SETTING Rubaga Division, Kampala, Uganda. OBJECTIVE To use polymerase chain reaction (PCR) based regions of difference (RD) analysis to study the species diversity of Mycobacterium tuberculosis complex isolates from a community-based sample of tuberculosis (TB) patients from Rubaga and to perform long sequence polymorphism (LSP) analysis to further(More)
Although there are over 90 serotypes of Streptococcus pneumoniae, antimicrobial resistance is predominantly found in a limited number of serotypes/serogroups, namely 6, 9, 14, 19 and 23. There is no compelling mechanism to account for this restriction. We aimed to determine whether serotypes commonly associated with drug resistance have higher(More)
In recent years the population structures of many apicomplexan parasites including Plasmodium spp., Toxoplasma gondii and Cryptospordium parvum have been elucidated. These species show a considerable diversity of population structure suggesting different strategies for transmission and survival in mammalian hosts. We have undertaken a population genetic(More)
Wildlife, especially Cape buffalo (Syncerus caffer), are thought to act as a reservoir for many of the important tick-borne pathogens of cattle. In this study, we have determined the prevalence of the most significant tick-borne haemoparasites in wildlife (buffalo, impala, eland and bushbuck) as well as in cattle grazing inside and neighbouring Lake Mburo(More)
BACKGROUND Brucellosis is one of the most common zoonotic infections globally. Lack of knowledge about brucellosis may affect the health-seeking behavior of patients, thus leading to sustained transmission in these communities. Our study assessed knowledge and perceptions of brucellosis among pastoral communities adjacent to Lake Mburo National Park (LMNP),(More)
During a period of eight months, the carcases of 16,800 slaughter cattle were inspected at a city abattoir in Uganda. Eighty-seven of them had tuberculosis-like lesions and tissue samples were cultured. Only 17 cultures yielded acid-fast bacilli; 11 of them were confirmed as Mycobacterium bovis and six as non-tuberculous mycobacteria (NTM). GenoType(More)
The 'Muguga cocktail' live vaccine, delivered by an infection and treatment protocol, has been widely deployed in Eastern, Central and Southern Africa to protect cattle against East Coast fever, caused by Theileria parva. The vaccine contains 3 component stocks (Muguga, Serengeti-transformed and Kiambu 5). In a previous study, parasites from vaccinated and(More)
The development of sensitive PCR-based species-specific diagnostics and parasite genotyping methods offer the opportunity to provide important and detailed information on the infection dynamics of tick-borne disease. In this study we have exploited such tools to investigate the infection kinetics and parasite diversity within Theileria parva in a single(More)
BACKGROUND Previous studies have shown that Mycobacterium tuberculosis (MTB) Uganda family, a sub-lineage of the MTB Lineage 4, is the main cause of tuberculosis (TB) in Uganda. Using a well characterized patient population, this study sought to determine whether there are clinical and patient characteristics associated with the success of the MTB Uganda(More)
We have identified a clonal complex of Mycobacterium bovis isolated at high frequency from cattle in Uganda, Burundi, Tanzania, and Ethiopia. We have named this related group of M. bovis strains the African 2 (Af2) clonal complex of M. bovis. Af2 strains are defined by a specific chromosomal deletion (RDAf2) and can be identified by the absence of spacers 3(More)
