The hydrophilic proteins of lung surfactant as a prognostic marker in experimental pneumonia

Abstract BACKGROUND: SP-A and SP-D are hydrophilic proteins which regulate the inflammatory response of the lung. Pasteurella multocida is one of the most common bacteria isolated from calves suffering from shipping fever pneumonia, one of the most problems in dairy herds. OBJECTIVE: Evaluation of surfactant content may provide a valuable diagnostic tool for detection of calf pneumonia due to ...

Research Article: Investigating the effect of water filter made using polyurethane foam containing silver nanoparticles on controlling Yersinia ruckeri in Oncorhynchus

The aim of this study was to evaluate the efficiency of polyurethane foam containing silver nanoparticles synthesized by Verbena officinalis leaf extract in controlling of Yersinia ruckeri in treatment of water tanks of rainbow trout farming. Biosynthesis of silver nanoparticles is done with 2mM silver nitrate solution and Verbena officinalis extract. To study antibacterial effects of the produ...

Revision of Hemiquedius Casey (Staphylinidae, Staphylininae) and a review of beetles dependent on beavers and muskrats in North America

Based on newly discovered characters on the male genitalia, external morphology and an accumulation of ecological data, we revise the single member of the genus Hemiquedius. Two new species, H. infinitus Brunke & Smetana, sp. n. and H. castoris Brunke & Smetana, sp. n., from eastern North America are described, and H. ferox (LeConte), restricted to peninsular Florida, is re-described. Hemiquedi...

Study of synergistic Effects of potassium- sorbate and Lactobacillus casei on The activity of digestive enzymes, intestinal Histomorphology and resistance against pathogenic bacteria (Yersinia ruckeri) in rainbow trout fry (Oncorhynchus mykiss)

Today in aquaculture to prevent negative effects of antibiotics The use of alternative, such as probiotics, prebiotics, organic acids, That can have positive effects on fish physiology activities. This study in order to done the synergistic effects of organic acid (potassium sorbate) and probiotic (Lactobacillus casei) in rainbow trout fry (Oncorhynchus mykiss). For this purpose of 360 pieces o...
