Infection by multidrug-resistant avian pathogenic Escherichia coli (APEC) in chickens always leads to the uselessness of antibiotics, highlighting the need for alternative antibacterial agents. Sophora flavescens and Coptis chinensis have been a classical combination used together in Traditional Chinese Medicine (TCM) formulas to treat diseases with similar symptoms to colibacillosis for an extended period, but the effect of their active ingredients' combination on APEC infection remains unstudied. The objective of this study was to explore the synergistic effect of matrine and berberine hydrochloride on colibacillosis caused by an isolated multidrug-resistant APEC.

In pet clinics, the number of cases using trauma drugs accounts for >10% of the total number of cases, and most wounds are healing by second intention. The prolongation of wound healing time causes inconvenience and burden to pets and pet owners. Therefore, how to reduce wound healing time and achieve maximum recovery of tissue function and aesthetics is one of the focuses of veterinary clinical practice.

Dairy cows experience hypocalcemia at the onset of lactation; however, the contribution of bone metabolism to circulating Ca concentrations during the periparturient period is not well understood. Osteoprotegerin (OPG) protects against loss of skeletal mass by regulating osteoclastogenesis. We previously reported that the bone resorption increased around parturition in dairy cows from the perspective of bone markers in blood.

Muscovy duck parvovirus (MDPV) infection is widespread in many Muscovy-duck-farming countries, leading to a huge economic loss. By means of overlapping peptides expressed in Escherichia coli in combination with Western blot, antigenic domains on the non-structural protein (NSP) of MDPV were identified for the first time. On the Western blot, the fragments NS(481-510), NS (501-530), NS (521-550), NS (541-570), NS (561-590), NS (581-610) and NS (601-627) were positive (the numbers in parentheses indicate the location of amino acids), and other fragments were negative.
