  • parasitic
  • Mycoplasmas have evolved from a common gram-positive ancestor ( Razin and Yogev, 1998 ) and the evolutionary path of genome reduction has led to an obligatory parasitic lifestyle which presumably has selected for those bacteria that best manipulate their hosts and make optimal use of their specific niche with a minimal set of genes. (frontiersin.org)
  • For example, Laboulbenia ecitonis G.Blum is a plurivorous species, saying it infects unrelated hosts: it is parasitic to the army ant Eciton quadriglume and it grows quite well on histerid beetles and mites that lodge in the ant colony. (dannyhaelewaters.com)
  • These data were collected to measure the host specificity of parasitic Hymenoptera in the genus Aphelinus that are candidates for introduction from Asia to control the soybean aphid, Aphis glycines, in the United States. (usda.gov)
  • Fungi
  • We considered the host range and distribution of these fungi by sampling diseased ornamental and forest trees and shrubs in Serbia, Montenegro, Bosnia and Herzegovina, spanning a Mediterranean and a Continental climatic region. (up.ac.za)
  • Inoculations showed that the majority of these fungi could also co-infect hosts other than those from which they were isolated. (up.ac.za)
  • strains
  • Representatives from each host-associated population were tested for their ability to colonize gnotobiotic mice, which only rodent strains could accomplish. (unl.edu)
  • To determine the genetic source of these differences, genome sequences from representative strains (from humans, pigs, chickens, and rodents) and genomic microarrays were used to identify host-specific genes tied to ecological success in vivo . (unl.edu)
  • Toxoplasma gondii strains may vary in their pathogenicity in a given host. (alpfmedical.info)
  • Analyzing 15 genes in 580 strains of Typhimurium, they found a high degree of variation and evidence of positive selection and strong evidence that the variation was associated with the particular strains' host specificity. (scienmag.com)
  • bats
  • Both male and female bats were equally likely to be infested and variables of parasite density did not differ amongst host sex for any species. (uno.edu)
  • First, strict virus-host co-evolution is rejected by the existence of five, distantly related bat PV lineages and by the lack of congruence between bats and bat PVs phylogenies. (ehu.es)
  • experiments
  • In laboratory experiments, the levels of parasitism (acceptance) of Ceutorhynchus turbatus Schultze, C . cardariae Korotyaev, C . omissusFall and C . querceti (Gyllenhal) by T . perfectus were not significantly different than of the target host C . obstrictus . (gc.ca)
  • Toxoplasma
  • We are looking for highly motivated PhD students with interest in cellular biology and parasitology who want to work on fundamental biological aspects of the apicomplexan parasite Toxoplasma gondii and its host cell. (uni-muenchen.de)
  • candidates
  • In conclusion, V. parahaemolyticus and A. salmonicida phages show good survival time in marine water, have only a moderated impact on the overall bacterial community structure and the desired specificity for host pathogenic bacteria, being potential candidates for therapy of fish infectious diseases in marine aquaculture systems. (mdpi.com)
  • To ensure that introductions of exotic parasitoids would have minimum impact on non-target species, we tested host specificity of all candidates for introduction. (usda.gov)
  • habitat
  • It seems that the habitat, which is chosen by the host, has a determining effect upon the success of Laboulbeniales. (dannyhaelewaters.com)
  • Now I propose the following suggestion: Laboulbeniales are more host-specific in one habitat than in another, because of differences in host susceptibility to being killed. (dannyhaelewaters.com)
  • In a certain habitat a given host (group) can be more susceptible for its own predators, or more predators may be present in that current habitat. (dannyhaelewaters.com)
  • Say there's a species of Laboulbenia L growing on hosts A and B. Both hosts A and B are equal in providing nutrients and attachment features for L. Host A is present in habitat A and B in habitat B, with a much lower number of predators that attack the host. (dannyhaelewaters.com)
  • adults
  • 1998, 2000) have demonstrated that male village indigobirds ( V. chalybeata ) imprint on the songs of their foster parents as juveniles and mimic the songs of their host species as adults. (indigobirds.com)
  • No-choice host-specificity tests were also conducted with A. tenebrosus adults using potted flowering plants. (fcla.edu)
  • Influence
  • Since sycamore maple is not affected by an epidemic, this could point toward an influence of ash dieback on ash communities, although firm conclusions are not possible because of host preferences and climatic differences. (frontiersin.org)
  • laboratory
  • In North America, the recent discovery of T . perfectus in a C . omissus population suggests that laboratory findings predicting that C . omissus is a preferred host may be the case in the field. (gc.ca)
  • Leaves
  • These included leaves and/or stems of seedlings of 21 hosts, and cut leaves and/or branches of six hosts. (up.ac.za)
  • distribution
  • Microdon myrmicae occurs in waterlogged grassland habitats, mainly of the 'Molinietum' type, resulting in a patchy distribution relative to its host ants. (nerc.ac.uk)
  • bacterial
  • Other bacterial classes responded in contrasting ways to the experimental incubations causing significantly different bacterial communities to develop in response to host phytoplankton species, growth phase and between attached and free-living fractions. (diva-portal.org)
  • analyses
  • The scientists first focused their analyses on Salmonella enterica serovar Typhimurium, which is a leading cause of food poisoning but for which the molecular basis for host preferences is still a mystery. (scienmag.com)
  • broader
  • In total, ten Botryosphaeriaceae species were identified in the Western Balkans and with the exception of Sphaeropsis visci and Phaeobotryon cupressi, which occurred on one host, all the species had a broader host range. (up.ac.za)
  • different
  • Functionally closely related mycoplasma species, which have a highly similar protein domain repertoire, but different hosts could not be separated. (frontiersin.org)
  • The most frequent values of STD* were between 2.5 and 3.5, which shows that the host species more frequently used by Neotropical hard tick species belong to different families or different orders. (conicet.gov.ar)
  • tests
  • Multiple-choice and no-choice tests were conducted at the Florida Department of Agriculture quarantine facility to determine the host specificity of the South American flower bud weevil, Anthonomus tenebrosus Boheman, intended for biological control of the exotic weed tropical soda apple (TSA), Solanum viarum Dunal in Florida, USA. (fcla.edu)
  • genes
  • Following these initial findings, the research team focused on genes for adhesin proteins, which play a key role in the interaction between bacteria and host. (scienmag.com)
  • mice
  • To determine whether the observed host specificity of rodent associated L. reuteri in mice extended to other host-associated lineages, a crossover human experimental trial was conducted. (unl.edu)
  • amongst
  • Cattle and horses are amongst the most-resistant intermediate hosts for clinical toxoplasmosis, in contrast to certain marsupials and new-world monkeys, which are the most susceptible to infection (Dubey and Beattie 1988). (alpfmedical.info)
  • species-specific
  • Although it is frequent to read that PVs co-evolve with their host, that PVs are highly species-specific, and that PVs do not usually recombine, our results suggest otherwise. (ehu.es)
  • effect
  • Manipulating bacteria in this way allowed us to show a cause and effect relationship between a SNP in an adhesin gene and the bacteria's host specificity,' Schifferli said. (scienmag.com)
  • adaptation
  • In a genetic analysis of the KAN-1 virus, we identified further mutations crucial for adaptation to the mammalian host. (uni-marburg.de)
  • This plurivory may have three causes: 1) a similar body chemistry of the cohabiting hosts, 2) incidental infections, and 3) adaptation to exploit other host species. (dannyhaelewaters.com)
