take part in night and weekend duties in the Ambulatory Clinic. This makes the position suitable for candidates who want to combine research, education, and hands-on clinical service in a veterinary academic environment. Eligibility highlights include a Master in Veterinary Medicine, preferably with a major in Ruminants. The degree requirement must be fulfilled by the start of the appointment. Candidates with diplomas from outside the EU must provide a certificate of equivalence (NARIC). The department also looks for an interest in academic or project-based research in bovine herd health, with teaching experience or extra training, conferences, or similar activities considered an advantage. Strong teaching and communication skills are required, and fluent Dutch is necessary to serve clinic clients effectively. The appointment is a temporary AAP position at 100% for two years, renewable twice for two additional two-year terms subject to positive evaluation and within the maximum allowed appointment period. The earliest starting date is 15 September 2026. The remuneration follows salary scale AAP3, and Ghent University highlights staff benefits such as training opportunities, paid leave, commuting support, and ecocheques. Applications must be submitted online before 1 September 2026 at 23:59 Brussels time. Required documents include a CV with study results merged into one PDF, a cover letter, and a transcript of the required degree if available. Where applicable, applicants must also upload a certificate of equivalence or proof of having applied for one. For questions about the vacancy, the contact person is Prof. Geert Opsomer.

Genesis of clinical and subclinical endometritis in dairy cows

In brief Clinical and subclinical endometritis are different manifestations of reproductive tract inflammatory disease in dairy cows. This review addresses the genesis of clinical and subclinical endometritis considering metabolic stress, innate immune dysfunction, and shifts in the composition of the uterine microbiota in the postpartum period. Abstract Up to half of dairy cows may develop one or more types of reproductive tract inflammatory disease within 5 weeks after calving. Clinical endometritis (CE) results from uterine bacterial dysbiosis with increased relative abundance of pathogenic bacteria associated with luminal epithelial damage. These bacteria cause endometrial stromal cell lysis, followed by massive polymorphonuclear neutrophil (PMN) migration, and pyogenesis. CE is defined as endometrial inflammation accompanied by purulent discharge. Purulent discharge is not always accompanied by uterine inflammation (being (rarely) vaginitis or (commonly) cervicitis), hence referred to as purulent vaginal discharge (PVD). Subclinical endometritis (SCE) is an asymptomatic uterine disease defined by a threshold of PMN on cytology that is associated with worse reproductive performance; it has not been linked with bacterial dysbiosis. Current evidence suggests that SCE is a result of metabolic and inflammatory dysfunction that impairs innate immune function and the ability of endometrial PMN to undergo apoptosis, necrosis, and ultimately achieve resolution of inflammation. CE and SCE are diagnosed between 3 and 5 weeks postpartum and commonly overlap, but they are considered distinct manifestations of reproductive tract inflammatory disease. This review addresses the genesis of CE and SCE in postpartum dairy cows considering metabolic stress, innate immune dysfunction, and shifts in the composition of the uterine microbiota.
