Widespread Natural Occurrence of Hydroxyurea in Animals
Here we report the widespread natural occurrence of a known antibiotic and antineoplastic compound, hydroxyurea in animals from many taxonomic groups. Hydroxyurea occurs in all the organisms we have examined including invertebrates (molluscs and crustaceans), fishes from several major groups, amphibians and mammals. The species with highest concentrations was an elasmobranch (sharks, skates and...
متن کاملAnaerobic oxalate degradation: widespread natural occurrence in aquatic sediments.
Significant concentrations of oxalate (dissolved plus particulate) were present in sediments taken from a diversity of aquatic environments, ranging from 0.1 to 0.7 mmol/liter of sediment. These included pelagic and littoral sediments from two freshwater lakes (Searsville Lake, Calif., and Lake Tahoe, Calif.), a hypersaline, meromictic, alkaline lake (Big Soda Lake, Nev.), and a South San Franc...
متن کاملOccurrence of Yersinia enterocolitica in wild animals.
Yersinia species were isolated from 16 of 495 small wild animals and from 1 of 38 foxes. The animals were trapped in seven regions of Hokkaido, Japan. Of the 17 strains isolated, 9 were Yersinia enterocolitica O6; 2 were Y. enterocolitica O5A; 1 was Y. enterocolitica, O4; 1 was Y. enterocolitica O9; 1 was Yersinia pseudotuberculosis IVB; and 3 were sucrose-negative strains. Yersinia pestis was ...
متن کاملThe widespread occurrence of tRNA‐derived fragments in Saccharomyces cerevisiae
Short RNAs derived from the cleavage of tRNA molecules are observed in most organisms. Their occurrence seems to be induced by stress conditions, but still little is known about their biogenesis and functions. We find that the recovery of tRNA fragments depends on the RNA isolation method. Using an optimized RNA extraction protocol and northern blot hybridization technique, we show that the tRN...
متن کاملWidespread occurrence of the micro-organism Wolbachia in ants.
For more than 20 years, sex allocation in hymenopteran societies has been a major topic in insect sociobiology. A recurring idea was that relatedness asymmetrics arising from their haplodiploid sex determination system would lead to various parent-offspring conflicts over optimal reproduction. A possible weakness of existing theory is that only interests of nuclear genes are properly accounted ...
