Physical and chemical characteristics of yoghurt produced from whole milk with different levels of somatic cell counts.

For yoghurts were made from milk with different levels of somatic cell count (SCC) (low 95,000 cells ml(- 1), intermediate 398,000 cells ml(- 1) and high 1,150,000 cells ml(- 1)). Yoghurt samples were analysed for the degree of proteolysis, lipolysis (free fatty acid (FFA) content), acidity, pH and apparent viscosity on days 1, 14 and 28. The SCC had no significant effect (p>0.

Analysis of cassava brown streak viruses reveals the presence of distinct virus species causing cassava brown streak disease in East Africa.

Cassava brown streak virus (CBSV) isolates were analysed from symptomatic cassava collected between 1997 and 2008 in the major cultivation regions of East Africa. An analysis of complete RNA genomes of seven isolates from Kenya, Tanzania, Mozambique, Uganda and Malawi revealed a common genome structure, but the isolates clearly clustered in two distinct clades. The first comprised isolates from Kenya, Uganda, Malawi, north-western Tanzania and the CBSV described previously, and shared between 87 and 95% nucleotide sequence identity, whilst the second included isolates from coastal regions of Mozambique and Tanzania, which shared only 70% nucleotide sequence identities with isolates of the first clade.

A sentinel function for teat tissues in dairy cows: dominant innate immune response elements define early response to E. coli mastitis.

Escherichia coli intramammary infection elicits localized and systemic responses, some of which have been characterized in mammary secretory tissue. Our objective was to characterize gene expression patterns that become activated in different regions of the mammary gland during the acute phase of experimentally induced E. coli mastitis.

Enhanced host immune recognition of mastitis causing Escherchia coli in CD-14 transgenic mice.

Escherchia coli causes mastitis, an economically significant disease in dairy animals. E. coli endotoxin (lipopolysaccharide, LPS) when bound by host membrane proteins such as CD-14, causes release of proinflammatory cytokines recruiting neutrophils as an early, innate immune response.

Evaluation of breed-dependent differences in the innate immune responses of Holstein and Jersey cows to Staphylococcus aureus intramammary infection.

Mastitis is one of the most prevalent diseases of cattle. Various studies have reported breed-dependent differences in the risk for developing this disease. Among two major breeds, Jersey cows have been identified as having a lower prevalence of mastitis than Holstein cows.
