Cycles of Cutaneous leishmaniasis are linked to climate
Cutaneous leishmaniasis occurs in cycles that are related to temperature and the El Niņo Southern Oscillation. Luis Chaves and Mercedes Pascual from the University of Michigan studied monthly data, between 1991 and 2001, of the incidence of cutaneous leishmaniasis in Costa Rica.
Using mathematical models they were able to show that this disease has cycles of approximately 3 y that are related to temperature and indices of the El Niņo Southern Oscillation, including the sea surface temperature. Using such a model they could predict the incidence of cutaneous leishmaniasis up to 12 months ahead, with an accuracy of between 72% and 77%.
Cutaneous leishmaniasis is one of the main emerging diseases in the Americas. As in other vector-transmitted diseases, its transmission is sensitive to the environment, but this is the first study to look at the interannual patterns of cycling of the disease.

Mycobacterium tuberculosis Induces Interleukin-32 Production through a Caspase- 1/IL-18/Interferon-γ-Dependent Mechanism
Synthesis of IL-32, a cell-associated proinflammatory cytokine, was promoted by Mycobacterium tuberculosis and M. bovis, suggesting a role in a role in inflammation and host defense against tuberculosis.
