Genome evolution within the alpha Proteobacteria: why do some bacteria not possess plasmids and others exhibit more than one diferent chromosome?
(Elsevier, 1998)Animal intracellular Proteobacteria of the alpha subclass without plasmids and containing one or more chromosomes are phylogenetically entwined with opportunistic, plant-associated, chemoautotrophic and photosynthetic ... -
Genome typing, histopathology, and evolution of BPV30, a novel Xipapillomavirus type isolated from Bovine papilloma in Costa Rica
(Elsevier B.V, 2022-02-13)Xipapillomavirus includes a group of viruses almost exclusively reported in both beef cattle and dairy breeding, in which they induce papillomatosis and occasionally malignant tumors. Bovine papillomaviruses (BPVs) infection ... -
Globally invasive, withdrawing at home: Aedes albopictus and Aedes japonicus facing the rise of Aedes flavopictus
(Springer, 2016)It has been suggested that climate change may have facilitated the global expansion of invasive disease vectors, since several species have expanded their range as tempera tures have warmed. Here, we present results from ... -
GTPases of the Rho subfamily are required for Brucella abortus internalization in nonprofessional phagocytes
(The American Society for Biochemistry and Molecular Biology, Inc., 2001-11-30)Members of the genus Brucella are intracellular -Proteobacteria responsible for brucellosis, a chronic disease of humans and animals. Little is known about Brucella virulence mechanisms, but the abilities of these ... -
