Background: Leptospirosis is suspected to be a major cause of illness in rural Tanzania associated with close contact with livestock. We sought to determine leptospirosis prevalence, identify infecting Leptospira serogroups, and investigate risk factors for leptospirosis in a rural area of Tanzania where pastoralist animal husbandry practices and sustained livestock contact are common.
Methods: We enrolled participants at Endulen Hospital, Tanzania.
Background: Brucellosis is a neglected zoonosis endemic in many countries, including regions of sub-Saharan Africa. Evaluated diagnostic tools for the detection of exposure to Brucella spp. are important for disease surveillance and guiding prevention and control activities.

We also evaluated the OCT's overall utility in its application to a multisectoral outbreak response.
Methods: We collected data on direct costs associated with a human and animal anthrax outbreak in Songwe Region (December 2018 to January 2019) using structured questionnaires from key-informants.
The control of brucellosis across sub-Saharan Africa is hampered by the lack of standardized testing and the use of tests with poor performance. This study evaluated the performance and costs of serological assays for human brucellosis in a pastoralist community in northern Tanzania. Serum collected from 218 febrile hospital patients was used to evaluate the performance of seven index tests, selected based on international recommendation or current use.

However, across studies, the relationships between dominance rank, social behaviours and adrenal responses can be inconsistent. Differences in the relationship between rank and glucocorticoids may be due to the relative costs of social status, and the relative frequencies of social stressors and potential coping mechanisms.

This risk is particularly important for great apes, given their close phylogenetic relationship with humans. Areas of high human density or intense research and ecotourism activities expose apes to a high risk of disease spillover from humans.

Design: Prospective unblinded study.
Setting: Regional tertiary care Veterans Affairs medical center.
We have treated several patients who required major, proximal extremity amputations despite a patent infrainguinal in situ saphenous vein bypass graft. To determine those factors predisposing to such paradoxical limb loss, we studied a group of 45 patients who underwent 48 in situ, femorodistal bypass grafts for tissue necrosis and who maintained a patent graft throughout the perioperative period. Within this cohort, we compared two distinct subgroups: Group I, whose limbs (n = 8) ultimately required a major proximal amputation; Group II, whose limbs (n = 40) emerged with a viable foot and did not require a major amputation.
