this study aimed at applying both growth and survival approaches to compare three native strains of lactobacilli, belonging to lactobacillus plantarum, lactobacillus rhamnosus and lactobacillus acidophilus species, with two commercial probiotic strains in their tolerance to acid and bile. the association between the data obtained from the methods was studied.  the results of the different metho...

A study was undertaken to evaluate the reproductive performance in two plumage colour variant strains of quail, viz; Brown, White Breasted and a dark Cinnamon Brown (commercial) strain. A total of 694 straight run active chicks were obtained in three hatches at weekly intervals from the three strains. Sex was determined at six weeks of age and female progenies were separated and data on reprodu...

The objective of this study was to assess the importance of strain and sex and their interaction effect on broiler chickens’ performance and susceptibility to ascites. Chicks from three strains (Ross 308, Cobb 500 and Arian, labeled as A, B and C respectively) were obtained from the same age breeder and sexed when one-day-old. Each crosses’ sex was assigned to four pens of 60 broilers each. Bod...

The use of liposome as an adjuvant and a vaccine carrier has been cited previously in the literature. It has also been shown to be effective in enhancing the immunogenicity of vaccine candidates. BALB/c mice immunized subcutaneously with outer membrane protein (OMP) of Brucella abortus S19 vaccine strain entrapped in a commercial cationic liposome (S19-OMP-liposome) for vaccine delivery, showed...

The yeast strains that are resistant to high concentration of ethanol have biotechnological benefits and aresuitable models for physiology and molecular genetics research fields. A novel ethanol-tolerant mutant strain,mut1, derived from the commercial Saccharomyces cerevisiae showed higher ethanol production, and alsodemonstrated resistance to ethanol but not to other alcohols...

Escherichia coli strain BL21 is one of the widely used bacterial hosts for high-level recombinant protein production and for other applications. Here, we present the complete genome sequence of a commercial version of the Escherichia coli BL21 strain.

Escherichia coli strain WG5 is a widely used host for phage detection, including somatic coliphages employed as standard ISO method 10705-1 (2000). Here, we present the complete genome sequence of a commercial E. coli WG5 strain.
