Diversity of porcine reproductive and respiratory syndrome virus in Shandong, China.

Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most economically significant pathogens in swine industry of China. To study infection and genetic variation of PRRSV, 637 tissue samples were collected from diseased pigs in Shandong, and then subjected to detection of PRRSV. The nsp2 and ORF5 genes were sequenced for investigation of variations and phylogenetic analysis.

A Phage Lysin Fused to a Cell-Penetrating Peptide Kills Intracellular Methicillin-Resistant Staphylococcus aureus in Keratinocytes and Has Potential as a Treatment for Skin Infections in Mice.

is the main pathogen that causes skin and skin structure infections and is able to survive and persist in keratinocytes of the epidermis. Since the evolution of multidrug-resistant bacteria, the use of phages and their lysins has presented a promising alternative approach to treatment. In this study, a cell wall hydrolase (also called lysin) derived from phage JD007 (JDlys) was identified.

Anti-anaemia efficacy of β-lactoglobulin hydrolysate-iron complex on iron-deficient anaemic rats.

Purpose: The effects of orally administered β-lactoglobulin hydrolysate-iron complex (β-LGH-Fe) on haematological and biochemical parameters in anaemic rats were evaluated. Female weaning Sprague-Dawley rats were fed with iron-deficient diet to induce iron deficiency anaemia. After 6 weeks, the obtained anaemic rats were divided into five groups: iron deficiency control group (iron-deficient diet without β-LGH-Fe complex supplementation, IDC); three groups supplemented with different dosages of β-LGH-Fe complex (0.
