Different lines of evidence used to delimit species in ticks : a study of the South American populations of Amblyomma parvum (Acari: Ixodidae)
(2016-10)The goal of this work was to combine different lines of evidence besides that of molecular markers to delimit species in ticks when the molecular data are not totally congruent. Two groups (Argentina, Brazil) of South ... -
Differential immune response to two Staphylococcus aureus strains with distinct adaptation genotypes after experimental intramammary infection of dairy cows
(Elsevier, 2022-11)The aim of this study was to evaluate and compare the ability of two S. aureus strains with different adaptation genotypes (low and high) to the bovine mammary gland (MG) to establish an intramammary infection (IMI) and ... -
Dinámica de Diaporthe caulivora en fuentes de inóculo: rastrojos y malezas, y períodos de protección frente al cancro del tallo de soja
