  • It will keep the infective larval stage viable for the infection of their definitive host. (cdc.gov)
19901
  • 1992 and bigger snails subjected to possess lower infection amounts than smaller sized snails from the same age group (Niemann and Lewis 1990 Circulating snail haemocytes play an integral role in immune system monitoring (Oliveira et al. (immune-source.com)
Identification1
  • Details for: A Guide for the identification of the snail intermediate hosts of schistosomiasis in the Americas. (who.int)
Frogs1
  • Angiostrongyliasis is suspected based on a history of ingesting potentially contaminated material, including land snails, slugs, or transfer hosts such as certain land crabs, frogs, toads, or freshwater prawns or shrimp. (msdmanuals.com)
Populations1
  • The frequency of host antibiotic use often determines the strength of this selection, and changing patterns of antibiotic use can generate many types of behaviors in the population dynamics of resistant and sensitive bacterial populations. (bioone.org)
Prevalence1
  • Between the extremes of disease 'control' (reduction in incidence and/or prevalence) and 'eradication,' several intermediate levels of impact on diseases may be described. (cdc.gov)
Occurrence1
  • Concerning the latter two snails, there is no report confirming the occurrence of O. glabra in the Czech Republic, but P. columella was observed in several biotopes [ 21 ]. (biomedcentral.com)

Pila1
  • Pila leopordivillensis, an African snail, was introduced from Taiwan. (applesnail.net)
Juvenile2
  • Juvenile snails are 1.2-2.2 mm in size at birth (India Biodiversity Portal 2018). (usgs.gov)
  • 1992 we OSI-420 counted spread haemocytes in little juvenile snails and in bigger adults and established R/S phenotypes in those two size classes. (immune-source.com)
Vulnerable1
  • Among known fact is that snail size can impact infectivity prices: some strains of are vulnerable as juveniles but resistant as adults (Richards et al. (immune-source.com)
Mammalian1
  • 7 mm to 12 mm by 2 mm to 3 mm) reside in the biliary and pancreatic ducts of the mammalian host, where they attach to the mucosa. (cdc.gov)
Common intermediate host1
  • a common intermediate host of Opisthorchis spp. (cdc.gov)
Occurs1
  • So in addition to definitive hosts where sexual reproduction occurs, they also require an intermediate host. (cdc.gov)
