Continued Continued Cetacean phylogeny in relation to Brucella infections. The phylogenetic tree was constructed based in cytochrome B sequences as reported previously (May-Collado and Agnarsson, 2006). The species are named according to the current extant taxonomic rank. The color squares represent the different cetacean families as follows: Balaenopteridae + Eschrichtiidae (black), Neobalaenidae (light green), Balaenidae (red), Kogiidae + Physeteridae (purple), Ziphiidae (yellow), Platanistidae (light pink), Iniidae (pink), Pontoporiidae (green) Lipotidae (brown), Phocoenidae (gray) Monodontidae (light blue), and Delphinidae (blue). The acronyms used for locating the oceanic distribution are the following: Africa (Af), Amazon River (Azr), America (Am), Antarctic Ocean (An), Arabic Peninsula (Arp), Arctic Ocean (Ar), Atlantic (A), Austral Sea (Ats), Australia (Aus), Baja California Gulf (Bacg), Black Sea (Bs), Central (C), Central America (Ce), Chile (Ch), Continental (Co), East (E), Europe (Eu), Ganges River (Gar), Indian Ocean (In), Indochina Sea (Ich), Indus River (Inr), Japan (Ja), La Plata River (Lapr), Littoral (L), Madeira river (Mar), Magellan Strait (Ms), Mediterranean Sea (Mes), Mexico (Mx), New Zealand (Nz) North (N), Orinoco river (Orr), Pacific (P), Pe (Peru), South (S), West (W), Worldwide (World), and Yangtze river (Yr). Population: The acronyms for the cetacean population size correspond to: least concern (LC), threatened (T), conservation dependent (CD). The number of serologically positive cetaceans in a given test/total number of cetaceans tested is indicated as +/N°. The acronyms for the serological assays are: iELISA (I), cELISA-I (II), cELISA-II (III), aELISA (IV), gELISA (V), agELISA (VI), C’ELISA (VII), Western Blot (VIII), Dot Blot (IX), FPA (X), IF (XI), Complement fixation (XII), Rose Bengal agglutination (XIII), Card agglutination test (XIV), Rivanol agglutination (XV), 2-mercaptoethan agglutination (XVI), PCR (XVII). Under “Isolation” refers to Brucella isolated from tissues of cetaceans. The MLVA-16 corresponds to A1, A2, B, C1, and P1. The Brucella isolates not fully identified or only identified as B. ceti are indicated as Br and Bc, respectively.
