Leishmania are vector-borne protozoan intracellular parasites causing disease in humans and sometimes dogs in 98 countries across 5 continents with an estimated 0.2-0.4 million, and 0.7-1.2 million, annual new cases of visceral and cutaneous leishmaniasis, respectively. More than 20 species of Leishmania cause disease in humans most with complex transmission cycles involving a diversity of zoonotic reservoirs and different sand fly vector species. The disease spectrum in humans includes simple cutaneous to disseminated or metastasised mucocutaneous lesions to life threatening visceral involvement. Against transmission, there are no human vaccines, animal culling is controversial and vector control is complex or/and predominantly unsustainable. However novel control methods are becoming available for field evaluation.

Environmental Mycobacterium and bovine tuberculosis

Members of the Mycobacterium genus cause a range of diseases in animals and humans including bovine tuberculosis due to M. bovis that is one of the most economically largest animal health problems in the UK farming industry, and costing the tax payer over £500m in the past decade. The European badger is known to be involved in the transmission cycle in the UK and Ireland, and one route of transmission between these hosts is thought to be via environmental contamination with M. bovis. More generally, environmental reservoirs of pathogenic and immunomoderating Mycobacteria spp are poorly studied despite their suggested role in inhibiting human BCG efficacy.
