Brucellosis is a zoonotic disease, caused by some species within the Brucella genus. The primary and secondary objectives of this cross-sectional study were to determine the seroprevalence of Brucella antibodies in humans and cows and identify risk factors for exposure to Brucella spp. among people in Shahjadpur sub-district, Bangladesh. Twenty-five villages were randomly selected from the 303 milk-producing villages in the sub-district. We randomly selected 5% of the total households from each village. At each household, we collected demographic information and history of potential exposure to Brucella spp. in humans. In addition, we collected serum from household participants and serum and milk from cattle and tested to detect antibodies to Brucella sp. Univariate analysis was performed to detect associations between seropositivity and demographics, risk factors, and behaviors in households. We enrolled 647 households, 1313 humans, and 698 cows. Brucella antibodies were detected in sera from 27 household participants (2.1%, 95% confidence interval [95%CI]: 1.2-2.9%). Eleven (1.6%, 95%CI 0.6-2.4%) cows had detectable Brucella antibodies in either milk or serum. About half (53%) of the 698 cows exhibited more than one reproductive problem within the past year; of these, seven (2%) had Brucella antibodies. Households with seropositive individuals more frequently reported owning cattle (78% vs. 32%, P < 0.001). Despite a low prevalence of Brucella seropositivity in the study, the public health importance of brucellosis cannot be ruled out. Further studies would help define Brucella prevalence and risk factors in this region and nationally.

BACKGROUND: Brucellosis is a neglected bacterial zoonotic disease with substantial economic impact on households. Pastoral communities are a potential risk group due to their way of life being closely interlinked with their large livestock herds. METHODOLOGY: A semi-structured questionnaire survey was conducted in households in the pastoral Afar and Somali (SRS) regions. All households had people and animals serologically tested for brucellosis. Questions were related to husbandry, consumption habits, and knowledge-attitude-practice towards the disease and zoonoses. Descriptive statistics and logistic analysis were performed to assess potential risk factors for having households with positive humans and/or animals. RESULT: 647 households were included in the survey. Herd brucellosis prevalence was 40.3 % (15.9-86.3 % in Afar; 4-72.2 % in SRS). Over half (56.3 %) of the households in Afar and 41.8 % in SRS had at least one human reactor. Nearly a quarter of the households (22.8 %), recalled abortions in goats in the last 12 months, whereas 52.5 % and 50.3 % recalled stillborn in all species and membrane retentions respectively. All respondents drank raw milk and discarded animal afterbirths in the direct surroundings with minimal protection. Risk factors for animal reactors were goat herd size, and goat abortion. There was no identified risk factor for having human reactors in households. None of the households knew about brucellosis. CONCLUSION: Although being endemic in Afar and SRS, Brucellosis is not known by the pastoralists. Brucellosis control programs will have to be tailored to the pastoral context, accounting for their mobility, large, multi-species herds and habits.

BACKGROUND: Brucellosis is widespread in Ethiopia with variable reported prevalence depending on the geographical area, husbandry practices and animal species. However, there is limited information on the disease prevalence amongst pastoral communities, whose life is intricately linked with their livestock. METHODOLOGY: We conducted an integrated human-animal brucellosis sero-surveillance study in two adjacent pastoral regions, Afar and Somali region (SRS). This cross-sectional study included 13 woredas (districts) and 650 households. Blood samples were collected from people and livestock species (cattle, camel, goats and sheep). Sera were analyzed with C-ELISA for camels and shoats (sheep and goats), with I-ELISA for cattle and IgG ELISA for humans. Descriptive and inferential statistics analyses were performed. RESULTS: A total of 5469 sera were tested by ELISA. Prevalence of livestock was 9.0% in Afar and 8.6% in SRS (ranging from 0.6 to 20.2% at woreda level). In humans, prevalence was 48.3% in Afar and 34.9% in SRS (ranging from 0.0 to 74.5% at woreda level). 68.4% of all households in Afar and 57.5% of households in SRS had at least one animal reactor. Overall, 4.1% of animals had a history of abortion. The proportion of animals with abortion history was higher in seropositive animals than in seronegative animals. Risk factor analysis showed that female animals were significantly at higher risk of being reactors (p = 0.013). Among the species, cattle had the least risk of being reactors (p = 0.014). In humans, there was a clear regional association of disease prevalence (p = 0.002). The older the people, the highest the odds of being seropositive. CONCLUSION: Brucellosis is widespread in humans and animals in pastoral communities of Afar and SRS with the existence of geographical hotspots. No clear association was seen between human and particular livestock species prevalence, hence there was no indication as whether B. abortus or B. melitensis are circulating in these areas, which warrants further molecular research prior to embarking on a national control programs. Such programs will need to be tailored to the pastoral context.

Anthrax is a zoonotic disease caused by the bacterium Bacillus anthracis that is considered endemic in Bangladesh, where cases among animals and people have been reported almost annually since 2009. Contaminated by-products from animals are suspected to play a role in transmission to people, but minimal information is known on the supply-chain of these potentially contaminated products. Between April 2013 and May 2016, we conducted a qualitative study in 17 villages located in 5 districts in Bangladesh, which had experienced suspected anthrax outbreaks. The study explored how by-products from suspected animal cases were collected, discarded, processed, distributed, and used by people. We conducted open-ended interviews, group discussions, and unstructured observations of people's exposure to animal by-products. The practice of slaughtering acutely ill domestic ruminants before they died was common. Respondents reported that moribund animals were typically butchered, and the waste products were discarded in nearby rivers, ditches, bamboo bushes, or on privately owned land. Regardless of health status before death, very few carcasses were buried, and none were incinerated or burned. The hides were reportedly used to make wallets, belts, shoes, balls, and clothing. Discarded bones were often ground into granular and powder forms to produce bone meal and fertilizer. Therefore, given anthrax is endemic in the study region, livestock with acute onset of fatal disease or found dead with no known cause of death may be an anthrax case and subsequently pose a health risk to those involved in the collection and processing of the carcass, as well as the end-user of these products. Improved bio-security practices and safe carcass disposal measures could reduce the risk of human exposure, but resource and other constraints make implementation a challenge. Therefore, targeting at-risk animal populations for vaccination may be the most effective strategy to reduce anthrax outbreaks, protect the supply chain, and reduce the risk of exposure to B. anthracis.

Purpose of Review: Here, we discuss the current needs and priorities for mycetoma control and prevention, highlight lessons learned from leprosy and podoconiosis, and motivate an urgent need to accelerate progress toward reducing the burden of mycetoma in endemic areas. Recent Findings: In 2015, the World Health Assembly (WHA) added mycetoma, a progressively debilitating disease caused by fungi and bacteria, to the World Health Organization (WHO) list of priority neglected tropical diseases (NTDs). Designation of other diseases as NTDs has raised awareness, enabled global partnerships, and advanced the capacity to combat disease through integrated programming. Although key mycetoma etiologic agents have been identified, many questions remain and mycetoma may similarly benefit from NTD designation. Summary: In collaboration with experts at WHO and elsewhere, we formed a global mycetoma working group to connect partners from a variety of sectors and specialties. We envision that this group will evolve into a formalized partnership that can prioritize strategic planning, advocacy, and research needs, identify funding sources, and coordinate activities related to mycetoma and other NTDs affecting the skin. The experiences gained from other NTDs can help to guide the global mycetoma working group's activities to better address the goals set forth in the WHA resolution.

Naturally occurring anthrax disproportionately affects the health and economic welfare of poor, rural communities in anthrax-endemic countries. However, many of these countries have limited anthrax prevention and control programs. Effective prevention of anthrax outbreaks among humans is accomplished through routine livestock vaccination programs and prompt response to animal outbreaks. The Centers for Disease Control and Prevention uses a 2-phase framework when providing technical assistance to partners in anthrax-endemic countries. The first phase assesses and identifies areas for improvement in existing human and animal surveillance, laboratory diagnostics, and outbreak response. The second phase provides steps to implement improvements to these areas. We describe examples of implementing this framework in anthrax-endemic countries. These activities are at varying stages of completion; however, the public health impact of these initiatives has been encouraging. The anthrax framework can be extended to other zoonotic diseases to build on these efforts, improve human and animal health, and enhance global health security.
