| antimicrobial peptides from the skin secretions of the new world frogs lithobates capito and lithobates warszewitschii (ranidae). | taxonomic revisions within the anuran family ranidae have established the genus lithobates that currently comprises 49 species of frogs from the new world. peptidomic analysis, using reversed-phase hplc with on-line detection by electrospray mass spectrometry, has led to the identification of multiple antimicrobial peptides in norepinephrine-stimulated skin secretions of the north american frog lithobates capito and the central american frog lithobates warszewitschii. structural characterization ... | 2009 | 19635516 |
| antimicrobial peptide defenses of the tarahumara frog, rana tarahumarae. | populations of the tarahumara frog rana tarahumarae have decreased markedly in recent years in the northern part of their range. infection by the chytrid fungus batrachochytrium dendrobatidis has been implicated in these declines. to determine whether antimicrobial peptides in the skin provide protection against this pathogen, norepinephrine-stimulated skin secretions were tested for their ability to inhibit growth of b. dendrobatidis in vitro. after concentration, crude mixtures of skin peptide ... | 2002 | 12237127 |
| falcaustra lowei n. sp. and other helminths from the tarahumara frog, rana tarahumarae (anura: ranidae), from sonora, mexico. | seventy-four specimens of falcaustra lowei n. sp. were recovered from the intestines of 9 of 42 (21%) tarahumara frogs. rana tarahumarae, from sonora, mexico. f. lowei is the 14th nearctic species to be described and belongs to that group of species possessing a pseudosucker, namely f. catesbeianae, f. chabaudi, f. chelydrae, f. mexicana, and f. wardi. the new species can be readily differentiated from these by the arrangement of caudal papillae and length of spicules. priority description of f. ... | 2001 | 11318564 |
