The epidemiology of bacterial zoonoses in pastoral and dairy cattle in Cameroon, Central Africa.

Zoonoses Public Health 2021 Jun 15. Epub 2021 Jun 15.

Royal (Dick) School of Veterinary Studies and The Roslin Institute, University of Edinburgh, Easter Bush, Midlothian, UK.

Previous work identified that bacterial zoonoses (Brucella species, Coxiella burnetii and Leptospira hardjo) were present in Cameroonian pastoral cattle. To assess the characteristics of this zoonotic risk, we analyse seroprevalence of each pathogen and the associated management, herd and environmental factors in Cameroonian pastoral and dairy cattle. Cross-sectional samples included pastoralist herds in the Northwest Region (NWR n = 750) and Vina Division (VD n = 748) and small holder dairy herds in the NWR (n = 60). Read More

Recurrent Fevers and Neuro-ophthalmic Disorders in a Mathematical Genius.

Neuroophthalmology 2021 1;45(2):131-138. Epub 2021 Mar 1.

Department of Internal Medicine, Wright State University School of Medicine, Dayton, Ohio, USA.

Horner's syndrome coexisting with an ipsilateral fourth cranial nerve palsy is a rare occurrence and likely localises to pathology in the cavernous sinus. One such case may have occurred in the 18 century affecting the renowned mathematician Leonhard Euler. A review of his biographies, eulogies, and three finely detailed facial portraits suggest that these two neuro-ophthalmic conditions, along with visual loss and a decades-long intermittent febrile illness, may have been the result of an orbital cellulitis and septic cavernous sinus thrombosis, from an underlying chronic brucellosis infection.

Diagnosis and Surgical Treatment of Human Brucellar Spondylodiscitis.

J Vis Exp 2021 May 23(171). Epub 2021 May 23.

Department of Spine Surgery, First Affiliated Hospital of Xinjiang Medical University;

Brucellar spondylodiscitis (BS) is the most prevalent and significant osteoarticular presentation of human Brucellosis, which is commonly manifested in pastoral communities. It is difficult to differentially diagnose and usually leads to irreversible neurologic deficits and spinal deformities. The initial diagnosis of BS is based on clinical findings and radiographic assessments, and the confirmed diagnosis should be established by the isolation of Brucella species from the blood and/or the standard tube agglutination test.

4 Attfield Close, Clyde, New Zealand. Electronic address:

Brucellosis caused by Brucella abortus and Brucella melitensis is endemic in the Republic of Azerbaijan but a complex mix of fiscal, political and technical constraints has impeded regulatory authority decision making for adoption of a sustainable national control programme. This paper reports a series of epidemiologic studies of the disease in animals and humans which we conducted between 2009 and 2020. A preliminary study and a subsequent larger study using vaccination of all non-pregnant female sheep and goats of breeding age and all females between 3 and 8 months with conjunctival Rev1 vaccine both recorded significant reduction in small ruminant seroprevalences.
