  • In birds, these injuries are the result of trichomonosis, a disease spread by a parasite called Trichomonas gallinae . (scienceblogs.com)
  • If the disease progressed as it does in modern birds, by the time the parasite had actually started to erode the jawbone, it would also have thoroughly invaded the animal's gums and riddled its mouth and throat with ulcers (the yellow lumps in the reconstruction painting). (scienceblogs.com)
  • In vivo , l'ASTX n'a eu aucune valeur thérapeutique contre l'infection aiguë par T. cruzi , utilisée seule ou en association avec NFMX. (parasite-journal.org)
  • Why does the pet dog cause human eye infected with parasites? (medicaltrend.org)
  • Human pinworms cannot infect any other animals. (medicalnewstoday.com)
  • CRISPR/Cas9 screens, which have revolutionised human and model organism research, have not yet been implemented in malaria parasites due to the need for more complex CRISPR/Cas9 gene targeting vector libraries. (portlandpress.com)
  • When an infected mosquito bites a human, it can introduce the parasite from its saliva into the person's blood. (who.int)
  • When the mosquito feeds on another human, sporozoites are inoculated and quickly reach the liver and infect hepatocytes. (msdmanuals.com)
  • On the basis of whole-transcriptome analyses, we identify many genes that are expressed in a sex- or life stage-specific manner and characterize the transcriptional landscape of a morphological region with unique biological adaptations, namely, bacillary band and stichosome, found only in whipworms and related parasites. (nature.com)
  • We resolve chromosomal sequences and infer sex chromosome-specific parasite genes and new potential drug targets. (nature.com)
  • Using RNA sequencing data from whipworm-infected mice, we describe the regulated T helper 1 (T H 1)-like immune response of the chronically infected cecum in unprecedented detail. (nature.com)
  • We further demonstrate that these parasites are suitable for high-throughput screening for antimalarial compounds. (nature.com)
  • Emerging parasite resistance to antimalarial medicines and mosquito resistance to insecticides could, if left unaddressed, render some of the current tools ineffective and trigger a rise in global malaria mortality. (who.int)
  • The relative rate of parasite release is defined as the percent of such footprints out of all schizonts injected and incubated into chamber at 37°C for two hours. (biomedcentral.com)
  • The method is used here to show that swelling of schizonts caused by protein-free media inhibits parasite release. (biomedcentral.com)
  • Key parasites and diseases affecting honey bees include Varrora mites, Hive Beetle, and Colony Collapse Disorder. (nps.gov)
  • There is more extensive transfer of parasites and diseases due to rapid travel and commerce. (nps.gov)
  • This parasite is mostly found in children countries where they cause more morbidity and mortali- in kindergartens, institutions or in families with a large ty than other infectious diseases (1,2) . (who.int)
  • Our results imply that Chagas control programmes should consider whether bugs are infected in models of triatomine distribution. (biomedcentral.com)
  • The surface of erythrocytes containing mature parasites bound antibody, but the surface of uninfected cells or cells containing early parasite stages did not react. (ox.ac.uk)
