Abstract This study aimed at characterizing groundwater evolution using hydrogeochemical facies and signatures in two basins with contrasting climate geology, one the central part other eastern coast of Tanzania. The Kimbiji (humid, unconsolidated) aquifer is covered by an unconfined layer upper parts a confined lower parts, strong artesian flow characteristics while Singida (semi-arid, consoli...

Background: Vaccination is the most fundamental strategy in control and eradication of brucellosis. Several vaccination programs with different vaccines have been carried out many countries which brucellosis continues to be a problem livestock. One recommended against cattle live Brucella abortus S19 vaccine. The aim this study evaluate results field safety efficacy trials for conjunctival vacc...

The CLSI M100-S19 document has recommended the disuse of vancomycin disks for staphylococci and informed that studies on the action of teicoplanin in disk-diffusion testing should be performed. We describe the comparison of two methods, disk diffusion and broth microdilution, for determining teicoplanin susceptibility in clinical isolates of staphylococci. Overall results showed an aggregation ...

Poly-A+ mRNA from Xenopus laevis oocytes, partially enriched for r-protein coding capacity has been used as starting material for preparing a cDNA bank in plasmid pBR322. The clones containing sequences specific for r-proteins have been selected by translation of the complementary mRNAs. Clones for six different r-proteins have been identified and utilized as probes for studying their genomic o...

Brucella abortus rough lipopolysaccharide (LPS) mutants were obtained by transposon insertion into two wbk genes (wbkA [putative glycosyltransferase; formerly rfbU] and per [perosamine synthetase]), into manB (pmm [phosphomannomutase; formerly rfbK]), and into an unassigned gene. Consistent with gene-predicted roles, electrophoretic analysis, 2-keto-3-manno-D-octulosonate measurements, and immu...
