Our R. africae 16S rRNA sequences grouped with R. africae isolates from Nigeria, Egypt and Benin. The information on tick species diversity and pathogens in the various tick species provides an indicator of potential transmission amongst cattle populations, and to humans, and can be useful to estimate disease risk and in control strategies.This study investigated the possibility of detecting Mycobacterium tuberculosis (MTB) in blood-stained sputa with GeneXpert assay (Xpert MTB/Rif G4 v.5) using appropriate blood lysing (distilled water and distilled water/carbon tetrachloride) and protein denaturing (guanidinium chloride and heat) agents. Blood free sputa were collected from individuals infected with MTB. Various levels of blood-spiked sputa (0%-50%) were prepared and subsequently assayed with GeneXpert analyzer. GeneXpert was found to be reproducible at less than 2% blood contamination. However, beyond 5% blood contamination, GeneXpert was unreliable with absolute PCR inhibition at 20% of blood contamination. Boiling at 95°C for 5 minutes was able to recover MTB DNA in previously undetectable levels as well as in 57% of patients' sputa with blood stains with previous negative GeneXpert results.Tailings are among the most challenging mined substrates for plant re-establishment, in particular because of a lack of soil-like structure and nitrogen. Potential pioneer plants are sometimes found in such disturbed and infertile sites. We present a group of pioneer species from the genus Maireana (Chenopodiaceae) that are promising candidates for the restoration of magnetite tailings. We found that these Maireana species did not rely on biologically fixed N from the atmosphere, but exhibited an exceptionally high leaf N-resorption efficiency (about 95%) during leaf senescence, at the same
