Machado, Adelina; Rito, Teresa; Ghebremichael, Solomon; Muhate, Nuelma; Maxhuza, Gabriel; Macuamule, Custodia; Moiane, Ivania; Macucule, BaltazarBovine tuberculosis is a zoonotic disease with largely unknown impact in Africa, with risk factors such as HIV and direct contact with animals or consumption of Mycobacterium bovis infected animal products. In order to understand and quantify this risk and design intervention strategies, good epidemiological studies are needed. Such studies can include molecular typing of M. bovis isolates. The aim of this stud...
Mycobacterium tuberculosis causing tuberculous lymphadenitis in Maputo, Mozambique
Viegas, Sofia Omar; Ghebremichael, Solomon; Massawo, Leguesse; Alberto, Matos; Fernandes, Fabíola Couto; Monteiro, Eliane; Couvin, DavidBACKGROUND: The zoonosis bovine tuberculosis (TB) is known to be responsible for a considerable proportion of extrapulmonary TB. In Mozambique, bovine TB is a recognised problem in cattle, but little has been done to evaluate how Mycobacterium bovis has contributed to human TB. We here explore the public health risk for bovine TB in Maputo, by characterizing the isolates from tuberculous lymphadenitis (TBLN) ca...
Epidemiology of Mycobacterium bovis infection in wild boar (Sus scrofa) from Po...
Santos, Nuno; Neves, Margarida Correia; Ghebremichael, Solomon; Källenius, Gunilla; Svenson, Stefan; Almeida, VirgílioTuberculosis has been diagnosed in wild boar (Sus scrofa) in several European countries during the last decade; however, almost no information has been reported to date for Portugal. This study aimed to investigate tuberculosis in wild boar in Portugal through characterization of Mycobacterium bovis infection and identification of disease risk factors. Tissue samples were obtained from hunted wild boar during t...
