The complex multicellular morphology of the food spoilage bacteria Brochothrix thermosphacta strains isolated from groun...
Published in Canadian journal of microbiology
Herein we describe a highly structured, filamentous growth phenotype displayed by an isolate of the food spoilage microorganism Brochothrix thermosphacta. The growth morphology of this B. thermosphacta strain (strain BII) was dependent on environmental factors such as the growth media, incubation temperatures, and the inoculum concentration. Inocul...
Rumen bacterial diversity of Tibetan sheep (Ovis aries) associated with different forage types on the Qinghai-Tibetan Pl...
Published in Canadian journal of microbiology
Diet is the great determinant of bacterial composition in the rumen. However, little is known about the rumen bacterial community of Tibetan sheep living in the special ecological environment of the Qinghai-Tibetan Plateau (QTP) of China. In the present study, we used high-throughput sequencing to investigate the rumen bacterial community of Tibeta...
Effect of common bean seed exudates on growth, lipopolysaccharide and lipopolysaccharide transport gene expression of Rh...
...Published in Canadian journal of microbiology
Lipopolysaccharide (LPS) is essential for successful nodulation during the symbiosis of rhizobia and legumes. However, the detailed mechanism of the LPS in this process has not yet been clearly elucidated. In this study, the effects of exudates the common bean seeds on the growth, lipopolysaccharide production and lipopolysaccharide transport genes...
Persistent contamination of Salmonella, Campylobacter, Escherichia coli and Staphylococcus aureus at a Broiler Farm in N...
Published in Canadian journal of microbiology
Intensive poultry production due to public demand raises the risk of contamination, creating potential foodborne hazards to consumers. The prevalence and microbial load of pathogens Campylobacter, Salmonella, S. aureus and E. coli was determined by standard methods at the farm level. After disinfection, swab samples collected on wall crevices, drin...
Continuing surveillance of invasive Haemophilus influenzae disease in northwestern Ontario emphasizes the importance of ...
Published in Canadian journal of microbiology
In the post-Haemophilus influenzae serotype b (Hib) vaccine era, invasive H. influenzae serotype a (Hia) disease emerged in Canadian First Nation, Inuit, and Alaskan Indigenous populations. Previous studies by our group found a high incidence of invasive Hia disease in northwestern Ontario. We retrospectively reviewed 24 cases (4 pediatric and 20 a...
The evolving nature of Bordetella pertussis in Ontario, Canada, 2009-2017: strains with shifting genotypes and pertactin...
...Published in Canadian journal of microbiology
This study examined the evolving nature of Bordetella pertussis in Ontario, Canada, by characterizing isolates for their genotypes and expression of pertactin (PRN). From 2009 to 2017, 413 B. pertussis were cultured from pertussis cases at the Public Health Ontario Laboratory. Their genotypes were determined by partial gene sequence analysis of the...
Control of pathogens in fresh pork sausage by inclusion of Lactobacillus sakei BAS0117.
Published in Canadian journal of microbiology
A pork sausage was produced with low sodium content (1.64%) to which Lactobacillus sakei was added with the aim of developing a meat pork sausage for cooking and having technological, organoleptic, and hygienic advantages. The lactic acid bacteria (LAB) L. sakei, Lactococcus sp., and Pediococcus pentosaceus were submitted to extreme pH, temperature...
Development and application of DNA-aptamer-coupled magnetic beads and aptasensors for the detection of Cryptosporidium p...
Published in Canadian journal of microbiology
Environmentally stable and disinfectant-resistant oocysts of Cryptosporidium spp. shed in the feces of infected humans and animals frequently contaminate water resources and are subsequently spread via potable and recreational waters. The current monoclonal-antibody-based methods for detecting them in water are slow, labor-intensive, and demand ski...
Effect of peptidases secreted by the opportunistic pathogen Scedosporium aurantiacum on human epithelial cells.
Published in Canadian journal of microbiology
Peptidases secreted by a clinical high-virulence Scedosporium aurantiacum isolate (strain WM 06.482; CBS 136046) under normoxic and hypoxic conditions were separated via size-exclusion chromatography, and peptidase activities present in each fraction were determined using class-specific substrates. The fractions demonstrating peptidase activity wer...
