β-lactoglobulin is the major whey protein in ruminant milk. In sheep, three genetic variants have been found (A, B and C) which differ from each other by a single base substitution within exon II of the gene. Various reports have indicated that the B variant is associated with higher milk yields. In this study, we have assessed the genotypic frequencies of both A and B variants in samples from ...

conclusions the most predominant vaca genotypes in our areas were s1/m2 and s1/m1, which regard as the genotypes with more virulence intensity. the h. pylori vacas1a, caga genotypes have a significant relationship with the presence of pud and gc in iranian patients with dyspepsia. results in this study, vaca genotypes s1/m2, s1/m1, s2/m2 and s2/m1 were determined in 43.4%, 19.3%, 13.2% and 6% o...

the aim of this study was to detect the genotype of fasciola spp. in meshkin-shahr, ardabil province, northwestern iran in different hosts using pcr-rflp.the parasite hosts included cattle, and sheep. overall, 70 adult flukes from livers of slaughtered animals were collected from the abattoirs of aforementioned area. the included 35 samples from infected sheep and 35 samples from 35 infected ca...

Time temperature integrators (TTIs) are useful tools in estimating the heat load applied on differently processed dairy products. The objective of this study was to analyze and assess three TTIs - lactulose, furosine, and acid-soluble β-lactoglobulin (β-Lg) - in 70 high heated dairy products at retail in Austria and Germany comprising whipping cream, coffee cream/milk, and condensed milk produc...

The development of a new manufacturing process, a two-step temperature treatment, to modulate the physicochemical properties of nanoparticles including the size is critical. This is because its physicochemical properties can be key factors affecting the cellular uptake and the bioavailability of bioactive compounds encapsulated in nanoparticles. The aims of this study were to produce (beta-lact...

Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of Johne’s disease, an economically important disease in ruminants worldwide. It was first isolated in Egypt in 2005. Since then, the pathogen has been detected in different Egyptian provinces. In order to trace the source of infection, genotyping using simple methods of high discriminatory power such as mycobacterial inte...

background mycobacterium tuberculosis genotyping can effectively improve tuberculosis (tb) control programs by controlling disease transmission. pulsed field gel electrophoresis (pfge) is a particularly powerful tool for determination of clonal identity of bacteria providing information for understanding and controlling the spread of disease. objectives the aim of present study was to investiga...
