Molecular Phylogenetic Analysis of Novel Spiroplasma Isolates
… approach that focused on serologically distinct isolates from a single host family was used as an initial step in understanding spiroplasma diversity and distribution. Tabanid-associated spiroplasmas represent the most thoroughly studied group to date, so this project examined a spiroplasma field …

Diversity of acinetobacter baumannii isolates from Egypt
… an overall similarity at only 28.69% between the isolates, with variation in pattern for isolates with similar blaOXA-51-like genes. Typing with Multilocus Sequence Typing (MLST) identified 6 new Sequence Types: ST408 - ST414, in addition to ST331 and ST108 which have been previously found in …

Genetic diversity of African isolates of Toxoplasma gondii
… genetic variation among local African T. gondii isolates in relation to theirphenotype (genotype phenotype relationships). In this study, multi-locus nested PCRsequence analysis of seven Ugandan T. gondii isolates was applied using nine differentgenetic markers distributed across seven …

Characterization and protein fingerprinting of Botrytis cinerea isolates /
Botrytis cinerea isolates collected from Niagara region were treated with different concentrations of the fiingicide, iprodione to test their sensitivity to this fungicide. These Botrytis cinerea isolates were divided into two groups according to their sensitivity to iprodione. Those isolates whose …

Sympatric Soil Microbe Interactions between Streptomyces and Fusarium Isolates
… <em>Streptomyces</em> and <em>Fusarium</em> isolates from disease suppressive soils were investigated in this study. Dual layer agar inhibition assay revealed inhibition of <em>Streptomyces</em> by <em>Fusarium</em> in all pairwise combinations, while only 46% of pairwise combinations showed …

Enzyme Mediated Gentamicin Resistance Among Gram-Negative Clinical Isolates
… of resistance to gentamicin among clinical isolates (of formerly susceptible bacteria) is on the rise (7-12). Resistance to the aminoglycosides is believed to be due to three basic mechanisms (13,14), The best characterized mechanism is the enzyme-mediated inactivation of antibiotic …

Ornithobacterium hominis isolates from a South African birth cohort
… characteristics of the South African O. hominis isolates were determined and antibiotic susceptibility determined. For whole genome sequencing, DNA was extracted, assessed for quality, and sequenced using the Oxford Nanopore technologies platform. Genomes were assembled using an in-house …

A serological study of some cauliflower mosaic virus isolates
… Small serological differences between CaMV isolates could be shown by ELISA and serum cross-absorption. Serological reactivity of CaMV was found to depend on the proteolytic degradation state of the virus coat protein so making it impossible to establish definite serological relationships …

The morphology, ecology and fungicidal tolerance of Botrytis cinerea isolates
Field isolates of Botrytis cinerea Pers. from tomato crops gave rise to two distinct morphological types after successive single spore isolations; type 1 (T1) characterised by regular, rapidly growing mycelium and type 2 (T2) characterised by sparse, often distorted, slow growing mycelium. The …

Characterization of probiotic Lactobacillus spp. isolates from commercial fermented milks
… and also possible functional properties of the isolates, such as antimicrobial activities, antibiotic resistance/susceptibility and antibiotic resistance genes, biofilm formation and production of conjugated linoleic acid (CLA). Primarily, a comparative study was carried out on selectivity of …

Fingerprinting and characterisation of Escherichia coli isolates using DNA arrays
… from the ECOR collection, and 49 clinical isolates. A wide range of E. coli pathogenicity markers was detected. The pathogenicity markers that were most common include chuA and iucC, which are both involved in iron metabolism. Additionally, the clinical isolates were grouped into clusters …

Diagnostic characterization of Malassezia pachydermatis isolates from canine otitis externa
… was emerging in M. pachydermatis clinical isolates. To identify the isolates and further characterize them, conserved loci were sequenced, phylogenetic analysis was performed, matrix-assisted laser/desorption ionization time-of-flight mass spectrometry (MALDI-ToF MS) identification was …
