Low Prevalence of Mycobacterium bovis in Tuberculosis Patients, Ethiopia

Emerging Infectious Diseases, 2020
An estimated 17% of all tuberculosis cases in Ethiopia are caused by Mycobacterium bovis. We used M. tuberculosis complex isolates to identify the prevalence of M. bovis as the cause of pulmonary tuberculosis. Our findings indicate that the proportion of

Naturally Occurring CodY Variants Alter Ligand Binding, DNA Target Affinity, and Virulence in Clostridioides difficile

Molecular Microbiology, EarlyView.
Single amino acid substitutions in the global regulator CodY can alter nutrient sensing and virulence regulation in Clostridioides difficile. We show that the CodY(Y146N) and CodY(V58A) variants display altered ligand binding and reduced promoter binding, leading to derepression of toxin regulatory pathways and increased virulence in vivo.

Cow Milk Risk Factors Associated With Bacterial Contaminations Along Dairy Value Chain in Lushoto and Handeni Districts, Tanzania

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Milk and milk products are important sources of nutrients to human and animals, but due to its physicochemical characteristics and nutritional value, it serves as an excellent medium for growth of microorganisms. Most of smallholder dairy farmers have no training on livestock husbandry and milk handling practices.

Ocorrência e caracterização da tuberculose em caprinos leiteiros criados no estado de Pernambuco

Pesquisa Veterinária Brasileira, 2012
Acreditou-se durante muito tempo que a espécie caprina era resistente à infecção por Mycobacterium bovis, porém tal hipótese foi desconsiderada quando relatos da enfermidade surgiram em vários países.

Bovine tuberculosis history as a risk factor for recurrence in English cattle herds experiencing a breakdown

Veterinary Record, Volume 198, Issue 12, Page e533-e542, 13–27 June 2026.
Abstract Background Bovine tuberculosis (TB) threatens cattle farming in England. Supplementing tuberculin skin testing with the interferon‐gamma blood test during TB incident (breakdown) management can enhance diagnostic sensitivity. We aimed to identify herds at greater risk of recurrence depending on their recent TB history to inform targeted ...
