ABSTRACT
O objetivo do presente estudo foi analisar a dissimilaridade fenotípica de amostras populacionais de três linhagens de éguas Crioulas, uruguaia (La Invernada), argentina (Cardal) e chilena, para caracteres morfológicos, apontando as características de maior variância intra e entre as diferentes linhagens que são passíveis de seleção. Foram avaliadas 22 características morfológicas de 113 éguas da linhagem uruguaia "La Invernada", 38 argentinas "Cardal" e 73 chilenas puras, totalizando 224 éguas de cria pertencentes à raça Crioula. Para determinação das variáveis lineares e de perímetro, foi utilizada fita métrica, prumo, paquímetro e hipômetro. Verificou-se variabilidade nas características morfológicas entre as três linhagens (P<0,05), incluindo as características lineares altura, perímetro de tórax e perímetro de canela (P<0,01), consideradas de caráter impositivo para fins de registro. Maior variação fenotípica foi observada nas éguas da linhagem chilena em relação aos outros dois grupos genéticos (P<0,01). As características morfológicas altura garupa, perímetro rostral pescoço, comprimento metatarso, largura garupa, profundidade do tórax, comprimento dorsal pescoço e comprimento do corpo foram passíveis de seleção entre as éguas Crioulas pertencentes às linhagens argentina (Cardal), uruguaia (La Invernada) e chilena. Em conclusão, não há homogeneidade entre as linhagens estudadas, o que identifica a diversidade entre as linhagens de éguas Crioulas estudadas.(AU)
The aim of the study was to analyze the phenotypic dissimilarity of morphological characteristics of three strains of Criollo mares, Uruguian (La Invernada), Argentine (Cardal), and Chilena, pointing to the characteristics of higher variance within and among the different strains that are selectable. We evaluated 22 morphological characteristics of 113 mares of the Uruguaian line, 38 Argentines and 73 pure Chilean, totaling 224 breeding mares belonging to the criollo breed. For the determination of the linear and perimeter variables, a metric tape, plumb, pachymeter and hypometer were used. There was variability in the morphological characteristics between the three strains (P<0.05), including the linear characteristics of height, chest circumference and perimeter of cinnamon (P<0.01), considered as taxation for registration purposes. Higher phenotypic variation was observed in the mares of the Chilean line in relation to the other two genetic groups (P<0.01). The morphological characteristics of height croup, rostral perimeter neck, metatarsal length, croup width, chest depth, dorsal neck length, and body length were the selectable characteristics among the breeding mares belonging to the Argentine (Cardal), Uruguaian (La Invernada) and Chilena strains. In conclusion, there is no homogeneity between the studied strains, which identifies the diversity among the lines of Criollo mares studied.(AU)

The Authors show the results obtained through the study of a Paracoccidioides strain isolated from a penguin in the Uruguaian Antartide by GEZUELE et al. (1989). From the fecal mater it was isolated a fungus which was recently considered as a new species of the genus Paracoccidioides--P. antarcticus. However, the mycological and immunochemical studies including the demonstration of the 43 kDa glycoprotein by immunodiffusion test, SDS-PAGE and immunoelectrophoresis disclosed that such strain is similar to P. brasiliensis. Other studies, based on molecular taxonomy, including karyotyping, are the only tools to confirm the possibility of such strain to be a variant of P. brasiliensis. The Authors report the epidemiological significance of that finding and suggest a review in the knowledge of the ecological "niche" of P. brasiliensis.
