its ability to distinctly stain the capsule. In addition, the stain requires at least 12 months to вЂageвЂ™ in order to develop its metachromatic property, i.e. Although MвЂ™Fadyean PMB staining is the generally-accepted reference standard method for anthrax confirmation by microscopy, quality-controlled PMB has been difficult to obtain commercially since the successful control of anthrax in developed countries. anthracis and is not usually produced by closely related bacteria in the same genus such as B. anthracisвЂ™ complex surface structure and contributes to the pathogenicity and virulence of the bacterium. In 1903, MвЂ™Fadyean established capsule staining with polychrome methylene blue (PMB) as a specific technique to detect B. anthracis for animal anthrax confirmation. Smear stain microscopy meets many of the ASSURED convenience criteria, however little is known about its performance against scientific criteria for the detection of B. It therefore holds great potential value as a field-friendly diagnostic method for anthrax confirmation in low-resource settings. In contrast, smear stain microscopy is a rapid and simple method for detecting B. WHO recommends culture and PCR as the methods of choice for confirmation of anthrax because of their high performance in terms of scientific criteria, but these methods are lacking in convenience criteria, particularly in the context of anthrax-endemic countries. Convenience and scientific criteria are reflected in WHOвЂ™s recommendation of ASSURED tests for developing countries (Affordable, Sensitive, Specific, User-friendly, Rapid and robust, Equipment free, and Deliverable to those who need it). Scientific criteria encompass the ability of a test to distinguish between subjects when the condition under investigation is truly present or absent, while convenience criteria are related to ease or practicality of implementing the test. Tests that perform highly on both scientific and convenience criteria are desirable this is especially true in areas where resources are scarce, and infrastructure is limited. anthracis is easily outcompeted by many other bacterial species. Besides the higher costs associated with culture, the occurrence of anthrax in very remote and challenging environments might mean that samples collected are not viable for culture when they eventually reach the laboratory, as B. For example, culture must be carried out in laboratory facilities equipped at biosafety level (BSL) 2+ or ideally level 3, which are commonly lacking in areas where anthrax is endemic. Culture and (or) PCR are considered to be superior compared to microscopy, but require infrastructure and consumables that few laboratories in developing countries have access to. anthracis in an animal carcass can be achieved by examination of a stained blood smear, or by culture or polymerase chain reaction (PCR). Confirmation of anthrax through detection of B. In many parts of the developing world, underdiagnosis and misdiagnosis are important reasons for limited availability of data on the prevalence, incidence and impact of endemic diseases. Anthrax is a bacterial disease caused by Bacillus anthracis and primarily affects herbivorous mammals, where it is characterised by sudden deaths in otherwise healthy animals. In contrast to emerging diseases, endemic zoonotic diseases like anthrax do not receive the attention needed to control them. Therefore, the control of zoonotic diseases that cause human and animal ill-healthвЂ“as well as losses to livelihoodsвЂ“is important and highly relevant to achieving the Sustainable Development Goals. The livelihoods of the majority of people living in developing countries depend on livestock farming, and it is estimated that about 80% of households in Africa derive all or part of their income from livestock keeping. Zoonotic diseases have a dual and high burden on the health and livelihoods of people, in addition to their impact on animal health and welfare.
