Strategy for the identification of micro-organisms producing food and feed products: Bacteria producing food enzymes as study case

*; Nancy Roosens * Source: Food Chemistry, Volume 305 (2020) Keywords: 16S-rRNA gene sequencing bacteria Food enzymes identification PCR technology Producing organisms SCREENING Abstract: Recent ...

Molecular epidemiology and antimicrobial resistance mechanisms of Campylobacter coli from diarrhoeal patients and broiler carcasses in Belgium.

isolates, the tet(O) gene among tetracycline-resistant isolates and the 23S rRNA A2075G mutation among erythromycin- resistant isolates. Furthermore, some erythromycin-resistant isolates harboured a diverse ...

Genetic Basis and Clonal Population Structure of Antibiotic Resistance in Isolated From Broiler Carcasses in Belgium.

most but not all resistant isolates. Regarding resistance to erythromycin, different mutations occurred in diverse genetic loci, including mutations in the 23S rRNA gene, the and ribosomal genes, and the ...

Nucleotide Sequence Database Comparison for Routine Dermatophyte Identification by Internal Transcribed Spacer 2 Genetic Region DNA Barcoding.

Abstract: Conventional dermatophyte identification is based on morphological features. However, recent studies have proposed to use the nucleotide sequences of the rRNA internal transcribed spacer (ITS) ...

Frequency of Mycobacterium chimaera among Belgian patients, 2015.

intracellulare. We performed a re-analysis of the 149 M. intracellulare strains received by the Belgian National Reference Laboratory using 16S rRNA gene sequencing, representing 25 % of all NTM collected in 2015. ...

Development of a Luminex xTAG® assay for cost-effective multiplex detection of β-lactamases in Gram-negative bacteria.

probe targeting a conserved 16S rRNA region serving as a DNA extraction control. The assay was optimized using a collection of 48 reference strains and further validated using 105 foodborne ESBL-producing ...

Evaluation of the Speed-Oligo Mycobacteria assay for the identification of nontuberculous mycobacteria.

identification were reassessed by the Speed-Oligo Mycobacteria assay and resolved by the GenoType Mycobacterium CM assay and by sequencing of 16S rRNA and protein-encoding genes. We found 93.5 % (58/62) ...

Establishing mono-eukaryotic Histomonas meleagridis cultures from in vivo infection contaminated with Tetratrichomonas gallinarum and Blastocystis spp.

Additionally, TEM examination and analysis by PCR amplification of the small subunit rRNA gene could exclude the co-cultivation of T. gallinarum and Blastocystis spp. Furthermore, after successful propagation and ...

The dermatophyte species Arthroderma benhamiae: intraspecies variability and mating behaviour.

benhamiae wild strains from the same geographical area (Switzerland) was studied by comparing their morphology, assessing their molecular variability using internal transcribed spacer (ITS) and 28S rRNA gene ...

Characterization of Selenaion koniopes n. gen., n. sp., an amoeba that represents a new major lineage within heterolobosea, isolated from the Wieliczka salt mine31206

that was covered with small granules. Pore plugs had a flattened dome shape, were bipartite, and penetrated only the endocyst. Phylogenies based on the 18S rRNA gene and the presence of 18S rRNA helix ...
