Host-specific gene expression as a tool for introduction success in Naupactus parthenogenetic weevils
(Public Library of Science, 2021-07-30)
Food resource access can mediate establishment success in invasive species, and generalist herbivorous insects are thought to rely on mechanisms of transcriptional plasticity to respond to dietary variation. While asexually ...
Gut microbes limit growth in house sparrow nestlings (Passer domesticus) but not through limitations in digestive capacity
(Wiley Blackwell Publishing, Inc, 2018-03)
Recent research often lauds the services and beneficial effects of host-associated microbes on animals. However, hosting these microbes may come at a cost. For example, germ-free and antibiotic-treated birds generally grow ...
Evaluation of argentinean bird species as amplifying hosts for St. Louis encephalitis virus (Flavivirus, Flaviviridae)
(American Society of Tropical Medicine and Hygiene, 2018-07)
St.Louis encephalitis virus (SLEV) is an emerging human pathogen flavivirus in Argentina. Recently, it has reemerged in the United States. We evaluated the role as amplifying host of six resident bird species and analyzed ...
Identification of a unique gene cluster of Brucella spp. that mediates adhesion to host cells
(Elsevier Science, 2012-01)
Brucella, the causative agent of brucellosis, a major zoonotic disease affecting a broad range of mammals, is a gram-negative bacterium whose virulence is dependent on the capacity to attach and invade different cells of ...
The infra-red (IR) landscape of Triatoma infestans. An hypothesis about the role of IR radiation as a cue for Triatominae dispersal
(Elsevier Science, 2011-12)
This paper presents the infrared (IR) emission spectrum of hosts and habitats of Triatoma infestans in the chaco region of NW Argentina, representing the first attempt to correlate the natural infrared stimulus with the ...
Brucella hijacks host-mediated palmitoylation to stabilize and localize PrpA to the plasma membrane
(American Society for Microbiology, 2018-11)
Brucellaceae are a group of pathogenic intracellular bacteria with the ability to modulate the host response, both at the individual cell level and systemically. One of the hallmarks of the virulence process is the capacity ...
Differences in tolerance to host cactus alkaloids in Drosophila koepferae and D. buzzatii
(Public Library of Science, 2014-02)
The evolution of cactophily in the genus Drosophila was a major cological transition involving over a hundred species in the Americas that acquired the capacity to cope with a variety of toxic metabolites evolved as feeding ...
