Tetrodotoxin and its analogue 6-epitetrodotoxin in newts (Triturus spp.; Urodela, Salamandridae) from southern Germany.
Tetrodotoxin (TTX) and its analogue 6-epitetrodotoxin (6-epiTTX) were quantitatively assayed in 59 newts representing four Triturus species (Triturus alpestris, Triturus cristatus, TriturusExpand
Clinical Characteristics Associated with Isolation of Small-Colony Variants of Staphylococcus aureus and Pseudomonas aeruginosa from Respiratory Secretions of Patients with Cystic Fibrosis
ABSTRACT During a 3-month period, small-colony variant phenotypes of both Staphylococcus aureus and Pseudomonas aeruginosa were isolated from respiratory secretions of 8.2% and 9.2%, respectively, ofExpand
Aristolochic acid content of South-East Asian troidine swallowtails (Lepidoptera: Papilionidae) and of Aristolochia plant species (Aristolochiaceae)
SummaryAnalysis of South-East Asian troidine swallowtails revealed high variability in the content of aristolochic acids among individuals. The presence or absence of these compounds depends on theExpand
Cantharidin and demethylcantharidin (palasonin) content of blister beetles (Coleoptera: Meloidae) from southern Africa.
In two species of meloid beetles, Hycleus oculatus and Hycleus tinctus, from southern Africa, cantharidin and demethylcantharidin (palasonin) were assayed quantitatively. For cantharidin the meanExpand
Studies on the cardenolide sequestration in African milkweed butterflies (Danaidae).
Butterflies of the Danaidae family are considered to be toxic or distasteful due to the presence of cardiac glycosides sequestered from their larval food plants. Alcoholic extracts of specimens ofExpand
First report of Coniella hibisci causing leaf and stem canker in the Lao P.D.R.
Coniella hibisci is reported for the first time in Lao P.D.R. The pathogen was isolated from roselle (Hibiscus sabdariffa var. sabdariffa) stem and leaf samples from a farm in Thateng district,Expand
Molecular studies on the ouabain binding site of the Na+, K+-ATPase in milkweed butterflies
Summary. The Na+, K+-ATPase of the Monarch butterfly (Danaus plexippus) is insensitive to the inhibition by cardiac glycosides due to an amino acid replacement: histidine instead of asparagine atExpand
Evading plant defence: Infestation of poisonous milkweed fruits (Asclepiadaceae) by the fruit fly Dacus siliqualactis (Diptera: Tephritidae)
ABSTRACT To cope with toxic metabolites plants use for defence, herbivorous insects employ various adaptive strategies. For oviposition, the fruit fly Dacus siliqualactis (Tephritidae) uses milkweedExpand
