| contents | Phylogenomics of Brucella abortus isolated from African Buffalo in Kruger National Park: New perspectives on wildlife-cattle disease dynamics. Cossu, Carlo Andrea Garofolo, Giuliano Janowicz, Anna De Massis, Fabrizio Wentzel, Jeanette Ledwaba, Maphuti Betty Sabeta, Claude De Klerk, Lin-Mari Godfroid, Jacques Vergnaud, Gilles van Heerden, Henriette Animals Brucella abortus Buffaloes Phylogeny Brucellosis Animals, Wild Cattle South Africa Disease Reservoirs Parks, Recreational Brucellosis, Bovine Lymph Nodes In South Africa, Brucella abortus biovar 1 is the primary cause of bovine brucellosis, significantly impacting cattle production and trade. Serological studies have revealed brucellosis in African wildlife, complicating control efforts due to limited epidemiological data. In 1977, B. abortus biovar 1 was isolated from an African buffalo fetus in Kruger National Park (KNP), raising speculation that buffalo may serve as reservoir hosts. This study investigated Brucella spp. in free-ranging buffalo in KNP using serological, molecular, and bacteriological methods. Brucella abortus bv 1 was isolated from lymph nodes and spleens of three sub-adult buffalo in 2022, marking the first documented recurrence in 50 years. Phylogenomic analyses revealed connections between buffalo isolates and cattle strains from South Africa and South America, suggesting spillover and shared origins from Europe. Further genomic and epidemiological surveillance is required to clarify the role of buffalo as reservoir hosts for brucellosis. |
