Die ondersoek na spesifieke bakteriegroepe in die feses van geselekteerde proefpersone
… were identified and classified using different phenotypic tests. Quantitative analyses revealed that the composition of the bacterial populations differ from person to person. The total percentage anaerobes was 97,96%, while 2,04% were anaerobic and facultative anaerobic bacteria. Of the fifty …

The Production of 2-Keto-L-Gulonic Acid by Different Gluconobacter Strains
… gram-negative rods in DSM 4027 to 2-KLG. Limited phenotypic tests suggested that the gram-negative rods in the DSM 4027 mixture are not gluconobacters.

Oxidative stress responses in Campylobacter jejuni: the role of the Peroxide Regulator PerR
… gene was inactivated and characterised using phenotypic tests and transcriptomic investigations. We investigated the role of PerR in the regulation of oxidative stress defences in C. jejuni and demonstrated that a perR mutant has increased aerotolerance and survival against exposure to …

Random amplified polymorphic DNA (RAPD) analysis of Bacillus sphaericus
… from nonpathogenic strains based on simple phenotypic tests. DNA-DNA hybridizations performed in 1980 placed the 7 pathogens included in that study in a distinct homology group separate from 5 groups of nonpathogens. The overall homology of the pathogenic strains to the species type strain …

Detection and characterisation of carbapenem-resistant gram-negative bacilli infections in Ghana
… to detect carbapenemase activity by using simple phenotypic tests, molecular typing to characterise the resistance genes and to determine the relatedness of the CR isolates collected from different hospitals in the country. A total of 111 CR isolates were identified by disc diffusion …

Investigations of Carbapenem-resistant Klebsiella species and associated clinical considerations
… Klebsiella strains were characterised. Phenotypic tests identified the strains as Klebsiella pneumoniae (n = 36) and Klebsiella oxytoca (n = 3). Detailed whole-genome sequence (WGS) analyses showed the K.oxytoca were Klebsiella michiganensis and one of the K. pneumoniae strains to be …

Molecular Characterization of Fluoroquinolone Resistance in Streptococcus pneumoniae
… in the QRDRs, examine the role of efflux using phenotypic tests, and investigate the expression of several putative efflux pumps. The newer fluoroquinolone moxifloxacin was more active in vitro against S. pneumoniae than ciprofloxacin and selected fewer resistant mutants. The potency of …

Diversity of the butyrate-producing microflora of the human gut.
… were analyzed by conventional microbiology tests; of these isolates 74 produced significant amounts of butyrate. Phenotypic tests highlighted similarities of the isolates with the genera Eubacterium. Roseburia and Butyrivibrio, but these genera are not readily distinguishable at phenotypic …

Co-existence and niche separation of two subspecies of Photorhabdus temperata associated with Heterorhabditis downesi in a dune grassland
… nematode species (Chapter 2). In antibiosis tests against a range of organisms the P. temperata subsp. cinerea isolates had a greater inhibitory effect than the P. temperata subsp. temperata isolates. Only one pair of isolates, yel1 and pur2, showed any antibiotic activity against the other …
