Genome codon bias analysis of dengue virus type 1

Dengue viruses (DENV) are the most common mosquito-borne RNA virus with high variation and adaptation in tropical and subtropical regions. Exploration of codon usage bias of DENV can be significant to understand their genetic variation and adaptation. In the study, the codon usage pattern of dengue virus type 1 (DENV-1) was analyzed by using codonW, CUSP and SPSS. The extent of codon preference of DENV-1 is weak with a...

Antibiotic resistance of enterobacteria (Escherichia coli, Klebsiella spp. and Salmonella spp) isolated from healthy poultry and pig farms in peri-urban area of Lome, Togo

This study aimed to determine for the first time the levels and patterns of antimicrobial resistance of enterobacteria isolated from poultry and pigs farms in southern Togo. A cross-sectional study was conducted in south Togo in 70 and 47 poultry and pig farms, respectively. Fecal samples were collected once in each farm and enterobacteria isolated according to recommended techniques. Isolates from each sample were...

Antibacterial abilities of spray sanitizer solutions formulated with chitosan and acid complexes at pH 3 on broiler carcass surfaces inoculated with selected pathogenic bacteria before refrigeration

Single acid (acetic acid, lactic acid, propionic acid and phosphoric acid) and acid complex solutions at the ratio 1:1 or 2:1 at pH 3 were investigated their antimicrobial activities against three selected foodborne pathogens (Escherichia coli, Salmonella typhi and Staphylococcus aureus). The influences of the deacetylation degrees (DD) (80% and 95%), concentrations (500, 1000, and 2000 μg/mL) and contact time (10,...
