Decoding divergence in marine protistan communities: from strain diversity to basin biogeography
… of which dimensions of protistan genetic diversity translate to measurable phenotypic variation is needed to predict the impact of protists on marine biogeochemistry and protists’ environmental change sensitivity. I cultured twelve strains of the coccolithophore Gephyrocapsa huxleyi across …

Escherichia coli Strain Diversity in Humans: Effects of Sampling Effort and Methodology
… investigating <em>Escherichia coli</em> strain diversity and demographics in human hosts are frequently inconsistent regarding sampling effort and methodology while current strain typing methods are often expensive or laborious. To rectify these inconsistencies, sampling effort was …

The significance of strain diversity in the epidemiology of Camplobacter jejuni gastrointestinal infections
A polyphasic study of the population diversity in a collection of Campylobacterjejuni isolates involved in human disease and from animal and environmental sources was undertakert Isolates were characterised by phenotype, using heat stable antigen serotype, bacteriophage type and biotyping methods. …

Tick-borne haemoparasite occurrence and Anaplasma bovis strain diversity in eastern rock sengis (Elephantulus myurus)
… South Africa harbour an Anaplasma bovis-like strain, a rickettsial pathogen of cattle. Anaplasma bovis infects host monocytes causing monocytic- and bovine anaplasmosis. The role of rock sengi as reservoirs of tick-borne pathogens has not been fully investigated. In addition, the phylogenetic …

Tick-borne haemoparasite prevalence and Theileria parva strain diversity in African buffalo (Syncerus caffer) from northern Botswana and Gonarezhou National Park, Zimbabwe
… clade. In conclusion, this study highlights the diversity of haemoparasites present in African buffalo from northern Botswana and Zimbabwe and also the role of African buffalo as a sentinel species for livestock tick-borne pathogens. Important tick-borne haemoparasites identified in this study …

Cross-Seeding Potential of Misfolded Amyloid-Beta Strains On Tau Protein: Examining The Puzzle Pieces of Alzheimer'S Disease
… infectious prions, such as their conformational strain diversity. Prion strains trigger diseases that may substantially vary in their pathological and clinical aspects. One example of strain diversity in Aβ can be found in the synthetic 2F and 3F fibrils. These aggregates were originally …

Exploring Novel Immunodiagnostics for Prion Disease
… of our results, we posit that exploring PrPSc strain diversity with available anti-PrP antibodies will lead to the development of ultrasensitive qPCR-PLA Protein Assays for precise detection and quantification of particular PrPSc strains.

Molecular detection and characterization of Bartonella in small mammals from southern Africa
… In this study, we contrast prevalence and diversity of Bartonella infections in 377 small mammals, representative of three terrestrial rodent genera, namely Aethomys, Gerbilliscus and Rhabdomys and one subterranean mole-rat species (Bathyergus suillus). The latter was sampled in close …
