The establishment of the etiology of low egg viability may ultimately lead to

a treatment modality to increase the hatching rate of this critically endangered species. Indeed, recent reports demonstrated that bacteria (Awong-Jaylor et al., 2008) and the Selleckchem ATM inhibitor fungus, Fusarium solani (Sarmiento-Ramirez et al., 2010), were responsible for/associated with failed loggerhead sea turtle eggs, making it clear that egg-associated pathogens are an area of concern for leatherback turtles. The Acinetobacter sp. HM746599 bacteria are available from the Culture Collection, University Gothenburg, Göteborg, Sweden (CCUG-600049), and from the Agricultural Research Service Culture Collection, Peoria, IL (NRRL-B-59471). We would like to thank Dr Richard Facalam

at the CDC, Washington, DC, for the analysis of several characteristics of the bacteria and Dr David Collins of the University of Reading, UK, for the initial partial sequencing of the rRNA gene in the bacteria. “
“The genome sequence of the organohalide-respiring bacterium Dehalogenimonas lykanthroporepellensBL-DC-9T contains numerous loci annotated as reductive dehalogenase homologous (rdh) genes based on inferred protein sequence identity with functional dehalogenases of other bacterial species. Many of these genes are truncated, lack adjacent regulatory elements, or lack cognate genes coding for membrane-anchoring proteins typical of the functionally characterized active reductive dehalogenases of organohalide-respiring bacteria. To investigate the expression patterns of the rdh genes in D. lykanthroporepellensBL-DC-9T, oligonucleotide primers were designed to uniquely target 25 rdh genes present in the genome as well as four putative regulatory genes. RNA extracts from cultures of strain BL-DC-9T actively dechlorinating three different electron acceptors, 1,2-dichloroethane, 1,2-dichloropropane, and 1,2,3-trichloropropane were reverse-transcribed and subjected to PCR amplification using rdh-specific primers. Nineteen rdh gene

transcripts, including Edoxaban 13 full-length rdhA genes, six truncated rdhA genes, and five rdhA genes having cognate rdhB genes were consistently detected during the dechlorination of all three of the polychlorinated alkanes tested. Transcripts from all four of the putative regulatory genes were also consistently detected. Results reported here expand the diversity of bacteria known to simultaneously transcribe multiple rdh genes and provide insights into the transcription factors associated with rdh gene expression. “
“The binary toxin ‘Photorhabdus insect-related’ proteins (PirAB) produced by Photorhabdus luminescens have been reported to possess both injectable and oral activities against a range of insects.
