Assays to evaluate the transovarial transmission of Anaplasma marginale by Rhipicephalus microplus
(Elsevier, 2022-11)The aim of this study was to evaluate the vectorial competence of Rhipicephalus microplus to transmit Anaplasma marginale transovarially, by analyzing the results of three different but complementary assays. First, larvae ... -
Assessing the genetic diversity of Panicum coloratum var. makarikariense using agro‐morphological traits and microsatellite‐based markers
(2015-11)Panicum coloratum var. makarikariense is a perennial C4 grass native to South Africa with relatively good forage production under limited‐resource conditions. Genetic characterisation and breeding efforts have been scant, ... -
Assessment of habitat suitability for the cattle tick Rhipicephalus (Boophilus) microplus in temperate areas
(Elsevier, 2022-07)The aim of this research was to analyze and model the aptitude of temperate areas to support permanent populations of the cattle tick Rhipicephalus microplus, which is principally distributed in tropical and subtropical ... -
Assessment of the potential utility of different regions of Streptococcus uberis adhesion molecule (SUAM) for mastitis subunit vaccine development
(2017-04)Streptococcus uberis is one of the most prevalent pathogens causing clinical and subclinical mastitis worldwide. Among bacterial factors involved in intramammary infections caused by this organism, S. uberis adhesion ... -
Babesia bovis biological clones and the inter-strain allelic diversity of the Bv80 gene support subpopulation selection as a mechanism involved in the attenuation of two virulent isolates
(Elsevier, 2012-12-21)The virulence phenotype of Babesia bovis subpopulations was evaluated using biological clones derived from the high-virulence BboS2P and the low-virulence BboR1A strain and two original virulent isolates, BboL15 and BboL17, ... -
Babesiosis prevalence in malaria-endemic regions of Colombia
(Wolters Kluwer, 2018-07)Background & objectives: The presence of Babesia spp in humans, bovine cattle and ticks (the transmitting vector) has not been well characterized in Colombia. Babesia infection in humans can be overlooked due to similarity ... -
