Four Equus asinus were challenged with promastigotes of Leishmania chagasi Cunha & Chagas, 1937, and followed up for 12 months. They were observed by means of direct testing for promastigotes in smears and culture of peripheral blood, fragments from inferior lip, bone marrow, spleen and liver and the immunological assays ELISA and TRALd. The post-necropsy histological examination demonstrated a...

φ f (x) =   f (x)− f (x0) x−x0 , x , x0 f ′(x0), x = x0. Now, by the differentiability of f at x0, we have lim x→x0 x∈X\{x0 } φ f (x) = lim x→x0 x∈X\{x0 } f (x) − f (x0) x − x0 = f (x0) = φ f (x0). This proves that φ f is continuous at x0. Moreover, (1.1) holds for all x ∈ X by definition of φ f . ((1.1) is clearly true when x , x0. When x = x0, both sides of (1.1) are zero.) Therefore (ii) ...
